fought here, we would expect to discover large quantities of the 
utensils of war, and indeed we find this to be the case, as they 
abound in the vicinity of all of the greater ruins and many of 
the lesser. 
The arrowheads are particularly noticeable on ac- 
count of their delicacy, perfection, symmetry, diminu- ¢ 
tiveness (see Figure 51), and exquisite coloring. a 
hey surpass anything of the kind ever discovered 
in any other portion of the United States. In a single (Natura 
locality is frequently found the greatest variety of forms, 
and two are seldom picked up of the same material. Figures 
10 a, b, c, d, e, f, g, and h, Plate I., show some striking forms. 
We find them varying from less than half an inch in length to 
three inches. Sometimes we find a beautiful, transparent, amber- 
colored chalcedony specimen, while our next discovery may be a 
delicately fashioned point of obsidian. Here we discover a flesh- 
colored arrowhead made of agatized wood, while there we see 
another of a light pea-green tint. Red-jasper specimens seem to 
predominate, however, or are at least as numerous as those of 
flint, of which we find every shade of color. According to form, 
the arrowheads of this country may be classified into nine divis- 
ions, as follows: — 
(1.) Those which are leaf-shaped ; (2), those which are tri- 
angular ; (3), those which are indented at the base; (4), those 
which are stemmed ; (5), those which are barbed; (6), those 
which are beveled ; (7), those which are diamond-shaped ; (8), 
those which are awl-shaped ; and (9), those having the shape of 
a serpent’s head. Of course these forms are subject to modifica- 
tion, and often one runs into another. 
The materials are agate, jasper, chalcedony, flint, carnelian, 
quartz, sandstone, obsidian, or silicified and agatized wood. 
Among the relics of battles the barbed heads are the most com- 
mon, while the leaf-shaped varieties occur more numerously at 
a distance from the ruins on the plains, where they have been 
employed in the slaying of game. 
t will be immediately seen why this distinction in the selec- 
tion of missiles was made. The leaf-shaped or diamond heads 
could be readily withdrawn from the bodies of animals and used 
again, while the shaft of the barbed varieties could not be ex- 
tracted from the body of a human victim without leaving the 
point in the flesh to produce inflammation and probably death. 
The larger sizes may have been used on the points of lances or
