plete table of gravimetric factors, and other important addi-

 chemical laboratory. 



NEW TRADE PUBLICATIONS. 



J P. DEV'IXE CO., manufacturer of \'acmnn dryers, solvent 

 • recovery apparatus, and other lines for similar purposes, 

 has just published its "Miniature Bulletin No. 105," descriptive of 

 apparatus required mainly by the chemical and allied industries. 

 But containing some notice of apparatus used in rubber goods 

 manufacture, chiefly autoclaves, kettles, and vaciuim dryers. The 

 bulletin is a small one, measuring about four by six inches, con- 

 taining 32 pages, of which most of the left hand ones are blank. 

 Each right hand page has a strikingly effective cut of one 

 specialty, with a terse description, well displayed. A view of the 

 experimental laboratory is interesting, and the pictures of the 

 exterior and the interiors of the plant show the extent of the 

 establishment.

The Southwark Foundrj' & Machine Co.. Philadelphia, 

 Pennsylvania, issues its catalog of valves and presses in a self- 

 binder which enables its customers to keep it constantly up 

 to date. Each page, S'/i by 11 inches, is devoted to one or 

 more cuts and description of a single machine, the cuts being 

 wonderfully well-executed half-tones from retouched photo- 

 graphs, and the descriptions comprehensive and accurate. 

 The steam platen presses, tire-forcing presses, bead presses, 

 hydraulic heater presses, quick opening vulcanizer doors and 

 other specialties for the rubber manufacturing industry are 

 fully presented in the latest issue.

The Akr'^iii Rnbbe\ Mold & Machine Co., Akron, Ohio, is 

 sending to the trade a very complete catalog of its specialties 

 for tire building anxl tire manufacturing. This contains in its 

 48 pages practically every mechanical requirement for these 

 important lines of industry. The machines and other items of 

 equipment are well illustrated, the cuts showing finely all the 

 details, and each is fully described. To give a list of these 

 would demand more space than is available, but the catalog 

 is one well worth securing and filing.

Gutta Percha & Rubber, Limited, Toronto, Canada, sends out 

 its catalog of Maltese Cross Rubbers, season of 1917-1918, in a 

 finely printed book of 64 pages, with covers handsomely illu- 

 minated with the trade-mark of the company. The styles and 

 shapes are pictured in excellent half-tones, and tlie descriptive 

 text is given in both English and French. With this is sent a 

 smaller booklet, containing net prices, particulars regarding 

 packing, and other information of the line.

"War Loans and the United States" is the title of an absorbing 

 pamphlet, issued by the Guaranty Trust Co. of New York, which 

 reviews the loans made by our own country in its wars, from 

 the outbreak of the Revolution to the end of the Spanish war; 

 deals with the general subject of loans in connection with the 

 present war in Europe; and discusses our lessons of the past 

 and economic opportunities of the future. Our phenomenal gain 

 in export trade and resulting increase in financial strength is de- 

 tailed, and the plain obligation imposed upon us in holding 30 

 per cent of the world's total supply of gold is pointed out. It is 

 conclusively shown that "a lending policy on our part would not 

 only prove a species of protective insurance, but in effect would 

 remove us from the debtor nation class to which we have here- 

 tofore belonged and might raise us to the very pinnacle among 

 creditor nations — a class whose commercial prosperity is assured 



and whose foreign trade relations are most permanently e.stab- 

 lished."

The American .\siatic Association is sending out its monthly 

 magazine under a new title, "Asia," and in a new and very at- 

 tractive shape. The number for March consists of 80 quarto 

 pages, finely illustrated, containing articles of value to those in- 

 terested in the Far Eastern trade. The present number is de- 

 voted almost entirely to China and Japan, though there is also 

 an able article on the Philippines by Manuel L. Quezon, former 

 resident commissioner of the Philippine Islands and now presi- 

 dent of the senate of the first Philippine Congress.

The Diamond Power Specialty Co., Detroit, Michigan, sends 

 us a finely printed pamphlet entitled "Increasing Today's 

 Profits," exploiting the soot blower manufactured by that com- 

 pany. It contains some interesting matter as regards the saving 

 of heat and power by elimination of soot deposit, and explains 

 how this deposit acts as a heat insulator. Illustrations of fac- 

 tories where this system is in use, diagrams, recording charts, 

 and ledger sheets are reproduced to prove the claims set forth 

 in the booklet.

John Burnham it Co., 115 Broadway, New York City, have 

 compiled for free distribution a statistical card which will be of 

 interest to holders of motor and rubber stocks. It includes 

 capitalization, par value, present l)id and asked markets, dividend 

 rate and date of payment, percentage earned, high and low 

 prices for 1916 and the production of the year in number of 

 cars or gross sales of the leading automobile, automobile ac- 

 cessory and rubber companies.

According to the latest census of motor vehicles in Great 

 Britain, the total number of automobiles and trucks in actual 

 service is 171,607, about 5 per cent of the number registered in 

 the United States on January 1, 1917, which was 3,541,738. In 

 each of the seven states of New York, Ohio, Pennsylvania, Illi- 

 nois, California, Texas and Iowa, there are more automobiles and 

 trucks than in all of Great Britain. In the United States the, 

 production of cars for 1916 was well over 1,600,000, 



A recent number of "Class," a journal devoted to trade and 

 'class-journal advertising, has an interesting article by Julius S. 

 Holl, advertising manager of the Link-Belt Co., Chicago, Illinois, 

 which might well be read and even re-read by all who have 

 charge of the advertising and sales departments of large or 

 small industries. It is a sort of confidential talk based on the 

 writer's experience over a wide field, and a profitable expenditure 

 of hundreds of thousands of dollars in trade journals.

The "Charlotte (North Carolina) News" has published an is- 

 sue of 88 pages, devoted almost entirely to descriptions of the 

 many textile mills in that state. Each plant is treated individ- 

 ually, pictures and text giving a very complete and compre- 

 hensive review of the cotton mill industry. The work was done 

 by an independent investigator, a trained newspaper man, and 

 one of the main objects, evidently, is to rectify some of the im- 

 pressions caused by sensational reports of the conditions of the 

 mill-workers of the South. The paper is a credit to the enter- 

 prise of this daily publication, and is one which shows the pros- 

 perity and extent of the cotton weaving industry of the "Old 

 North State."

The Underwriters' Laboratories "Electrical Data" gives a 

 brief review of the institution, and the work carried on in 1916. 

 Following this are described in detail fires and accidents reported 

 due to electrical causes, with results of investigations. Illus- 

 trations of some of these accidents, also views of the laboratories 

 are shown.
