The Preparation of Plantation Rubber

The Preparation of Plantation Rubber is a book by Sidney Morgan, with a preface and a chapter on vulcanization by Henry P. Stevens. The preface says that Mr. Sidney Morgan's work on Plantation Rubber in the East is so well known that he hardly needs introduction.

Under the heading Nurseries, the text says the usual practice is to obtain seeds from some estate which has a reputation for good yields and for exercising care in the gathering and shipping of seeds. Under the heading Stumps, the text says that at a stage, varying according to the requirements of the estate, when the plants are from twelve to eighteen months old, they are lifted from the earth. Under the heading Verandahs, the text says one of the worst features in many factories is the necessity for coolies to bring latex into the factory. The text says a compact sample of crepe as received from the East will give breaking strain of over 30 kilos per sq. cm. and over 300 per cent. elongation.
