Mr. Hayes makes the objection that he has neverseen the original limestone unaltered. I have so seen it, butonly in one instance. It is indeed rare, and it would be awonder if it were not. In proportion as the drainage-outlets(springs) of that early day assumed lower levels, due to thedeepening of the valley-floors, the limestone outcrops of thehigher points escaped impregnation, and, being left high and. 600 CLINTON RED FOSSIL-ORE IN LOOKOUT MOUNTAIN. -In-Coiupression-
