I met with several stones today that had the appearance of wood first carbonated and then petrefyed by the water of the river, which I have discovered has that effect on many vegitable substances when exposed to it's influence for a length of time. l believe it to be the stratas of Coal seen in those hills which causes the fire and birnt appearances frequently met with in this quarter. where those birnt appearances are to be seen in the face of the river bluffs, the coal is seldom seen, and when you meet with it in the neighbourhood of the stratas of birnt earth, the coal appears to be presisely at the same hight, and is nearly of the same thickness, togeter with the sand and a sulphurious substance which ususually accompanys it. there was a remarkable large beaver caught by one of the party last night. these anamals are now very abundant.
