Excerpt from A Pathological Survey of the Para Rubber Tree (Hevea Brasiliensis) In the Amazon Valley In the Tropics, where plant pathology is in its beginning, it seems desirable to record all fungi on a given host, for the reason that under the conditions of clearing away the native forest, fungi which now seem unimportant may later cause disease on the introduced crop. This has been largely true in the case of Hevea. Aside from the more practical consideration given to each fungus, some details with regard to the chief characteristics of the different species and the classes, orders, families, and genera to which they belong are pre sented. It is hoped that this will give the bulletin a wider useful ness from a taxonomic standpoint and will also explain many of the terms necessarily used in a work of this kind.

Excerpt from Hevea Brasiliensis, or Para Rubber: Its Botany, Cultivation, Chemistry and Diseases, With Plates and Diagrams In the previous edition, written long before the Ceylon Rubber Exhibition, I pointed out that the industry, as far as growers were concerned, was in its infancy. The present edition has been compiled in consequence of the many advances which have been recently made in methods Of cultivation and tapping, coagulating, and curing Operations. I have, since I retired from the Ceylon Service, had signal Opportunities of studying the rubber industry from many points Of View; the wider knowledge thus gained prompted me to give a more detailed account of essential operations as carried out by rubber collectors in all parts of the world.
