Light colored shale above, 

 with dark graptolite layers below. 





















The basal portion includes some 













thin bands of limestone. At 69 













feet is a 3 inch layer with black 













pebbles.

Purple shale. The upper 10 

 feet is olive-gray, grading into the

many limestone bands up to 













6 inches thick.

This is a dark shale with many 

 small "fucoidal" markings, giving 

 it a mottled appearance. Only a 

 few thin bands of limestone pres- 

 ent. The upper 3 inches is a 

 breccia. 



The test hole shows that the bed exposed at Sterling Station 

 extends thus far in undiminished thickness. There is no noticeable 

 change also in the character of the ore. A sample of the drill core 

 was analyzed by E. Touceda with the following results :
