THE INDIA RUBBER WORLD

THE EDITOR'S BOOK TABLE. 



SELF PROPELLED VEHICLES. A PRACTICAL TREATISE ON THE 

 Theory. Construction, Operation, Care, and Management of all Forms of 

 Automobiles. By James E. Homans, a.m. Second Revised Edition. New 

 York: Theo. Audel & Co. 1904. [Cloth. Svo. Pp. vii I 652. Price, $2.] 



THK object which the author has had in mind has been the 

 production of a book that would be " serviceable to own- 

 ers of automobiles and to those desiring to qualify as practical 

 i-^rt;(^if«?.f, so far as the essential knowledge may be imparted 

 by a book." He regards the automobile as a thoroughly prac- 

 tical machine, though its use has, in many cases, proved unsat- 

 isfactory — the builder often being blamed, when the fault lies 

 with the owner, who has neglected to inform himself properly 

 in regard to the construction of his machine, and how it should 

 be used. Here, in more than two score chapters, are given, in 

 simple and clear English, the principles of construction and 

 operation, including suggestions for use in cases of emergency, 

 the whole being illustrated by a large number of well chosen 

 and well e.xecuted engravings. 



Two of the chapters are headed " Solid Rubber Tires " and 

 "The Use and Effect of Pneumatic Tires." Comprising 41 

 pages, with 30 small illustrations, these chapters cover the 

 theory of the utility of the rubber tire, and suggest the fitness 

 of certain types to certain conditions, together with very full 

 instructions in regard to repairs. 



DifTerent makes of tires, as well as of automobiles, are referred 

 to, and frequent credit is given to authors and publications 

 quoted. The fact that a second and enlarged edition of this 

 book follows the first edition within two years is evidence of 

 the existence of a practical demand for such a work. 



THE AMAZON: HISTORICAL, CHOROGRAPHICAL, AND STATIS- 

 tical Outline, up to the Year 1903. By Lopes Gon^alycs. First Edition. New 

 York : HugoJ. Hanf. 1904. [Cloth. Svo. Pp. ix-i-117 ; \'ni f 11::- Price. $1.50.] 



This is the English title of a book in two parts, one half of 

 which contains the same matter in Portuguese, under the title 

 " O Amazonas." The author is a distinguished member of the 

 legal profession in Brazil, and a patriotic citizen of the Amazon 

 state, as shown by the dedication of his book to two officials of 

 the state who were influential in defending title to the Acre 

 district as against Bolivia. The book is a handy and useful 

 compendium of the history of Amazonas, and of facts regard- 

 ing its natural resources and the development of its commerce. 

 Naturally many references are made to India-rubber, which is 

 the basis of the commerce of Manaos, the capital of the state, 

 and of the shipping interests on the Amazon. The compila- 

 tion of the work was incidental to the service of its author, 

 first as a member of a commission to prepare a collection of 

 Amazonas products for the St. Louis World's Fair, and later 

 as the official representative of the state at the fair. 



BRAZIL AT THE LOUISIANA PURCHASE EXPOSITION, ST. LOUIS, 



1904. [Paper. Svo. Pp. 160 ] 

 BRAZIL. [E.XTRACT FROM THE HISTORY OF THE LOUISIANA 



Purchase Exposition, Saint Louis, 1904.] [Paper. Folio. Pp. 20.] 



The B.azilian government made an appropriation equal to 

 $600,000 for a proper representation at the St. Louis World's 

 Fair, in consequence of which, not only was there erected a 

 beautiful and extensive national pavilion, but creditable exhib- 

 its of Brazilian natural and industrial products appeared in 

 twelve of the fifteen departments of the fair. In the first of the 

 publications of which the titles are given above, it is stated that 

 the purpose is to serve rather as a souvenir of Brazil's participa- 

 tion in the St. Louis fair than as a comprehensive description 

 of the resources of Brazil, though it is expected that the book 

 will prove of value as a starting point for future investigation. 

 In spite of this modest announcement, it is not too much to 

 say that the handsomely illustrated volume before us gives a 

 better view of the manifold resources of the leading South 



American republic than has ever before appeared in the Eng- 

 lish language. The volume concludes with a classified list of 

 all the Brazilian exhibits at St. Louis, from which it appears 

 that specimens of rubber formed a part of no less than 16 ex- 

 hibits, from the states of Giao Para, Amazonas, Bahai, Matto 

 Grosso, and Sao Paulo. The second publication mentioned 

 is a well drawn up and handsomely illustrated description of 

 the Brazilian Pavilion and its contents, with references to the 

 principal resources of the republic.

This is a guide to computing the weights of rubber goods of 

 whatever kind, for the use of factory workers, dealers, or buy- 

 ers of rubber goods, of particular use in cases where the sell- 

 ing price, considered in relation to weights, in any sense indi- 

 cates quality. Likewise, the specific gravity of rubber com- 

 pounds is indicated. The weights of rubber tubes and rings, 

 with the most usual dimensions of thickness, diameter, etc., 

 are given in tabular form, together with like details for threads, 

 valves, buffers, and the like. 



JUBILEE OF THE PLANTERS' ASSOCIATION OF CEYLON. 1854-1904. 

 Illustrated Souvenir of the 7~//«^j i?/ C^-y/cn. Colombo: 1904. [Svo. 4S pages.] 



The association here named has done a work of incalculable 

 value in advancing planting interests in Ceylon, and its lead- 

 ers, whose lives are briefly sketched in this pamphlet, deserve 

 a prominent place in the history of the island. To-day the 

 association is devoting to the rubber planting interest, de- 

 scribed in Mr. Pearson's letters in The India Rubber World, 

 the same intelligent attention that, in earlier years, it gave to 

 coffee, tea, and other products, and there is reason to believe 

 that the results will be equally satisfactory.

THE COLORADO RUBBER INTEREST. 



THE Riverside Crude and Refined Rubber Co. was incor- 

 porated August II, 1904, under Colorado laws, with 

 $1,000,000 capital authorized, and with principal offices to be 

 located in Denver. Simon L. Woodbury, George Leonhardy, 

 Daniel D. Long, and others, are named in the incorporation 

 papers. Mr. Leonhardy writes to The India Rubber World 

 that the object of the company is " to gather the plant "—re- 

 ferring to the recently much discussed Colorado rubber shrub 

 — "and manufacture the rubber therefrom, which we have ex- 

 perimented with and found beyond doubt that we can do."
