PLATE CXXVL FINGER MOUNTAIN AND DEPOT NUNATAK. 



FIG. 1 (Map B). From a photograph by R. W. SKELTON (Sk. 82, -plate), Jan. 

 1903 ; looking westward up Ferrar Glacier; shows Finger Mountain on the 

 left, Finger Mountain Falls in the centre, and the left bank of the glacier on 

 the right. 



FIG. 2 (Map B). From a photograph by R. W. SKELTON (Sk. 98, ^-plate), Jan. 

 1903 ; showing the cliffs of Finger Mountain, with a dolerite-sill in the 

 Beacon Sandstone of Royal Society Range. It was near this point that Mr 

 Ferrar discovered unmistakeable fossil plant remains as "thin, black, 

 irregular bands in a pure white sandstone," but owing to decay of the plants 

 and to changes produced by a neighbouring sheet of dolerite, their character- 

 istics are indeterminate. See Ferrar, Nat. Hist. Rep., vol. i., pp. 44, 48, 

 50; Scott, Voyage of the 'Discovery,' vol. ii., pp. 240, 242, 287. 



FIG. 3 (Map B). From a photograph by R. W. SKELTON (Sk. 94, ^-plate), Jan. 

 1903 ; showing Depot Nunatak, a mass of columnar dolerite at the edge of 

 the inland-ice which begins its descent eastward here as Ferrar Glacier, 

 passing by the northern end of Royal Society Range to reach sea-level in 

 M'Murdo Sound. 



FIG. 4 (Map B). From a photograph by R. W. SKELTON (Sk. 95, |-plate), Jan. 

 1903 ; shows the dolerite cliff of Depot Nunatak, which rises to a height 

 of nearly 500 feet from the glacier surface, itself at this point 6000 feet 

 above the sea. Ferrar, Nat. Hist. Rep., vol. i., p. 49 ; Scott, Voyage of 

 the 'Discovery,' vol. ii., pp. 140, 288.
