PLATE III. PACK-ICE. 



FIG. 1. From a photograph by L. C. BERNACCHI (Be. 16, j-plate), Jan. 17, 1902; 

 taken in the pack-ice of Wood Bay. 



FIG. 2. From a photograph by R. W. SKELTON (Sk. 15, i-plate), Nov. 16, 1901, 

 at 9 A.M., S. lat. 62, E. long. 1391. 



In the upper figure, which represents a fair example of ice-blink in the 

 sky, the pack-ice consists of floes of moderate size and thickness becoming 

 closely packed. The undisturbed edges of these floes show that there has 

 been but little movement amongst them, and they contrast markedly with the 

 broken and jostled edges of loose and water- washed pieces on the outskirts of 

 the ice-belt, such as are shown in Fig. 2, from a photograph which was taken 

 in November at the edge of the open ocean. The sky in the lower picture is 

 a typical water-sky with but little reflected light, and dark when compared 

 with that of Fig. 1. 



Compare Figures 1 and 2 of Plate II.
