THE GEOLOGY OF FRANZ JOSEF LAND.

to a height of about 200 feet. At the top of the cliffs is a 

 plateau which slopes northward and finally ends in a low shore. 

 It was visited by U8 in May 1897, when the surface was covered 

 with snow, so that very little could be seen. * 



Hooker Island. 



To this I refer here merely in order to draw attention to the 

 remarkably perfect, curved, basin-like structure of the columnar 

 basalt, of which I have endeavoured to convey some idea in the 

 appended sketch (fig. 5).

Eaton Island 



is a small low islet, apparently composed of rounded basaltic 

 stones and shingle, being little more than a shoal protruding above 

 the level of the sea. 



Bruce Island 



lies about 8 miles north-west of Northbrook Island. It is irre- 

 gularly oval in shape, measuring about 12 miles from north to 

 south and 10 from east to west. It is remarkable as being entirely 

 surrounded by an ice-face, from 10 to 60 or 70 feet in height, and 

 as having only small portions of its surface exposed. The slopes 

 asceud from the ice-cliff until at about the elevation of 1000 feet 

 the snow-surface forms a more or less level, slightly undulating 

 plateau. Depressions in the general surface give some indications 

 of the configuration of the land. At a short distance from the ice- 

 face (100 to 300 yards) the actual surface is occasionally exposed, 

 and smaller points of rock protrude at different levels on the
