590 MR, A. R, DWERRYHOUSE ON THE GLACIATION oF {| Aug. 1902, 
(1800 feet) there is a deposit of peat, resting upon gravel formed 
of local material and for the most part angular. This gravelly 
deposit is continuous with true Glacial material on both sides of 
the col. 
Ireshope Burn is formed by the union of two principal tributaries. 
The eastern stream cuts through thin Drift, containing angular and 
Subangular stones; but in the western tributary, which is the 
larger, occur esker-like mounds of gravel of a more rounded type. 
Below the junction of the two streams the stones become striated, 
and the amount of striation increases at still lower levels. 
There is a railway-cutting 30 feet deep, three quarters of a mile 
west of Westgate Station (60). This is in stiff Boulder-Clay con- 
taining many striated stones. A thickness of 10 feet of the same 
material is to be seen close to Westgate Station. About a quarter 
of a mile below Westgate, the river cuts through similar material 
resting upon limestone, the surface of which is planed. 
Similar deposits are exposed in the cutting 1 mile above 
Eastgate Station (61), the boulders being very large and well- 
striated. In a quarry on the north side of the railway, half a mile 
above Stanhope, there is an exposure of 20 feet of blue Boulder-Clay 
resting on the ‘ solid rock.’ 
In the large quarry at Jack’s Crag (62), about 1 mile south-east 
of Stanhope, is a very fine striated surface. The surface originally 
exposed measured 100 yards by 50, and was moutonnée and 
striated throughout. There is still a large portion exposed, and 
the striz pass under the Boulder-Clay, the surface being therefore 
of unknown extent. ‘This is the finest example of a striated surface 
that I have seen in the North of England. The direction of the 
striz is south 50° east, or approximately that of the main valley. 
The Boulder-Clay in this section varies from 15 to 20 feet in 
thickness, and contains boulders of Carboniferous Limestone, sand- 
stone, Millstone Grit, and less commonly basalt. Many of the 
boulders, especially those consisting of Carboniferous Limestone, 
are striated. 
The ‘ Great Limestone’ is quarried at Ashes Quarry, Stanhope 
(63), and is covered by stiff bluish Boulder-Clay containing lime- 
stone- and sandstone-boulders, to a depth varying between 20 and 
40 feet. When exposed to the air this clay weathers to a reddish- - 
brown. <A year or two ago there were fine examples of striz to be 
seen in this quarry; but the portion of the quarry where they 
occur is not now being worked. Mr. W. M. Egglestone, of Stanhope, 
Secretary of the Weardale Naturalists’ Field-Club, informed me that 
the direction of the striz was north-north-west to south-south-east. 
That is the direction of the valley of Stanhope Burn, at the mouth 
of which the quarry is situated. 
In the portion of Weardale that extends between Stanhope and 
Frosterley there are patches of Drift on both sides of the river; but 
at many places the limestone-series appears at the surface. Thus, 
in the long quarry on the side of the main road between Stanhope 
and Frosterley, there is very little if any Drift, and the uppermost
