No incident occurred between the 10th and 21st March, but there were indications of the approaching change of season. The temperature varied from 43? to 50? Fahrenheit, and it appeared likely that the breaking up of the ice would commence suddenly. Fresh crevasses opened, and the unfrozen water flooded the surface of the ice. As the whalers poetically express it, the "wounds of the ice-field bled copiously," and the opening of these "wounds" was accompanied by a sound like the roar of artillery. A warm rain fell for several hours, and accelerated the dissolution of the solid coating of the ocean.
The birds, ptarmigans, puffins, ducks, &c., which had deserted the island in the beginning of the winter, now returned in large numbers. Marbre and Sabine killed a few of them, and on some were found the tickets tied round their necks by the Lieutenant several months before. Flocks of white trumpeter swans also reappeared, and filled the air with their loud clarion tones; whilst the quadrupeds, rodents, and carnivora alike continued to frequent the vicinity of the fort like tame domestic animals.
Whenever the state of the sky permitted, which was almost every day, Hobson took the altitude of the sun. Sometimes Mrs Barnett, who had become quite expert in handling the sextant, assisted him, or took the observation in his stead. It was now most important to note the very slightest changes in the latitude and longitude of the island. It was still doubtful to which current it would be subject after the thaw, and the question whether it would be drifted north or south was the chief subject of the discussions between the Lieutenant and Mrs Barnett.
The brave lady had always given proof of an energy superior to that of most of her sex, and now she was to be seen every day braving fatigue, and venturing on to the half decomposed, or "pancake" ice, in all weathers, through snow or rain, and on her return to the factory ready to cheer and help everybody, and to superintend all that was going on. We must add that her efforts were ably seconded by the faithful Madge.
Mrs Barnett had compelled herself to look the future firmly in the face, and although she could not fail to fear for the safety of all, and sad presentiments haunted her, she never allowed herself to betray any uneasiness. Her courage and confidence never seemed to waver, she was as ever the kind encouraging friend of each and all, and none could have dreamt of the conflict of spirit going on beneath her quiet exterior demeanour. Lieutenant Hobson's admiration of her character was unbounded, and he had also entire confidence in Kalumah, often trusting to her natural instinct as implicitly as a hunter to that of his dog.
The young Esquimaux was, in fact, very intelligent, and familiar from babyhood with the phenomena of the Polar regions. On board a whaler she might have advantageously replaced many an ice-master or pilot whose business it is to guide a boat amongst the ice.
Every day Kalumah went to examine the state of the ice-field.
The nature of the noise produced by the breaking of the icebergs in the distance was enough to tell her how far the decomposition had advanced. No foot was surer than hers upon the ice, no one could spring more lightly forwards than she when her instinct told her that the smooth surface was rotten underneath, and she would scud across an ice-field riddled with fissures without a moment's hesitation.
From the 20th to the 30th March, the thaw made rapid progress. Rain fell abundantly and accelerated the dissolution of the ice. It was to be hoped that the ice-field would soon open right across, and that in about fifteen days Hobson would be able to steer his boat into the open sea. He was determined to lose no time, as he did not know but that the Kamtchatka Current might sweep the island to the north before it could come under the influence of the Behring Current.
"But," Kalumah repeated again and again, "there is no fear of that, the breaking up of the ice does not proceed upwards but downwards. The danger is there!" she added, pointing to the south in the direction of the vast Pacific Ocean.
