Report of the State Geologist. 



Mr. D. D. Luther, who has already contributed a valuable report upon the 

 Livonia salt shaft and the products of the salt field generally, has reported 

 upon the general and economic geology of Onondaga county, and has also 

 been working upon the stratigraphic relations of the Portage sandstones in 

 the Naples valley, and along the line of their outcrop from Seneca lake to 

 Lake Erie. 



Dr. Heinrich Ries of Columbia College, has made an elaborate investiga- 

 tion of the geology and economic resources of Orange county, N. Y., 

 contributing much to our previous knowledge of the distribution of the rock 

 formations in that part of the State. Professor I. P. Bishop, of the State 

 Normal School at Buffalo, has investigated the structural and economic 

 geology of Erie county, and has communicated a valuable map showing 

 the distribution of the geologic formations, and the localities of oil and 

 gas, with other economic resources of that county. 



Professor C. H. Smyth, Jr., of Hamilton College, has been engaged in 

 the stud\' of the rock formations occupying parts of the counties of St. 

 Lawrence, Lewis and Jefferson, and has communicated a report upon the 

 same. Professor Smyth has also made a report on the talc industry of St. 

 Lawrence county, which will form an important addition to our knowledge 

 of the economic resources of the State. Professor H. P. Cushing, formerly 

 of Columbia College, now of Adelbert College, Ohio, has made an examination 

 of Clinton county, and the adjacent portions of Franklin, and will furnish 

 a report upon the topography and structural geology of that region. 



Professor J. F. Kemp, of Columbia College, has contimied his investiga- 

 tions of the geology and economic resources of Essex county, and this 

 report, accompanied by maps and diagrams, will form a part of the present 

 report of the State Geologist. 



The following synopses of these several reports and contributions will 

 give an idea of the nature and results of the investigations carried on in this 

 department.
