Very cold day. Red leaded waterways on fore mess deck in forenoon. Part of ship in afternoon. Told off with 2 hands from each part, about 3.15 pm, to make net for picket boat to drag for floating mine which had broken loose from Harbour defence and was drifting down with the tide towards the ships. It was however picked up outside the bridge by the “Ostrich” before we had got the net down to the boat. Duty part.
