Notice of Geological Surveys. 127 



and for building were found in abundance. Where these are in 

 the vicinity of water carriage, they may become articles of com- 

 merce, otherwise their value is only local. The abandonment 

 of the survey will prevent those important results to science 

 which were reasonably anticipated — except what may be yet de- 

 rived from materials in the possession of the geologists ; and we 

 hope these may yet be digested in some form to connect in regu- 

 lar continuity and system the rock formations of Ohio with those 

 of all the neighboring states where surveys have been underta- 

 ken. In the present report is given the geological structure of 

 eleven counties in different portions of the state, viz. Adams and 

 Athens, on the south on the Ohio river, Butler in the southwest, 

 Wood in the north. Portage and Trumbull in the northeast, and 

 Crawford, Licking, Muskingum, Tuscarawas, and Hocking, more 

 centrally. 



Local and general sections of the strata, with particular litho- 

 logical descriptions of the rocks, are given. There are a few 

 figures of organic remains, and we are constantly met with the 

 deficiency of characteristic specific catalogues of the fossils so 

 indispensable to a minute comparison of these with other forma- 

 tions. This deficiency would, we trust, have be^n supplied had 

 the survey been carried forward to its completion. Col. Whittle- 

 sey had collected materials towards the construction of a topo- 

 graphical as well as geological map. His observations upon the 

 variations of the magnetic needle and the altitude of places were 

 numerous, but must of course remain comparatively useless. His 

 plans and descriptions of a great number of the ancient mounds 

 we trust will be given to the public, for the intrinsic value they 

 possess in relation to the early history of this country, which is 

 now attracting more successful research than ever before. 



Dr. Locke has appended to his report the records of the ba- 

 rometer and thermometer at a great number of places. 



The zoological report of Dr. Kirtland is a very extended list 

 of the Fauna of the state in the department of " mammalia, birds, 

 reptiles, fishes, testacea, and Crustacea." He gives the scientific 

 term with the common name, the author of original description, 

 with very instructive and interesting notes on many of the spe- 

 cies. From some comparison of the mammalia and birds, the 

 resemblance appears to be very great to the list given in the last 

 New York report.
