The three friends remained silent, and looked fixedly at the chart of the fearful Polar regions, towards which they were being irresistibly drawn, and which have hitherto successfully resisted all attempts to explore them.

"There is, then, nothing to be done? Nothing to try?" said Mrs Barnett after a pause.

"Nothing, madam," replied Hobson; "nothing whatever. We must wait; we must all pray for the speedy arrival of the Arctic winter generally so much dreaded by sailors, but which alone can save us now. The winter will bring ice, our only anchor of salvation, the only power which can arrest the course of this wandering island."

CHAPTER III.

A TOUR OF THE ISLAND.

From that day, July 18th, it was decided that the bearings should be taken as on board a vessel whenever the state of the atmosphere rendered the operation possible. Was not the island, in fact, a disabled ship, tossed about without sails or helm.

The next day after taking the bearings, Hobson announced that without change of latitude the island had advanced several miles farther west. Mac-Nab was ordered to commence the construction of a huge boat, Hobson telling him, in explanation, that he proposed making a reconnaissance of the coast as far as Russian America next summer. The carpenter asked no further questions, but proceeded to choose his wood, and fixed upon the beach at the foot of Cape Bathurst as his dockyard, so that he might easily be able to launch his vessel.

Hobson intended to set out the same day on his excursion round the island in which he and his comrades were imprisoned. Many changes might take place in the configuration of this sheet of ice, subject as it was to the influence of the variable temperature of the waves, and it was important to determine its actual form at the present time, its area, and its thickness in different parts. The point of rupture, which was most likely at the isthmus itself, ought to be examined with special care; the fracture being still fresh, it might be possible to ascertain the exact arrangement of the stratified layers of ice and earth of which the soil of the island was composed.

But in the afternoon the sky clouded over suddenly, and a violent squall, accompanied with thick mists, swept down upon the fort. Presently torrents of rain fell, and large hailstones rattled on the roof, whilst a few distant claps of thunder were heard, a phenomenon of exceedingly rare occurrence in such elevated latitudes.
