"My attention was first called to the subject by Dr. James Deane of Greenfield; who sent me some casts* of impression, on a red micaceous sandstone, brought from the south part of Montague, for flagging stones. Through the liberality of the same gentleman, I soon after obtained the specimens themselves, from which the casts were taken; and they are now deposited in the cabinet of Amherst College."
* The editor of this Journal was early indebted to Dr. Deane, for similar casts of these tracks.
