Excerpt from Experiments in Tapping Ceara Rubber Trees

In these, and the other experiments reported below, it was found that latex, unmixed with rain water, and in a thin layer in the bottom of the pan, would coagulate in about one-half hour. Latex, which remained attached to the side of the tap ping wound was coagulated sufficiently for stripping off the scrap rubber, after one hour. When the latex was left at a depth of an inch or more in the pan, it sometimes required from one to two days for coagulation. The addition of water, either from rain or with deliberate intent, delayed coagulation considerably in every instance.

With regard to the economic handling of laborers in tap ping rubber trees, it was found that the men could be kept at work for one-half day at tapping and collecting, and that in the afternoon they could be utilized in washing rubber and utensils, or at cultivation or various other lines of work on the plantation.
