RUBBER IK THE OEEMAK COLONIES. 



Professor Warbvrg, m a paper on "Der Kautschuk in dem 

 Deutschen Kolonien," read before the international agricul- 

 tural congress at the Brussels exhibition, presented the fol- 

 lowing summary of the extent of planting in those colonies. 

 His figures related to hectares, which are converted here into 

 acres: 



.^cres. 



German East Africa (almost exclusively Manihot) jo,ooo 



Kamerun ( chiefly Kickxia with some Hevea) io,ooo 



Togo (chiefly Maiiiliot with some Kickxia) SOO 



New Guinea (chiefly Ficus with Castilloa and Hevea) 6.250 



Samoa (Hevea) 2,500 



Total 39.250 



The synopsis made by Professor Warburg would indicate 

 the following division of this acreage among the various spe- 

 cies: Manihot, 19,750: Kickxia. 10.000; Ficus, 5,000; Hevea, 

 3,750, and Castilloa, 705. 



"HEVEA.' 



'CASTILLOA" OR "CEARA.' 



IN discussing the question of the most suitable variety of rubber 

 for the contemplated development of Costa Rican plantations, 

 Seiior J. E. van der Laat. Editor of the Boletin de Fomento 

 (organ of the Costa Rican Ministry of Commerce), has grouped 

 in concise tabular form the principal concrete facts available 

 with regard to Hevea. Castilloa and Ccara. These three classes 

 of rubber tree are. he considers, the only varieties deserving con- 

 sideration. As he remarks, each of them has a natural zone, 



where conditions are specially favorable and where the attempt 

 to introduce any of the other classes would be a short-sighted 

 policy. In view, however, of the fact that these natural zones 

 are infrequent, he recommends the adoption in each instance of 

 the variety presenting the greatest advantages under the different 

 local conditions. 



For the purpose of making the desired comparison. Sefior van 

 der Laat recommends making trials of Hevea and Ccara in 

 different zones ; thus establishing for these varieties results to 

 be compared with those on record for Castilloa, hitherto exclu- 

 sively used for Costa Rican plantations.
