It was on the night of the 7th April that the actual breaking up of the ice commenced. In the morning the Lieutenant, Mrs Barnett, Kalumah, and Sergeant Long, had climbed to the summit of Cape Bathurst, and saw that a great change had taken place in the chain of icebergs. The huge barrier had parted nearly in the middle, and now formed two separate masses, the larger of which seemed to be moving northwards.
Was it the Kamtchatka Current which produced this motion? Would the floating island take the same direction? The intense anxiety of the Lieutenant and his companions can easily be imagined. Their fate might now be decided in a few hours, and if they should be drifted some hundred miles to the north, it would be very difficult to reach the continent in a vessel so small as theirs.
Unfortunately it was impossible to ascertain the nature or extent of the displacement which was going on. One thing was, however, evident, the island was not yet moving, at least not in the same direction as the ice-wall. It therefore seemed probable that whilst part of the ice field was floating to the north, that portion immediately surrounding the island still remained stationary.
This displacement of the icebergs did not in the least alter the opinion of the young Esquimaux. Kalumah still maintained that the thaw would proceed from north to south, and that the ice wall would shortly feel the influence of the Behring Current. To make herself more easily understood, she traced the direction of the current on the sand with a little piece of wood, and made signs that in following it the island must approach the American continent. No argument could shake her conviction on this point, and it was almost impossible not to feel reassured when listening to the confident expressions of the intelligent native girl.
The events of the 8th, 9th, and 10th April, seemed, however, to prove Kalumah to be in the wrong. The northern portion of the chain of icebergs drifted farther and farther north. The breaking up of the ice proceeded rapidly and with a great noise, and the ice field opened all round the island with a deafening crash. Out of doors it was impossible to hear one's self speak, a ceaseless roar like that of artillery drowned every other sound.
About half a mile from the coast on that part of the island overlooked by Cape Bathurst, the blocks of ice were already beginning to crowd together, and to pile themselves upon each other. The ice-wall had broken up into numerous separate icebergs, which were drifting towards the north. At least it seemed as if they were moving in that direction. Hobson became more and more uneasy, and nothing that Kalumah could say reassured him. He replied by counter-arguments, which could not shake her faith in her own belief.
At last, on the morning of the 11th April, Hobson showed Kalumah the last icebergs disappearing in the north, and again endeavoured to prove to her that facts were against her.
"No, no!" replied Kalumah, with an air of greater conviction than ever, "no, the icebergs are not going to the north, but our island is going to the south!"
She might perhaps be right after all, and Hobson was much struck by this last reply. It was really possible that the motion of the icebergs towards the north was only apparent, and that Victoria Island, dragged along with the ice-field, was drifting towards the strait. But it was impossible to ascertain whether this were really the case, as neither the latitude nor longitude could be taken.
The situation was aggravated by a phenomenon peculiar to the Polar regions, which rendered it still darker and more impossible to take observations of any kind.
