Excerpt from Rubber: Its Sources, Cultivation, and PreparationThe successful production of Para rubber in South America is more than two centuries old, and it is still mainly conducted on the most primitive lines and with the wild trees of the forest, which are of great age. So far as the actual preparation of rubber is concerned, these primitive methods have succeeded in placing on the market a material which is on the whole well suited to the requirements of the manufacturer, so much so that fine hard Para obtained from the wild trees of South Merica is still the market standard of the material.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
