 fine and of uniform grain. The slope of the land at this point 

 is gentle and the floors can be made large without excessive 

 stripping. 



The second working is located west of the west mill, and the 

 stone obtained is a good grade of blue stone with buff and mixed 

 stone thruout the upper 15 feet of the bed. The line of parting 

 of the blue and the buff stone is very irregular and a large amount 

 of mixed stone results. The stripping at this point is heavier

than in the other opening, and the thickness of the bed of good 

 stone is consequently greater. The Mitchell limestone covers this 

 part of the valley and has protected the upper layers of the Oolitic 

 so that a comparatively level floor can be obtained. Two electric- 

 ally equipped derricks are used in this working, one of steel 

 and one of wooden construction. Purchased power is used with 

 both derricks. The quarry opening at this point is very large, 

 since this part of the working has been in continuous operation 

 for a long time. Much waste stone is in sight, and its disposal 

 is becoming a serious problem for the operators of the quarr3\
