From the Mines to You take the crude metals as they come from the mines, alloy them in our own works, cast into decorati’ve shapes, or roll them into plates and draw into rods, tubes or mouldings, all in our own mills; then turn into finished products ready for use. We employ in every department the most skillful men that a liberal wage scale will obtain and turn out the best these men can produce, but artistic ability is no excuse for laziness in our factories. By watching expenses and keep- ing our plant equipped with the latest improvements in labor-saving machinery, at same time reaching direct ** from the mines to you," we are enabled to supply as fine bronze work as is executed in this country at more favorable prices than most other concerns.

RULE : To find thp weight of bronze or brass plates compute square inches, multiplying length by widtli. then divide the product by tlie number of square inches contained in one pound of the thickness spec i lied. EXAMPLE : A sliect i-i6 in. thick (Xo. 14 gauge) 47’- in. long by 10 in. wide contains 475 square inches. We hnd by the table above that Xo. 14 gauge bronze sheet requires 50 square inches to the pound, therefore we divide 475 by 50, which gives us the weight, 9?’ lbs.

We believe in the power of price: whether the purchaser seeks a work of art or an every-day necessity, he has the same wish to obtain ** his money's worth." The man or the corporation that devises the means of pro- ducing any article of utility for less cost than before, is to that extent a contributor to the public good. Competition strengthens the desire for processes that economize, and is as desirable in work essentially artistic as any other kind, it devolving on the manufacturer to employ men of proper ability and organize them so that the efforts of each man may, as far as possible, be along the line of his special qualifications.

RONZE, as an architectural enrichment, gives results hardly obtainable at same cost in any other material. What is more distinctive ; what could add more dignity and character to a building than a pair of massive bronze entrance doors ? What architect would not gladly welcome the opportunity of specifying nothing but solid bronze for all visible metal work ? By using improved means of manufac- ture, all the exposed door and window trim, sash, mullions, soffits, subcornices, etc., for a building, may be made of indestructible bronze for less than is often expended on perishable materials, and ornament which have less utility or architectural meaning. We always esteem it a favor to have the privilege of answering any questions arising in the minds of architects or owners who contemplate the use of bronze work, and when requested, gladly furnish sucfr details of construction or other information as, in our experience, may seem most applicable to the case. STRENGTH AND HARDNESS OF COLD-ROLLED BRONZE COMPARED WITH THAT OF CAST BRONZE Cold-rolled and drawn bronze is harder and stronger than cast bronze of like alloy, in about the proportion of 28 to 12. In other words, it has a resisting power of about 2>^ times that of cast bronze of same weight and thickness.

Y. 20 The Art of Tempering Bronze HE claim that the Eg:yptians tempered copper and bronze to carry a razor edg;e is not borne out by investig:ation. There is no piece of metal tempered by the ancients that cannot be more than duplicated to-day. An examination of hundreds of specimens, alleged to have been tempered to the degree that steel is tempered, fails to show any, and we know of no one who has seen such a work. Thus is the fable which has been believed for centuries, dissipated in the light of modern research. This is not the only story believed for centuries, tending to belittle the man of to-day, to make him the inferior of his forefathers, which fails under the search- light of inquiry and science. The ancients were chil- dren in mechanical knowledge as compared to the people of to-day, and if there were a demand for any particular building or piece of work such as was produced by the ancients, it could be duplicated and improved on by the skilled artisans of the nineteenth century. — Ex.

BANKING COUNTER RAILING Designed and made by Manhattan Brass Company for the Standard Trust Company, 42 Wall Street, New York Knowledge in Labor SKILLED workman should always be thoroug^hly familiar with the raw material he is working; or manipulating;. He should know whether it is good or whether it is poor, also whether it is perfectly adapted to the particular article he may be producing, and how it should be handled to produce the best results. Inferior materials in the hands of a workman, who possesses the proper calculation in, or knowledge of, all the details of his particular branch of work, will produce better or more satisfactory results than the very best materials in the hands of one not possessing such knowledge. He should have sufficient knowledge covering the characteristics of the material he is handling and the proper method of working it, so that whenever anything goes wrong he can detect it instantly and be in a position to locate the trouble and apply the remedy. -TTie Journal of Building. The soundness of this argument appeals to every one, and it is the basis of our strength as workers in bronze — the most com- plex of materials. We work no iron ; we work nothing but bronze and brass. Our workmen make these metals a life study. We alloy and prepare the metals in our own works, and therefore are familiar with their every peculiarity, and know how to put into each job just the kind of metals and treatment that will produce the best results at a minimum of cost. S. Y. WE ARE HEADQUARTERS IF YOU DON’T GET OUR PRICE, YOU DON’T KNOW THAT YOU HAVE THE RIGHT PRICE ABOUT PLAIN RAILINGS “BOULEVARD ” This company has been 35 years in the manufacture of Bronze and Brass Tubing for the trade, and during the time has observed that many small manufacturers of plain bronze railings, who obtained their materials from us, were, by lack of facilities and capital, compelled to manufacture at so high an expense that we could do this for them at a price less than their cost, and still have a profit left to ourselves. This has led to the gradual development in our works of a department for the finishing of plain railings, which in extent and completeness exceeds anything of its kind in America.

There is much hideous furniture within more or less hideous houses, and there are hideous statues without. ■ — N. Y. Press. V Ruskin, in his ^'Political Economy of Art," advances the argument that ar- tistic objects are a part of the national wealth, and that the government should protect those in existence from destruc- ^ tion and should promote their increase; instructing and directing its manufac- turers along artistic lines, by the estab- lishment in each community of some sort of art censorship.
