SCIENTIFIC RESULTS 



inches high, and formed by the gas from the organic mud 

 underneath collecting as large bubbles under the imper- 

 vious skin of fungus. 



We saw altogether three whole specimens of Crabeater 

 seals and a hke number of Weddells dead on the hills 

 hereabouts, and the moraines are covered with scattered 

 remains. One of the Crabeater carcases was lying at a 

 steep angle on one of the banks bordering the northern 

 stream I have mentioned earher in my notes, and at a 

 height above sea-level of considerably over two hundred 

 feet, but this does not compare with the heights at which 

 we found similar skeletons in the Ferrar Glacier Valley, 

 no less than three being found there between the two 

 thousand- and three thousand-foot levels. 



Moraines in the East Fork of the Ferrar Glacier 



The last ten miles of the east valley of the Ferrar 

 Glacier below the first ice-falls is occupied by a peculiar 

 variety of ice which, at its highest point, is not forty feet 

 above sea-level, and is apparently composed largely of 

 frozen slush formed by the inundation of the winter snow- 

 drifts by the summer thaw- water. With this are inter- 

 mingled patches of macrocrystalline ice exactly compar- 

 able with the ice so common on the lakes at Cape Royds, 

 especially Blue Lake, and evidently caused by the freez- 

 ing of pure thaw-water. I propose to give the detailed 

 evidence regarding the nature of this stretch of ice when 

 the scientific results of the expedition are published in 

 full. At present I will only mention certain deposits, a 

 portion of which is visible as a series of small hills pro- 

 truding above the ice-surface, which hills, from their occur- 

 rence in a fairly straight line, appear to be the more 

 prominent peaks of a partially submerged ridge. These 

 deposits I examined carefully on December 31, 1908, on
