the western, or river, edge of the quartz deposit, and swept away 
all such products of man’s labor as were at that time exposed to 
its action. The operating forces having been exerted upon the 
west of the present terrace-bank, it follows that only the eastern 
edge of the stratum remains to us, the western border being cut 
and lost.

In finale, it is proper to reiterate the fact that the working 
hypothesis of the moment is one which the writer has been driven, 
in spite of preconceived notions, to adopt. All the internal evi- _ 
dence of the case, thus far elicited, harmonizes completely with 
the view enunciated, and with this view alone. The study here 
commenced is henceforth to be pursued along two distinct lines 
of investigation; one comprehending the dfift surfaces of the 
region, the other the objects exhumed. The latter, or purely 
archeological phase of the subject, remains to be more fully 
loped at some future time; but it may be stated in this place 
__ that the quartzes of the cache are to the last degree primitive in 
their general types and particular forms, and in their style of 
workmanship.
