he first saw it. Since then it has deteriorated still more. On the 

 other handj the cleavage was better developed than I had ever 

 seen it. 



The deposits are banked up against an old Pleistocene cliff of the 

 Caninia oolite (here exceedingly veined with calcite), which is part 

 of the long valley-side feature. Here and there it is vertical, or even 

 slightly undercut. The main floor of the quarry is at about 

 60 feet O.D., the top of the whole suite of drifts at about 

 120 feet O.D., so that the depth seen is 60 feet. But in the outer 

 parts of the quarry, 54 yards away from the cliff, where the floor is 

 cut down to about 50 feet, the sand appears again, and above it the

Fig. 3. — The Holly Lane Section. Scale : 1 inch = 27 feet. The base-line 

 is at 60 feet above sea-level. The highest point of the Pleistocene deposit 

 is at 120 feet above sea-level. The deposits shown are in ascending 

 order : Lower breccia, coarse breccia, sandy loam, loamy sand, upper 

 breccia. The cave is shown as when filled with the lower breccia. 



upper breccia, which has come down on the dip. The deposits have 

 also been cut back eastwards about 51 yards from \k^ cave, and 

 there we fuid another good section, but the cliff-brow, and with it 

 the summit of the drifts, has declined, so that the depth seen 

 is only about 20 feet. AH is sandy breccia with blocks about 

 3-4inches in diameter, save for four Icn'^icular, 1ft. bands, dipping at 

 about 30 degrees, of loamy sand with cleavage. So far as can now 

 be made out, the fine deposits have here almost wedged out, allowing 

 the upper and lower breccias to coalesce. The crag here overhangs 

 40 degrees, with sand adhering to the undercut face. The whole 

 mass of drifts dies out rapidly westwards, and has disappeared at
