Thus the proximity of this ice was not so decidedly indicated by the decrease of the temperature of either the air or water as I have before witnessed, which was probably owing to the recent arrival of the stream at this point and its passing at too quick a rate for the effectual diffusion of its chilling influence beyond a short distance.

Still the decrease in both cases was sufficient to have given timely warning for a ship's performing any evolution that would have prevented the coming in contact with it had the thickness of the weather precluded a distant view of the danger.
The approach to ice would be more evidently pointed out in the Atlantic, or wherever the surface is not so continually chilled by the passing and the melting of ice as in this sea; and I should strongly recommend a strict hourly attention to the thermometrical state of the water at the surface in all parts where ships are exposed to the dangerous concussion of sailing icebergs, as a principal means of security.
The following day our ship came near another stream of ice and the approach to it was indicated by a decrease of the temperature of the water at the surface from 44 to 42 degrees.

A small pine-tree was picked up much shattered by the ice.

In the afternoon of the 30th a very dense fog came on; and about six P.M.when sailing before a fresh breeze we were suddenly involved in a heavy stream of ice.

Considerable difficulty was experienced in steering through the narrow channels between the different masses in this foggy weather, and the ship received several severe blows.
The water, as usual in the centre of the stream, was quite smooth, but we heard the waves beating violently against the outer edge of the ice.
There was some earthy matter on several of the pieces, and the whole body bore the appearance of recent separation from the land.
