MISCELLANEOUS OBJECTS MADE OF STONE.

Eastern States; but it is very doubtful, considering the very friable charac- 

 ter of the mineral, if this specimen was ever used in any way connected 



with the sharpening- or pol- 

 ishing- of other stone imple- 

 ments, although it might 

 have been employed in 

 polishing articles of bone, 

 shell, or wood. 



In the collection made 



by Dr. Yarrow's party are 



two sandstone celts, one of 



Polish ing-stoiio, ? i. which, from La Patera, is 



of peculiar interest, as it still has adhering to its base a quantity of asphal- 



tum, showing that by the use of this material a handle had been attached. 



The edge of this speci- 

 men is still well de- 

 fined, and shows a 

 considerable degree of 

 Poiisiiing-stouc,? side view, i. polish. The material 



is a moderately dense sandstone, but, as exemplified by the celt itself, not 

 capable of sustaining much hard usage. Although quite symmetrical in 

 shape the specimen can in no wise compare with similar celts of porphyry 

 and other minerals found in the Central and Eastern States. 



The accompanying specimen from Dos Pueblos, being devoid of any- 

 thing like a cutting edge, and smoothed but little, if any, upon its sides, 

 might readil}- be considered a chance-shaped water-worn pebble were it not 

 that its sloping edge gives some indication of having been once a polished 

 cutting edge now crumbled away. The mineral is now so light, porous, 

 and friable, that a cutting implement could not be made of it ; but as these 

 conditions are probably the result of long exposure to intense heat, this 

 stone implement may originally have been as well formed as the other. 



[Among the man)' interesting articles obtained by Mr. Schumacher in 

 Pots Valley (the place where the extensive manufacture of the soapstone 

 pots was carried on) on the island of Santa Catalina, there is a large
