agglomerate with included fragments 6 inches in length. There 

 are a few boulders of soft red sandstone, and many well-striated 

 Skiddaw Slates from the neighbourhood of Cleator and Ennerdale. 



(ii) AYestern slope of Black Combe. — The Lower drift 

 rises from a level of about 250 feet near Pellside (half a mile east 

 of Bootle) to a height of over 400 feet near Whitbeck, falls ta 

 200 feet near Sledbank, but rises again to 300 feet at the mouth 

 of the AYhicham Valley. Skiddaw Slate debris becomes an in- 

 creasingly important constituent in a southerly direction, but there 

 is a great amount of Triassic debris throughout, as well as granitic 

 and andesitic material of all sizes. 



Between JP'ellside and Hall Foss (a mile south-east of Bootle) 

 the Boulder Clay is very sandy, and the hillside above its level has- 

 been scraped and polished by southward-moving ice which left 

 erratics and perched boulders upon the slopes above (p. 422).. 

 Between Hall Foss and Hole Gill the lower slopes are also scraped 

 and steepened, and boulders occur in the lower part of Hall Foss 

 above the level of the clay. A section near the footpath on the 

 northern side of Hole Gill Beck shows the interweaving of drifts — 

 chiefly brown and sandy at the western end, with slate-grey 

 material in the middle, and clayey drift with very little slate at 

 the eastern end. A pit on the south side shows variegated drift 

 with much slate-debris. 



A platform, the scarped face of which (pp. 434-35) is situated 

 from 50 to 100 yards west of the footpath, consists of unstratified 

 drift of a sandy texture, containing a considerable amount of slate. 

 Boulders of slate also lie on its surface. Xear Moukfoss Farm, 

 300 yards from the bare hillside, the drift is brown and sandy, 

 but unstratified. 



The lower of two pits by the road south of Whitbeck Mill 

 showed 12 feet of brown gritty boulder-clay, with much slate- 

 debris, resting on a foot or more of red sandy drift containing 

 lumps of red sticky loam and fragments of red sandstone and 

 shale. The bottom of the further pit was almost on a level with 

 the top of the last. It exposed 12 feet of more homogeneous 

 brown sandy drift full of stones, mostly of slate, but there were 

 also boulders of granite, etc. A tawny-yellow sand (probably 

 rainwash) following the slope of the hill crossed the edges of the 

 deposits, in both sections, obliquely. The slaty fragments in 

 the drift north of this point were mainly of the pale unhanded 

 felspathic type ; in these sections, however, the blue banded slates 

 begin to appear, and are quite common farther south. 



In Miller Gill, behind Whitbeck Mill, there is a beautifully 

 glaciated surface of slate, from which the boulder-clay has been 

 stripped away ; and 150 yards upstream is a second, the direction 

 of ice-movement in both cases having been to the south-east. 



A pit about 440 yards south-south-east of Whitbeck Church 

 shows 10 feet of slaty drift, with patches or streaks of loam and 

 red clay. Another section about a third of a mile to the south
