11. Footprints in the Coal Rocks of Westmoreland Co., Pennsyl- 
vania; by A. T. Kine.*—About 27 miles from this town, (Greens- 
burgh,) on the summit of Chestnut ridge, one of the principal axes of 
elevation of the Alleghany range, are numerous imprints, which are 
yery anomalous and remarkable. The greater number have much re- 
semblance to the tracks of cloven-footed ruminant mammals. They 
are of various sizes, and differ from most living types, in having had 
heel-like prominences, which made impressions from 1 to 2 inches 
behind the main tracks. 
The length of the largest track, including the posterior impressions, 
is 8 inches, and the breadth 5 inches. 
smaller ones vary from 44 to 54 inches in length, rea 
by 3$ to 44 in breadth. The general form is i 
ovoidal, the largest part being behind, as well as | ys 
the widest part of the cleft. The posterior im- fen] ‘ 
prints in the largest tracks, are each about the | 
size of a walnut. There are five large and eight : ; 
small tracks, in continuous lines, which are tol- — ( 
erably perfect, and many others which are much 
defaced. The imprints vary from 1} to 24 feet 
“Besides these, there are from four 
to six huge tracks of a different char- 
acter, and possibly Batrachian. They 
are in a continuous line, and each im- 
print is 13 inches long and 9 wide. 
There are 5 toes from 14 to 24 inches 
in length, and the second of them is | 
the longest. 
The average distance between the 
tracks is 3 feet 7 inches, with the ex- 
ception of the last two, which are 7 
feet apart. . This seems to indicate 
that there was at one time a track 
between, which has been since ob- 
literated, .
