A very apparent lowering of the level had taken place all along that part of the coast near Cape Bathurst, it was evidently gradually sinking down, and the sea had already encroached nearly as far as the lagoon.

The situation of the colonists was truly terrible, unable as they were to attempt to save their companions, and driven from the enceinte by the crashing avalanches, over which they had no power whatever. They could only wait, a prey to the most awful forebodings.

Day dawned at last, and how fearful a scene was presented by the districts around Cape Bathurst! The horizon was shut in on every side by ice-masses, but their advance appeared to be checked for the moment at least. The ruins of the ice-wall were at rest, and it was only now and then that a few blocks rolled down from the still tottering crests of the remaining icebergs. But the whole mass-a great part of its volume being sunk beneath the surface of the sea-was in the grasp of a powerful current, and was driving the island along with it to the south, that is to say, to the ocean, in the depths of which they would alike be engulfed.

Those who were thus borne along upon the island were not fully conscious of the peril in which they stood. They had their comrades to save, and amongst them the brave woman who had so won all their hearts, and for whom they would gladly have laid down their lives. The time for action had come, they could again approach the palisades, and there was not a moment to lose, as the poor creatures had already been buried beneath the avalanche for six hours.

We have already said that Cape Bathurst no longer existed. Struck by a huge iceberg it had fallen bodily upon the factory, breaking the boat and crushing the dog-house and stable with the poor creatures in them. The principal house next disappeared beneath the masses of earth and sand, upon which rolled blocks of ice to a height of fifty or sixty feet. The court of the fort was filled up, of the palisade not a post was to be seen, and it was from beneath this accumulation of earth, sand, and ice, that the victims were to be dug out.

Before beginning to work Hobson called the head carpenter to him, and asked if he thought the house could bear the weight of the avalanche.

"I think so, sir," replied Mac-Nab; "in fact, I may almost say I am sure of it. You remember how we strengthened it, it has been 'casemated,' and the vertical beams between the ceilings and floors must have offered great resistance; moreover, the layer of earth and sand with which the roof was first covered must have broken the shock of the fall of the blocks of ice from the icebergs." "God grant you may be right, Mac-Nab," replied Hobson, "and that we may be spared the great grief of losing our friends!"

The Lieutenant then sent for Mrs Joliffe, and asked her if plenty of provisions had been left in the house.

"Oh, yes," replied Mrs Joliffe, "there was plenty to eat in the pantry and kitchen."

"And any water?"

"Yes, water and rum too."

"All right, then," said Hobson, "they will not be starved-but how about air?"

To this question Mac-Nab could make no reply, and if, as he hoped, the house had not given way, the want of air would be the chief danger of the four victims. By prompt measures, however, they might yet be saved, and the first thing to be done was to open a communication with the outer air.

All set to work zealously, men and women alike seizing shovels and pickaxes. The masses of ice, sand, and earth, were vigorously attacked at the risk of provoking fresh downfalls; but the proceedings were ably directed by Mac-Nab.

It appeared to him best to begin at the top of the accumulated masses, so as to roll down loose blocks on the side of the lagoon. The smaller pieces were easily dealt with, with pick and crowbar, but the large blocks had to be broken up. Some of great size were melted with the aid of a large fire of resinous wood, and every means was tried to destroy or get rid of the ice in the shortest possible time.

But so great was the accumulation, that although all worked without pause, except when they snatched a little food, there was no sensible diminution in its amount when the sun disappeared below the horizon.
