174 PEEFOEATED STONES. 



in each about 1^ inches in diameter. In the larger specimen, which is 2\ 

 inches thick by 3 J in diameter, the perforation was made by boring, and 

 the sides of the hole are now parallel and considerably worn. In the 

 other, which is If by 2| inches, the hole is slightly bell-mouthed at each 

 end, though its sides are nearly straight. 



There is also in the Peabody Museum (13761) a beautiful example of 

 these perforated stones from the island of Santa Cruz, found by Mr. S. Bow- 

 ers. It is more flattened than the others, and differs from those heretofore 

 described in being polished on both ends, and even a portion of the inter- 

 vening surface shows polishing in places. The hole is slightly bell-mouthed, 

 with straight sides, and is highly polished throughout. A deep notch on 

 one side near the hole, caused by a flaw in the stone, is as much polished 

 as the surface adjoining, which, as mentioned in other instances, seems 

 favorable to the theory that these stones were sometimes fastened to shafts 

 by hide or leather thongs. Certainly the polished surface on this stone 

 could not have been brought about simply by handling, for the natural 

 cavity on its side and the edges of the hole through its centre could 

 not have been reached, much less rubbed smooth, by the skin of the hand 

 during any ordinary use of the implement as a weight to a digging-stick. 

 This specimen is 2 inches thick by 3£ in diameter, and the hole is 1\ 

 inches wide. 



From the island of San Nicholas numerous examples of these de- 

 pressed globular stones have been obtained by Mr. Schumacher ; two of 

 them are in the Peabody Museum, and others are in the Smithsonian Insti- 

 tution. On Plate X, Figs. 33, 34, 35, 36, and 38 are taken from San 

 Nicholas specimens. 



Fig. 34 represents one now in the Smithsonian Institution (18420). 

 It is of a soft stone, probably a clay slate, and is 2 inches thick by 2 J in 

 diameter. The hole tapers from both ends. 



Fig. 36 is taken from another Smithsonian specimen (18444). This 

 is symmetrical, and is well made from a hard stone, probably basalt. It is 

 about 24 inches thick and 3^ in diameter. The hole, as is well shown in 

 the figure, is deeply countersunk on both faces. 



Fig. 33 is from one in the Peabody Museum (9353), and is very much
