The boat which had been built at the foot of the cape was completely destroyed. The last hope of the unfortunate colonists was gone!
As they stood watching the awful scene, the buildings, formerly occupied by the soldiers and women, and from which they had escaped in time, gave way beneath an immense block of ice which fell upon them. A cry of despair burst from the lips of the houseless outcasts.
"And the others, where are they?" cried the Lieutenant in heart-rending tones.
"There!" replied Mac-Nab, pointing to the heap of sand, earth, and ice, beneath which the principal house had entirely disappeared.
Yes, the illustrious lady traveller, Madge, Kalumah, and Thomas Black, were buried beneath the avalanche which had surprised them in their sleep!
CHAPTER XVIII.
ALL AT WORK.
Fearful catastrophe had occurred. The ice-wall had been flung upon the wandering island, the volume below the water being five times that of the projecting part, it had come under the influence of the submarine currents, and, opening a way for itself between the broken ice-masses, it had fallen bodily upon Victoria Island, which, driven along by this mighty propelling force, was drifting rapidly to the south.
Mac-Nab and his companions, aroused by the noise of the avalanche dashing down upon the dog-house, stable, and principal house, had been able to escape in time, but now the work of destruction was complete. Not a trace remained of the buildings in which they had slept, and the island was bearing all its inhabitants with it to the unfathomable depths of the ocean! Perhaps, however, Mrs Barnett, Madge, Kalumah, and the astronomer, were still living! Dead or alive they must be dug out.
