HEVEA PLANTING IN BELGIAN CONGO. 



A systematic effort to establish Hcz-ea plantations in the Bel- 

 gian Congo Colony on a scientific and practical foundation, as 

 has been done in Malaya, is being made at Yangambi, near 

 Stanleyville, on the river Congo. A committee which examined 

 conditions has reported in the "Bulletin Agricole du Congo 

 Bi-lgc" Planting was begun in 1911, when 11,431 trees were set 

 out on a little over 115 acres of ground; two years later 26,750 

 more trees were planted on 326 and a fraction acres, making a 

 total of 38,191 trees on 441;/2 acres of land. The trees are 

 planted nearly 22 feet apart or 825/2 to an acre. 



.All that relates to rubber cultivation was studied : the general 

 conditions of growth, the care of the trees, the manner of tap- 

 ping, the rubber crop and output, the treatment of the product, 

 the by-crops, such as coffee, the enemies and diseases of Hevea, 

 ihe provision for water and the measures to modulate the rain- 

 fall. 



It seems that the reputation of Belgian Congo rubber is not 

 very favorable in Europe; there need be less justification for 

 this hereafter. The conditions found in Yangambi, such as good 

 climate, the right kind of soil and suitable facilities for exporta- 

 tion to foreign lands, give promise of as successful results as in 

 Malaya, Java and Sumatra, if the same methods are used as in 

 those countries. Too great profits must not be e.xpected at 

 the beginning and modern methods must be employed. 



Belgian Congo has a great advantage over the Far Eastern 

 plantations in that labor is cheaper there than in the Indies, 

 and the experience of the Yangambi plantations has shown, 

 moreover, that the labor is not only useful for rubber culture 

 but skilled in it. Some contract laborers are needed at first to 

 teach the delicate and accurate work requisite in tapping for 

 the latex ; but the labor question seems to be one that is easily 

 settled on the Congo, and the future of Hcvea culture there 

 >eems to be by no means unfavorable.
