notches in the side, towards the base, intended, no doubt, to 
assist in securing them to a shaft. The arrow-heads on Tablet 8, 
Case B 32, are believed to have been used for shooting fish. 
All the other specimens belong to the stemmed and barbed 
type.* It may be noticed that the typical stemmed American 
arrow-heads, such as those on Tablets 2, 3, 4, 11, 12, and 13, 
Case B 32, might almost be classed as triangular, with notches 
at the sides," the base of the stem extends so much on each 
side. The comparative absence of leaf-shaped spear-heads 
in the Surface series, such as those found in the Mounds (see 
specimens in Cases C 34 to C 36), is as worthy of notice, as is 
the almost total absence of Surface types of spear- and arrow- 
heads in the Mound series. 
Florida. 
Cases D 19 and H 20. 
D 19. 
Upon Tablets 8 and 10 are some objects made from shell, 
found in a shell-mound, Florida. Upon Tablet 8 is a disc 
of shell, two inches in diameter, with a central hole ; perhaps 
this object was intended to be worn as an ornament in a similar 
manner to the shell necklet from one of the Salomon Islands, 
in Case D 7. Upon Tablet 10 are two pendants made from 
the columella of some large marine shell. The fragments of 
shell rings, h, c, and d, upon Tablet 8, and the marine shells 
upon Tablet 9, all from New Mexico, are shown for com- 
parison. Some of the shells on Tablet 9 are in process of 
manufacture. In Case D 7 are some shell armlets, from New 
Guinea, which serve to illustrate the rings upon Tablet 9. 
H 20. 
No. 2 is a cooking vessel of coarse black ware, found in 
Florida. 
H 19. 
Upon Tablet i are fragments of pottery found in the State of 
Iowa.
