shales is somewhat indefinite because no samples were saved 
from between 469 and 580 feet, a thickness of 121 feet. 
In the vicinity of Baldwinsville, 1 1 miles N. W. of Syracuse, 
where natural gas has been obtained in large quantities, a num- 
ber of wells have been drilled. A set of samples from the 
Talmage well, one mile south of Baldwinsville, was furnished 
me by Mr. C. Pierce, of the Pierce, Butler and Pierce Manu- 
facturing Co., of Syracuse, which has been actively engaged in 
exploring this gas territory.
