228 IMPLEMENTS MADE OF BONE. 



with one end ground to a sharp point; while Fig. 17 has been worked over 

 the entire surface and is pointed at each end. These specimens were col- 

 lected on the mainland. Fig. 104 represents a long pointed implement from 

 the island of San Clemente (P. M. 13533). - 



Figs 18 to 21, Plate XI, inclusive, are taken from specimens found at 

 Dos Pueblos and La Patera, and represent other forms of perforators. They 

 are all more or less worked fragments of long bones of mammals and birds, 

 with more or less well-defined points. Fig. 18 is cylindrical, tapering, and 

 worked over its entire surface. The fragment is too small to determine any- 

 thing concerning it. Fig. 19 is identical with the larger bone awls wherever 

 found. Jones, in his work on the Southern Indians,* figures a similar speci- 

 men, of which he writes: "It is made of a deer's tibia, and is 7^ inches in 

 length." Similar specimens are in the Peabody Museum from the Swiss Lakes 

 and other places. Fig. 1 9 was longer in its entire condition than now, as 

 the base is broken off abruptly. The surface is much decayed, but the 

 specimen appears to have been very carefully polished over its entire surface. 

 Similar perforators of bone are not uncommon in the Atlantic States, espe- 

 cially in the shellheaps on the sea-coast, and many of like character have 

 been found in the burial-mounds of the South and West. Fig. 20 is a frag- 

 ment of a bone implement similar to Figs. 13 and 14, except that it is 

 cylindrical. The entire surface has been worked with great care and 

 gradually brought to a point, as in Fig. 13. • Fig. 21 is a fragment of an 

 implement similar to Fig. 19. 



In most collections of implements or weapons, be they of stone or 

 bone, there will be some specimens of an indefinite character; and it is not 

 surprising that articles of curious shapes, and others of no apparent use, 

 should occur in the graves at Dos Pueblos. Figs. 22 and 23, of Plate 

 XI, are examples of this kind, and consist of masses of bone which have 

 been cut and ground down as shown by the figures. Figs. 24 and 25 

 are probably mouth-pieces used in connection with the ponderous smok- 

 ing-pipes of stone, already described, and are simply the hollow bones of 

 birds.
