PLATE XLIX. WHERE LAND AND BARRIER MEET AT 



CAPE CROZIER. 



FIG. 1 (Map B). From a photograph taken by R. W. SKELTON (Sk. 192, ^-plate), 

 Oct. 18, 1902 ; looking N.-W. from the pressure ridges at Cape Crozier ; 

 Ross Sea is just visible in the distance. 



FIG. 2 (Map B). From a photograph taken by R. W. SKELTON (Sk. 79, ^-plate), 

 Jan. 23, 1902 ; looking S. from the open sea, to the point of impact between 

 land and Barrier. 



We have here the same spot viewed from N. and S., and in each may be seen 

 the mass of Barrier ice crumbling to pieces as it forces a way by the Crozier cliffs 

 and floats to sea. Were it but possible to have a series of such photographs as 

 these, taken by successive expeditions, and taken at the same spot with intervals of 

 years, surely facts of great interest would be brought to view. 



Compare, for example, the photographs which are accidentally comparable, 

 Fig. 2 on this page and a similar photograph in Mr Bernacchi's book, To the South 

 Polar Regions, p. 257, taken in 1899. The field of ice which appears then to have 

 swept down from the slopes of Mount Terror to form an unbroken ice-slope to the 

 sea, is now cut short to expose new rock-cliffs capped by cliifs of freshly fractured 

 ice ; the promontory is gone, leaving open what is possibly a new bay, for the one 

 and only Emperor Penguin rookery yet known. 



Ross's Barrier is advancing northward at the rate of nearly a third of a mile a 

 year, but the sea-face is more rapidly receding, as we know by comparing observed 

 positions of our own with those taken in 1840 by Sir James Ross. Instead of 

 being now some 18 miles or more farther N. than it was in Ross's time, the sea-face 

 of the Barrier is actually some 10 to 15 miles farther to the S.
