 quartz* The black and red fand is not

 about a quarter of an inch deep; when it 

 was carefully taken off, the fand under it be- 

 came of a deeper red the deeper it lay, and 

 its depth was commonly greater than that of 

 the former* When this was carefully taken 

 away, the white fand of quartz appeared 

 mixed very much at top with the red fand, 

 but growing purer the deeper it lay. This 

 white fand was above four inches deep, 

 had round grains, which made it entirely 

 like a pearl fand. Below this was a pale 

 grey angulated quartz fand. In fome places 

 the garnet coloured fand lay uppermoft, 

 and this grey 'angulated one immediately 

 under it, without a grain of either the black 

 or the white fand. 



I CANNOT determine the origin of the 

 black or fteel-coloured fand, for it was not
