MAPS AND ATIiASES. 



Topographic map of the United States. 



The map is published in atlas sheets, each sheet representing a 

 small quadrangular district. The mapped areas are widely scattered, 

 nearly every State being represented. About 1,100 sheets have 

 been engraved and printed. The maps of California are catalogued 

 in Part VI of this Bibliography. 



The map sheets represent a great variety of topographic features, 

 and with the aid of descriptive text they can be used to illustrate 

 topographic forms. The first three folios have been issued, viz. : 



1. Physiographic types, by Henry Gannett. 1898. Folio. Four 

 pages of descriptive text and the following topographic sheets : Fargo 

 (N. Dak.-Minn.), a region in youth; Charleston (W. Va.), a region 

 in maturity; Caldwell (Ivans.), a region in old age; Palmyra 

 (Va.), a rejuvenated region; Mount Shasta (Cal.), a young vol- 

 canic mountain; Eagle (Wis.), moraines; Sun Prairie (Wis.), 

 drumlins ; Donaldsonville (La.), river flood plains; Boothbay 

 (Me.), a fiord coast; Atlantic City (N. J.), a barrier-beach coast. 



2. Physiographic types, by Henry Gannett. 1900. Folio. Eleven 

 pages of descriptive text and the following topographic sheets ; Nor- 

 folk (Va.-N. C), a coast swamp; Marshall (Mo.), a graded river; 

 Lexington (Neb.), an overloaded stream; Harrisburg (Pa.), Ap-
