micaceous sandstone, however, exhibits great clusters of culmariæ (striaticulmis of Martyn), almost ancipitally compressed, and with the striatures very fine. Here the calcareous rock beneath the micaceous sandstone exhibits masses of terebratulites, some of which are very minute, but in great quantities. Near to the precipitous termination of Grant's Hill, and in several other contiguous places, the sandstone appears to have been disintegrated with violence, and the angular fragments again to have been cemented by a stalactitial deposition of calcareous spar, of a fibrous {20} texture, almost similar to Arragonite. Seams of fibrous gypsum, possessing a silky lustre, have also been discovered in this vicinity.
In the course of this ramble I found abundance of the Monarda hirsuta, which as well as M. ciliata, do not much resemble the legitimate species of the genus.

21ST.] To-day I left Pittsburgh in a skiff, which I purchased for six dollars, in order to proceed down the Ohio. I was fortunate enough to meet with a young man who had been accustomed to the management of a boat, and
