GEOLOGIC ATLAS OF THE UNITED STATES.

Under the plan adopted for the preparation of a geologic map of the United States the entire area is divided into small quadrangles, bounded by certain meridians and parallels, and these quadrangles, which number several thousand, are separately surveyed and mapped. The unit of survey is also the unit of publication, and the maps and description of each quadrangle are issued in the form of a folio. When all the folios are completed they will constitute a Geologic Atlas of the United States. A folio is designated by the name of the principal town or of a prominent natural feature within the quadrangle. It comprises topographic, geologic, economic, and structural maps of the quadrangle, and occasionally other illustrations, together with a general description.

The general distribution is through sale, at twenty-five cents each, except such as contain an unusual amount of matter, which are priced accordingly. Prepayment is required. The published folios are listed herewith.

b Postage stamps or checks can not be accepted.

The Kingston, Chattanooga, Pikes Peak, and Anthracite-Crested Butte folios are out of stock.
