North Sea, which has left large morainic mounds, and numbers 
of beautiful dry valleys at considerable elevations, which were 
cut by the water flowing from the ice-front when the usual 
lines of drainage were choked with ice. The lie of these 
moraines and glacial valleys showed that the Cheviots formed 
the dividing line in local glacial movements, the local glaciers to 
the north being deflected northwards, and beaten back on to the 
coast, whilst those to the south were deflected southwards along 
the coast, as Yorkshire evidence conclusive^ proved. 
The examination of the Cheviot granite showed it to be 
very fine-grained at the margin on the hillside above Langleeford 
and at the faulted junction in Harthope. The fine-grained 
character of the highest beds on Cheviot and the patch of 
porphyrite on one of the northern spurs showed that the central 
mass of granite had not been much denuded, and explained the 
paucity of granite boulders in the local drift. Strings of grano- 
phyre (i.e., very fine-grained material of the same composition as 
the granite) passed through the porphyrites and the granite. 
One specimen was obtained below Long Crag which showed 
a small vein of granophyre passing across the junction of the 
granite with the porphyrite. Veins of tourmaline were found 
along the edges of the granite, and fragments of granite traversed 
by tourmaline veins were found in the "cone of dejection" of 
each of the three small streams descending on the north side 
of the Harthope valley. ^ 
A discussion followed in which several of the members took 
part, and the meeting concluded with unanimous votes of thanks 
to the Chairman and the readers of papers. 
On Sunday afternoon many of the members accepted the kind 
invitation of Mr. and Mrs. G. G. Butler to visit Ewart Park, 
and have tea. The interesting collection of curios in the gallery 
was shown, and an hour was spent in the spacious gardens. 
On Monday, July 16th, the party drove to Roddam to 
complete the examination of the Dene, and see the fine sections 
of the basement Carboniferous conglomerates exposed therein. 
A heavy thunderstorm coming on, the investigation was anything
