ON RECENTLY DISCOVERED DEPOSITS OF DIATOM- 
ACEOUS EARTH IN THE ADIRONDACKS, 
BY CHARLES F. COX. 
The construction of the new railroad (The Mohawk and 
Malone) in the Adirondack Mountains during the past year has 
led to the recognition, and, in some cases, the actual discovery, 
of extensive deposits of diatomaceous earth previously unknown 
to science. The deposits referred to, occur principally upon the 
bottoms of four small lakes, one of which is in the extreme 
southern part of Herkimer county, near the town of Hinckley, 
and the other three in the extreme northern part of the same 
county in Township No. 43. There are evidences of smaller 
deposits in the intervening country, particularly in certain rail- 
road cuttings, and, perhaps, in bogs and sink-holes which have 
been the cause of trouble in the construction of the road. The 
deposit near Hinckley has been known to the inhabitants of 
this region for a long time, and the pond in which it occurs has 
been called by them White Lead Lake. But specimens of this 
earth do not seem to have reached naturalists until very lately. 
The deposits in Township No, 438 appear to have been entirely 
unknown until the Mohawk and Malone Railroad was con- 
structed. They occur in Clear Lake, Roilly Pond, and in an 
apparently unnamed body of water near Big Crooked Lake, 
The deposits in sight at Hinckley has been estimated at 100,000 
cubic yards ; that at Clear Lake at about the same amount ;
