diameter, which imply that they were carried by ice in a sea 

 of sufficient depth to float large ice-bergs. 



4th. After this subsidence, the re-elevation and partial 

 denudation of the cretaceous and glacial beds took place 

 during a general upward movement, like that now ex 

 perienced in parts of Sweden and Norway. 



In regard to the lines of movement in Moen, M. Puggaard 

 believes, after an elaborate comparison of the cliffs with the 

 interior of the island, that they took at least three distinct 

 directions at as many successive eras, all of post-glacial date ; 

 the first line running from ESE. to WNW., with lines 

 of fracture at right angles to them ; the second running from 

 SSE. to NNW., also with fractures in a transverse direc 

 tion ; and lastly, a sinking in a N. and S. direction, with other 

 subsidences of contemporaneous date running at right angles, 

 or E. and W. 



When we approach the north-west end of Moens Klint, or 

 the range of coast above described, the strata begin to be 

 less bent and broken, and, after travelling for a short distance 

 beyond, we find the chalk and overlying drift in the same 

 horizontal position as at the southern end of the Moens Klint. 

 What makes these convulsions the more striking is the fact 

 that in the other adjoining Danish islands, as well as in a 

 large part of Moen itself, both the secondary and tertiary 

 formations are quite undisturbed. 



It is impossible to behold such effects of reiterated local 

 movements, all of post-tertiary date, without reflecting that, 

 but for the accidental presence of the stratified drift, all of 

 which might easily, where there has been so much denudation, 

 have been missing, even if it had once existed, we might 

 have referred the vertically and flexures and faults of the 

 rocks to an ancient period, such as the era between the chalk 

 with flints and the Maestricht chalk, or to the time of the 

 latter formation, or to the eocene, or miocene, or older
