ioioI TABULAR BERGS 23 
more than two or three feet in thickness. 'I had hoped 
that we should not meet it till we reached latitude 66\ 
or at least 66.' We decided to work to the south and 
west as far as the open water would allow, and have 
met with some success. At 4 p.m., as I write, we are 
still in open water, having kept a fairly straight course 
and come through five or six light streams of ice, none 
more than 300 yards across. 
We have passed some very beautiful bergs, mostly 
tabular. The heights have varied from 60 to 80 feet, and 
I am getting to think that this part of the Antarctic 
yields few bergs of greater altitude. 
Two bergs deserve some description. One, passed very 
close on port hand in order that it might be cincmato- 
graphed, was about 80 feet in height, and tabular. It 
seemed to have been calved at a comparatively recent 
date. 
Straight strata of hard white nM with ' intrusions ' of blue Ice.

The above picture shows its peculiarities, and points 
to the desirability of close examination of other berg faces. 
There seemed to be a distinct difference of origin between 
the upper and lower portions of the berg, as though a land 
glacier had been covered by layer after layer of seasonal 
snow. Then again, what I have described as ' intrusive
