244 REPORT OF NATIONAL MUSEUM, 1901. 



specimens shown in Plate 9, an upper tooth, is 11 inches in length, and 

 very massive. Mr. Lucas, observing the differences between the two 

 specimens shown in Plate 9 (the one being finely and the other coarsely 

 ribbed), expresses the opinion that they may possibly represent two 

 varieties of mammoth — El&phas primigenius and Elephas imperator, 

 the latter species, proposed by Leidy, not as yet having been gener- 

 ally accepted. 



Associated intimately with the flint implements in the spring were 

 bones of two or three buffalo, four or more deer, one elk, half a dozen 

 wolves, and one or more horses. These were a little more widely dis- 

 tributed than the flints, but were distinctly a spring deposit, and it is 

 not unlikely that their presence also was partly or wholly due to 

 human agency. 



STONE IMPLEMENTS. 



The implements found in the spring had been subjected to so much 

 disturbance before my arrival that the exact nature of the original 

 deposit could not be determined. They were in compact order, as if 

 dumped in a bod} T , but much the same result would have followed 

 from the casting in of single specimens or small lots at various times, 

 since all would settle to the deepest possible point in the spring basin, 

 the position and character of w r -hich has probably remained unchanged 

 for a long period. It is impossible to say whether or not the native 

 tribes ever took the trouble to excavate the basin, either for conven- 

 ience in using the water, to increase the flow in dry seasons, or to facili- 

 tate the introduction of the implements; but if the objects deposited 

 were, as we suppose, in the nature of offerings, the spring was a sacred 

 place and no one would venture to disturb it under any circumstances. 



It was noted that the remains of buffalo, deer, and wolf were inter- 

 mingled with the implements and that they were not associated as 

 though the animals had died on the spot, but rather as if the separate 

 bones or dismembered parts of the creatures had been thrown in with 

 the implements. 1 am inclined to the view that they were cast in as 

 offerings, since there seemed to be a very large and disproportionate 

 number of bones of one kind; for example, not fewer than twenty or 

 thirty of the large, straight leg bones of the deer were associated 

 directly with the flints. 



If statements coming from apparently reliable sources be correct, 

 more than half the deposit of implements had been removed before 

 my arrival. 1 obtained altogether, counting fragments and partially 

 shaped pieces, more than 800 specimens, not quite half a bushel, so 

 that there must have been at least a bushel (some say a barrel) of 

 implements in the original deposit, the number reaching somewhere 

 between 1,500 and 2,000. They include arrowheads, spear points, 

 knives, and unspecialized blades, besides some roughed-out forms and
