Fig. 4, when viewed in the direction of the arrow, appears 
to have a pedestal much narrower than itself; but, when seen

would appear to have been left by the splashing down of rain- 
water from the boulders, may average about six inches in 
height, or nearly the same as the pedestals on the Eelwyseg
