to the lower limestone and lower sandstone owing to the absence of ex- 

 posures to the west. Section IX shows at the bottom of the slope, 15 

 feet of limestones, the upper 5 feet of which is thin bedded and contains 

 fossils similar to the lower limestone in section I, except that the bryozoa 

 are more conspicuous in the latter. The lower ten feet have a striking 

 resemblance to the Mitchell limestone (oolite) both in appearance and 

 fossil content, while between the two there is a thin intercalation of sand- 

 stone which is possibly the lower sandstone. The level of the rocks corre- 

 sponds to the dip and thickness of the formation, but it is possible that the 

 whole thickness belongs to either the Solsberry or Mitchell.
