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.

Every one 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.

CHAPTER XXIV

CONCLUSION.

It was on the island of Blejinie, the last of the Aleutian group, at the extreme south of Behring 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 how patiently they had submitted to the will of God. We have seen Mrs Barnett cheering every one by her example and sympathy; and we know that neither she nor those with her yielded to despair when the peninsula on which Fort Hope had been built was converted into a wandering island, when that island became an islet, and the islet a strip of ice, nor even when that strip of ice was melting beneath the combined influence of sun and waves. If the scheme of the Company was a failure, if the new fort had perished, no one could possibly blame Hobson or his companions, who had gone through such extraordinary and unexpected trials.
