CHAPTER III. A TOUR OF THE ISLAND. rROM 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 pro- ceeded 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.
