THE PRODUCTION OF TANBARK.CENTERS OF THE INDUSTRY. The Santa Cruz district has been, from the first, one of the mostimportant sources of tanbark, because the tanneries at Santa Cruz,San Jose, Santa Clara, and Redwood City could be supplied bywagons direct from the woods, and this obviated long and costlyshipment by rail or water. Seventy-five per cent of the originalstand has been peeled, but recently second-growth trees have begunto furnish a bark which is acceptable to tanners.

This region hasfurnished probably more bark than all others put together, but 45per cent of the stand has been peeled now and a considerable portionof the remainder is, under present conditions, too inaccessible to beof value. The stand in the Santa Lucia Mountain region, along thecoast in Monterey County, which, though of excellent quality, wasnever large, is now almost exhausted. In the isolated Santa Bar-bara district and in the Sierra Nevada territory the trees are few andscattered. The most extensive bodies of virgin tanbark oak now are in thenorth—in northern Mendocino and Humboldt Counties—and becauseof accessibility to shipping the main sources of supply are in the coastregion of Mendocino, southern Humboldt, and, to some extent,Sonoma Counties in California, and in sout
