the existence of the quartz-bearing stratum was first definitely 
settled, I collected from it a half peck, or such a matter, of quartz 
pieces. Among these appeared a group of specimens numbering 
adozen or more, which belonged to a type unknown to me at 
the time, The most finished implements of this shape have deli- 
cate, fragile edges formed by a single thin leaf of the quartz pro- 
longed beyond the mass of the object in a series of irregular, 
minute notches. Further exploration of the site, continued up 
to the present time, has, so for as observed, failed to unearth a 
single specimen of the same class elsewhere. Whether we 
assume these small articles to be natural productions or artificial 
ones, or whether again we hold them to be natural forms more 
or less modified by the hand of man, there is no escaping the 
conviction that the grouping together of these and other like 
objects is wholly the work of intention. Previous to the discov- 
ery here narrated, I had more than once or twice chanced upon 
bunches of specimens of a common figure, lying in separate hud- 
dles in the sand at the edge of the stratum, and apparently just 
Washed out of it. 
Upon another occasion I found in my daily budget a small 
cluster of rude triangular points, quite unfashioned, as I thought, 
and averaging about an inch and a fourth, or a half, in length, by 
three-fourths of an inch in width. These being at first supposed 
to be unwrought figures, were thrown out as such. However, 
Persistent recurrence of identical forms in the day’s yield 
‘ventually suggested a meaning of its own independent of the
