“We brought certain stores aboard and provided space on deck for the dogs in case they had to be removed from the floe at short notice. We had run a 500-fathom steel wire round the ship, snow-huts, and kennels, with a loop out to the lead ahead, where the dredge was used. This wire was supported on ice-pillars and it served as a guide in bad weather when the view was obscured by driving snow and a man might have lost himself altogether. I had this wire cut in five places, since otherwise it might have been dragged across our section of the floe with damaging effect in the event of the ice splitting suddenly.”
