Rocky Mountains. 21 



entered after sunset a tall grove of elms and hickories; towards 

 which we were attracted by some unusual sounds. Direct- 

 ed by these, we at length* reached an open quadrangular 

 area of several acres, where the forest had been in part 

 cleared away, and much grass had sprung up. Here we

 the water's edge. 



Compact limestone appears here, in the bed of the Ohio, 

 and extends some distance in all directions. This limestone 

 has been used in paving the streets, for which purpose its 

 tabular fragments are placed on edge, a-s bricks are some- 

 times used in flagging. The formation of limestone, to which 

 this rock belongs, is one of great extent, occupying a large
