Yol. 57.] DRIFTS OF THE BALTIC COAST OP GERMANY. 9 



a remnant of a much larger mass ; and this part of the coast rather 

 nearly corresponds with a pre-Glacial Chalk-cliff, against which 

 the Drift was deposited. The latter has gradually been washed 

 away, and this remnant, which, like one or two instances described 

 by us in Moen, was lodged in a hollow of the Chalk, has alone 

 escaped the waves. 



lY. The Jasmund District. 



Favoured by magnificent weather we again examined every 

 section near Crampas-Sassnitz, and on the coast between it and 

 Stubbenkammer, not only from above, but also from below ; for 

 this time we were able to walk, without any interruption, from one 

 place to the other along the beach. We also made the sea-passage 

 five times. As the steamer keeps near the coast, we found this 

 very helpful, the sections being exhibited in a much truer per- 

 spective.^ 



We must apologize for two or three slips in topography. The 

 most serious has been already corrected. It arose from suppressing 

 the wrong pair of sketches in order to reduce tbe number of illustra- 

 tions : those left represent a section near the Kollicker Bach instead 

 of near the Waldhalle ; and the error, in the revision of the proofs 

 at a busy time, unfortunately passed undetected, for the two 

 sections are much alike. The difference is that in the Kollicker-Ufer 

 section, Drift appears on both sides of a rib of Chalk, but in the 

 Waldhalle section only on one side, and the whitish boulder-clay is 

 more strongly developed in the latter. The description holds 

 equally good, if we strike out the references to the three aiguilles ^ 

 and the words ' east of the Kestaurant.' The second slip, as well as 

 a little vagueness regarding one or two other localities, is due to 

 most of our work having been done before we obtained a map on a 

 convenient scale. A section figured on p. 320 (in our previous paper) 

 is described as ' under the Blockhouse at the corner of the forest.' 

 It is about I mile north of this position, which is more nearly that 

 of the ' pocket ' of Drift mentioned on the preceding page. 



Apart from these we have nothing to withdraw, aud are able to 

 make some additions which we think important. We desire at the 

 outset to repeat, if possible in more emphatic terms, that between 

 Biigen and Cromer there is no analogy: the Drift^ is 

 a local incident in the Chalk, not the Chalk in the 

 Drift. The total outcrops of the Glacial deposits measured near 

 sea-level can not be more than a tenth, perhaps even less than a 

 twelfth (allowing for slips) of the Cretaceous. The Chalk in these 

 cliffs is as obviously in situ as it is in the precipices of Speeton, or 

 in those between Freshwater Gate and the Needles. 



The three members of this Drift, as a rule, are only well seen 



^ Beyond Stubbenkammer there seems to be little of interest, but at Lohme 

 Chalk apparently is exposed underneath Drift. 



^ We .find that these are called Wissower Klinken. 



^ We refer, of course, to the Tripartite Drift (Unter Diluvium).
