DISTRIBUTION OF REPORTS. 



The first Report of G. C. Swallow, 1S54, was distributed 

 through the members of the Legislature and the State Geologist. 



The Reports 1855-71 and 1872, by authority of the Board of 

 Mines and Geology, were distributed by the State Geologist, 

 giving a certain number to each member of the Legislature and 

 members of Congress, one to each county clerk's office in the 

 State ; certain others to literary, scientific and collegiate institu- 

 tions in the State ; and copies also to State libraries, scientific 

 institutions and public libraries throughout the United States ; 

 certain number of copies also to the Geologist and his assistants 

 for general distribution in this and foreign countries. 



The Report of 1874 was distributed in part like the last, but 

 more generally ; the surplus copies were turned over to the State 

 Geologist for general distribution. These were distributed to per- 

 sons who by scientific repute could appreciate them, and copies 

 were freely given to parties all over the United States, and were 

 also sent into every civilized country on the globe.
