148 PREHISTORIC FISHING. 



Fig. 233 (on page 147). This harpoon-head, of very old appearance, has 

 lost its point and is broken at the lower part, which shows a roughly executed 

 perforation. It was probably detachable. Obtained by Mr. Ball from the lower 

 mammalian layer of an ancient rock-shelter in Atka Island, Alaska. 



Fig. 234 (on page 147). A larger specimen, in a better state of preservation, 

 but likewise lacking its point. The base forms an edge like that of a blunt chisel, 

 and the hole is carefully drilled. On both sides a cavity of elongated oval form 

 is worked out between the hole and the barb. This dart, it appears, separated 

 from the shaft, when used. It was found by Mr. Dall in the lower mammalian 

 layer at Port Moller, Peninsula of Aliaska. 



Fig. 235 (on page 147). This diminutive dart-head, of excellent workman- 

 ship and fresh appearance, probably was not designed for practical use, but may 

 have served as the armature of a toy-harpoon, by means of which a juvenile 

 hunter qualified himself for the more serious work of later years. The point is 

 rounded and polished like the whole object. The base of the barb shows a 

 straight ornamental incision, and below the blunt point a small nick has been cut 

 out. It is one of the specimens collected by Mr. Dall. He discovered it in the 

 upper fish-bone layer in a cave of Amaknak Island, Captain's Bay, Unalashka.

FIGS. 236 aud 237. Bone harpoou-heads. 



Fig. 236. A bone harpoon-head resembling in general character the speci- 

 mens just described, but derived from the Atlantic coast-region. It is probably 

 made from the leg-bone of a deer. One side shows the natural rounded surface 

 of the bone, the other its internal cavity. Thickness about three-eighths of an 

 inch. This dart was found in 1882 by Mr. A. T. Gramage in a shell-heap on 

 Hodgdon's Island, Damariscotta River, Maine, and presented by him to the 

 Peabody Museum (No. 29279). 



Fig. 237. This harpoon-head has lost its upper part, but probably termi-
