GEOLOGY OF VERMONT. 



Geological Survey. 



In my Preface to the Natural, Civil and 

 Statistical History of Vermont, it was stated 

 that Chapter VIII, Part I., remained to be 

 ■written, after a Geological Survey of the 

 state should be effected. Little did I then 

 think that ten years would be suffered to 

 pass away, and so desirable a work remain 

 unperformed. But such is the fact ; and 

 I am, therefore, yet under no obligation to 

 redeem my pledge, to wi-ite that chapter. 

 But since, within those ten years, a Geo- 

 logical Survey of tlie state was begun, and 

 since, through tliat beginning, and other 

 means, important geological facts have been 

 brought to light, I shall here give a brief 

 • history of the labors, which have been per- 

 formed, and a brief sketch of the knowledge 

 of our geology which has been acquired. 



The first state Geological Survey, prose- 

 cuted under legislative authority, was, I 

 think, authorized by North Carolina, in 

 1823. In 1824, the legislature of South 

 Carolina authorized a geological survey ; 

 and in 1830 provision was made for a geo- 

 logical survey of Massachusetts, under the 



atithority of that state. The execution of 

 the survey of Massachusetts was committed 

 to Professor, (now President), Hitchcock, 

 of Amherst College, and was prosecuted 

 with so much ability and success, that 

 most of the other states followed the exam- 

 ple, and authorized surveys. 



In the execution of these surveys, and in 

 the publication of the results, the state of 

 New York has, by far, outdone any of the 

 other states. The plan of the New York 

 survey embraced, not only the Geology and 

 jMineralogy of the state, but also the Botany 

 and Zoology ; and ample provision was 

 made for carrying out that plan. The 

 corps of surveyors embraced four distin- 

 guished geologists, one mineralogist, one 

 palaeontologist, one botanist and one zoolo- 

 gist, with their respective assistants. Ar- 

 rangements were made for commencing the 

 work in 1836, and, after five years of in- 

 cessant labor, in 1812, several volumes of 

 the Final Reports were in readiness for pub- 

 lication, which, with other volumes after- 

 wards prepared, have since been published. 

 These reports are published in large quarto 

 form, on excellent paper, and fully illus-
