shows a similar admixture, and contains a few boulders of Triassic 

 sandstone. 



There is an interesting section near a quarry in a dyke on the 

 hillside above Wood House. The Boulder Clay, which rests upon 

 a smoothed and striated surface of Skiddaw Slate, is a composite 

 mixture of variegated drift, as shown in the appended section 

 (fig. 4). Boulders of slate are beautifully striated.

[1= Roughly-stratified slaty drift, with boulders: matrix brown and gritty, 

 sometimes approximating to a gravel; 2= Yellowish loam, with fewer 

 stones, but more of large size and distant origin than in 1 ; 3 = Strip of 

 brick-red sand with stones; 4=Tavvny-eoloured sand with stones resting 

 upon 1 & 2 in a ' pocketiy manner.' At the bottom (left) of the section, 

 the clay (1) rests upon a glaciated surface of Skiddaw Slate.] 



Near Sledbank there is an admixture of slaty and red-clay drift, 

 with sandy and gravelly layers streaked out in a south-easterly 

 direction. It is overlain by 2 feet of tawny-yellow sand, and 

 underlain by a similar thickness of warm red sand, both containing 

 stones. The boulders are chiefly slates, lavas, tuffs, ashes, and 

 Eskdale Granite, some of the latter being very rotten. Boulders 

 of Ennerdale Granophyre and St. Bees Sandstone were also noted.
