2 350 Dark red, rather arenaceous shale, 
which is slightly calcareous. Salina 
3 400 Somewhat darker red, argillaceous 
shales which are slightly calcareous. 
Mr. Hartnagel states that at this hori- 
zon the brine was strongest, 12^ per 
cent NaCl. Salina 
4 580 Very dark gray fine chips which effer- 
vesce strongly in cold HCL. Niagara 
5 650 Coarser chips, mostly dark gray, but 
some of them lighter colored. Effer- 
vescence not so strong in cold HCL as 
in the previous sample. Mr. Hart- 
nagel reported, at this horizon, the 
greatest flow of gas which burned with 
a flame about 4 feet high. Niagara 
6 700 Similar to the first sample of Niagara, 
Strong effervescence in cold HCL. Niagara 
7 q8o Mostly light red argillaceous or slightly 
arenaceous shale. Some greenish 
chips. Non-calcareous. Medina 
8 1016 Dark red arenaceous chips; fine grained 
sandstone. Medina 
9 1218 About the same as the preceding, but 
chips are finer. Mr. Hartnagel re- 
ported gas from this horizon. Medina 
10 1430 Mostly dark red sandstone chips; some 
argillaceous shale. Medina 
11 1665 Quite coarse dark red arenaceous chips 
from sandstone. Medina 
12 1930 Mostly greenish-gray arenaceous chips 
from fine grained sandstone; some blue Oswego 
argillaceous shale. sandstone 
The well was drilled 435 feet deeper, as far as the Hud- 
son formation, making a total depth of 2365 feet. Unfor- 
tunately samples were not saved from the Clinton forma- 
tion, so its thickness cannot be given in this section; but 
judging from neighboring wells it must have been reached 
at a depth of 75 + feet. 
The thickness of the formations in this well agrees very 
closely with that of the same formations in the neighbor- 
ing wells at Clyde and Seneca Falls as described by the 
writer ten years ago. In the Clyde well, 8 miles N. E. of 
Alloway, the Niagara and Clinton are 418 feet thick* and in
