A Report on Washington Territory

by William Henry Ruffner

SOILS.

Soils all fertile.The arable soils of Washington Territory, so far as I could see, or otherwise learn, may be classified as follows, to wit: a. Humus; b. Alluvium; c. Drift; d. Loam; e. Basalt.

a. Humus. In West Washington the whole country is top-dressed with vegetable mould, derived obviously from the heavy growth which has covered the surface for ages. Of course there are bare spots, and where the growth has been light, the top-dressing is thin; but the mountain sides, the hills, and notably the low grounds, are overlaid from one to ten inches, and often much more, with this vegetable mould.
