A SQUARE INCH OF IRON.
[For the Machinists and Blacksmiths' Journal.]
TN my last, I promised to give ^your readers an explanation of the " parallel motion," but a pressure of business has pre- vented it ; I will endeavor to do so in the next Journal.
The above caption has no doubt been studied by most all your readers; but, perhaps, another glance at it would do no harm. We are told a square inch of iron will sustain a strain of from 51,000 to 60,000 pounds if applied in the direction of its length; and Prof. Leslie tells us that a soft bar of iron one inch square and 1,000 inches long, loaded at the end with 36,000 pounds will stretch 1 inch, or ToVo part .of its length ; with 45,000 pounds it will stretch 2 inches, or j^ of its length ; with 54,000 pounds it will stretch 4 inches, or ^o of its length ; with 63,000 pounds it will stretch 8 inches, or T^T of its length ; and
with 72,000 pounds it will stretch 16 inches— and break after stretch- ing 16 inches — or -g^ or T|j of its length.
These experiments are of great value to the comprehensive mind of the mechanic, for from the data thus given it will show the factor of strength for perfect safety. We see that the first 36.000 pounds stretched the bar of iron 1,000 inches long 1 inch, making the bar 1,001 inches long ; it will also be seen that the fibers of the iron were started from their original compactness by the stretching; but Prof. Leslie goes on stretch- ing his bar of iron until it breaks at 72,000 pounds, having stretched it 16 inches. It must also be borne in mind that this was a soft bar of iron, prepared for the purpose, and one of a harder grain would not have been so easily stretched, and might perhaps have broken sooner, and with less warning, in case it was in machinery.
As we have already stated, a good piece of wrought iron will sustain a strain of from 54,000 to
370
Machinists and Blacksmiths'
60,000 pounds ; so, also, have we seen that Professor Leslie's bar stretched the first inch with only 36,000 pounds upon it, and we maintain that after a piece of iron is once stretched, if it be used in mechanics or machinery, con- tinual strain of only 36,000 pounds will break it sooner or later.
From these deductions we may say that 36,000 pounds will be too much for a constant strain to be put upon each square inch of iron. The next question that naturally suggests itself is, how much can we put on with perfect safety ? One of our favorite authors tells us that 4,000 pounds is quite suffi- cient to put on in such works as steam engines, where the motion is back and forth, like the piston of a steam engine, or where the strain is alternate ; but we have seen good results where the strain has exceeded 80,000 pounds per square inch of section. This is rather a higher figure than we would recommend, and in our own practice we generally aim to have our strain not to exceed 6,500, and in some cases even only 5,500 pounds, and where the iron is subject to shocks or extreme pressures put upon it, in rapid motion, we take a still less figure, according to the circumstances of the case.
Now, having stated the tensile strain, we may say that the crush-
ing strain is generally accepted in round numbers to be 27,000 pounds, or generally one-half of the strain it will bear in the di- rection of its length for wrought iron ; but cast iron is of a different nature respecting its tensile strength and crushing point. Cast iron will bear in the direction of its length only from 15,000 to 19,000 pounds, but its crushing weight is 98,982, or very nearly 100,000 pounds per square inch. Therefore, if we want a safe work- ing strain on a piece of cast iron we must, as in the case of wrought, put about one-eighth (-£) of its breaking strength upon it, or say about 2,000 pounds per square inch of section. Knowing all these things we have but to apply them as best suits the case. For instance, if we have a large weight to raise, of say 6,000 pounds, by means of a piece of cast iron, or by its being attached to a piece of cast iron, we know that we must not put over 2,000 pounds per square inch upon it; therefore we shall need 3 square inches to do the work ; and if we use a piece of round iron it will require to be about 2 inches in diameter, for a 2 -inch piece of round iron con- tains 3.1416 inches, which will be ample for all practical purposes for raising a weight of 6,000 pounds. If we want to raise the same weight with a piece of round

wrought iron, or square iron, a piece of 1| round, or 1 inch square, will do it. This, of course, is to be pulled in the direction of its length. Or, if we had a hoisting- engine of 8 horse-power, and it was required to lift its full capa- city every time, then we require to know how large a chain or rod would be needed. Here we have 8 horsepower, or 8 times 33,000, which is divided by 6,500, and we find we require 40 inches of iron, or a round rod of 7T2o inches dia- meter. This, of course, would stand all shocks necessary to put upon it, and be fully large enough for anything that might ever be expected to occur.
Thus far we have dealt only with the tensile or crushing strain ; we will now deal with the torsion or twisting strain. To begin: A piece of lead 1 inch square can be twisted off with 44 pounds on the end of a lever one foot long. Try this some noon in the shop, and that will be the beginning of a series of the best experiments. You can place the lead in a vise, make a wrench a foot long, as light as possible, attach a weight of 44 pounds on it, let it fall, and mark the results. Thus there will be an experiment that all and any one can do for himself. A piece of tin will bear 1.4 as much as lead ; therefore to find the point at which a piece of tin will twist
off — lead being 1 — we have only to multiply 44 by 1.4 and we have 79.6 pounds that it will require at the end of the lever one foot long to twist off a square inch of tin. Copper is 4.3 of lead ; therefore we have 4.3 times 44, which will be 189.2 pounds, that it will re- quire to twist off a square inch of copper. Try this in the vise — a good large vise will stand it. Yellow brass is 4.6 of lead ; again we multiply 44 of lead by 4.6 for yellow brass and we have 202.4 pounds that will twist off a square inch of yellow brass. Gun metal is 5 of lead ; therefore 5 times 44 equals 220 pounds it will require to twist off a square inch of gun metal — generally 9 of copper and 1 of tin. Cast iron is 9 of lead ; therefore 9 times 44 equals 396 pounds that will be required to twist off a square inch of cast iron. This can be tried in the shop at noon ; by a very little in- genuity a square piece of cast iron can be made fast to some place in the shop, or perhaps it might be bolted on a planer bed or fixed in some heavy casting in the shop. Try it; a great many carry their dinners and have some time to spare ; I have done it my- self when I worked in the shop and carried my dinner. Swedish iron is 9.5 of lead, so that 9.5 mul- tiplied by 44 gives 418 pounds that it will require to twist off a
372
Machinists and Blacksmiths'*
square inch of Swedish iron. Eng- lish iron is 10.1 of lead ; therefore it will require 10.1 times 44 to twist off a square inch of English iron, which will be 444.4 pounds. Blistered steel is 16.6 of lead; therefore it will require 16.6 times 44 to twist off a square inch of blistered steel, or 730.4 pounds. Shear steel is 17 of lead; there- fore 17 times 44 pounds will be required, or 748 pounds, to twist off a square inch of shear steel. Cast steel is 19.5 of lead, and therefore will require 19.5 times 44 pounds, or 858 pounds to twist it off.
Thus it will be seen the relation of one metal to another may easily be found if looked after, and when once found it can be applied in this way at any time the student of mechanics may see fit to apply it. J. J. Illingworth.
TABLE OP THE TEETH OF WHEELS.
BY THE LATE MR. ROBERT ADCOCK, C. E.
A Wisconsin man has invented a railroad switch that will adapt itself to a coming train and never be out of place. The Milwaukee Wisconsian says that it has stood a practical test,working perfectly. This will, if the report be true, lessen materially the danger of railroad travel, and win for the inventor nearly as much praise as if he had devised a switch that would cause the instant death of the man who carelessly left it open.
Seek in the tables, and on the same line with 30, in column 1, will be found 1.144, in column 6, which, multiplied by 2£ in., gives 2.S6 in. For 1.144X2^ = 2.860; therefore, 2.86 in., or 2| in., is the distance for describing the flanks of the teeth.
With the compasses open to that extent, move one leg along the "paths of centers" last described until the point of the other leg touches the face of the tooth which is to be drawn on the " pitch cir- cle ;" then, by drawing downward from the pitch circle, and from that point of the face, the flank of one side of the tooth will be de- scribed. It must be remembered, in this instance, that it is the side of the flank of the tooth nearest to you that you are about to draw ; and that the tooth lies without the compasses, and not within, as was the case while drawing the faces of the teeth.
The whole of the faces and flanks of the teeth being drawn, the next thing is to draw their heights — a very good proportion for which is five-tenths of the pitch ; two-tenths being |he heights of the faces, and three- tenths that of the flanks to the roots. Draw a line from the cen- ter of the wheel to without the

pitch circle, and on this line mark, within and without the pitch cir- cle, the proper heights of the teeth both top of the face and root of the flank. Draw circles passing through those points, which mark the heights of the teeth.
Bule. — Seek in the first column for the number of teeth it is pro- posed that the wheel shall con- tain. In a line with such number of teeth, take from columns 2, 3, 4, 5, and 6, the numbers that are in them ; and in every case mul- tiply such numbers by the pitch. The products will be the number of inches and parts of inches to which the compasses must be opened to describe the circles and parts of circles that are required.
Example. — Suppose that a wheel is to be made to contain thirty teeth, belonging to the series whose lowest pinion is eight teeth, and that the pitch of the teeth is to be 2^ in., proceed as follows:
Seek in column Vfor 30, the number of proposed te*eth, . and take from column 2 the numbers 4.783, which multiply by 2| in., the product will be 11.957, or nearly 12 in. For 1.783 X 2£ = 11.957 in. Open the compasses, therefore, to 12 in., and describe a circle, which will be the "pitch circle." Open the compasses to 2| in., which is the "pitch," and divide the circumference of the
pitch circle into the required number of teeth; from those divi- sions mark the thicknesses of the teeth.
Note. — A very good proportion between the thickness and the pitch of the teeth is from TWths to TVoths. In the next place search in column 3 of the same table, and in the same line with 30 teeth will be found the numlfcrs £.664:, which multiply by 2| in., the pro- duct will be 11.66, equal to llf in. For 4.664 X 2£ = 11.660 in. With the compasses opened to this dis- tance, and from tlie same center as the last, describe another cir- cle, which will be the paths of centers for the curves of the faces of the teeth. From column 4 similarly take the numbers 0.868, and multiply by 2| in. The pro- duct is 2.27, or rather more than 2\ in., to which distance the com- passes must be opened to describe the faces of the teeth.
In illustration, place one foot of the compasses, which has been opened to 2^ in., upon the circum- ference of the circle, called the paths of centers, recently de- scribed, in such manner that the other foot of the compasses touches one of the divisions of the teeth, marked upon the pitch circle. From such division de- scribe a curve upward, which will represent one side of the face of the tooth.. Care must be taken, however, when commencing, that the tooth you are about to draw, and one side of the face of which you are about striking, lies be- tween the two points.

OBSERVATIONS.
Having been much annoyed at our works at Derain, and at other places, with the frequent break- ages which occurred to the teeth of wheels, used there in our forges and mills, and also by the loss of time and the heavy expenses at- tendant on them, I was resolved, if possible, to rectify the error.
Fortunately, I had many years previously studied with much at- tention the geometrical and ma- thematical investigations of the celebrated Comas, Bryan Donkin, the well-known engineer of Lon- don, Prof. Willis of Oxford, and other eminent authorities on the subject. The theories of most of them, however, though admirable
as geometrical investigations, are not— if we except the treaties of Bryan Donkin and Prof. Willis — such as could be followed in prac- tice. And even these latter re- quired to be combined together, and modified by the experience which I had acquired by years of observation.
Eventually, after mature con- sideration, I was enabled to con- struct the "Table of the Teeth of Wheels," which I now give you. They have been used for years at our works with marked success, and with the satisfaction of know- ing that the teeth of the wheels which have been so formed work admirably together ; so much so, that a breakage from such a cause

is now of very rare occurrence — indeed, we may say, it is almost unknown to us. I must now re- quest your attention to the fol- lowing statements on the teeth of wheels:
In forming the teeth of wheels, although the driver wheel of nec- essity must act upon and propel the driver, yet the teeth of both wheels, to avoid breakages, must be considered as rolling the one upon the other, and their teeth must be formed accordingly. From the consideration of this essential quality, and the condi- tions to be fulfilled, the foregoing tables have been constructed. The calculations have been made on strictly mathematical princi- ples, notwithstanding which the tables are of easy application by the pattern-maker and the mill- wright.
Teeth marked out, and con- structed in conformity with these tables, possess many advantages:
1. There is an economy of time in designing the pattern.
2. The teeth work together with great accuracy.
3. Teeth so formed maintain their shape to the last; they do not wear away more at the roots proportionately than in the other parts of the teeth, as is but too frequently the case with teeth formed in the usual way.
4. The greatest possible amount
of strength is given to them at the roots ; therefore, by possessing a rolling motion, by wearing more uniformly, and by being stronger at the roots, the liability to break- age is reduced to a minimum.
5. All teeth of the same pitch, whatever the tliameters of their wheels, work accurately together, obviating thereby the necessity of having so many expensive sets of patterns, as we commonly see in large engineering and mill- wrighting establishments. Even in extreme cases, but three sets can possibly be needed. But, generally speaking, one set of patterns alone will be found am- ply sufficient for all practical pur- poses.
Notwithstanding these state- ments, the tables comprise the particulars for forming three sets of patterns. In one set the small- est pinion contains eight teeth, in another set the smallest pinion contains ten teeth, and in the third set the smallest pinion con- tains twelve teeth. From which- soever of the three sets, as com- prised in the tables, the patterns are formed, all wheels, whatever their diameters, belonging to that series of patterns, will work ac- curately together.

teeth, the roots of the teeth in wheels of large diameters are very spreading; which, however desirable in cases where great strength is required, may in the eyes of the millwright for other purposes appear objectionable, though all the wheels of the series work most accurately together. To obviate any objection of that nature — which is an objection simply of the eye and not of prac- tice— another series has been com- puted, wherein the smallest wheel is a pinion of twelve teeth. I re- peat, whichever is used, the wheels, whatever their diameters work together with equal accu- racy.
Previously to entering upon the tables, it may perhaps be as well to explain some of the technical terms that are employed : Radius is half the diameter of a circle or the extent to which a pair of com- passes must be opened to describe a circle around a given point. Radii is the plural of radius. "Pitch circle." — When a drawing, or the pattern of a wheel is to be made, the first operation is to de- scribe a circle, upon the circum- ference of which the distances the teeth are to be asunder must be marked, as also their thick- nesses. Such circle, called the "pitch circle," passes nearly mid- way between the roots and the tops of the teeth ; and when
wheels work well together, and their teeth are properly formed, the pitch circles of the wheels touch, but do not cut each other. The pitch circle is sometimes called the "primitive," and some- times the "proportional circle." The latter name is incorrect in its signification, and has produced numerous errors, not only in vari- ous rules and tables which have been given to the public, but, unfortunately, in wheels which have been constructed from those tables and rules in large establish- ments. The term supposes that the radii of wheels are directly proportional to the number of re- volutions those wheels are to make, the incorrectness of which may by known by simple inspec- tion of column 2 in the foregoing tables. That column, to the best of my recollection, was first cal- culated and given to the public by Mr. Bryan Donkin. The whole of the other calculations con- tained in the tables are the re- sults of my own labor.
"The pitch." — The distance in a straight line from center to center of each consecutive tooth, or from the side of one tooth to the same side of the next adjoining tooth, measured upon the pitch circle, is called the " pitch of the tooth." "The thickness of a tooth" is that part of the tooth which can be measured upon the pitch line.
382
Machinists and Blacksmiths'
"The face of a tooth" is that por- tion of the tooth which lies above the pitch circle. " The flank of a tooth" is that portion of the tooth which lies below the pitch circle, or within it. The space between tooth and tooth is sometimes called "the hollow." Besides the above terms, which are tolerably well known in the workshop, we make use of another, called the "paths of centers," which are circles concentric with the pitch circle. There are two of these paths to each wheel, one within, and the other without, the pitch circle. From the one without the pitch circle is described the flanks of the teeth, and from the one within, the "faces." These will be better understood after read- ing the examples.
The tables, as before stated, comprise calculations for forming three sets of patterns, which are all that can be required in prac- tice. By most engineers and mill- wrights but one set will be used. The calculations for each set are contained in six columns, marked from No. 1 to No. 6, consecutively. Column 1 exhibits the number of teeth which any given wheel is to have. Column 2, the radii of the pitch circles corresponding with those number of teeth. Column 3, the radii of the paths of cen- ters, from which are to be de- scribed the faces of the teeth.
Column 4, the radii by which the faces of the teeth are described. Column 5, the radii of the paths of centers, from which are to be described the flanks of the teeth. And column 6, the radii by which the flanks of the teeth are de- scribed. The five last columns are all expressed in terms of the pitch — in other words, the number of times the pitch is contained in each. Consequently, when the pitch is known in inches and parts, all that is required for the use of the tables is a proper observance of the following rule for the breadth of teeth: Let a=breadth of the teeth in a line parallel with the axis ; 6=thickness of the teeth measured on pitch circle ; s=en- tire height of the teeth from the root. The above dimensions be- ing expressed in centimeters, for teeth continously greased, and of which the velocity does not ex- ceed 1£ meters per second, a=4 times b. If it exceeds that speed a=5 times b. And if the teeth are exposed to water a=6 times b. s should at no time exceed 1£ times b. A centimeter is equal to .39371 English inch, or four- tenths of an inch nearly. And 1£ meters is equal to 59.0565 English inches, or a little more than 4 feet 11 inches.

ANNEALING.
•
The change produced by an- nealing is not well understood. Most of the malleable metals as- sume two distinct forms ; one crystalline, which is the result of slow cooling, and the other fibrous which is brought about by ham- mering or rolling. If hammered or rolled beyond a certain point, the metals become so hard that they cannot be bent without breaking. If annealed beyond a certain point, the metals be- come crystalline. Thus, zinc may be drawn into a very flexible and tenacious wire; but if kept in boiling water too long it resumes its original brittleness, and dis- plays a crystalline appearance when broken. The particles of the metal change their arrange- ment without altering their ex- ternal form, and this change may be brought about in various ways; thus, brass wire loses its tenacity by exposure to the fumes of an acid, and even by air acting on its surface in a damp atmosphere. Hence it is necessary to preserve wire, such as is used in the manu- facture of pins, in a dry air, or under the surface of water.

LIABILITY OF RAILROADS FOR FIRES.
A Pennsylvania farmer sued a railroad company for the loss of a barn by fire kindled by the sparks from a locomotive. In the lower court the jury awarded the farmer $2,300 damages. The railroad company appealed to a superior court. It was shown that the barn was some distance from the track of the railroad, and that the intervening space was occupied by abundance of dry grass and weeds, etc., by which the fire was communicated to the building. The court overruled the first deci- sion, on the ground that as no one is responsible for the accidents from remote, but only for those from immediate causes, the owner of the barn must bear the loss. "The sparks from the locomotive did not fire the barn, but the grass, and it was the grass which fired the barn." If a farmer should fell a tree or dump a rock on the brow of a bank, and the declivity of the bank should roll the tree or rock on to a railroad track, would he be held liable only for the remote cause of felling the tree or dumping the rock, and the declivity made answerable as the immediate cause of the obstruc- tion ? — Exchange.

THE TOOLS OF GREAT MEN.
It is not tools that make the workman, but the trained skill and perseverance of the man him- self. Indeed, it is proverbial that the bad workman never yet had a good tool. Some one asked Opie by what wonderful process he mixed his colors. "I mix them with my brains, sir," was the re- ply. It is the same with every workman who would excel. Fer- guson made marvelous things, such as his wooden clock, that accurately measured the hour — by means of a common pen knife — a tool in everybody's hands, but then everybody is not a Ferguson. A pan of water and two thermo- meters were the tools by which Dr. Black discovered latent heat, and a prism, a lens, and a sheet of pasteboard, enabled Newton to unfold the composition of light and the origin of color. An emi- nent foreign savant once called upon Dr. Wallaston and request- ed to be shown over his labora- tories in which science had been enriched by so many important discoveries, when the doctor took him into a little study, and point- ing to an old tea tray on the table containing a few watch glasses, test papers, a small balance and a blow-pipe, said, "There is all the laboratory I have !" Stothard learned the art of combining
colors by closely studying butter- flies' wings. He would often say that no one knew what he owed to these tiny insects. A burned stick and a barn door served Wilkie in lieu of a pencil and canvas. Bewick first practiced drawing on the cottage walls of his native village, which he cov- ered with his sketches in chalk ; and Benjamin West made his first brushes out of the cat's tail. Fer- guson laid down in the fields at night in a blanket, and made a map of the heavenly bodies by means of a thread with small beads on it, stretched between his eye and the stars. Franklin first robbed the thunder-cloud of its lightning by means of a kite made with two cross sticks and a hand- kerchief. Watt made his first model of the condensing steam engine out of an old anatomist's syringe, used to inject the arteries previous to dissection. Clifford worked his first problem in ma- thematics when a cobbler's ap- prentice, upon scraps of leather, which he beat smooth for the purpose; while Rittenhouse, the great astronomer, first calculated
eclipses on his plow.

THE PACTS ABOUT EBON.
There will be made (says the New York Tribune) this year in the United States about twenty- five hundred thousand tons of pig iron. In the year ended June 30 1872, there were imported into the United States iron and steel in various shapes which, if pro- duced here, would have required the making of fifteen hundred thousand tons of pig in addition to the two million and odd tons we actually did make. Now the change which protection is work- ing in the iron trade is simply this : that we are making more iron and importing less. Our ex- port trade in pig, bar, plate, sheet and railroad iron is comparatively nothing ; not the twentieth part of our imports of the same arti- cles. In cutlery and edge tools our exports are more consider- able, but still far less than the imports. This is a dull year. We are consuming much less iron than we were fifteen months ago. Yet still we are importing iron and steel at the rate of the equi- valent of three-quarters of a mil- lion tons of pig iron a year, while our furnaces are working nearly to their full capacity. These are the essential facts: what is the conclusion that we should draw from them?
The tariff should not be changed
for the present. The total value of the imports of iron and steel and manufactures thereof that entered into consumption in the United States was $21,922,127, or a little more than forty per cent. In August, 1872, the duties on all those articles were reduced ten per cent. There has been a great rise in the price of iron and steel since 1872; and, as the duties are mostly specific, the revenue for the current year will fall below thirty-five per cent, of the value of the goods, reckoned in gold at the foreign ports where they are shipped. We need revenue and we need protection. It is folly to suppose that the price of coal in England will not be considerably reduced within the next twelve months. When production is again carried on in England under settled conditions of the coal and labor markets it will be time to take into consideration another reduction of ten per cent, in our duties on iron and steel. Before we venture upon that, the expen- ditures of the government should be cut down, and further progress should be made toward specie payments.
Well enough should be let alone. Nothing is more injurious to the growth of manufactures than fre- qnent changes in the tariff. The prices of iron and steel are now made, more than ever before, by

the competition of American pro- ducers. If the business is more remunerative than other occupa- tions capital will be attracted to it, the supply will be increased, and prices will fall. We have since 1851 multiplied by twenty our annual production of railroad iron. In the same period our con- sumption of foreign rails has only doubled. We think that the pro- gress thus made should be con- solidated before we throw wide open our ports to the greater capital, cheaper labor, and most desperate competition of the Eng- lish manufacturer. Even if we accept the free trade hypothesis, that we have built our house in the way it ought not to be built, are we to tear the house down, now that it is nearly finished, in order to construct it on correct principles? At a proper time, which cannot be distant, we shall advocate a great reduction in the duties on iron, but at present such a step would be most ill-advised.
CAPITAL VS. LABOE.
The iron masters of England are organizing to contend with the Trades' Unions whenever strikes are prosecuted. A correspondent of the New York Times says of it : " But there is something going on at this moment in Great Britain which may be fraught with —
goodness knows what ! — both as to this international iron^_ ques- tion,' and every other question. An organization has been formed and is now being perfected, of by far the most gigantic character the world has ever known. It is called the National Federation of Employers. It embraces all the trades and manufactures, is in- tended once and forever to eradi- cate the principle of strikes, and already numbers among its mem- bers firms representing over £1,000,000,000 capital. It is to be among employers what Trades' Unions are among the employed. If a general strike in any branch of manufacture occurs, the Fed- eration is to assist with money and influence the involved em- ployers in resisting the demands of the strikers. Here is an open declaration of war against the Trades' Unions. When the battle between the Federation and the Trades' Unions begins in earnest, some one will get hurt. Which- ever way the fight terminates, America must benefit by it. If the employers win, we may look for a heavy emigration of Great Britain's most skilled laborer's. If the Trades' Unions gain the day, British labor will and must rise to the level of American
labor.

CO-OPERATION AMONG THE FREEDMEN.
The colored people of Calleton county, S. 0., are trying the ex- periment of co-operation on a large scale. Parties of from ten to fifty form a society, elect offi- cers, and adopt by-laws. They have regular meetings at which the officers report, and a specified amount is paid into the treasury by each member. A suitable plantation is selected and pur- chased, a part of the money be- ing paid down, and the rest within one, two or three years. The land is equally distributed by the officers elected for that purpose among the members of the so- ciety. Each is free to work as suits him, and can dispose of his crop as he deems proper. The only requirements are good be- havior and prompt payment of dues, which are usually light. Any one wilfully failing to meet his dues, or convicted of dishon- esty, has all amounts previously paid in by him refunded, and is then invited to leave the planta- tion. If any one wishes to with- draw, he is returned his share of the purchase money, and com- pensated for all permanent im- provements. No new member is admitted without common con- sent. All the sick are cared for by the society, it being the duty of the officers to look after cases
of illness. If an unusually large sum of money is necessary to re- lieve the sick, a special meeting is held to raise it. Certain officers are designated to settle all dis- putes by amicable arrangement, and they seldom fail, thus avoid- ing that petty litigation which is the bane of the colored people. The societies are formed chiefly of those who work for hire, fifty cents per day being the ordinary due. Some of the societies have been in operation three or four years, and paid for their land. There have been failures for a time, owing to incompetent and unfaithful officers; but these be- ing removed, things have worked well again. The societies are lo- cated principally in the low coun- try east of the Savannah and Charleston railroad. While there are colored men who by single effort have accumulated fortunes within the past six or eight years, the higher average of success and prosperity is with those in the societies. The reason is, that, by securing a whole plantation, they obtain sufficient good land for their purchasers, while he who buys for himself generally gets a few acres, barely enough for a
poor subsistence.

THE NATION'S FORESTS.
In an article under this caption the New York Times says : To as- certain by actual scientific ob- servations and measurements the influence of forests on the annual rain fall, moisture of the air and ground, and on the climate gen- erally, the Bavarian government established at different elevations and in different parls of the king- dom seven stations, at each of which daily observations were made at two different points, one situated in the middle of a large open field, the other in the middle of a large forest. The results of these observations, according to Dr. Ebermeyer's report, agree with the observations and opin- ions given by Humboldt, De Saussure, Herschel, and other na- tural philosophers in regard to the great influence of forests on the climate, relative moisture, fertility and healthiness of a coun- try, and are confirmed, besides many other facts, by the present physical condition of the Mediter- ranean shores, which, since the Alps, Appenines, and Pyrenees were deprived of their forests, have lost the pristine verdure and fertility so glowingly described by ancient geographers and his- torians. Rivers famous in song and story have shrunk to insigni- ficant streamlets, subject to sud-
den rises and overflows, inundat- ing and covering with gravel and sand the former fertile valleys. The destruction of the forests of the Vosges and Oevinnes sensibly deteriorated the famous fertility of Elsass and the rich valley of the Rhone. The same discoveries, although in a lesser degree, we are now making in various parts of the United States. A London contemporary, in commenting upon the tremendous ravages of the settler's ax, and the still more destructive one of the lumbermen in America, compares this whole- sale stripping of the Republic's soil of its timber to Delilah's rob- bing Samson of the secret of his strength; and, if this process of deforesting and disrobing of the earth continues at its present accelerated rates a quarter of a century longer,what, asks another writer, is to hinder the land from entering upon a long era of physi- cal degeneracy and climate de- terioration that must sap its in- dustrial and even its intellectual energies, and reduce its fair and salubrious bosom to the aspect of a South American Llano, 'dead and rigid like the stony crust of a desolated planet!' as Humboldt poetically expresses it. Unless there can be excited a national interest in this subject, it must become evident to the most un- observant, as it has long been to

Brown's Rotary Sewing Machine Company, which was organized a few weeks ago in Indianapolis, Ind., with a capital of $500,000, intends to put up its buildings at1 once, and to have its machines in the market within six months. They will employ at leasts one thousand hands when in full blast.
The Montreal Witness says that the largest piece of forging ever made in the Dominion has just been turned out of the Molsic Iron Company's forge at Brew- ster's bridge, in that city. It is a main shaft intended for the steamer Saguena, to replace the one broken some time ago. It measures twenty-five feet three inches in length, thirteen and a half inches average diameter and weighs over seven tons. It was made of Molsic iron, and is pro- nounced by several Canadian en- gineers, who have examined it, to be as good as anything of the kind made in England or the United States, from which coun- tries, previously, such articles were obtained.
The St. Louis Railway Register, in a notice of the Fulton Boiler and Sheet Iron Works of that city says: "One remarkable feature of this establishment is its tem- perance.

Severely Scalded.
The Knoxville Chronicle of a recent date contains the following: Yesterday morning, Mr. Mosely, foreman of the railroad machine shop, made a narrow escape from being scalded to death. He was under an engine making some repairs, when it became necessary to reduce amount of steam in the boiler, there being a head of a hundred pounds on at the time. A boy employed at the shop was ordered to let the steam off twenty pounds, and not being aware of Mr. Mosely's presence under the engine, he drew the plug from the "blow off cock," letting the steam right into his face and neck, scalding them pretty badly. Mr. Mosely, with remarkable presence of mind, wheeled around instantly, exposing such parts of his body to the steam as were pro- tected by thick clothing, thus destroying to a great extent the effect of the steam, and then made his exit from his perilous position, but having to endure the terrible heat until he had passed entirely from under the engine. The workmen at the shop rushed to the scene — without any hope, however, of getting him out alive, as it was impossible to replace the plug — aad were not a little surprised and over- joyed when Mr. Mosely's form emerged from the scalding spray. The proper remedies were at once applied, and at last accounts Mr. Mosely was doing well.

Important Business Change.
The following notice, which we take from the Decatur (Illinois) Daily Republican, will be read with pleasure by hundreds of our subscribers, who will join us in wishing the new firm the largest measure of success:
James Milliken, Esq., has disposed of his interest in the Central Iron Works and Foundry, that have been for several years run by Burroughs & Co., C. C. Burroughs, Esq., retaining his interest in the concern. The pur- chasers of Mr. Millikin's interest are Edward Towhill, C. F. Hirt, Thomas Paradine, Chas. Gradwell, William J. Barrett and John M. Flood — and the price paid is $35,000.
These men are experienced mechanics, and with the exception of Mr. Flood, are new- comers among us, and hail from Erie Penn- sylvania. Messrs. Towhill, Hirt, Paradine and Gradwell are machinists, Mr. Barrett is a blacksmith, and Mr. Flood is a practical moulder. As will appear from what follows these gentlemen have all occupied important and responsible positions in their respective trades.
Mr. Towhill has filled the very difficult and responsible position of Foreman in the Erie and Pitts Locomotive Works, located at Erie, Pa., for the term of three years.
Mr. Hirt was for two years Foreman in the Presque Isle Iron Works, at Erie, Pa., it being one of the largest saw-mill and gearing manufactories in the country.
Messrs. Paradine and Gradwell are ex- perienced engine builders, having been em- ployd for several years in the largest engine works in the country.
Mr. Barrett was assistant Foreman in the extensive forging shop of the Pennsylvania Railroad Co., at Erie, Pa.
Mr. Flood who is already known to our people, has held the position of Foreman in the moulding department of Burroughs and Co.'s Foundry, for the past four years, and for seven years prior to coming to this city was Foreman in Zimmerman's Foundry, St. Louis, Mo.
These gentlemen are all to be actively em- ployed as workmen in the establishment, Mr. Towhill being Superintendent.
The firm thus constituted is to be known as the Union Iron Works, and is officered as follows :
President — C. C. Burroughs;
Vice President — Thomas Paradine;
Secretary — C. F. Hirt;
Treasurer — W. J. Barrett.
We regard this as one of the most im- portant changes that has occurred in connec- tion with any business establishment in our city for some time past. It is important to us as a community because it brings to our midst
five active business men, in the prime of life, four of whom have families. The positions they have respectively occupied is a guarantee that they are reliable, trustworthy men, and such men are always a valuable accession to any community.
But not only is this new order of things a matter of importance to us as a community, but it is particularly so to the establishment with which these gentlemen are identified. Being at the same time proprietors and work- men in the concern, there will be a double motive to bring their establishment to the highest standard of excellence. While, there- fore, the "Central Iron Works," under the management of Burroughs & Co., has for several years been an establishment of which Decatur was justly proud, it is but reasonable to expect the "Union Iron Works," with its corps of competent and experienced workmen, will greatly advance, both in the extent and quality of its work, upon anything ever at- tained by the old establishment.
Mr. Burroughs, the president of the new firm, has been prominently connected with the business of Decatur for the past sixteen years, half of which time he has been the active head of the establishment which has been re- organized with himself as the president. To say one word in his praise would be superflu- ous. Suffice it to say that his high standing as an honorable, energetic business man, emi- nently fits him for the part he is to take in the business of the new firm. In addition to his duties as president he is to attend to the out- side business, such as buying material, con- tracting for work, and devising and putting into execution, plans to extend the business of his concern.
And now in conclusion we would say to all our readers who maybe wanting anything that comes in the line of the "Union Iron Works," they can feel assured that this institution will give them as good work, and upon as reason- able terms as they can get at any establish- ment of the kind in this or any other state. Knitting* Needles* There is a needle factory on Pigeon Creek, at Lawrence ville, Pa., where knitting needles of nearly five hundred different kinds are made. They are used in mills for the manu- facture of stockings, drawers, shirts, caps, shawls and other knitted goods. The work is all done in one forty by sixty feet room. The wire used is of a rather soft steel, imported from England. Some of the needles are straight, others curved, others still hooked, with many variations in shape and size. From two to twelve thousand needles are manu- factured in a week, the number depending upon the kind and the demand for them.

Steam Locomotives without Fire.
A fireless locomotive has lately been tried in Chicago. The Tribune of that city says: "In front of the cars was the motive power, con- tained in a small, compact, and neat loco- motive, manipulated by an engineer. This was the fireless locomotive. It consisted of a boiler, eight feet long by three feet in di- ameter, and the usual machinery on a small scale. There was no fuel, no fire, no fireman. The steam was supplied for the round trip of six miles before starting. At the depot was a supply boiler, sixteen feet by three feet, in which steam was generated until 200 pounds pressure was indicated by the steam gauge. The locomotive boiler was three fourths full of cold water. Instead of boiling this by means of a fire and raising the pressure to a required hight, the heat was introduced from the supply boiler through an iron tube. The iron tube was connected with the locomotive boiler, the latter running under the water along the bottom of the boiler and letting out the superheated steam, as it was freed from the supply boiler, into the locomotive boiler. This steam rising through the cold water, per- meated it, and quickly raised its temperature to 170 degrees. With this supply of steam the locomotive started, drawing a heavy four horse car over the three miles, to 35th street in ten minutes. The amount of steam consumed was 80 pounds, the locomotive starting back with 90 pounds remaining. When the start- ing point was reached, there was 57 pounds of steam in the boiler, the pressure being re- duced only 33 pounds in the return trip, which was down a grade. It must be borne in mind that there was a large car, heavily laden, making eighteen miles an hour. The ex- periment proved conclusively that, as a sub- stitute for dummy engines, the fireless loco- motive is, beyond question, a success. There is no fire or fireman required, very little steam escapes, and the locomotive, not being one half the size of the clumsy dummy engine does not frighten horses and endanger the public safety.

Telegraphic Invention.
A young man in California claimed to have invented an apparatus by which telegraph- ic dispatches could be received and sent on a train of cars in motion. Mr. Almy, an inven- tor residing in St. Louis, states that he also has filed a caveat for another device that will se- cure this end, which is so desirable as a pre- ventive for railroad accidents. The condition of Mr. Almy's invention is that the rails shall be steel. These he would charge from the batteries at the stations, and then make them perform the part of telegraph wires. As the stationary batteries might not be sufficient for this purpose, he would save and utilize the electricity generated by the friction of the wheels upon steel rails, by conducting it to a receiver. Thus every train, it is claimed, would be a telegraph office, and though there should be no operator aboard, a code of sig- nals could be easily constructed that would answer all the necessary purposes.
Incrustation of Water Pipes.
The Boston fire insurance companies are now calling attention to the condition of the water pipes in that city. It seems that the water supply is greatly diminished by the incrustation formed on the inside of the iron pipes by. the action of the water, so that a three inch pipe that has been laid ten years becomes reduced to two inches, those of four inches to three, and the six inch mains re - duced to five and four inches. A pipe was re- cently taken up in Howard street through which one could not see, though water flowed slowly: and a pipe of three inch bore was taken up in Beacon street, filled up solid with rust. Here is a chance, says the Boston Ad- vertiser, for an inventor to discover some coating to render iron pipes proof against the action of water. In the suburbs cement pipes are used, but it said that they are hardly strong enough to bear the pressure of the Cochituate water. — New York Times. Volume XI.

JEMMY, THE LIGHTHOUSE BOY.
[For the Machinists and Blacksmiths' Journal.]
Upon the coast of Maine, where billows dash
and roar, In view of ever-changing sea, and grand, ma- jestic shore, A lighthouse stood on rocky pier — a home 'mid
the rolling deep- Where lashed in fury by the storm gigantic billows sweep.
But firm it stood upon the rock, amid the raging gales
Breasting the waves, and by its light warning approaching sails;
There lived Jemmy, the keeper's son, his cher- ished, darling boy,
Comfort of that secluded home, its happiness and joy.
Early in spring, one beauteous morn, while each
drop sparkled in the sun, The keeper took his fishing boat and left his
humble home; But evening came and clouds appeared and in
blackness robed the sky, The winds roared boisterously round the tower,
and still no keeper nigh !
Anxious and pale the mother sat, with wasted,
feeble frame, She could not light the tower lamps she was too
weak and lame; So there she sat while Jemmy gazed upon the
beating storm And heard the sleet dash 'gainst the tower, and
still no light to alarm !
Soon Jemmy spoke : " What shall we do to scale
the tower so steep, And fire the lamps, send forth the rays, and
illume the rolling deep? Father can't find his way again unless the lamps
we light, While many sailors may be lost out in the storm
to-night."
"I don't know what to say or do, my child," the
mother spake, "I am too feeble, you too young, this task to
undertake." "I'll light them, ma; do let me try, they must be
lit to-night." "Go, then, my son," the mother said, yet feared
him from her sight.
Then Jemmy climbed the tower high until he reached the top,
But found he could not reach the wicks without
an underprop; But by a table's kindly aid, and several broken
sticks, At last he found that, on tip -toe, he could just
reach the wicks.
Then soon the light went streaming forth over
the dark, dark sea, While Jemmy danced upon the floor so great his
extacy; But soon he faced the boisterous gale, in spite of
the dashing spray, And called, though shivering in the blast, "Dear
father steer this way."
Again, and yet again, he called aloud, outside
the tower, "Steer this way, father, steer this way," rang
out with all his power; And, strange to say, the father heard way out on
the foaming sea, And soon was sheltered from the blasts and the
storm's inclemency.
"Jemmy, my boy," the father cried, clasping
him in eager embrace, "But for you I would not reach home to-night,' '
and he showered kisses on his face ; They then knelt down, with tearful eyes, and
their grateful voices raise, And for the favors shown that night to God they
gave the praise.
And now, to close this simple rhyme, Jemmy has passed away,
And gloomy is that little home amid the dash- ing spray;
Father and mother wait and watch, and soon they hope with joy,
Again to clasp their darling son "Jemmy, the lighthouse boy!"

Demagogues and. the Press.
The individual, who, examining into the present relations of capital and labor, and ascertaining without a doubt that, of all the products of labor and capital, labor receives but a bare subsistance; whilst capital, through several causes, takes to itself all above labor's mere daily subsistence, — and such individual being blessed with the ability and the oppor- tunity to expose and denounce the system that permits such injustice, is at once made the tar- get lor all the venom of the independent press. "Demagogue," "agitator," "communist," "ag- rarian," etc., are hurled at him, with a whole vocabulary of adjectives. He may advance statistics to prove his position a correct one: his figures are answered by vituperation. He may advance arguments based upon the wri- tings of the best thinkers on jolitical economy: he will be answered with slurs on his want of education. He may advocate combinatian among woikingmen as a stepping stone to re- dress: he is accused of importing foreign in- stitutions; and soon with every point advanced. Argument is not answered by argument. An appeal to the reason is answered by an ap- peal to the passions. Labor reformers claim that labor does not receive its just reward: that claim has never been denied, — the proof are so clear that argument thereon is out of ques- tion; and yet every effort to secure to labor its just reward is howled down by the "press." We do not claim that labor in its efforts is al- ways right. We know by experience that broodii g over its wrongs and seeing no honor- able way to obtain redress, it has been lit- erally driven into excesses which its best friends cannot help but deprecate; but that it has wrongs to redress, and that they must be redressed, may now be considered a certainty: for there has awakened a spirit of inquiry among woikingmen that will never be quieted or howled down until redress is beyond a ques- tion. If woikingmen devoted the same time and money to the labor press of the country that they now do the political press, — if they studied their own interests to one-half the extent that they study the interest of party politics, a few years would find them prepared to demand and exact justice from those who now cajole them into the belief that the present system, which gives every advantage to capital at labor's expense, is the only true system of national prospeiity. Some of our so-called writers on political economy, to prove the general prosperity of the country, to the immense addition to the wealth thereof, as shown by the late census; but they fail to show that one-half the immense wealth is owned by five per cent, of the people, and they dare not analyze the condition of those whose muscles have made all the wealth. Discussion is not what they want; they dread it as men do
pestilence. But all their efforts will only put off the day of labor's triumph; not a triumph over eapital, but a triumph over its own igno- rance: for labor has only to know right from wrong, and then will that right take the place of wrong, and it is done.
The press of the country, which should be the great popular teacher, has, through the moneyed influence of those who desire the ex- isting state of affairs to continue, become not only the apologist but the advocate of the present system, and thereby causes that di- vision between the thinking and unthinking portions of labor, to which may be ascribed all its ills. But a change is coming. The press sees it; they are more than disposed to tem- porize and conciliate. A portion of it now ad- vocates certain concessions, not because the claim of labor is just— they dare not put it on that ground — but it is endeavoring to show its masters that small concessions must be made or full justice will be exacted. While it is thus urging capital, it never lets up on its fran- tic yells about "demagogues," "communists," etc., as it is pleased to call those called by their fellows to take the lead in this war against ignorance. — Exchange.
The Power of a Locomotive.
When the first locomotive was patented, driving only one car, if lightly loaded, it did very well; but when the load it diew was heavier than its own weight, its wheels would not bite, that is, they would turn round and round without advancing. It seemed at first impossible to make a less weight move a greater on an up grade; and for some years no one invented an engine able to draw three times its own weight. At the present time, however, locomotives sweep along with trains more ponderous by fifteen or twenty times than they are themselves. One means of gaining this vast increase of power for the locomotive, was by dividing the load. It was found, that an engine powerless to stir five times its weight of freight when concentrated in one car, could readily draw it when dis- tributed in a dozen cars loosely shackled to- gether. It was heavier than each single car; and it had overcome, the inertia of each one a moment before it encountered the inertia of another. It was thus more than a match for each car taken singly; and pulling them suc- cessively, it drew after it a train as long as a comet, and the farther it ran the more strength it had to run farther. Here was the story of little David over again. Ordinarily, the strip- ling's weight, as he told Goliah, was one hund- red and twenty, but whanever hegot mad he weighed a ton. Moreover, the engine forced the momentum accquired by every car it had started, to swell its own potency in overcoming the resistance of all that remained motionless.

Iron and Coal Resources of the Keystone State.
The New York Times says: The great de- gree of public attention which has lately been called to coal and iron has concentrated an unusual degree of interest upon Pennsylvania. We propose in this article to take a brief general view of the natural and acquired re- sources of that State.
The estimated value of all the real and per- sonal property of Pennsylvania was, according to the census of 1870, $3,808,240,112. That of the State of New York was $6,500,841,264. The same valuation assigns to this city $3,484,268,700, and to Philadelphia $1,206,- 254,758. This leaves $3,016,572,564 for this State outside of New York City, and $2,602- 085,355 for Pennsylvania outside of Philadel- phia. The valuation to which we are here re- ferring, it may be well to mention, is not merely the official assessment for purposes of taxation, but the result of calculation made from such assessments and various other sources of information.
It is our purpose at present to speak partic- ularly of Pennsylvania outside of Philadel- phia; and perhaps the most clear and exact idea we can give of the present wealth of that portion of the State is to say that, according to the figures we have quoted, it is slightly — four per cent — greater in proportion to the popula- tion than that of our own State outside of this city. This difference is so slight that it would be in itself scarcely worthy of remark. But the wealth of this State outside of the metropolis and its immediate neighborhood is almost all of such a nature that little more can, on an average, be anticipated than a fair and steady advance from year to year. That of Pennsylvania may increase within a very few years to an extent to which it is difficult to assign any definite limits. From present appearances the value of iron and coal resour- ces of the State twenty, or even ten years, hence seems not unlikly to attain proprotions the mere prediction of which, but a short time since, would have been regarded as utterly wild and absurd. These interests are con- sidered, not merely by visionary enthusiasts or persons who, for their circumstances, may be supposed to be inclined to the most favorable views, but by great numbers of thoughtful and unprejudiced men, to be still in infancy. To whatsize these uncommonly promising infants are likely eventually to grow is a point upon which we do not venture to express our opinion. The prospects of their developement, so far as can be calculated, are just now cer- tainly of a most promising description.
The coal and iron mines of Pennsylvania would be of far less value than they are, were i not for the great agricultural resources of the State. A good and cheap supply of pro-
visions for the workingmen and their families is obviously an exceedingly important point in connection with the rate of wages, and the facility of obtaining labor. What the full ag- ricultural capacity of the State is, it is im- possible to say. The high cultivation and great productiveness of some of the older portions are well known. The farmers of Lancaster county have long had an almost national reputation. But there are many counties of great natural fertility in the north- ern and western parts of the State, only a small proportion of the area of which has yet been cleared of forests. This is especially true of what is known as the "northern tier" of counties. Indeed, it may be doubted whether, taken as a whole, the northern half of the State is much inferior in agricultural capacity to the southern half. Some of it, indeed, is poor land, and besides this, there is a good deal composed of hills too steep for plowing; but the amount precluded from cul- tivation by either of these causes is far less than is supposed. Many of the counties which are now scarcely settled would, if properly im- proved, support a very large farming popula- tion, and there can be little question that they will do so in the course of, at the most, the next twenty or twenty-five years.
In one kind of natural wealth Pennsylvania is altogether inferior to New York. Its extent of navigable waters bears no comparison with ours. Before the time of railroads this was a most serious disadvantage. What has been done since that time to obviate the defi- ciency is so well known that it need scarcely be mentioned. The Pennsylvanians are often looked upon as rather a slow moving and un- enterprising people. Their preformances in the master of railroads have certainly been a somewhat singular way of manifesting their trait of character.
The importanae of the resources of Penn- sylvania to the city of New York can hardly be overestimated. The waters in our vicinity are the nearest points of tide water to a con- siderable part of the anthracite regions. And if the anticipations which now seem not unrea- sonable, in regard to American iron, shall be fulfilled, the value of the products of that State to our commercial and manufacturing interests, great as it is now, must almost im- measurably increase. We are glad that our business men are giving so much thought to this whole subject. The amount of attention which they are bestowing upon it is none too great. On the contrary, it is, we think, in many respects, by no means equal to what its magnitude and importance demand. «> > <«

A New Method of Making Iron.
A new method of making wrought iron direct from the ore is now practiced in South Staffordshire, which is thus described: The inventors take the ore, grind it to powder, and mix with it powdered lime, together with pow- dered pitch or tar. "When pitch is used, a little water is all that is needed to produce a mixture having much the appearance of dark mortar. In this shape the preparation is spread on the floor of a close kiln, and treated pretty much like patent fuel. Here the mois- ture evaporates, but no portion of the metal- producing ingredients is lost. In a few hours the kiln has a surface of metal coke usually four, and, if necessary, eight inches, thick. This is broken up into sizes adaptable to a heating furnace of the ordinary iron works class, where it is submitted to fii e for half an hour at the utmost. In that time it is ready for the helve or squeezers, which it leaves a capital bloom, producing in the rolls a bar of half-manufactured iron, known, under the old principle, as a puddled bar.
Thus the use of the blast furnace has been altogether avoided, and the work of converting the product of the blast furnace into partially manufactured iron, which has heretofore re- quired the exercise of a large amount of troublesome skilled labor, has been effected by an operator who needs very little practice to make him efficient. The other stages through which iron has to pass in order to the completing of the bar, or sheet, as the case may be, are the same as in the old process. The inventors, who are Messrs. Gerhard and Caddick, claim that they require only two tons of coal to make one ton of finished iron from the ore; that they can make German steel as cheaply as cast iron, and that they can manu- facture cast iron equal in purity to charcoal iron without the use of charcoal, and they state that they have offers for all the finished iron they can make. The offers are, they ex- plain, at prices which would leave a splendid margin of profit. The inventors are taking steps to form a company. If all that they claim to be able to do is practicable, a sim- plicity has been attained in the making of iron which should go far to reduce its price in those smaller sizes and shapes which are most of all applicable to the business of the general iron merchants.

Lately a discovery was made in California of a third grove of big trees as remarkable for their gigantic proportions as those of the Calaveras or Mariposa groves, and in a local- ity easy of approach. "What adds to the value of this discovery is the fact that it is on the direct route to the Yosemite Valley, and tourists can take the grove in their route with- out extra cost or inconvenience.
Joseph Arch.
The following history is given of how Joseph Arch, the great agricultural labor reformer, first attracted attention in England: A couple of laborers knocked at Arch's cottage door in Barford one evening. Mrs. Arch answered the summons, and saw two sturdy bread- winners from a neighboring village. " We want thy man, Joe; is e at whoam?" "What's wantin', lads?" "Why, we want to talk to 'im about formin' a Union. Other trades 'ave a Union, an' we doant see why we shouldn't 'ave one; it's time we did summat." " You form a Union? Why, you aint got spirit enough, my lads, for no such thing." " Yes we 'ave, if Joe will only lead us." And it came to pass that Joe consented to lead them, and before the men left his cottage that night he had pledged them to address a gathering of laborers at Wellsborne the following week. The intelligence that Arch would have some- thing to say to the poor folk spread rapidly. It was the talk of the cottagers for miles around. " Whoy, lad, thee 'as 'eard as Joe Arch is goin' to preach to us?" "Noa! be 'e? Dang it, Joe knows a good bit, an' 'e's not stuck up wi' 'is learnin'. Awl go with thee an' 'ear 'im." Arch expected to talk to a small gathering in a little room in the village inn. To his astonishment he found upon reaching Wellsborne an out-door gathering of some fifteen hundred laborers, with a sprink- ling of farmers and esquires. A pig-killing board was brought out. Joe mounted it and began his speech. An enemy sent to the gas works and the lamps on the street were extin- guished. The laborers procured candles and the meeting was continued. The address made by Arch on that occasion was magical in its effect. The Union which he advocated now numbers 100,000 members.
Mr. A. T. Hay, of Burlington, Iowa, has written a letter to James H. McCord, United States Boiler Inspector at St. Louis, in which he takes the ground that boiler explosions are in the main the product of forces generated by heat from the effete matter in foul water. He thinks that when the potent forces known to exist in foul water are better understood — that is, when every practical engineer realizes that foul water possesses physical forces absolute- ly dangerous and beyond his control, and that, too, at such temperature and under such pressure as render clean water perfectly safe, none of the devices now in use will command any serious attention; while pure water will act the same every time under like thermic conditions, and may be set down as absolutely safe, with ordinary care, as a motive power.

Enthusiasm.
Susquehanna Depot, Sept. 11, 1873.
Mr. Editor — It seems the few remarks I made on Bro. Lawlers letter has roused his ire, which finds vent in a complication of words that Webster's Unabridged could hardly make strong enough to denounce the poor spouters whom he advises to qualify their en- thusiasm, but gives no point at which to stop. He does not tell us how many members we can propose before laying on our oars, or whether a member is permitted to organize one, two or ten Unions before goiDg beyond the line. On reading the elaborate and well- written article, a person might doubt the fact of its being extempore but for the reckless way he piles up the facts, seemii gly uncon- scious that the majority were like Dan Pun- denson's patent double-ended gun, in being certain destruction to the man who sets them off. I will look at the two points that he em- phasizes most, and call his attention to the absurdity of advancing as arguments against enthusiasm the work of the strongest body of recognized enthusiasts in the world — the Jesuits — to become one of which a man must of a necessity be a perfect zealot; and the words of Demosthenes, who thought no sacri- fice too great if in the end he ; ccomplished the object of his early ambition — to be perfect in creating enthusiasm. Strange that such a man should prefer silver to gold; strange that he should prefer living forever as the greatest orator that ever spouted to going to an un- known grave, as many a harder working man has done. I might go over all his points in the same manner, but will content myself by taking an extract from each of his letters Place them side by side and let them speak for themse' ves. In the first place is "I never knew an enthusiast but what was behind in action," in the second and qualified letter appears "To a certain extent I am an enthusiast." James is this inconsistency the effect of enthusiasm, or what?
Begging Bro. Lawler not to confound the enthusiasm I defend with that sometimes pro- duced by local option in Renovo, I still remain his enthusiastic brother,

The Sewing machine.
Cleveland, 0., Sept. 24, 1873. Mr. Editor — The following communica- tion, which I find in the Geauga (Ohio) Re- publican, I think ought to find a place in your valuable periodical. It is not at all improb- able that some one among the many intelli- gent readers of the Journal will develop "sufficient inventive genius" to attain the ob- ject desired. Yours, ***
IS THE SEWING MACHINE A BLESSING?
This is emphatically an age of inventions. In every department of our varied activities, inventive genius finds ample scope for its multitudinous powers. Everything that seems to facilitate the manual labor required in our every-day affairs, is very likely to be hailed as a harbinger of good to the human race. Now, while I would not decry any genuine improvement, yet there is usually two sides to every important problem. . But it is not my purpose to go into any discussion of the pros and cons in regard to any of the great inven- tions of the age. And, as regards the sewing machine and its uses I only wish to refer to a single point, and that more for the purpose of asking if some one has not sufficient inventive genius to surmonnt what seems to me the great objection to the sewing machines as at present constructed. Every person who has had any considerable experience in runn'ng a machine is aware of the terrible strain upon some of the muscles, but more especially upon the sciatic nerve, and that no woman can run a machine constantly for any great length of time without seriously impairing her health, and eventually undermining her constitution. The great difficulty unquestionably arises from the unnatural heel-and-toe motion in working the treadle. The practical question I wish to suggest is, whether there is not some way in which this great difficulty may be over- come. Whoever will invent a perfect treadle for sewing machines may consider his fortune guaranteed. Inquirer.

Narrow-Gauge Railways.
The difference between the cost of narrow- gauge railroads and ordinary four feet eight and a half inch gauge is rather more than most people imagine — that is, if we are to take the word of a writer in the Financier. There are now fifteen narrow-gauge railroads in operation in the United States, ha\ing seven hundred miles of track, and there are no less than twenty organizations and twelve hundred and filty mi'es under process of construction. The roads have been planned and constructed in the past two years. The cost through a level country is about $10,(100 a mile, includ- ing equipment of rolling stock, while the broad gauge costs from $35,000 to $40,000 per mile.

Milwaukee, Wis., Sept. 28, 1873. For the first time, since the organization of No. 2 of Wis., death has laid its cold hand upon one of our brothers, Christian Krue- ger, who came to us with a clear membership card from No. 2 of New York at the beginning of the month of June; though only a week after depositing his card with us, he was taken down by sickness and had to suffer a great deal until it pleased the Lord our God, to de- liver him from hi3 earthly troubles the first day of September. He spoke in thankful terms of the prompt payments of sick benefits, without them he would have been very badly off for the neccessaries of life. The evening before his death, he spoke to one of his friends about the Life Insurance of our organization, what a noble institution it was, and the desti- tute condition of his family after his death on account of him not joining this department when in good health. Here we wish to recom- mend to the readers of the Journal the short patent sermon of Brother A. Dow, published in the Journal for September. There was some- thing done by us in paying the funeral expen- ses, but that does not cover the present de- mands of the destitute family. Short were our acquaintance with the deceased brother, but he left the impression on all those who conversed with him that he was a noble char- acter.
In memory of him the charter of our Union is draped in mourning for thirty days.
