These bergs are still a puzzle.

I rather cling to my original idea that they become domed when stranded and isolated.
These two bergs had left long tracks of open water in the pack.

We came through these making nearly 3 knots, but, alas! only in a direction which carried us a little east of south.

It was difficult to get from one tract to another, but the tracts themselves were quite clear of ice.

I noticed with rather a sinking that the floes on either side of us were assuming gigantic areas; one or two could not have been less than 2 or 3 miles across.
