In answer to your request, I put on paper a few thoughts in relation to the carved gorget of slate said to have been found in Bucks Co., Penna. It is needless to say that I have examined the stone with great care; for if it is a work of prehistoric times in America, it is a specimen of very great archæological interest. The first impression I received was that it was probably a fraud. This was of course natural, after having seen several gorgets with figures carved upon them which were unquestionable frauds. I therefore first of all examined the stone, and was sorry to find that it had been so much cleaned, and rubbed, and scrubbed, and probably oiled, that no evidence could be derived from the character of the lines cut upon the surface of the stone, or from the stone itself, bearing upon its antiquity. So far as the testimony of the stone itself is concerned, the lines may have been cut within a few weeks or many years ago. Throwing out of consideration all the facts you have given me in relation to the history of the stone as known to you, I am left with the character of the carvings alone upon which to draw conclusions. From a study of these I get the following results: 1st. The person who carved the stone must have been familiar with the appearance of an elephant or mammoth, either from having seen one or the other in life or represented in pictures. There is too much expression given to the details of outline of forehead, curve of back and belly, and position of the legs, representing the animal as walking, to be the work of one who only knew the animal from a general description handed down by tradition. 2d. Most of the other figures on both sides of the stone are of a character common to Indian picture-writing, but there are a few which, like the "mammoth," show an appreciation of details or ideas unlike any I can recall in Indian picture-writings. Take, for example, the fish on the edge of the small piece, and the long eel-like figure by the side of the bird--each of these have a few hair-lines drawn from the back as if to represent the rays of fins, in order to impress the character of a fish, although the rays are out of natural position. The figure of a man on his back under the foot of the "mammoth" is not drawn in the usual conventional manner, like the figure of the man with the bow. 3d. The idea of the heavens, conveyed by the figures of stars, moon, and sun, is probably not an unusual way of representing the sky or the heavens, but the mass of crossed lines near the sun, which are supposed to represent lightning, seems to me to be more the conventional symbol of the white man than the Indian. Considering all these points I draw these conclusions:
