C^v^r of th^ face of the Earth is, from the great hardnefs, 
^L]i3:4coiifequefitJy tbedai'ableners^aad unalterable qua- 
lity of thii Mmeralj above any other in Nature, For 
though many things are called S^nd, from the linallnefs 
and little Cphaefion, or drynefs oi the grains, yet this 
kind of M^^^^/^^^/z^ iS''^;?^ above all others keeps its natural

although this is not England, yet the Sea hath but acci-

that of the Northerne Mountains will beft appear in the 
Table. Now the nakednefs of the Woolds, is from tKe 
fmaUnefs of its land, which readily yielded not only to
