Hambledon Hills, and the leader was not only able to point 
out the solid geology very effectively, but also the locaHties 
at which the glacial overflows trench the lower parts of the 
ridge. 
Ascending Hood Hill an exposure of the Hydraulic Lime- 
stone (Lower Oolite) was examined, showing the decalcification 
of the limestone running across the bedding. Above this, on the 
725-foot contour, a moraine was found full of cherts, andesites, 
and other foreign rocks. On the summit of Hood's Hill is the 
Lower Calcareous Grit full of the ramifying concretions that 
characterise it at Filey Brigg. The summit is trenched with 
earthworks in a peculiar manner. 
Crossing the steep valley between Hoods Hill and Roulston 
Scar, which may have been a lake-channel, but the landsHps 
from both sides have considerably masked the original shape 
of the valley, the steep face of Lower Calcareous Grit was reached 
under which is the Kellaways Rock without any Oxford Clay. 
After a short rest on the top of the Scar to regain wind and 
enjoy the far view, a rapid descent was made to Gormire, a 
curious little lake in an overflow channel under Whitestone 
Cliff. The evidences of landsUps are so numerous all round 
Whitestone Cliff that it is fairly evident that the channel at 
both ends of Gormire has been blocked by slipped material, 
impounding the drainage, and terraced landslip ridges can be 
traced up the cliff face. Parallel to the Gormire westwards 
are two other overflow-channels exactly imitating the curve 
of the Gormire channel, which form a most interesting example 
of a series of glacier-lake channels, draining the water impounded 
by the ice at three stages of its advance or retreat. Finally 
a visit was paid to a fine section in the Dogger and Lower 
Estuarian series at Cleaves, whence the party returned by 
wagonette to Thirsk, after a most instructive and enjoyable 
excursion, in perfect weather. 
The fourth General Meeting and Field Excursion were 
held at Middle ton- in-Teesdale on July 21st and 22nd, under 
the presidency of Mr. WiUiam Gregson, F.G.S., and the leader- 
ship of Mr. Arthur R. Dwerryhouse, M.Sc, F.G.S.
