Administration. — Under this act Prof. Edward Hitchcock was 

 placed in charge ol' the survey. He was assisted by Albert D. Hager, 

 and his sons, Edward Hitchcock and Charles H. Hitchcock, the same 

 being appointed Avith the approbation of the governor. 



This survey, like its predecessor, had no connection with any other 

 institution and was dependent upon direct appropriations for its 

 sustenance. The entire expense during the four years of its existence 

 amounted to but $4,000, of which $2,542.65 was for salaries and 

 $1,457.35 for traveling expenses and freight. Doctor Hitchcock, 

 himself, received no salary except in 1859 and 1860, in which years 

 it would appear he received $300 and $266.67, respectively. The 

 others received sums varying from $131 to $333.95, as shown in the 

 statement on page 504. 



Under Hitchcock's administration the work of exploration was 

 begun in the spring of 1857. The main objects which he announced 

 as to be accomplished were: First, to gain such a know^ledge of 

 the solid rocks of the State as to be able to delineate therii upon 

 maps and sections ; second, to study the loose deposits lying upon the 

 solid rocks and trace out the changes which the surface of tlie State 

 had undergone; third, to collect, arrange, and name specimens of 

 rocks, minerals, and fossils from every part of the State with a view 

 to forming a State cabinet ; fourth, to obtain a full collection for the. 

 cabinet of specimens valuable in an economic point of view; and 

 fifth, to identify tlie juetamorphosed rocks of the State with those 

 which have not been thus changed. 



The work of measuring sections, collecting specimens, tracing out 

 the formations, and collecting statistics from mines and quarries 

 devolved mainly upon A. D. Hager and C. H. Hitchcock, Mr. Hagei- 

 giving special attention to the economic geology, while Mr. Hitch- 

 cock paid especial attention to the superficial deposits. The survey 

 was assisted in its paleontological work by James Hall, of Albany, 

 New York. 



Puhlications and their distribution . — A final report of the survey 

 under Hitchcock appeared under date of 1859 and 1861 in the 

 form of two quarto volumes of 982 pages, with 30 full-pnge plates 

 and a colored geological map of the State. It cornprised a report on 

 the scientific geology of the State, which was the joint work of Doctor 

 Hitchcock and his assistants: second, a report on the economic 

 geology, by A. D. Hager: third, a report on the chemistry of the 

 survey, by Charles H. Hitchcock; fourth, a catalogue of 2,800 speci- 

 mens of rocks and 370 minerals, besides several hundred specimens of 

 organic remains, which had been arranged, ticketed, named, and dis- 

 played in the State cabinet; and, fifth, a report by Eev. S. M. Hall on
