lumps being sold mostly for domestic purposes. The di-

road trestle. This brings you to a thin seam of eight inches 
that outcrops at the pier at southeast end of bridge 72, also 
in the lane opposite the spring house on the Squire place. 
This is the uppermost seam outcropping in this basin. Con- 
tinuing southeastwards, passing over a hundred feet of 
coarse red and yellow sandstone, containing a large number 
of calamites imbedded in the sandstone in a vertical position 
as they stood when growing, you will arrive at the great
