174 GLACIOLOGY 



level was formed of well-stratified layers of old snow. The bergs were from 78 

 to 80 feet in height. The interesting observation was made by Captain F. P. 

 Evans, when sounding around these bergs towards the end of 1908, that they were 

 aground in water 14 fathoms in depth. Thus in this case only little more than 

 half of the berg was submerged. This particular berg was of the typical tabular 

 variety, bounded by almost vertical sides, and was about a quarter of a mile in 

 length. 



Another and similar berg, evidently broken off from the same mass, is shown on 

 Fig. 2 of Plate XLVI. 



It wiU be noticed that this berg, wliich has somewhat the shape of a massive 

 castle wall, stands on a wide shelving platform formed by this marine erosion. The 

 wall itself has been somewhat undermined, giving its summit a turreted outline. 

 Icicles can be seen dependent from its overhanging portions. It will be noticed 

 that in the photograph the part of the berg which has been most undercut is 

 naturally that which faces the blizzard wind, that is, the right-hand side of the 

 berg, as shown in the photograph.
