The speed increased as the wind freshened, but the ice was melting everywhere; it trembled beneath the feet of the anxious watchers, and might open at any moment. But they would not think of that; they were buoyed up with hope; safety was at hand, on the land they were rapidly nearing. They shouted—they made signals—they were in a delirium of excitement.
At half-past seven the ice was much nearer the land, but it was visibly melting, and sinking rapidly; water was gushing from it, and the waves were washing over it, sweeping off the terrified quadrupeds before the eyes of the colonists. Every instant they expected the whole mass to be engulfed, and it was necessary to lighten it like a sinking vessel. Every means was tried to check the dissolution; the earth and sand were carefully spread about, especially at the edges of the ice, to protect it from the direct influence of the sunbeams; and furs were laid here and there, as being bad conductors of heat. But it was all of no avail; the lower portion of the ice began to crack, and several fissures opened in the surface. It was now but a question of moments!
Night set in, and there was nothing left for the poor colonists to do to quicken the speed of the islet. Some of them tried to paddle about on planks. The coast was still four miles to windward.
It was a dark gloomy night, without any moon, and Hobson, whose heroic courage did not even now fail him, shouted—
“A signal, my friends! a signal!” A pile was made of all the remaining combustibles—two or three planks and a beam. It was set fire to, and bright flames soon shot up, but the strip of ice continued to melt and sink. Presently the little hill alone remained above water, and on it the despairing wretches, with the few animals left alive, huddled together, the bear growling fiercely.
The water was still rising, and there was no sign that anyone on land had seen the signal. In less than a quarter of an hour they must all be swallowed up.
Could nothing be done to make the ice last longer? In three hours, three short hours, they might reach the land, which was now but three miles to windward.
“Oh!” cried Hobson, “if only I could stop the ice from melting! I would give my life to know how! Yes, I would give my life!”
“There is one way,” suddenly replied a voice.
It was Thomas Black who spoke, the astronomer, who had not opened his lips for so long, and who had long since appeared dead to all that was going on.
“Yes,” he continued, “there is one way of checking the dissolution of the ice—there is one way of saving us all.”
All gathered eagerly round the speaker, and looked at him inquiringly. They thought they must have misheard what he said.
“Well!” asked Hobson, “what way do you mean?”
“To the pumps!” replied Black simply.
Was he mad? Did he take the ice for a sinking vessel, with ten feet of water in the hold?
The air pumps were at hand, together with the air vessel, which Hobson had been using as a reservoir for drinking water, but of what use could they be? Could they harden the ice, which was melting all over?
“He is mad!” exclaimed Long.
“To the pumps!” repeated the astronomer; “fill the reservoir with air!”
“Do as he tells you!” cried Mrs. Barnett.
The pumps were attached to the reservoir, the cover of which was closed and bolted. The pumps were then at once set to work, and the air was condensed under the pressure of several atmospheres. Then Black, taking one of the leather pipes connected with the reservoir, and opening the cock, let the condensed air escape, walking round the ice wherever it was melting.
Everyone was astonished at the effect produced. Wherever the air was projected by the astronomer, the fissures filled up, and the surface re-froze.
“Hurrah! hurrah!” shouted all with one voice.
It was tiring enough to work the pumps, but there were plenty of volunteers. The edges of the ice were again solidified, as if under the influence of intense cold.
“You have saved us, Mr. Black,” said Lieutenant Hobson.
“Nothing could be more natural,” replied the astronomer quietly.
Nothing, in fact, could have been more natural; and the physical effect produced may be described as follows:—
There were two reasons for the relegation:—First, under the pressure of the air, the water vaporised on the surface of the ice produced intense cold, and the compressed air in expanding abstracted the heat from the thawed surface, which immediately re-froze. Wherever the ice was opening the cold cemented the edges, so that it gradually regained its original solidity.
This went on for several hours, and the colonists, buoyed up by hope, toiled on with unwearying zeal.
They were nearing the coast, and when they were about a quarter of a mile from it, the bear plunged into the sea, and swimming to the shore, soon disappeared.
A few minutes afterwards the ice ran aground upon a beach, and the few animals still upon it hurried away in the darkness. The colonists “disembarked,” and falling on their knees, returned thanks to God for their miraculous deliverance.

Conclusion
It was on the island of Blejinie, the last of the Aleutian group, at the extreme south of Bering Sea, that all the colonists of Fort Hope at last landed, after having traversed eighteen hundred miles since the breaking-up of the ice. They were hospitably received by some Aleutian fishermen who had hurried to their assistance, and were soon able to communicate with some English agents of the Hudson’s Bay Company.
After all the details we have given, it is needless to dwell on the courage and energy of the brave little band, which had proved itself worthy of its noble leader. We know how all struggled with their misfortunes, and
