 or ten feet lona;, two broad, and one thick. 

 Sometimes they were ftill bigger, but fre- 

 quently much lei's. Hereabouts they lay in 

 ftrata one above another, the thicknefs of 

 each ftratum being about a foot. The 

 length and breadth were different, but 

 commonly luch as I have before mentioned. 

 Thev muff commonly dig three or four 

 feet before they reach the firil ftratum. 

 The looie ground above that ftratum, is 

 full of little pieces of this ftone. This 

 ground is the common brick coloured foil, 

 which is univerfal here, and coniifts of fand 

 and clay, though the former is more plen- 

 tiful. The looie pieces of glimmer which

 broken off from the great ftrata of ilone. 



It muft be obierved that when the 

 people build with this ftone, they take care 

 to turn the flat fide of it outwards. But as 

 that cannot always be done, the ftone be- 

 ing frequently rough on all fides, it is eafi- 

 ly cut fmooth with tools, iince it is foft, 

 and not very difficult to be broken. The 

 ftones however are unequal in thicknefs, 

 and therefore by putting them together 

 they cannot be kept in fuch ftraight lines as 

 bricks. It fometimes likewife happens that 

 pieces break cif when they are cut, and
