' ' Experiments in Malaya have shown that the first four feet from the base contain the maximum amount of latex, but a height of six feet is allowed by many planters. It is well known to planters in Ceylon that the quantity of latex obtained at five to six feet from the ground is little more than half that at the base of the trunk ; nevertheless, a jdeld of over i to 3 lb. of rubber, per tree, is expected on certain estates by tapping the area from six to ten feet above ground.
