THIS volume embodies the results of the exnaustive series of 

 scienlilic investigations conducted by the authors under Mr. 

 L. Lewton-Brain, director of the department of Agriculture of 

 the Federated Malay States. The researches are reported in a 

 series of twenty-seven sections or chapters. 



The results described under the section dealing with the scien- 

 tific aspects of the problem have been published previously in 

 the "Journal of the Society of Chemical Industry" and the "Agri- 

 cultural Bulletin," Federated Malay States, but are rearranged in 

 the present bulletin and a large number of experiments have been 

 added. So far as they have been previously published these re- 

 searches have been presented to the readers of The India Rub- 

 ber World in the form of lengthy abstracts. It is of interest to 

 rubber chemists to learn that the full report of the investigations 

 is now available. The authors have appended to their report a 

 reference list of 57 items covering the literature of crude rubber 

 investigations from the plantation factory and chemical points 

 of view.

This is a reprint from the "Reports of the Progress of Applied 

 Chemistry,'' Volume II, 1917, of the Chapter entitled "India 

 Rubber," etc., being an outline review of published researches 

 dealing mostly with the preparation of plantation rubber, under 

 the following topics: "Statistics of the world's output of crude 

 rubber for the past four years," "Preparation of Plantation Rub- 

 ber," "Non-caoutchouc Constituents of Rubber Latex," "Viscosity 

 of Rubber Solutions," "Theory of Vulcanization and the State of 

 Cure," "Accelerators," "Vulcanization.'' Copious references are 

 given to the original researches. 



TIRE REPAIRING AND VULCANIZING. BY HENRY H. TUFFOED. 

 William Hood Dun«oodv Industrial Institute, Minneapolis, Minnesota. 

 (Cloth, octavo, 98 pages, illustrated.) 



When the training of United States Army men in tire-repair 

 work was started by the Minneapolis Tire Dealers' Association 

 and Dunwoody Institute, the need of a special handbook for the 

 purpose was felt and the present volume was prepared to meet 

 that need. It covers the various problems which come before 

 the tire-repair man and is, therefore, a comprehensive, yet con- 

 cise, treatise giving the best practice on the different repair 

 jobs, describing the necessary tools and equipment, also devoting 

 considerable space to accounting, costs and business methods. 

 The chapters on retreads and cutting and building cord tires, 

 particularly, are of very timely interest. 



NEW TRADE PUBLICATIONS. 



•X" HE Belmont Packing & Rubber Co., Philadelphia, Penn- 

 * sylvania, is sending out "General Catalog No. 5." This was 

 formerly the Clement Restein Co., but the corporation has 

 adopted "Belmont" as both brand and company name. The 

 catalog gives an extensive list of rubber, asbestos, metal, flax 

 and hemp packings, fully described and excellently illustrated 

 both in entirety and in section. Sheet ajid wick packings and 

 steam hose are also catalogd. 



Among house-organs or factory publications "The Rubber 

 Leaf" stands out prominently for tvpographical appearance and 

 variety of contents. It is "published monthly by McGraw men 

 for McGraw men," otherwise, the employes of the McGraw Tire 

 & Rubber Co., East Palestine, Ohio. Well-edited, excellently 

 illustrated, it certainly is a model publication of its kind and one 



Bulletin No. 333 of the Link-Belt Co., Chicago, Illinois, 

 is devoted to equipment for the handling and preparation of coal 

 at the mine. Like all the publications of this company this 88- 

 1 age pamphlet is crowded with excellent half-tones, well-drawn 

 plans and diagrams, and succinct reading matter pertinent to the 

 main subject. It must be of large value to coal miners, and is 

 certainly of more than usual interest to the general reader.

Symptoms of poisoning bv and antidotes for poisonous 

 organic accelerators used in rubber work have been reprinted 

 by permission of the American Chemical Society as a chart for 

 use by factory superintendents. Copies can be obtained by ad- 

 dressing Dr. L. E. Weter, 729 Boylston street, Boston, Massa- 

 chusetts. The data given will be found in The India Rubber 

 World, issue of November 1, 1918. 



HOLIDAY GREETINGS. 



•T^HE rubber and allied trades, with their usual generosity 

 ■•• and cordiality, have sent The India Rubber World re- 

 newed expressions of good will and appreciation durii'g the re- 

 cent holidays. In return, this publication takes the opportunity 

 to extend its thanks and to assure these friends in the trade that 

 it cordially reciprocates their good wishes for progress and suc- 

 cess in the new year which appears to offer such splendid oppor- 

 tunities in every line of business.
