PLATE XXXVIII. MOUNT EREBUS. 



FIG. 1 (Map B). From a photograph taken by Mr FORD (Fo. 201, -plate) ; 

 looking N.-E. from the frozen surface of M'Murdo Sound, Dec. 1903. 



FIG. 2 (Map B). From a photograph by E. W. SKELTON (Sk. 212, ^-plate) ; taken 

 from the W. 



FIG. 3 (Map B). From a photograph by E. W. SKELTON (Sk. 63, ^-plate), 

 March 9, 1902; taken looking to the N.-N.-W. from the Barrier surface on 

 the S. side of Eoss Island. 



At a height of 12,922 feet the pennant of "smoke" from the crater of Mount 

 Erebus, which appears in Fig. 3, formed a valuable meteorological asset as a wind- 

 vane for the upper air-currents. 



Half-way down the right-hand slope, i.e. the eastern slope, also in Fig. 3, 

 may be seen part of an old crater lip, the same which is most clearly visible 

 in the photogravure Plate XXXVII., but appearing on the left side, since that 

 picture is taken from the N., and this one, Fig. 3, is from the S. 



Fig. 1 shows Mount Erebus from the S.-W., with some very typical storm 

 clouds.
