Administration. — In accordance with the resolution of 1830, Gov- 

 ernor Lincoln issued, on June 25 of that year, a commission to Prof. 

 Edward Hitchcock, of Amherst College, directing him to make a 

 survey of the Commonwealth in a manner contemplated by the 

 resolution and to perform such other duties relating thereto as might 

 be enjoined upon him and obeying such instructions, from time to 

 time, as he might receive from the proper authority. 



Professor Hitchcock seems to have entered promptly upon the 

 work and submitted his first report (pt. 1, Economical Geology) 

 under chite of January 1, 1832. This was a pamphlet of 70 pages, 

 in which was outlined his general plan of work, as well as the pre- 

 liminary report on the economic geology of the State. He an- 

 nounced his purpose to divide his final report into four parts, the 

 first the economical portion already mentioned; the second, topo- 

 graphical geology, or an account of the most interesting features of 

 the scenery; third, scientific geology, or an account of the rocks in 

 their relation to science; and, fourth, catalogues of native minerals, 

 botanical and zoological productions of the Commonwealth, this 

 latter being agreeable to the resolution of February 2, 1831. 



Realizing that a considerable period must elapse before the pre- 

 liminary report on economic geology could be completed, Doctor 

 Hitchcock announced the construction of a small map from such 

 materials as already- existed, upon which he delineated the various 

 kinds of rocks that he found prevailing in the State, the same being 

 shown by different colors and simple markings. To avoid confusion 

 he placed on this map such topography and geography as was abso- 

 lutely necessary, and employed but six colors for the rocks, although 

 announcing that more than 20 kinds were represented, his object 

 being " to simplify the map as to render it easily intelligible, while 

 it exhibits all that is important to the practical man as well as to 

 the scientific inquirer." 



So far as can be gleaned from available records no paid assistants 

 were employed in the strictly geological work, nor are there any 

 statements regarding the salaries. 



In the biological divisions of the survey, Hitchcock was assisted 

 by an able corps of specialists, including T. W. Harris on mammalia 

 and insects, Ebenezer Emmons on birds, S. C. H. Smith on reptiles, 

 J. V. C. Smith on fishes. T. A. Greene on marine shells, T. M. Earle
