The Geologic Atlas of she United States is the final form of publication of the topographic and 
geologic maps. 
ultimately to cover the entire 
country. 
The atlas is issued in parts, progressively as the surveys are extended, and is designed 
Under the plan adopted the entire area of the country is divided into small rectangular districts, 
bounded by certain meridians 
and parallels. 
The unit of survey is also the unit of publication, and 
the maps and descriptions of each rectangular district are issued as a folio of the Geologic Atlas. 
Each folio contains topographic, geologic, economic, and structural maps, together with textual 
descriptions and explanations, and is designated by the name of a principal town or of a prominent 
natural feature within the district. 
Two forms of issue have been adopted: A library edition, bound between heavy paper covers 
and stitched; and a field edition, similarly bound, but unstitched. 
Under the law a copy of each folio is sent to certain public libraries and educational institu- 
tions. The remainder are sold at 25 cents each, except such as contain an unusual amount of matter, 
which are priced accordingly. Prepayment is obligatory. The folios ready for distribution are listed
