Fr of varying size. The stone itself, assumes every

known to put on; it varies also much by a change 
in the component parts ; again, it differs much in 
density, some spots being considerably softened,

some sites where the decomposition has proceeded 
to its greatest limit. The granite of the two south- 
west counties however is far famed for durability, 
and supports a part of our commerce. A certain 
proportion of the white Cornish stone also, is 
shipped for the porcelain manufactories, it being 
convertible into a fine enamel. 
The climate of the moor is proverbially bleak 
and chilly, and highly conducive to health and
