Passed some distance away a warship convoying another vessel. The infantry now have to wear boots to get their feet used to them again. A few sea-birds are re-turning, but not regular followers like those we had in the South. The warm regions of the earth seem to have no attraction for the sea-birds. The whistle blew like thunder 3 times one morning, but none of us know why. We get war news by wireless daily. Have seen in the distance a school of whales spouting and splashing. It is quite evident that they do not spout water but that the plume is simply their hot breath condensing in the cooler air. Bullen points out that in the Cachalot. (I am trying to rewrite this page as the original has just been blown overboard). At about 3.30 p.m. the long expected destroyers swooped down upon us like a flight of birds. They whizzed up alongside and after some signalling our ships took up a new alignment and proceeded under their escort. Even in a calm sea they roll about in a surprising manner and one realises what they must be during the long winters in the cruel North Sea.
