I2M^ A short distance farther west is the second 

 railroad cut at the base of which is a dark gray rather 

 massive sandstone. Fossils occur ij feet below the 

 top of this zone. 7i^= 7 iir

The average dip in this cut is about 3J°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.

I2N^ A little farther west and just beyond a farm- 

 house is the third railroad cut. At the base is a dark 

 gray massive sandstone. 4i-2^=4-iV

 in the accompanying picture of the northern side of 

 this cut is shown back of the three students. 33= 7-h

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, 15^ 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.

I2A^ In the northern part of Saratoga Springs to 

 the east of Broadway is a quarry of considerable size in 

 the Calciferous sandstone and from its base to a small 

 run partly covered ledges of this sandstone occur. 40=40
