GEOLOGICiUL, AND NATURAL HISTORY SURVEYS. 308 



Sec. 4. Wlienever said survey shall be completed, a report of the same, ac- 

 companied by such maps and drawings as may be necessary to elucidate and ex- 

 emplify the same, shall be published under the direction of said State geologist. 

 Sec. 5. That, for the purpose of carrying into effect tlie provisions of this act, 

 the sum of $3,500 is hereby annually appropriated, to be expended under the 

 direction of the governor and council. 



Sec. 6. Tliis act shall take etfect from its passage. 

 Approved July 3, 1S68. 



This law remained in force throughout the existence of the survey. 

 N'o additional acts were passed, with the exception of one providing 

 for the publication of reports. The survey was not connected with 

 any other institution and was sustained wholly by annual appro- 

 priations, and continued uninterruptedly for 10 years. 



Administratwn. — Under the law given above C. H. Hitchcock was 

 appointed principal on September 8, 18G8, and continued in office 

 until the expiration of the work May 31, 1878. Various assistants 

 were appointed from time to time. J. H. Huntington was appointed 

 in 1869 and served more or less constantly until 1878, though doing 

 no field work after 1875. Warren Upham v»^as appointed in 1871 — 

 at first temporarily — and served until 1878, his special field of study 

 being the glacial drift and surface geology. He also attended to 

 drafting of the maps, plans, and illustrations. Dr. George W. Hawes 

 prepared the part of the final report pertaining to mineralogy and 

 lithology, being employed between two and three years in the work. 

 Other tem.porary assistants were Prof. George L. Vose, of the Massa- 

 chusetts Institute of Technology; Prof. Charles A. Seeley, of New 

 York, chemist; and Dr. A. M. Edwards, who studied diatoms. Prof. 

 Thomas Egleston, of Columbia College, commenced work on the 

 optical mineralogy in 1874, but was obliged to give it up because of 

 ill health. 



The salary of the State geologist was at the rate of $1,500 a year; 

 that of J. H. Huntington, $500 annually; and that of Warren Up- 

 ham, about $3 a day. George W. Hawes received $800 a year, this 

 amount being paid from appropriations for publishing the report. 

 The principal was himself connected with Dartmouth College, but 

 the college had no connection whatever with the survey. 



The methods of procedure employed by the survey are outlined be- 

 low. The State being located entirely upon crystalline rocks, the 

 methods employed were not exactly the same as those used in regions 

 of sedimentary deposits. A contour map upon a scale of 2i miles to 

 the inch was first prepared. The trigonometric stations were ob- 

 tained through the United States Coast Survey, the boundary survey 

 of 1842, various private survej'^s, and considerable special work. The 

 roads, villages, streams, and other fixed points were chiefly located 

 from county maps prepared shortly before the survey commenced.
