4 THE U. S. GEOLOGICAL SURVEY 



The original appropriation for this survey was only $5,000, 

 but this was increased by successive annual appropriations of 

 $io,ooo, $25,000, $50,000, $75,000, $115,000, $110,000, 

 $95,000, $65,000, $75,000 and $75,000, as well as by a specific 

 appropriation of $30,000 to complete maps and office work ; so 

 that the total cost of the survey amounted to $735,000 ex- 

 clusive of the cost of printing and engraving and of the ser- 

 vices of several officers detailed from the Army. 



3. Geographical and Geological Survey of the Rocky Moun- 

 tain Region. In 1867 the Smithsonian Institution began an 

 exploration of the Colorado River. This survey was later 

 recognized by Congress in a joint resolution, approved July 11, 

 1868 (15 Stat. L., 253), authorizing the Secretary of War "to 

 issue rations for twenty-five men of the expedition engaged in 

 the exploration of the river Colorado under direction of Pro- 

 fessor Powell, while engaged in that work." Additional ap- 

 propriations, $54,000 in all, were granted in 1870-73, the ex- 

 pedition still remaining under the control of the Smithsonian 

 Institution. On the completion of the survey of the Colorado 

 River, Powell was, by act of June 23, 1874 (18 Stat. L., 207), 

 authorized to continue the survey in Utah under the direction 

 of the Secretary of the Interior; and subsequent acts of ap- 

 propriation authorized the extension of the field of survey to 

 the "Rocky Mountain region." In all, the area surveyed was 

 67,000 square miles, embracing southern Wyoming, central 

 and southern Utah and adjacent portions of Nevada and Ari- 

 zona. This survey was primarily exploratory and geographi- 

 cal but, in addition to the triangulation of the whole region and 

 the establishment of the geodetic points, it included work in 

 topography, ethnology, geology, botany, paleontology and 

 kindred sciences. 



The results of the survey were not published in full, the 

 only printed documents produced being two brief reports in 

 1877 and 1878 by Powell.
