Under its terms all of the most valuable farm lands in the W' illamette Valley were taken up, and since the law applied equally to Washington Territory numerous claims were filed there, too.

Between 1870 and 1880 the growth is more marked. This period was influenced by the gold rush to the Inland Empire which began in the 6o's and was signalized by the opening of new farming areas in Eastern Oregon. Mention has already been made of the Grande
