DESCRIPTION OF MATERIAL PASSED THROUGH. below 



surface. 



Argillaceous Limestone to 



Limestone with some Chert; upper part light- 

 gray, the lower of a still lighter color 



Mostly a light-gray or blue Clay 



Dark Clay 



Blue Clay alternating with thin Limestone layers 

 Blue and drab Limestone, with probably some 



Magnesian layers at 1 139 ft., to 



Cream-colored Magnesian Limestone at 



Light-blue cherty Limestone, with salt water al 



extending to 



Light-colored Limestone from 1225 to 



Dark Limestone to 



Light-drab cherty Limestone to 



Yellowish-gray Limestone to 



Dark Limestone from 1402 to 



Light-colored Limestone 



Mostly pure white Sandstone, the upper portion 

 soft and consisting of pure, clear and rounded 

 grains, and contains sulphurous water. The 

 lower portion is somewhat brown. Extends 



from 1 45 2 ft. to 



Buff-brown and drab-cherty Limestone to 



Buff and brown Magnesian Limestone, some of 



t cherty, to 



Buff and drab cherty Magnesian Limestone, to. . 



Hard and mostly pure Sandstone, with some 



Limestone beds with Chert, buff and brown or 



reddish-gray, to 



Limestone" and Chert — colors buff, drab, and 

 gray. The Chert beds include probably one- 

 half the entire series from 21S4 to 



No Chert from 2671 to 2735. Sand often abun- 

 dant to 



Mostly Sandstone with a little Lime in the upper 



part to 



Limestone, mostly free from Chert and Sand, to 



Sandstone, upper portion dirty, middle blue, and 



the lower part is reddish-gray with a blue tinge 



Dark Magnesian Slate to 



Yellowish-drab or gray Magnesian Limestone 

 hard, and contains but little Sand. The lower 

 66 ft. is thin-bedded dirty-reddish-gray, with 



some sandy beds, to 



Mostly hard thin-bedded Sandstone, dark olive- 

 gray in color— under the magnifying-glass it 

 seems to be formed of white and black grains— 



to 



Sand and Limestone to 



Brown Sandstone near upper part, the lower 

 mostly Granite— the lower 40 ft. is a hard red 

 rock, and is certainly powdered Granite, for 

 some of the grains are red Quartz or Feld 

 spar — to
