I did not learn that the coals seen in this section had been mined in 
this neighborhood. Farther east, in the cut at Glencoe Station, the lower 
seam of coal in the preceding section is found to be four feet thick, and 
twenty-eight feet above the bottom of the cut. The whole section at 
this point is as follows:

This lower cement limestone is approximately in the horizon of the Par-

The fall of McMahon Creek from Glencoe east is such that it exposes
