(probably the lower), the junction in one place being vertical. The 

 Drift apparently consists of the usual three members, but all are 

 much contorted, and in the upper clay are seen two large boulders 

 or prominences of Chalk. So the section appears from above ; it 

 is visible, though not so well, from below, but it could only be 

 examined by a bird, for the crest of the cliff must be fully 120 feet 

 above the beach. 



These two localities show the Drifts apparently lying at very 

 high angles, and they are not the only instances. 



(6) Between the Lenzerbach and Sassnitz, in the cliffs under the 

 Blockhouse at the corner of the forest, and some yards above the 

 shore, is found the usual grey lower Boulder Clay, with the line of 

 boulders at the bottom ; it rests upon Chalk, with bands of nodular

flint, which dip on the whole at a rather higher angle than the 

 section of the (slightly irregular) surface of junction. Over this clay 

 comes the usual stratified sand, capped by the upper (more sandy) 

 clay, which passes up into a rather confusedly mixed clay and sand, 

 containing one or two boulders and probably representing the Ober- 

 diluvium. The base of the Drift, as shown in the diagram 

 (fig. 8), first slopes downward at an angle of 25° to 30°, and then, 

 on coming within 3 or 4 yards of the beach, descends almost verti- 

 cally. In the lower part of the section the grey Boulder Clay is 

 seen to rest against an upright face of Chalk and to cut across the
