THE INDIA RUBBER WORLD 



241 



M. C. Whitaker, that Columbia College, Xew York, has es- 

 tablished a three-year course of study leading up to the Post- 

 Graduate Engineering Course. The former includes analyti- 

 cal geometry, chemistry, shop work, calculus, physics, statics 

 and surveying. 



Professor W'hitaker's paper is supplemented by a number 

 of illustrations, showing the principal features of the labora- 

 tory attached to the new department. This laboratory it is 

 proposed to use both for instruction and investigation. 



.\ subject of importance is dealt with in Dr. L. 11. Baeke- 

 land's i>aper on the "Protection of Intellectual Property in 

 Relation to Chemical Industry," in which the various aspects 

 of the subject are fully considered. Another paper of a gen 

 eral character is that of Mr. W. M. Booth, on "Water for 

 Industrial Purposes," in which it is pointed out that before 

 •deciding on the location of a new factory a thorough study 

 should be made of water conditions, under the heads of manu- 

 facturing requirements, drinking water and water for fire- 

 e.xtinguishing purposes. It is recommended that two inde- 

 pendent sources of supply should be available in each case. 



"The Beehive Coke Oven Industry of the United States" is 

 treated by Mr. A. W. Belden, of the Bureau of Mines, in a 

 comprehensive paper in which the history of the coke indus- 

 try since its establishment in 1817 is outlined, as well as its 

 present conditions. Plans of coke furnaces supplement th; 

 text. "Acetylene Solvents" are discussed by Professor J. H. 

 James, under the heads of laboratory methods and tests and 

 laboratory results, accompanied by a series of diagrams. 



Cement and allied subjects are handled in six papers: "The 

 Temperature Gradients in Setting Portland Cement," by 

 Allerton S. Cushman; "Potash from Natural Silicates," by Mr. 

 Cushman, in conjunction with G. W. Coggeshall; "Setting 

 Time of Portland Cement," by E. E. Ware; "Paving Block 

 Impregnation," by John Hayes Campbell; "Blast Furnace 

 Slag as Brick Material, by Professor Albert E. White; and 

 "Potash, Silica and Alumina from Feldspar," by Professor 

 Edward Hart. 



Various other special subjects were dealt with in tlic fol- 

 lowing papers: "Oxygen in Petroleums and Asphalts," by 

 Dr. S. P. Sadtler; "Decomposition of Linseed Oil during 

 Drying," by Professor J. C. Olsen and A. E. Ratner ; "Opacity 

 of Pigments," by G. W. Thompson; "Eflfect of Lime Sulphur 

 Spray on the Eyesight," by Professor James R. Withrow; 

 and "Phenol-Formaldehyde Condensation Products," by Dr. 

 L. H. Baekeland. 



The chemistry of food products is represented by "A 

 Chemical Investigation of Asiatic Rice," by A. S. Cushman 

 and H. C. Fuller, and by "Disinfectants in Sugar Solutions," 

 by George P. Meade. 



The "Transactions" of this representative institute thus 

 afford a view of recent technical progress in the various 

 branches of industrial science. By grouping the papers a 

 still clearer idea is gained of their application. Not only as 

 a record of the work of the institute, but as a standard text 

 book, the chemical engineer will appreciate the value of this 

 summary, reflecting, at it does, the latest achievements in the 

 world of technology. 



•CRENIER'S RUBBER ANNU.\L 1913. KUALA LUMPUR. FEDER- 

 ated Malay States. Charles Grenier & Son. [Paper, 64 pages, 12x9, 

 with SO illustrations.] 



In the editorial introduction to this welcome annual the 

 anticipation is expressed that the time of tribulation through 

 which the rubber trade is now passing will come to a happy 

 ending. The industry, it is added, will come out of the 

 present ordeal like refined gold. Reviewing the late develop- 

 ments of the rubber trade, it is remarked that, barring the 

 question of prices, the rubber industry has not had much to 

 disturb the even tenor of its way. Outputs have in most 

 cases far exceeded anticipation. A satisfactory feature of 



the outlook is the prospective abolition of the Federated 

 Malay States export duty on rubber. 



The literary matter in the -Annual maintains its accus- 

 tomed standard: the life of Charles Gi>ndycar being dealt

with by Mr. Edward Salmon, while Mr. Arthur Shepard dis- 

 cusses the "Wild Rubber Position" in connection with the 

 elimination of inferior grades. "The Case for Standardiza- 

 tion" is outlined by Mr. G. S. Montague, and an interesting 

 comparison of plantation costs in Malaya, Ceylon, Sumatra 

 and Java is furnished by Mr. J. F. -Ashby. To those finan- 

 cially interested in rubber ventures, an article by Mr. W. A. 

 Tinnock on the "Valuation of Rubber Shares," will specially 

 appeal.

illustrated reviews of some 80 plantations, thereby bringing 

 the reader into close touch with Malayan conditions. 



The illustrations, two of which are here reproduced, have 

 been artistically executed and form an attractive feature of 

 the "Annual." 



DR. DE TOLEDO SUPERSEDED. 



The Bureau of Foreign and Domestic Commerce, Washing- 

 ton, D. C, has informed The India Rubber World that Dr. 

 Pedro de Toledo has been superseded as Brazilian Minister of 

 Agriculture. It is understood that his successor is Dr. Edwiges 

 de Queiroz. The late minister had, it will be recalled, been 

 prominent in the development of the "Defesa da Borracha," or 

 Bureau for the "Defense of Rubber." Reports state that the 

 policy of this bureau has not been abandoned, but that its scope 

 has been greatly decreased. It is further stated that Dr. Toledo 

 has been appointed by the President as Brazilian Minister in 

 Rome.
