to prevent the destruction of rubber vines. 
The cultivation owing to the slow growth and uncertain yield 
has not met with any success, though the rubber is one of the best 
on the market. Some experimental plantations on the Ivory Coast 
begun in 1906 have not induced the natives there to take up the cul- 
tivation (Chevalier, Bull. Soc. Nat. d'Accl. France, 1912, p. 134), 
and the planting of rubber vines in the Congo Free ‘State has been 
going on since 1900 until (1913) it was estimated that 12,000, 
were growing in the various plantations, without profit, ‘the cost 
of planting not having been returne xperiments there have 
shown that 64 Ib. of rubber from 800 plants on an acre of ground 
could be expected after 10 years growth (Cons. Rep. Ann. No. 
5043, 1913, p. 20).
