THE INDIA RUBBER ^VORLD 



[June i, 1901. 



LITERATURE OF INDIA-RUBBER. 



MANUAL PARA LA EXTRACCION Y BENEFICIO DE LA GOMA ELAS- 

 lica. [Porl Nicanor Jordan S. La Paz : 1900. [I'jper. lamo. pp. 55, with 

 plates and foldinf; table.] 



AS HEVKAS OU SERINGUFIRAS. INFORM A(;t'JES POR J. BARBOSA 

 Rodriqucs, Director do Janlim Botanico do Rio de Janeiro. Rio de Janeiro: 

 Imprensa Nacional, iqoo. [Paper, isnio. pp. 86, with folding tables.] 



THESE two brochures, one in Spanish and one in Portu- 

 guese, are alike In that each indicates, in the country of 

 ts origin, a growing interest in placing the collection of rubber 

 under intelligent supervision, and a desire on the part of the 

 government to forward such a condition. The Bolivian pam- 

 phlet is issued by the " oficina nacional de immigraclon, esta- 

 distica, y propaganda geografica," and that from Brazil, as its 

 title indicates, from the government botanical garden. Both 

 touch to an important extent upon methods of extraction and 

 coagulation, and refer to cultivation as worthy of attention. 

 The report by Senhor Rodriques includes a comprehensive 

 summary of Para rubber statistics since 1827. Both reports 

 contain plates illustrating the various rubber species. 



AU PAYS DU CAOUTCHOUC. PAR EUGENE ACKERM ANN, INGENIEUR 

 Civil des Mines. Rixheim : F. Sutter & Cie. 1900. [Paper. i6mo. pp. 

 61 -h 3 photogravures. 1.50 francs.] 



While professionally employed at Para, M. Ackermann 

 gave careful study to the rubber situation on the Amazon, 

 reaching the conclusion that, in spite of the immense area of 

 the rubber territory, the great difficulty of obtaining labor will 

 long prevent the production from keeping pace with the con- 

 sumption. M. Ackermann urges the taking of steps to con- 

 duct the rubber gathering industry in a more scientific and 

 sanitary manner, and advises The India Rubber World 

 that he will undertake to locate some rubber concessions on 

 the Amazon, iu which work he solicits the cooperation of cap- 

 italists. 



UEBER KAUTSCHUKLIANEN UNO ANDERE APOCYNEEN. NEBST 

 iiemerkungen liber Hevea uod einen Versuch zur Lijsung der Nomenklatur- 

 fra^e. Von Dr. Hans llallier. Hamburg : Lucas Griife & Sillelu. 1900. 

 [Large Svo. pp. 19-2161 4 plates.] 



This monograph, reprinted from the "Jahrbuch der Ham- 

 burglschen WIssenschaften Anstalten " (Rund XVII, 1899), 

 forms the most complete study yet attempted of the African 

 rubber producing genus Landolphia, in the course of which 

 the author attempts, by comparison of all the existing data, to 

 catalogue the Landolphia species, of which more than twenty 

 are named, to say nothing of the synonyms which have found 

 their way into print, through the naming of identical species 

 by different observers. The natural order Apocynacete em- 

 braces other rubber producers, including the Corpodintis, Wil- 

 loughbeia, etc., but more especially the //^t/f(z (Para rubber tree), 

 all of which receive more or less attention In this work. 



The Straits Settlements Agricultural Bulletin (No. 9 — 1900,) 

 published from the botanic garden at Singapore, contains a 

 catalogue of " Native Rubbers of the Malay Peninsula,'" which 

 is fuller than any other that has yet appeared In print. The 

 writer of the article thinks that the unfavorable verdict of the 

 trade regarding some of the species named will be reversed 

 when, under more intelligent supervision, better methods of 

 extracting and coagulating the rubber are Introduced.
