II.-Subaerial Deposits of the Arid Region of North America

A Comparison of adobe with the loess of China forms the concluding part of this paper; but as no analyses of the Chinese deposit are known to me, a few analyses of the loess of the Mississippi Valley are inserted, not with the assumption, however, that the deposits bearing the same name in these two regions are identical. A comparison of this table with the one showing the composition of adobe is

I.-Subaerial Deposits of the Arid Region of North America

The subaërial deposits now accumulating in the arid portion of the United States may be divided into four classes: 1, Eolian Sands; 2, Talus Slopes; 3, Alluvial Cones; and 4, Calcareous Clays to which no specific name has been applied, but which, for reasons stated below, will be called “adobe” in this paper.

Instructions to rain-fall observers of U.S. Geological Survey

In the prosecution of the general "survey of the arid lands for purposes of irrigation," authorized by Congress to be undertaken by the U. S.
