PEBFOEATED STOKES.

tion of one face, of natural size, is of steatite, and has four of the lozenge- 

 figure bands extending from the hole to the sides of the stone. 



The method of 

 making these perfo- 

 rated stones is well 

 illustrated by three 

 specimens obtained 

 by Mr. Schumacher 

 in Pots Valley, isl- 

 and of Santa Gata- 

 lina. One of these 

 (P. M. 13425) is a 

 pebble of indurated 

 mica schist. The 

 natural surface of 

 about half of the 



Perforated stone, with incised lines, from island of Santa Catalina. pebble has not been 



disturbed, but the remaining portion has been hammered into the shape de- 

 sired, leaving the stone about 2 inches thick by from 3 to 3J in diameter. 



Taken by itself this stone would probably be con- 

 sidered as simply a rude hammer, but studied in 

 connection with the. two other specimens, show- 

 ing further stages in the process of manufacture, 

 and compared with perfectly made examples of 

 / the same material, I have not the slightest hesi- 

 tation in considering it as showing the first stage 

 in the manufacture of a perforated stone of ordi- 

 naiy size. The second stage of manufacture is 



Perforated stone, Tvith incised lines, . 



from Santa Barbara. shown by a mass ot serpentine ot the same di- 



mensions as that of mica schist just mentioned. This mass still has its 

 original surface on one face. All the rest of the stone has been pecked 

 by a pointed implement, after having been first brought nearty to its 

 present form by blows which detached larger masses than the secondary 

 pecking. The stone is now in the stage immediately preceding its perfo-
