“ The products of the Han valley are exclusively agricultural, consisting of cotton, wheat, rape seed, tobacco and various kinds of beans. Vegetable tallow is also exported in large quantities from this part of Hu-peh. Gold is found in the Han, but not in sufficient quantities to make working it more than barely remunerative. It is washed every winter from banks of coarse gravel, a little above I-chʽêng Hien, on which it is deposited by the river. Every winter the supply is exhausted by the washers, and every summer it is renewed by the river. ”
