MODIFIED DRIFT OF THE LAKE DISTRICT. 133 
extensively worked for brick-making fifty years ago, appears from de- 
scription to belong in the same class with the foregoing. 
No deposits of this kind were heard of about the north end of Winni- 
piseogee lake from the Wiers to Melvin Village. The well of Mr. Stock- 
bridge, in the eastern part of this village, about 25 feet above the lake, 
showed 6 feet of till underlaid by 10 feet of clay, followed by 6 feet of 
water-worn gravel, which contained copious springs. Less than a mile 
to the south-east a well at J. Tate’s showed 8 feet of coarse till and then 
4 feet of clay, underlaid by coarse, water-worn gravel. Chas. H. Copp’s 
well, 400 feet farther south-east, showed 4 feet of coarse till, underlaid 
by 23 feet of fine, stratified blue clay, beneath which ro 
water came in abundantly from a thin layer of gravel a A 
which rested on aledge. The former is about 30 and = 8 iia
