MOETAES MADE OP STONE. 75 



The dimensions of this mortar are: Greatest diameter, 14.4 inches; 

 height, exteriorly, 9 inches ; depth of vessel inside, 6.9 inches ; breadth of 

 rim, 1.2 inches. 



An example of these large mortars, of nearly the same dimensions, 

 is made from, hard granitic or basaltic rock. It is very regular in its 

 shape, and evenly pecked over its exterior surface. The bottom is flat- 

 tened and quite smooth, evidently from long use. The rim is quite even, 

 with a slight outward slope. An interesting feature is the careful mend- 

 ing of the vessel by securely replacing a portion of one side by means of 

 asphaltum. 



The measurements of this -specimen are as follows : Greatest diameter, 

 14.2 inches; height, exteriorly, 9.5 inches; depth of vessel inside, 7.7 

 inches ; breadth of rim, 1.2 inches. 



Allied to the above is a broken specimen of dense granitic rock, quite 

 regular in form and with the usual pecked surfaces. The bottom is flattened. 

 The rim projects outwardly slightly, and its inner edge is worn by the 

 movement of the pestle. 



This mortar measures in greatest diameter 14 inches; height, exteriorly, 

 8.8 inches; depth of vessel inside, 7.6 inches; breadth of rim, varying from 

 1 to 2 inches. 



A mortar of less diameter, but somewhat larger capacity, of compara- 

 tively regular shape, well finished and smooth, with the rim slightly sloping 

 outwards, and worn on both the outer and inner edges, is of hard, fine- 

 grained sandstone. 



Its measurements are: Greatest, diameter, 13.5 inches; height, ex- 

 teriorly, 10.5 inches; depth of vessel inside, 8.3 inches; breadth of rim, 

 1 inch. 



Another example, made of soft sandstone, and smooth upon the surface, 

 is moderately regular in outline. The rim is much worn, slightly sloping 

 outwardly, and undulating. The bottom is worn from long use. 



This mortar measures in greatest diameter 13.5 inches ; height, ex- 

 teriorly, 7.1 inches; depth of vessel inside, 5.1 inches; breadth of rim, 1 

 inch. 



Another, of nearly the same dimensions, is made of medium hard,
