No examination of the bark or bast has yet been made to test the cause of this observed fact, which is not in agreement, it is believed, with experiments made elsewhere on rubber yielding trees and plants of other species. But an enquiry will be instituted with the help of Dr. Watts, the Government Economic Reporter, and the Director of the Forest School, with the view of obtaining informa- tion on the point. In the meantime, it seems safe to hazard the opinion that the rubber cells must be placed in more or less vertical rows, and that, in fact, in arrangement they resemble somewhat an arterial system, when it will be readily understood why a horizontal cut must be much more effective in tapping their contents than a vertical or oblique cut of equal length. 11. Another point was tested at the same time by the Conser- , vator, which perhaps helped to create the Rubber residuum and • • ,1 , . 1 , • • • wastage discussed. opinion that the tapping operations, as per- formed in 1898-99, were of an unnecessarily careless or wasteful nature. Allusion is here made to the fact that, when the rubber is stripped from the cuts, a milky, and sometimes copious, residuum runs out of the wounds down the tree, and as no arrangement is made to collect this overflow, the impression may have been carried away that it represented wastage. But the Con- servator was able to prove to his satisfaction that this residuum, which closely resembles rubber milk in appearance, contains no caoutchouc, and is capable of being practically absorbed by blotting paper or of being evaporated in the sun. In fact, it consists practi- cally of little else than water and contributes no appreciable pro- portion of the true wastage, which seems to be wholly represent
