The strong resemblance of the pipe figure (_l_) to the modern Sioux
calumets, made of catlinite or red pipe-stone from the famous quarry
in Southwestern Minnesota, has been spoken of as another objection
to the authenticity of the Stone. The form does not occur, as far
as the writer can learn, in any of the ancient rock-writings of the
eastern Algonkins, and no pipes of exactly the Sioux shape, which Mr.
E. A. Barber, of Philadelphia, considers the most modern of Indian
pipe-forms, have as yet been discovered in the ancient Delaware era,
nor even in the mounds.
On the other hand, the profile of the Sioux form itself could not
more closely correspond with the minute outline, which is too small,
perhaps, to be taken very strictly, than does the _profile_ of fig.
21--a pipe now in the Archæological Museum, at Salem, Mass., and found
by Dr. Putnam, in an ancient Indian grave near Beverly, Mass.

The other pipe figure on the stone might easily have been suggested by
the form from the mounds, with a slightly curved base (fig. 22), now in
the Peabody Museum at Cambridge, Mass., and discovered in a mound in
Ohio.
