 figur(^ rests on th(^ spot at which the excavation in the bank began; 

 here the art-bearing talus deposit covered the gncuss with a veneering 

 hardly more than a foot thick; its character and contents are shown in 

 figure 5. This is the first of the series of- crosscuts or transverse sec- 

 tions, and represents the front wall of the excavation within a foot 

 of the beginning of the trench. Partially shaped implements and 

 artificial refuse, which may have come from any part of the slopes 

 above, occur throughout tlie deposits at this point. Xear the surface 

 a leaf-sliajje blade of ordinary type was found, and at 15 inches in 

 depth three others, more or less perfect, together with typical turtle- 

 backs, were encountered.

The exploitation pits (plate v), intended to determine something of 

 the pi-obable nature and extent of the work to be undertaken, were dug 

 along the line of proposed excavation from the starting point in the 

 ravine to the top of the terrace. It was observed that in the lower 

 half the profile of the slope was convex, and that in the upper it was 

 slightly concave. The convexity of the lower part, from the first figure 

 leaning against the young tree to 20 feet beyond the third figure, is 

 due to accumulations of refuse along the lower margin of the quarries, 

 while the depression above (beyond the limit of the picture) is due to 

 the pits left along the quarry face when the site was abandoned. 



Continuing the excavation beyond the i)oint at which the first cross 

 section (figure 5) was taken, the art-bearing deposits became quite
