wrought by rude instruments. Some of the characters are like those 
upon the Dighton, Tiverton, and Portsmouth rocks, about which so 
much interest has been felt in the North of Europe. They are gener- 
ally outline figures of full size, cut into the rock from one half to one 
inch in depth and the same in breadth. They consist of the human 
form, quadrupeds, birds, reptiles, dots and lines, with the tracks or foot« 
prints of animals and birds 3 
It is to these footprints that I wish to direct your attention in particu- 
lar, as possessing some interest for the geologist, as well as the antiqua- 
rian. In many instances they are so well executed, and life-like, as to 
deceive the most experienced geologist; for example, the human foot- 
prints in the limestone near St. Louis, first figured and described by 
Mr. Schoolcraft,* which remained for many years a geological wonder, 
but were at last satisfactorily explained by Dr. Owen.t The Derry 
sandstone in Westmoreland County, Penn., with the supposed fossil 
footprints of birds and quadrupeds, described by Dr. King,t are of the 
same class of artificial tracks, and were correctly so considered by Mr. 
Lyell who examined them personally.§ | a see
