THE INDIA RUBBER WORLD

LITERATURE OF INDIA-RUBBER. 



NEW TRADE PUBLICATIONS. 



KOLONIAL-WIRTSCHAFTLICHES KOMITEE. KUNENE-SAMBES1 EX 

 pedition. H. Baum. Berlin: 1^03. [Cloth. Bvo. Pp. xi 193 4- map, 13 

 plates, .mil ios illustrations in the text. Price, 20 marks.] 



THE West African river Kunene, flowing into the Atlantic 

 at 17 30' S. latitude, marks for some distance the bound- 

 ary between German Southwest Africa, on the south, and the 

 Portuguese colony of Angola, on the north. The boundary 

 line projects beyond the Kunene, nearly half across the conti- 

 nent to the Zambesi. North of this boundary, from the Atlan- 

 tic to the Zambesi, and within the limits of Angola, lies the vast 

 concession of the Companhia do Mossamedes, with 25,000,000 

 francs capital, out of whose plans grew the suggestion of a rail- 

 way from Port Alexandre, on the seacoast, to the Transvaal, 

 and it was to report upon the little known country along the 

 proposed route that an expedition was planned, in which the 

 semi official German Colonial Economic Committee joined, 

 llerr Baum, the representative of this committee, and a botan- 

 ist of note, has reported in this volume a resume of the tour 

 to the Zambesi and return, and in detail on the resources of the 

 country, while assistance has been rendered by members of the 

 staff of the roval botanic museum at Berlin and by other ex- 

 perts in reporting on the collections made on the expedition. 

 Professor Dr. Warburg contributes a summary of the botanical 

 results. There are likewise expert reports on the zoological 

 collections, and so on. 



The interest of the work for the rubber branch lies in the 

 very complete accounts given of " root rubber " {wurzelkaul- 

 schuk), which abounds through a great part of the region trav- 

 ersed, practically no other rubber being found there. Descnp- 

 tions are given of the leading species yielding this rubber, with 

 views of the plants, and of all the steps in the native process of 

 preparing rubber from them. The book is in fact the most im- 

 portant contribution yet made to the world's knowledge of this 

 singular class of plants, from which so much rubber has been 

 obtained underground, without its source being understood 

 until recently. The region in which this work was studied par- 

 ticularly was in the sandy plains of eastern Angola, among the 

 rivers flowing into the Zambesi. 



The book is handsomely printed and richly illustrated, in the 

 style of the reports published by the same committee on India- 

 rubber expeditions to West Africa and Central and South 

 America, mentioned already in these pages.
