Administration. — Under this law Arthur Winslow was appointed 

 State geologist. He was assisted by Prof. H. A. "Wheeler, Frank L. 

 Nason, Paul Schweitzer, G. E. Ladd, Hiram Philips, Erasmus Ha- 

 worth, J. E. Todd, and Charles R. Keyes. These assistants were 

 appointed by the State geologist with the approval of the board. 

 The salary of the State geologist was fixed as before at $3,000 a year 

 and that of his chief assistants not to exceed $1,800 ti year, other 

 necessary assistants receiving amounts not exceeding $5 a day. 



Under Winslow's administration the plan of woi-k adopted was 



(1) to prepare a series of monographic reports u})on separate sub- 

 jects, those of economic importance received first consideration; 



(2) to prepare successively a series of detailed maps of different 

 portions of tlie State to be accompanied with special reports con- 

 taining descriptive details. The subjects undertaken in pursuance 

 of this course were: 



1. Lead and zinc deposits; 2, the coal and coal regions; 3, the 

 cla5'^s; 4. the iron ores; 5, the mineral waters; G, the building stones 

 and crystalline rocks; 7, the Quaternary, or, more exactly, the glacial 

 geology; 8, the paleontology; J), hypsometry; 10, general geological 

 mapping. 



The study of lead and zinc deposits was begun in cooperation with 

 the national survey. The work on coals was placed in the hands of 

 Prof. H. A. Wheeler; that of iron ores in those of Frank L. Nason. 

 Paul Schweitzer studied the mineral waters; G. E. Ladd and Hiram 

 Philips, the building stones. Crystalline rocks were .studied by 

 Erasmus Haworth, and field work for the preliminary report on the 

 glacial geology was carried on by J. E. Todd. An exhaustive review 

 of the paleontology of the State, by Charles P. Keyes, was also pre- 

 pared, and many data relating to hypsometry were collected and 

 tabulated. 



Winslow continued in the office as State geologist until 1804. when 

 he was succeeded by C. P. Keyes. In 1897 the management (?) of 

 the survey passed into the hands of J. A. Gallaher. E. P. Buckley 

 was appointed State geologist in 1001.
