GEOLOGIC ATLAS OF THE UNITED STATES. 



The Geologic Atlas of the United States is the final 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 to cover the entire country. 



Under the plan adopted the entire area of the country is divided into small rectangular diatriets, 

 bounded by certain meridians and parallels. The unit of survey is also the unit of juihlication, 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 ?i&rrt/_i/ edition, bound between heavy paper covers 

 and stitched; and njield edition, similarly bound, but unstitched. 



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

 tions. A limited number of copies are reserved for distribution to persons specially interested in the 

 region represented. This distribution ia at lirst gratuitous, but when the remaining number of copies 

 of any folio reaches a certain minimum a charge etiuivaleut to cost of publication will be made. In 

 such cases prepayment is obligatory. The folios ready for distribution are listed below.
