"In some cases, the worker has to walk one or two days every fort night, and sometimes more, to get to the place of the forest, where it can be found in rather great abundance, the rubbery lianas. There, the collector leads, for a certain number of days, an existence wretched. He must build himself an improvised shelter, which obviously cannot replace his hut, he does not havenot the food to which he is accustomed, he is deprived of his wife, exposed to the elements of the airand the attacks of wild beasts. His harvest, he must bring it to the post of the State or the Company, and it is only after that, that he returns to his village, where he can hardly stay for more than two or three days, because the new deadline presses him. As a result, whatever his activity in the forest rubber, the native, due to the many displacements which are imposed on him, sees the major part of his time absorbed by the rubber harvest."
