592 MR. A. R. DWERRYHOUSE ON THE GLACIATION or [ Aug. 1902, 
and contains material derived from the Teesdale area. Thus, by 
the footbridge below Mayland Cottage (67) there is a boulder of 
andesite-breccia (Borrowdale Series) ; and close to Mayland Cottage, 
one consisting of pink rhyolite, which is striated. 
On the road between ‘ Robins Castle’ and Mayland Cottage are 
many boulders of basalt, which are also plentiful in the village of 
Woodlands (68). 
In the village of Lynsack (950 feet) is a boulder of andesite; 
while on the main road 300 yards south-east of that village, and 
at a height of 900: feet, is a boulder of Shap Granite measuring 
2x2x 12 feet. 
The country between Bishop Auckland and West Auckland (69) is 
covered with Drift; but there are few sections to show its nature. 
There is a large boulder of basalt in the village of West Auck- 
land, at the corner of the road leading to Etherley. Near the 
bridge carrying the Etherley road over the River Gaunless is a 
section 30 feet deep through a mound of gravelly clay, which 
contains boulders of basalt, Coal-Measure sandstone, and Carboni- 
ferous Limestone. Above Spring-Bank railway-crossing the Gaunless 
cuts through similar Drift to a depth of 40 fect, and is still running 
in Drift: but nearer Etherley (70) the Drift ceases at a height of 
550 feet, although there are still a few scattered boulders. 
In the village of Etherley, Drift is absent, as is also the case 
at the cross-roads north of the village. A quarry in Coal-Measure 
sandstone north of the crest of the hill, and on the road between 
Ktherley and Witton-le-Wear, shows the rock passing up into a 
normal subsoil, there being no Glacial Drift. Descending towards. 
Witton-le-Wear, the Drift again appears at a height of about 
400 feet above the sea. 
The country to the north of Wear-Valley Junction (71) is 
covered by a reddish sandy Boulder-Clay, of a character quite 
different from that of Weardale. In a quarry near High-Nook 
Station (72), lying between the road and the railway, 6 feet of red 
Boulder-Clay rests upon Coal-Measure sandstone. The clay contains 
Eskdale Granite (Cumberland), Silurian grit (South of Scotland), 
and yarious Carboniferous sandstones, including Gannister and 
Millstone Grit. Near this quarry are several heaps of small boulders 
lying at the roadside, which I was informed had been picked off the 
neighbouring fields. They consist for the most part of Millstone 
Grit and Coal-Measure sandstone, but also include Silurian grit 
and an andesitic ash similar to those of the Borrowdale Series. 
At the bridge over Abbey Burn, north of ‘ The Hermitage’ (73), 
there is a section 30 feet deep, in yellowish-brown Boulder- 
Clay, containing the granites of Eskdale (Cumberland) and Criffel, 
together with a large quantity of local material. The Drift in 
Wascrow Beck is principally of a brown colour, and contains local 
material only.
