A most unique departure and somewhat of an innovation is the publication of Ryerson’s New Technical Library by the firm of Messrs.. Joseph T. Ryerson & Son, Chicago, iron merchants and special agerts. We had just finished the perusal of a brochure forwarded to us by the firm, entitled, ‘‘The Strange Story of SHan Dai, Pharoah’s Chief Boiler Maker,’’ a fanciful sketch written by Mr. R. R. Shuman, editor of the Boiler Maker and Sheet Metal Worker, and printed in that magazine in serial form (the pamphlet since captured by a local machinist) when along comes serials 5 and 6, also from the Ryerson Technical Library, and evidently from their bureau of printing, pos- sibly also the handiwork of Mr. Shuman, editor of the Boiler Maker and Sheet Metal Worker, presumably another publication issued by the Ryerson firm. i No. 5 takes up the subject of boiler bracing and embodies information of value to boiler makers and their foremen and layers out. It also contains a series of diagrams show- ing the head bracing and flue spacing of standard tubular boilers recommended by the Hartford Steam Boiler Inspec- tion & Insurance Company. No. 6 is devoted to ‘‘Little Giant’’ pneumatic drills, ham- mers, etc. Part I is devoted to a description of the drills, tables giving their capacity and directions for their use. Part II is devoted to descriptions and illustrations of ‘‘Little Giant’? hammers, including the new long stroke hammer. Part III will particularly interest the mechanical engineer and student of mechanics, as it isa technical treatise on hammers and drills, being an extract from a paper on: the subject by Ewart-C. Amos, a member of the Institution of Mechanical Engineers, London, England, read before that body in March, Igoo. It is stated that Joseph T. Ryerson & Son purpose issuing still other books of this series and they hope to make them all of general interest to the trade. The firm is one of the most reliable and best known in the west. Established in 1842 and incorporated in 1888 speaks volumes for the integ- rity and business-like attributes of the house. We wish this innovation of publishing technical literature by those best versed in the trade and its practical application, much suc- cess, and doubly so, as we léarn that it is free to all Milwau- kee avenue comers or senders on addressing. BRITISH SUBMARINE BOATS. Vicker’s Sons & Maxim, who are building five submarine boats for the British Navy, give the following particulars in regard to the vessels, which will soon be launched. They will be 62% feet long, 113 feet beam and will havea dis- placement of 120 tons when submerged. They will be pro- pelled by 160 horse-power gasoline engines when on the sur- face and by storage batteries when submerged. Each boat will carry a fuel supply that will enable it to steam 400 knots at a surface speed of nine knots an hour and sevea knots when submerged, The armature will consist of one torpedo tube at the extreme end of the bow, two feet underneath the water line. Each boat will carry torpedoes 113¢ feet long. The engines and the automatic moving rudders will prevent the boats from inclining at an angle while diving and rising, will keep them submerged as long as desired and will bring. the vessels to a horizontal position when submerged. The official trial will consist of a run of ten knots on the surface and two knots submerged. TREASURY DECISIONS. INSPECTION OF STEAM VESSELS. Duties of inspectors of steam vessels relative to the inspection of vessels owned by the United States. TREASURY DEPARTMENT’, August 13, Igo. Sir: This department is in receipt, by your reference dated August 8.h instant (Hon. Wm. Cary Sanger, Assist- ant Secretary), of a letter from the Assistant Quartermaster- General, U S. Army, in which is quoted a telegram from the general superinterdent army transport service, San Fran- cisco, Cal., as follows: On April 14, 1899, at request of Secretary of War, orders were issued from Treasury Department, Washington, for the inspectors of ‘steam vessels at San Francisco to thoroughly inspect army transports and certificate same in custom-house, as is done with vessels under ‘Treasury Department. This has been carried out up to the present time by officials of Treasury Department here, to the entire satisfaction of transport service. Treasury officials notify me that, under new rulivg of Supervising Inspector-General Dumont, special certificate only will be issued to transports, When the transport service was organized it was considered absolutely essential to take every precaution possible on ac- count of importance of service and large numbers of officers, troops, and civilian passengers transported, Frequent inspec- tions were made and annual inspeciions made as in the mer- chant service and properly certificated through custom-house here. I earnestly request that custom which has obtained heretofore in transport service be continued. In reply, you are informed that so much of above quoted telegram as alleges that this department, in its letter of April 14, 1899, had directed that the local inspectors at San Francisco, after examination and inspection of United States transports, should ‘‘certificate same in custom-house, as is done with vessels under Treasury Department,’’ is without foundation in fact, as you may ascertain by consulting this department’s letter of April 14, 1899, referred to, which no doubt is on the files of your department. Therefore, the Supervising Inspector-General could rot have overruled a decision having no existence. Icis true the Supervising Inspector-General reports that when he accidentally learned that the officers at San Fran- cisco were treating Government vesselsin all repects the same asthe law required of them in regard to merchant vessels subject to steamboat inspection laws he did call their attention to their misapprehension of their duties in regard to the inspection of United States transports in letter as follows: July 17, 1901. United States Local Inspectors, San Francisco, Cal. Gentlemen: Your letter of the 3rd instant, requesting that report of tonnage of United States transport Hancock be corrected from 6,001 to 5,305 tons, has been received, and the request complied with. This being a vessel owned by the United States, it should have been given a special certificate of inspection as such, and should not appear in the regular reports, to this office, but should be mentioned in a special paragraph of the annual report only. See para- graphs relating to Government vessels, fourth district, page 55, and fifth district, page 59, my annual report, 1900. JAs. A. DUMONT’, Supervising Inspector-General. The instructions contained in above letter of the Supervis- ing Inspector-General being in accordance with the practice always heretofore existing, certificates. of inspection of Government vessels not being filed in the custom-house, as is done in the case of merchant vessels, for the reason that in the latter case such certificates are required there by statute (sections 4421, 4423, and 4424, Revised Statutes of the United States), whereas ‘‘public vessels of the United States’ are specifically exempted from the above and all other statutes relating to the inspection of steam vessels. The conditions laid down in a certificate issued to a mer- chant steam vessel may be enforced by fines and penalties, whereas if such certificates were issued to vessels of the United States, the conditions of the certificate may be dis- regarded at the will of the United States officers in charge of such vessels, such certificates in such cases being practically of no more value than waste paper, and yet, if lives should be lost on such vessels, through disregard of any of the con- ditions of a certificate by the Government officers in charge, public censure would fall on this department prima facie for issuing a certificate which it had failed to enforce. L. J. GAGE, Secretary. The Secretary of War. EQUIPMENT OF A SHIP, Tube cleaners held to be articles of the equipment of a ship, and can not be withdrawn from bond freeof © duty under section 14, act of 1897, as ship supplies. TREASURY DEPARTMENT, August I5, Igor. ' Gentlemen: Replying to your inquiry of the 6th instant, whether tube cleaners used by foreign steamships lines trading between the United States. and foreign ports may be imported and supplies thereof kept in bond at New York, Philadelphia, and Boston, for the purpose of being with-’ drawn, free of duty, for use on foreign steamships leaving the United States as ship supplies, under. section 14 of the act of July 24, 1897, I have to inform you that such tube cleaners are, in the opinion of this department, properly articles of equipment of the ship, and as such can not be considered ship supplies within the meaning of section 14 of the act of July 24, 1897. Such articles can not, therefore, be withdraw from bond free of duty for the purpose stated in your letter. O. L.. SPAULDING, Assistant Secretary, William Somerville’s Sons, New York, N.
