Of the forty-eight triangular points, twenty-seven, or more than 
one-half, have the tips missing. Ten have the base and edges more or less 
straight, thirteen have convex edges, and twelve others have the edges 
incurved or concave. Twenty-five specimens have indented or concave 
bases. What seems to be an unfinished point of this triangular type, 
illustrated in figure 3, is a concavo-convex chip of chert with all the edges, 
on the side illustrated, trimmed off round. The tip is unfinished or possibly 
broken, and the base is indented as in some of the finished points. Prob- 
ably, however, it was useless as a projectile point on account of the curva- 
ture. Figure 4 illustrates a thin point with convex edges and straight 
base. An irregularly shaped point, with the base considerably worn, is 
seen in figure 5. Figure 6 shows a well-chipped point with convex edges 
and indented base; another, illustrated in figure 7, is one of the largest 
whole points. One of the best points, illustrated in figure 8, is about three- 
sixteenths inch thick, with both edges incurved and the base deeply indented, 
producing two prominent barbs. Four other points have similarly incurving 
edges and concave bases. 
The only specimen of a pentagonal shape is a large point, with the 
tip missing. 
Three points are stemmed or shouldered, but not barbed. A crude, 
thick, and possibly unfinished specimen shown in figure 9 is a flake left 
nearly in its original condition, except that it has a crudely chipped stem. 
Its crude appearance suggests that it may be a reject, the work of chipping 
having proceeded far enough to show that it would perhaps be useless 
as an arrow point. Another stemmed point, seen in figure 10, is thick and 
slightly asymmetrical, with an attenuated, delicate tip and concave base. 
Fourteen points are notched. Most of them appear to have been 
produced from triangular forms by notching the edges near the base. 
The specimen illustrated in figure 11 has shallow notches. The wide, 
shallow notches of the point, illustrated in figure 12, were made with a 
bevel in opposite directions, so that the cross-section of this part of the 
point is rhomboidal; two other points are notched similarly. The edges 
of the point illustrated in figure 13, which is almost as wide as long, are 
bevelled in opposite directions. Figure 14 shows a point where the bevelled 
edges extend only about half the length of the blade. Another point 
was found with the edges similarly bevelled in opposite directions. 
MANUFACTURE OF STONE POINTS FOR ARROWS 
That the manufacture of points for arrows was carried on here, is 
suggested by the abundance of chert chips. Most of the progressive 
steps in their manufacture can be illustrated by incomplete specimens, 
including chips and large pieces of chert with secondary working, and 
leaf-shaped forms showing a still further advance. 
BONE POINT FOR ARROW 
Only one of all the bone artifacts, found here, seems adapted for use 
as a point for an arrow. It is illustrated in Plate I, figure 15. This point 
is rhomboidal in cross-section near the tip. The broken basal end seems 
to have been wedge-shaped.
