rode over this whole planting, visited the four camps where the native 
workmen live in palm thatched houses, and examined the rubber trees on 
the hilltops, on side hills, and in the valleys, and when we were told 
that the stand of rubber embraced fifteen hundred acres, all cleared,

Indeed, the next great problem that is to confront the rubber 
planters is that of tapping and preparing for market. One has only
