The evidence under this head is necessarily a compilation; the very exceptional exposure of the old forest ground, and the nature of stream tin sections, leaving no room for personal investigation. The names of the observers are in most cases sufficient vouchers for the accuracy of their statements. The submerged forestare given first stream tin gravels to the general growth of the forests. The forest bed overlying the stream tin which Mr. Carne rightly synchronizes with the forest beds on the coast may represent a very brief portion of a long period of forestial growth.
