46 PROCEEDINGS OF THE AMHERST MEETING 



In the closing years of the eighties and early years of the nineties the 

 writer had become interested in the problems presented by the geology of 

 the eastern Adirondacks, and when C. H. Smyth became established as 

 professor of geology at Hamilton College, in 1891, we two, being friends 

 of several years, formed an understanding that we would work in cooper- 

 ation on the east and west sides of this little known Preeambrian area. 

 After a year or two we learned that our old friend, Professor Gushing, 

 now established at Cleveland, was desirous of joining us in the work; so 

 that we informally agreed to share the area and continue our studies in 

 close cooperation, Professor Cushing taking the northern or northeastern 

 portion. Prof. James Hall, State Geologist, did what he could for all 

 three of us, but it is fair to state that an opportunity to work in the field 

 with an avenue of publication was what appealed to each of us, and no 

 one of the three allowed the matter of field expenses to stand in the way 

 of gathering observations. In the early work the contour maps, which 

 began to be available in the closing years of the last century, were lacking. 

 County atlases, with their great inaccuracies, were the best maps which 

 could be had. Almost inevitably the unit of the field-work was the town, 

 as the western "township" is officially called in Xew York State, and the 

 town or township maps were grouped by counties in the early reports. 

 As a result, we find Professor Cushing's first report to be one on Clinton 

 County, in the extreme northeast, and to contain a series of town or 

 township maps. 



While primarily engaged with the Preeambrian, no one of us in areal 

 mapping could escape being busied also with the early Paleozoic forma- 

 tions, and thus we see that Professor Cushing's next contribution relates 

 to the faults in the Cambro-Ordovician strata in Chazy township. As 

 time went by, his interest in the Cambrian and Ordovician sediments 

 grew very strong, and their subdivision in the circumferential area 

 around the Adirondack Preeambrian became one of his main lines of 

 research. The titles in his bibliography under the years 1908, 1909. 

 1910, 1911, and 1916, as well as important chapters in his New York 

 State bulletins on several quadrangles, attest his activity in these lines. 

 ^n his latest years the strain of field-work in the rough mountainous 

 country proved severe. His studies were therefore carried on in the more 

 open and flatter quadrangles along the Saint Lawrence and at Saratoga 

 Springs, and finally were devoted to stratigraphie problems in the vicinity 

 of Cleveland, extending from the Chagrin shale of the Upper Devonian 

 to the Sharon conglomerate at the base of the Pennsvlvanian. One of 

 these relating to the Berea grit was the subject of his very first paper. 

 His latest efforts were given to the preparation of the Cleveland folio. 

 Despite his valuable contributions on Paleozoic stratigraphy, Professor
