non shailes, and Luther places the entire thickjiess of SaiHna shales 

 at 333 feet. The OA^erlying Bertie waterlime has a thickness of 



53 feet at the Buffalo Cement Cqi's quarry, while the Cobleskill 

 above varies from 7 to 9 feet near Buffalo to 12 feet at Falkirk 

 near Akron. 



Although gypsum beds of good quality no doubt occur below the 

 Bertie waterlime, no definite information can be obtained of such 

 deposits with the exception of the important ones at Akron and 

 those encountered in the wells of the Buft'alo Cement Co. at 

 Buffalo. 



Many gas wells drilled in Buffalo- and to the eashvard along the 

 escarpment report varying amounts of " gypseous shales," " gray 

 and white gypsum," etc., but careful examination of such records 

 fails to lead to any definite knowledge. They were all drilled by 

 churn drills in search of gas not gypsum, and little dependence 

 can be placed on the data relating to the latter, either as to its 

 quality, thickness or its depth from the surface. 



The occurrence of gypsum at Buffalo was well established by 

 the work of the Buffalo Cement Co. described by Ashburner.^ 



The Buffalo Cement Co. drilled a series of wells near the Alain 

 street crossing of the belt Hue in search for gas. Well no. i was 

 drilled to a depth oi 490 feet 6 inches with a diamond drill. Well 

 no. 2 was drilled 6 feet from well no. i with a 5^ jump drill to a 

 depth of 1305 feet. The core of well no. i is in the possession of 

 the Buffalo Academy of Natural Sciences. The record of no. 2 as 

 given by Ashburner is as follows :
