a further unpleasantness occurred in the arrival of a host of the terrible 'killer' whales. These were reaping a harvest of seal in the broken-up ice, and cruised among the floes with their immense black fins sticking up, and blowing with a terrific roar. The Killer is scientifically known as the Orca, and, though far smaller than the sperm and other large whales, is a much more dangerous animal. He is armed with a huge iron jaw and great blunt socket teeth. Killers act in concert, too, and, as you may remember, nearly got Ponting when we were unloading the ship, by pressing up the thin ice from beneath and splitting it in all directions.
"It took us over six hours to get close to the fast ice, which proved to be the Barrier, some immense chunks of which we actually saw break off and join the pack. Close in, the motion was less owing to the jambing up of the ice somewhere farther west. We had only just cleared the Strait in time though, as all the ice in the centre, released beyond Cape Armitage, headed off into the middle of the Strait, and thence to the Ross Sea. Our spirits rose as we neared the Barrier edge, and I made for a big sloping floe which I expected would be touching; at any rate I anticipated no difficulty. We rushed up the slope towards safety, and were little prepared for the scene that met our eyes at the top. All along the Barrier face a broad lane of water from thirty to forty feet wide extended. This was filled with smashed-up brash ice, which was heaving up and down to the swell like the contents of a cauldron. Killers were cruising there with fiendish activity, and the Barrier edge was a sheer cliff of ice on the other side fifteen to twenty feet high. It was a case of so near and yet so far. Suddenly our great sloping floe calved in two, so we beat a hasty retreat. I selected a sound-looking floe just clear of this turmoil, that was at least ten feet thick, and fairly rounded, with a flat surface. Here we collected everything and having done all that man could do, we fed the beasts and took counsel.
"Cherry and Crean both volunteered to do anything, in the spirit they had shown right through. It appeared
