One, passed very close on port hand in order that it might be cinematographed, was about 80 feet in height, and tabular.

It seemed to have been calved at a comparatively recent date.
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 layers of blue ice' was a remarkable feature; one could imagine that these layers represent surfaces which have been transformed by regelation under hot sun and wind.
This point required investigation.
The second berg was distinguished by innumerable vertical cracks.

These seemed to run criss-cross and to weaken the structure, so that the various seracs formed by them had bent to different angles and shapes, giving a very irregular surface to the berg, and a face scarred with immense vertical fissures.
One imagines that such a berg has come from a region of ice disturbance such as King Edward's Land.
We have seen a good many whales to-day, rorquals with high black spouts--_Balaenoptera Sibbaldi_.
The birds with us: Antarctic and snow petrel--a fulmar--and this morning Cape pigeon.
We have pack ice farther north than expected, and it's impossible to interpret the fact.
