576 WYMAN ON THE SHELL-HEAPS 
mens collected by Mr. Morse in his first visit to Crouch’s 
Cove, was the last molar from the lower jaw. The crown 
was somewhat worn, but the ridges were not all effaced; 
it was of small size, measuring 0.55 inch in length, and 
0.46 in breadth. The average size of eight specimens of 
the same molar in the black bear was, length 0.60 inch, 
breadth 0.47, while that of two specimens from the polar 
bear was, length 0.54 inch, breadth 0.45. The tooth 
from the shell-heaps, therefore, as regards size, more 
closely resembles the last-mentioned species, as it does 
also in the shape of the crown,—but it would be unsafe, 
from a single specimen of the molar in- question, to at- 
tempt to identify them. The former existence of the 
polar bear, on the coast of Maine, is rendered quite prob- 
able by the fact that the tusk of a walrus has actually 
been found at Gardiner.* Sir Charles Lyell obtained a 
portion of the cranium of another at Gay Head, Martha's 
Vineyard.¢ It was found by a fisherman who supposed 
that it had fallen from a cretaceous bed in the cliff above. 
Perhaps it may have been of a more recent date, and 4 a 
ape gatoad of the Great Auk. 
e presence of the bones of the dog might be account- 
ed for on the score of its being a domesticated animal, but 
the fact that they were not only found mingled with those 
of the edible kinds, but like them were broken up, sug- 
gests the probability of their having been used as food. 
We have not seen it mentioned, however, by any of the 
earlier writers, that such was the case along the coast, 
though it appears to have been otherwise with regard to 
some of the interior tribes as the Hurons. With them, 
game scarce, “venison was a luxury found only at
