 In such cases, where a vertical section was exposed which really 

 showed the structure of the ice, contortion was the almost uni- 

 versal rule. 



In a few places the contortion of laminae was seen to be

striking where debris was absent, or where but little was present. 

 This, however, is the exception rather than the rule (Figs. 17 and 

 18). Such a case is indicated in Fig. 6, which represents a sort 

 of fcetal glacier — a tiny lobe projecting out from the edge of 

 the ice-cap in the vicinity of Meteor Bay, some twenty-five or 

 thirty miles northeast of Cape York. Attention is especially 

 called to the position of the contortions, a position which is well- 

 nigh universal. The bends are such as to suggest that the upper 

 layers are crowding on faster than the lower. In a single case, 

 only, were the contortions seen to lie in the opposite position, 

 and this was on the opposite side of the same lobe.
