DR. DE WILDE.VIAN has become widely recognized as an 

 authority on the subjects to which this important book 

 relates, through his work as conservator of the state botanic 

 garden at Brussels, as professor in the horticultural school at 

 Vilvorde (Belgium), as a member of the permanent commis- 

 sion of the Congo museum at Tervueren, and as a contributor 

 to botanical and other technical journals. Though this book 

 is devoted to a number of plants of economic value, nearly 

 one half of its pages and 21 of its 38 photogravures relate to 

 Caoutchouc, showing the great importance the future exploita- 

 tion of this product holds in the mind of the author. In these 

 pages has been admirably compiled a list of rubber yielding 

 plants, of whatever country, and their natural conditions of 

 growth, with notes on the qualities of their product, to serve 

 as a guide to intending planters, particularly in Africa. Meth- 

 ods of extraction and coagulation of rubber are also discussed, 

 embracing a full treatment of the subject of mechanical treat- 

 ment of latex. In addition, there are extensive notes on the 

 planting practice, to date, with the various species, in different 

 regions. Nothing else quite so complete under these various 

 heads has yet appeared in a single publication, and Dr. De 

 Wildeman has rendered the rubber cultural interest an impor- 

 tant service. One thing which it is impossible for such a 

 work to contain, as yet, is a compendium of results of planting 

 rubber species outside of their native habilat, and this is a 

 most important problem, which time alone can solve. 



NOTES ON LAYING. REPATRING, OPERATING, AND TESTING SUB- 

 marine Cables. U[nitcd] S[tates] Signal Corps. By Captain Edfrar Russell, 

 Signal Corps. With Supplementary Chapter on Factory Testing. By Lieuten- 

 ant Colonel Samuel Reber. Military Secretary, Washington : Government 

 Printing Office. 1952. [Cloth. Svo. Pp.70.] 



The signal corps of the United States army has had so much 

 to do of late with submarine cable working that the chief sig- 

 nal officer. General A. W. Greely, has deemed desirable the 

 compilation of a manual for the use of members of the service 

 engaged in the branches of work referred to in its title, quoted 

 above. The various matters can, of course, be treated only in 

 the briefest manner in so small a volume, but the larger litera- 

 ture of cable working is cited freely, for the benefit of those 

 who would inform themselves more fully. This manual is all 

 the more interesting because it relates throughout to submarine 

 cables insulated with India-rubber, and, to Americans at least, 

 because the cables operated by the signal corps — in the Philip- 

 pines, Alaska, and elsewhere — were made in the United States 

 and mark the establishment 01 a new branch of the rubber in- 

 dustry in this country. There are included some data of inter- 

 est regarding the electrical properties of the various insulating 

 compounds employed in the construction of the government 

 cables. 



ETUDES POUR UNE PLANTATION D'ARBRES A CAOUTCHOUC. 

 Par Octave J- A. Collet. Brussels : Falk Ills. 1902. [Paper. Svo. Pp. 45.I 



A SUMMARY of observations by the author, in Java, Su- 

 matra, and the Malay peninsula, of experiments made in 

 planting /'/iTw.f elas/ica and Hevea Brasih'ensis, upon which he 

 has based estimates of the cost of establishing plantations and of 

 the profits possible. No such estimates, of course, can be of any 

 value outside of the region and the particular conditions for 

 which they are designed. The brochure is of interest, however, 

 because of its detailed information regarding the rate of growth 

 of rubber species under cultivation under certain circumstances, 



and there are a dozen good views, from photographs, of planta- 

 tions in the countries above mentioned.
