CORRYS WITH OR WITHOUT LAKE-BASINS. 127 



floors. Corrys liave no perceptible preference for 

 places which were most exposed to the action of the 

 sea. 



b. These hollows are of a different order from the 

 other shapes of the mountains on which they occur, 

 which argues a special mode of formation. 



c. The rock-basin, when there is one, is an integral 

 part of the corry, formed along with it, and not sub- 

 sequently by a different operation. 



d. The cauldron-like shape of the corry is just what 

 we should expect would be superinduced by an agent 

 formed, moving, and working as a small glacier. 



e. These hollows have a decided preference for the 

 higher mountains. 



/. They affect the highest parts of mountains. 



g. The majority of them face northerly or easterly. 



h. According to Professor Ramsay, the corry is 

 eminently characteristic of all glacier countries, past 

 and present. 



Notwithstanding this observer's conclusions, an 

 examination for ourselves has led us to believe that 

 ice is only a minor agent in the formation of corrys, 

 they being mainly due to the faulting, jointing, and 

 dislocation of rock masses, combined with marine 

 and glacial action, and probably also with meteoric 

 abrasion. In some corrys the mass of the drift will 

 be glacial, in others marine, and in a few meteoric ; 

 and these different drifts could not have accumulated
