1890 Coca and its Therapeutic Application by Angelo Mariani

18 —

"This gathering of the Coca is just such an occasion for rejoicing for the natives of the valle5'^s, as reaping-time and harvests_are for our peasants. On the day when the gathering of the leaves is finished both sexes that have taken part in the work assemble and celebrate, in dances and libations, the pleasure they experience in having finished their labors." In 1851,the annual production of Bolivia was estimated to be more than 400,000 certos (600,000 kilogrammes) of Coca leaves, of which three-quarters came from the pro vince of Yungas.
