roughly wrought on one side, the other being left flat and 
smooth, recalling the implements of the Moustier Cavern, 
Dordogne, France (Fig. 2). This shell heap is probably one of 
the earlier class. A careful search along the entire section of 
pottery, and none was met with in digging. Two pieces upon 
the surface were probably from later Indians. Investigations 
at this spot, however, were not based upon enough excavations 
to give a final judgment upon the subject. 
._TWO SHELL HEAPS ON SALT RUN. 
Salt Run makes into Lake George about two miles south- 
west of where the St. John’s leaves the lake. On the right 
bank, going up, at a distance of about half a mile from the 
mouth, is a shell deposit some two hunderd yards in length — 
and one hundred yards in breadth, with a height of from four — 
to five feet on the water’s edge, increasing to a maximum of — 
ten feet somewhat beyond the middle toward the land. On 
the same side of Salt Run, about half a mile farther up, is a- 
deposit of shell presenting no irregularities of surface, though 
varying in depth at different points, owing to unevenness of 
ground upon which the deposit was made. 
EXCAVATION I. 
53x5x3% feet deep; after surface loam no pottery was met 
with. Fragment of bone awl at a depth of 34 feet. About | 
three feet down was found, within half a foot of the bottom of
