Book excerpt: Excerpt from The Cultivation and Preparation of Para Rubber Although the cultivation Of Para rubber is at the present time almost limited to a few countries in the Eastern Tropics of the Old World, there is every prospect of its being further extended in those regions, and also of being taken up largely in the Western Tropics. There are in Tropical Africa thousands of square miles Of land suitable for the cultivation of the Para rubber tree. Upon a large extent of this land rubber-producing plants were at one time abundant, but now year by year their number is being gradually diminished, as the result Of the disastrous methods Of tapping employed by the native rubber collectors. The question of replanting these areas with Para rubber trees is well worth the consideration of the administrative authorities, and especially those in our various West African possessions.
