Describes three platforms; first, marine, of Pliocene age, at 450 feet above sea, 

 second at 750 feet seen about Camelford, and at foot of Delabole Hill, third at a 

 little less than lOOO feet, first recognized on Davidstow Moor. Superficial deposits 

 which bear tin above 750 feet platform differ very much in phiccs from those 

 below. Here ancient wash is preserved, perhaps protected, from denudation which 

 has destroyed them below this level. The deposits are not so concentrated as the 

 stream-sorted material below. Deposits have been worked in the past, but on 

 account of difficulty of separating' wolframite, were abandoned. Since that difficulty 

 has been removed, the industry is reviving, and the wolframite is more valuable 

 than the tin ore.
