 Many deposits of gravel and sand near Newton Abbot, supposed to be 

 U. Greensand, are shown to be Drift. The only true patches of Green- 

 sand in the district are those on Melber Down and E. of Combe Farm.

 The " Head " at the bottom of the valley has been chiefly derived from 

 the older gravels, which it greatly resembles. Reference is made to
