12M! A short distance farther west is the second ii 
railroad cut at the base of which is a dark gray rather 
massive sandstone. Fossils occur 14 feet below the 
top of this zone. 7 i= 7 fs

The average dip in this cut is about 34°W; but a dip of 5°S, 70° 
W was recorded. Some of the layers are somewhat shaly and the 
rock weathers to a rusty brown color.

A number of specimens of Lingulepis acuminata Con. 
were found in the rock, apparently thrown out of this cut. The 
greatest dip noted is 3° S 70° W;; but perhaps 2° is nearer the aver- 
age dip. | 
12B More than a mile north of Saratoga Springs on the Adiron- 
dack railroad is a cut near the Davis brickyard known as the Lime 
Kiln cut. The rock is a light gray calcareous sandstone, 154 feet 
of which are shown in the cut. A few rods to the south the rock 
was formerly quarried to some extent and then burned for lime. 
The rocks forming the upper part of the cut contain fossils as 
Cryptozoon and trilobites and in one thin layer numerous 
specimens of Lingulepis acuminata Con. were found.
