_To the Editor of the Bucks County "Intelligencer"_: The discussion in your paper about the so-called "Lenape Stone," in which my name has incidentally been introduced, leads me to address you a few lines on some archæological points, especially on the methods of distinguishing genuine from fabricated specimens. I shall only refer to the Lenape Stone by way of illustration. It was first shown to me by Professor Lewis, and after a careful inspection I pronounced it a modern piece of work, which opinion has been substantiated by later observers. My opinion was based, first, on the design, and secondly, on the execution. It may be laid down as a rule, holding good in all aboriginal designs of the Eastern United States, that no lines indicating either shading or rounding are found on figures of pure native origin. Every line was significant, and nothing was done for affect. Grouping was also unknown, and any such triple arrangement as the brute, the human, and the divine groups, standing in immediate relation to each other and forming parts of a picture, as appears on the Lenape Stone, was as far above aboriginal æsthetic conceptions as the Sistine Madonna would be above the execution of a sign-painter. Certain artistic details, as the lightnings shooting in various directions from a central point (as from the hand of Jove), were also unknown to the art notions of the red race. The treatment of the sun as a face, with rays shooting from it, I also consider foreign to the pictography of the Delaware Indians, nor have I yet seen any specimens proved to be of their manufacture that present it. It is found, indeed, in Chippeway pictography, but there only in late examples.
