A STUDY OF CHIRIQUIAN ANTIQUITIES. 



There is a small group of chipped and polished implements including alike the 

 largest and smallest celts in the collection. The former are made of andesitic 

 lava and all come from Gualaca. One of the handsomest is reproduced in figure 7.

Its length is 23.2 centimeters and greatest breadth 11.5 centimeters. The broad edge 

 forms a sweeping curve, the ends of which are carried along the lateral margins more 

 than half the length of the implement. The pointed pole is not 

 polished. This type is not constant ; for as the lateral margins become 

 straighter, the curve of the edge flattens somewhat, tending to 

 produce more or less triangular outlines. The diminutive celts of 

 which figure 8 is an example take the latter form. They are 

 chipped from a dark compact material, probably silicified ash or 

 tuff. 



Chisels, which are relatively rare, are characterized by being 

 broadest at the base and tapering gradually to the edge. The 

 materials used are porphyritic andesite, tuff, and a black volcanic

 polished and faceted so as to produce an octagonal section. The 

 faceting of the lateral margins is of rare occurrence among Chiriquian stone imple- 

 ments. Of similar workmanship is the chisel shown in figure 10, except that the
