Although of much less importance than the mastodon, a word may be added
as to the so-called alligator mound, more especially because the
alligator, owing to its southern habitat, is not likely to have been
known to the Mound-Builders of Ohio. That it may have been known to them
either through travel or hearsay is of course possible. A copy of the
mound from the "Ancient Monuments" is subjoined.
The alligator mound was described under this name for no other reason
than because it was known in the vicinity as such, this designation
having been adopted by Squier and Davis, as they frankly say, "for want
of a better," adding "although the figure bears as close a resemblance
to the lizard as any other reptile." (Ancient Monuments, p. 99.)
In truth it bears a superficial likeness to almost any long-tailed
animal which has the power of curling its tail--which, the alligator has
not--as, for instance, the opossum. It is, however, the merest
guess-work to attempt to confine its resemblances to any particular
animal. Nevertheless recent writers have described this as the
"alligator mound" without suggesting a word of doubt as to its want of
positive resemblance to that saurian.
