erratic blocks ; the whole mass varying from forty to a hun 

 dred feet in thickness, but this only in a few spots. 



The angularity of many of the blocks in Nos. 3 and 4, and 

 the glaciated surfaces of others, and the transportation from 

 a distance attested by their crystalline nature, proves them to 

 belong to the northern drift or glacial period. 



It will be seen that the four subdivisions 2, 3, 4, and 5, begin 

 to rise at B, fig. 47, and that at c, where the cliff is 180 feet 

 high, there is a sharp flexure shared equally by the chalk and 

 the incumbent drift. Between D and G, fig. 48, we observe a 

 great fracture in the rocks with synclinal and anticlinal folds, 

 exhibited in cliffs nearly 300 feet high, the drift beds partici 

 pating in all the bendings of the chalk ; that is to say, the 

 three lower members of the drift, including No. 2, which, at 

 the point s in this diagram, contains the shells of recent 

 species before alluded to. 



Near the northern end of the Moens Klint, at a place 

 called 'Taler,' more than 300 feet high, are seen similar 

 folds, so sharp that there is an appearance of four distinct 

 alternations of the glacial and cretaceous formations in vertical 

 or highly inclined beds ; the chalk at one point bending over, 

 so that the position of all the beds is reversed. 



But the most wonderful shiftings and faultings of the beds 

 are observable in the Dronningestol, part of the same cliff, 400 

 feet in perpendicular height, where, as shown in fig. 49 (p. 346), 

 the drift is thoroughly entangled and mixed up with the 

 dislocated chalk. 



If we follow the lines of fault, we may see, says M. Puggaard, 

 along the planes of contact of the shifted beds, the marks of 

 polishing and rubbing, which the chalk flints have undergone, 

 as have many stones in the gravel of the drift, and some of 

 these have also been forced into the soft chalk. The manner 

 in which the top of some of the arches of bent chalk have 

 been cut off in this and several adjoining sections, attests the
