Excerpt from The Rubber Industry in the Territories of Manica and Sofala The system, which at one time Obtained, Of cutting up the vines into short pieces for the purpose of extracting the latex is now quite abolished. That which is now generally employed consists in cutting Off slices of bark from the mature stems. Providing these incisions be not made unnecessarily long or deep, nor too close together, this system of tapping cannot be considered drastic, and is certainly far less injurious than many methods in vogue in other parts Of Africa. As the majority Of the laticiferous vessels traverse the bark of Landolphia Kirkii in a longitudinal direction, a transverse incision Obviously taps more vessels than a longitudinal one of the same length. Measures are, therefore, being taken with a view of introducing a system of tapping by means Of transverse incisions in order to reduce to a minimum any injury caused to vines by the excision Of bark.
