The Quarterly journal of the Geological Society of London . beyond the village of Stoke Gabriel. Here 120 MR. A. J. JTJKES-BROWXE ON THE AGE AND [May 1907, the pJateau still has a width of at least a mile and a half, beingbounded on the north by ground which rises rapidly to 500 feet,on the west and south-west across the Dart by hills of 400 feet,and on the north-west by a hill of 300 feet. It would seem,therefore, that the western termination of the Brixham plateauis still distinguishable near Stoke Gabriel, in spite of the greatmodification Avhich the surface of the country has undergone, owingchiefly to the passage of the River Dart through the district. As regards evidence of age, it is clear that the plateau is of somegeological antiquity, and that its surface has not influenced thedrainage of the area; for, near Stoke Gabriel, the plateau does notdrain eastward, as might have been expected, but is traversed by Pig. 6.—Map showing the plateau-areas and their probable former connexion across Torbay. 1 \ V ^\ it - \. [The inner area marked out near Torquay represents the Warberry-Lincoinberidge or butte.] a valley which has its origin in the northern watershed and openssouthward into the Dart. The drainage-system of the area, likethat near Torquay, has evidently been established upon a vanishedsurface which passed high above the existing plateau. Again, the plateau-surface is newer than Permian time, since asmall strip of Permian is faulted down below its level south ofSaltern Cove. To what period can we then attribute a plateauof such antiquity and of such a height above the sea, unless to anearly Tertiary period ? Finally, since the level of this plain closelyapproximates to that of the plateau-remnants west and south ofTorquay, it is only reasonable to suppose that the two plains are Vol. 6$.] ORIGIN OF THE PLATEAUS AROUND TORQUAY. 121 of the same date and that they were in some way connected withone another.
