1. Berthold Laufer, in his workSino-Iranica, 1919, makes a point of great culture-historical interest about the “fundamental diversity between East-Asiatic and Mediterranean civilizations — there hemp, and here flax, as material for clothing” (p. 293). In a footnote he says that he hopes to demonstrate in a subsequent study that hemp had been cultivated by the Indo-Chinese nations, especially the Chinese and Tibetans, in a prehistoric age. However, no such paper seems to have been actually published by him.
