end. The hole in the centre, as will be seen in the figure, is very small, 

 and was made by boring from both faces. The mineral is probably ser- 

 pentine. As the specimen belongs to the Smithsonian 

 Institution, and is not before me as I write, I cannot 

 give a more detailed description. 



Among the perforated stones found by Mr. Bowers 

 on the island of San Miguel are three (P. M. 13691) 

 oval pebbles, which have not only been perforated, 

 but their sides have been more or less flattened. One 

 of, these, a worked pebble of basalt, is shown of actual 

 size in Fig. 57. This has been worked smooth and flat on both faces, as 

 well as on the sides, and its perforation is large, regular, and smooth, 

 though slightly tapering to 

 the centre. This stone is 1 

 inch thick by about 2J 

 inches wide and 34 in length. 



The second specimen is 

 a granite pebble, about ^ of 

 an inch thicker, J inch wider, 

 and 1 inch longer than the 

 last. The sides are not so 

 even and the hole is not so 

 large nor so well made. Mr. 

 Evans, in his exhaustive

ments of Great Britain, has figured* a very similar perforated pebble, 

 which was found in Cambridgeshire, and mentions several other English 

 specimens of this character. 



The third example is also a granite pebble, with a perforation § of an 

 inch in diameter at its contracted part. It is thicker than either of the 

 others, and the ends of the stone have not been flattened.! 



The last of the perforated granite pebbles which I have to mention

t Since this page was put in type, Mr. Evans has kindly given to the Peabody Museum a perforated 

 pebble from the north of Ireland which closely resembles this California stone.
