816 GEOLOGICAL OBSERVATIONS IN SOUTH GEORGIA. 



fig. l), in the instructive view of the coast from Cape George to Royal Bay (PL LXXXIX, 

 fig. l), and in greater detail in the view of Adventure Harbour (PI. XCI, fig. 2). 

 Marine abrasion during one of the stages between the uplifts no doubt excavated the 

 caves at Tonsberg Point (PI. LXXXIV, fig. l). That the country has been stationary 

 for some time past is indicated by the widespread alluvial plains near sea-level 

 (PI. LXXXVI, fig. 2). 



Mr Ferguson's photographs, therefore, represent South Georgia as a glaciated 

 mountain land composed of ancient folded rocks, in which the folds have no direct 

 relation to the existing topography, as the country had been planed down to a 

 pene-plane. It is obviously part of a much larger land. In modern times subsidence 

 has drowned the northern coast, and the effects of recent uplifts show that the area 

 is probably still in a state of oscillation, in which the vertical movements are 

 separated by intervals of comparative rest. 



Further reference may also be made to the plates accompanying Mr Theodore 

 E. Salvesen's paper " The Whale Fisheries of the Falkland Islands and Dependencies," 

 appearing in The Scientific Results of the Voyage of the " Scotia" vol. iv, part 

 xix, in which several features of South Georgian landscape appear.
