376 An JEolian Deposit at Clevedon. 



to the 50 ft. contour (Fig. 1), 370-500 yards south by west from the 

 Holly Laue quarry. It is about 170 yards long, and is the best section 

 in the drifts of the valley-floors. About 6 feet of ruddy loamy sand 

 are. seen, with a few stones, which are partly Coal Measure sand- 

 stone, partly Caninia oolite, the latter being more numerous on the 

 northern side. Not the faintest sign of stratification has been 

 detected even after frost, though the section is still vertical and clear. 

 Heavy minerals are more plentiful than on the hill-flanks, and more 

 facetted quartz was found here than anywhere else. 



Highdale. — Early in 1918 the roadwall at the 70 ft. level, between 

 the Fir Wood and the allotments, f mile north-east of the station 

 (Fig. 1), collapsed, and clearing for its rebuilding exposed for a while 

 a good section in more than 8 feet of loamy sand. There were some 

 angular blocks of the dolomitic Trias conglomerate which occurs 

 at that spot, and the sand was unstratified. It yielded Helix 

 aspersa Miill., the shells, though retaining traces of colour-banding, 

 being decayed and evidently old, and I think in situ. No base was 

 ■visible, and the drifts evidently form the gentle sandy slopes which 

 run down to the alluvium. About 200 yards to the W.S.W., 

 at 80-90 feet O.D., similar sand can be seen clinging to the 

 back of the steep little combe above Highdale Farm ; and a little of 

 it is also to be seen 180 yards further south-west, at the west end of 

 Highdale Avenue. 



Lower Clevedon. — Major A. B. Trestrail informs me that several 

 feet of loam were cut into when making the bowling-green in Princes 

 Eoad. Stony sand is visible above sandy slopes near St. John's 

 Church, and several feet of it are said to have been cut into when 

 building a vestry. It is also reported at the foundations of the houses 

 in St. John's Road, and as being banked up to several feet against 

 the east end of Hangstone crag (shown in Fig. 1 by the sharp south- 

 ward projection in the 50 ft. contour— though the crag just reaches 

 100 feet in height). That crag, and the quarry in Jesmond Road, 

 are bare ; but stony sand reappears between them and Clevedon 

 Hall, passing over the low part of the ridge to the " Green Beach ", 

 where, just to the west of the 50 ft. contour, a little sandy loam that 

 seems alien rests on limestone rubble at the cliff's brow. Sandy 

 breccias appear also at the roadside quarry on the southern side of 

 the Old Church Headland.
