GEOLOGIC ATLAS OF THE UNITED STATES. 



The Geologic Atlas of che United States is the tiual form of publication of the topographic and 

 geologic maps. The atlas is issued in parts, progressively as the surveys are extended, and is designed 

 ultimately 1o cover the entire country. 



Under the plan adopted the entire area of the country is divided into srnall rectangiilar districts 

 {designated mtadraiKjles), bounded by certain meridians and jiarallels. 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" and a "field edition." In both the 

 sheets are bound between heavy paper covers, but the library copies are permanently bound, while 

 the sheets and covers of the field copies are only temporarily wired together. 



Under the law a copy of each folio is sent to certain public libraries and educational institu- 

 tious. The remainder are sold at 25 cents eacli, except such as contain an unusual amount of matter, 

 which are priced accordingly. Prepayment is obligatory. The folios ready for distribution are listed 

 below.
