The book deals with the practice of using graphite. for air 'cylinder lubrication, which is endorsed by leading engineers. The booklet is well printed and well il- lustrated, and is worth having. J. We. "Atlee, Riverton," Ne J. has issued a circular concerning the Atlee portable cargo batten cleat. The cleats are of various types for angle bulb frames, channel frames, re- verse frames and plain angle frames. As no bolts or nuts are required they can be quickly removed and replaced, and are represented to keep the in- side of the ship as clean as the out- -- side. . The thirty-third vessel is now being equipped with this fitting, in- cluding nearly all of the recently-built ships of the following lines: Ward line, Mallory line, Morgan line, Clyde ltmes Atlantic. Transport. Co.;" Phila- delphia & Boston Steamship Co., Por- to ico Steamsiip: Co... and. the Oceanic Steamship Co. La Favorite Rubber Manufacturing Co., Patterson, N. J., manufacturers of Perry's specialties, have just put out a catalog descriptive of Perry's packings. The catalog gives complete descriptions of the various makes of Perry packings and is well illustrated throughout. The catalog contains a fine endorsement of the Brown sheet packing by Chief En- gineer J. G. Rendall of the steamer City of Erie. This packing was used to pack the steam joints of the steamer prepara- tory to her race with the steainer Tash- moo, which, as is well known, the City of Erie won. Chief Engineer Rendall says that~ Perry brown sheet packing held. an important part in the trial, as the steamer's success depended to a great extent on the packing used in the steam joints. Chief Rendall adds that this same packing, applied more than three years ago, is still in service and doing good work. The catalog is well de- "two per Cent. signed and of convenient size and will be sent to anyone interested upon re- quest. The Western Electric Co. 259 South Clinton street, Chicago, have just issued a. catalog descriptive of their new I10 acre plant at Hawthorne, Hl. This com- pany hitherto has been principally men- tioned with the manufacture of telephone apparatus. Since completion of the Hawthorne works, however, it is in posi- tion to build electric power apparatus and switch Loards up to and including the largest sixes used for railway pur- poses. A feature of its new plant is the extraord.nary precaution which it has made against interruption of work. For instance, continued uncertainty as to the coal supply has led it to construct two storage bins, one of 4,000 tons and the. other of 10,000 tons capacity, both lo- cated below the normal ground level. - Into these bins coal is supplied directly from the cars and taken out by means of a locomotive crane fitted with a grab bucket. The company is profiting by the tests recently made at Portsmouth by the British admiralty concerning the heating value of coal when left exposed to the air. These tests ap- pear to prove that coal loses nearly 30 per cent of heat value in six weeks if left open to the air. The company accordingly keeps its bins flooded and estimates that the loss is reduced to Thorough safeguards have also been taken against fire. In addition to a reservoir a water. tower is provided with six steel tanks, with # total capacity. of 213,000. gallons, connected with an automatic sprinkler system running to every building 'ex- cept the foundry, forge shop and main body of the machine shop, in which buildings there are absolutely no com- bustible materials. The plant is equip- ped throughout with the latest ma- chinery. The ship building trade in Britain has hardly maintained lately the promise of the earlier months of the year, but some good contracts are now being placed. The most important recent one is for a battleship of the Dreadnaught type, which has been placed with Armstrong, Whit- worth & Co., Newcastle. The machinery is to be furnished by the Wallsend Slip- way Co. There are two sister ships building in the dock yards, and the en- gines for these are to be supplied by the Fairfield. Co., Glasgow, and Hawthorn, Leslie and Co., Newcastle. The engines are to be delivered within two years, and for any delay beyond that period there will be a penalty of £100 per day. The new battleships are to have a displace- ment of 18,400 tons, which exceeds that of the first Dreadnaught. The' Dread- naught vessel is to be named the Superb.
