374 MAN AND THE GLACIAL PERIOD. 



been found in similar deposits in western America. Peculiar 

 difficulties seem to surround the evidence brought forward 

 in support of such an assumption. We are told by Professor 

 Whitney that a stone mortar was " found standing upright, 

 and the pestle was in it, in its proper place, just as it had 

 been left by the owner." He fails, however, to explain how 

 this was brought about in a gravel deposit supposed to have 

 been laid down by great floods of water. So, when Mr. 

 Neale swears that he saw fifteen years ago in the same 

 gravels spear-heads a great deal larger than those known 

 to archaeologists, may we not ask whether reliance can be 

 placed on the memory of witnesses who testify to impossi- 

 bilities to justify conclusions that rest upon such testimony ? 

 I think we shall have to wait for further and better evi- 

 dence than this before we are called upon to admit that the 

 existence of the Tertiary man upon our Pacific coast has been 

 established.
