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-jive cents each, except such as 
contain an unusual amount of matter, which are priced accordingly. Prepayment 
is required. The published folios are listed herewith.
