Excerpt from Canaigre, a Potential Domestic Source of Tannin: Production Research Report No. 28Around 1925 the United States produced more than half of the vegetable tannin that it consumed in leather manufacture. Most of it was extracted from wood of the American chestnut tree and from oak bark. These sources now have been almost exhausted. Except for a very small quantity of tannin extracted from hemlock bark in the Pacific Northwest, the industrial needs of the United States for tannin must now be supplied through imports from foreign sources.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
