To manage this they cleared out the movable things in the boat, arranging all the cargo (except the mess chest), as fast as it was removed, in the shape of a wall extending across from the stern of the boat to the hummock. In this way, with the help of thwarts, two oars, and some blocks of ice, a rough wall was raised, about four feet high, enclosing a three-cornered space eight feet in width, having the hummock and starboard side of the boat for its sides, and the cargo wall (through which a hole had been left as a doorway) for its end or "base."
Next, a roof must be contrived. The mast and two oars were set in a leaning position from the outer gunwale of the boat, where they rested firmly upon the thwart-cleats, up against the hummock, to which they were securely wedged.
It had now become dark, and Katy lighted the lantern. Tug and Jim, covered with snow, brought their last sled-load and added it to the wall, throwing all their little stock of firewood, which amounted to about three bushels, into the hut. Then all hands set to work in the wind, which blew in sharp gusts now and then over the crest of the hummock, to stretch the sails upon the rafters formed by the mast and oars and thus form an awning-roof.
The handling of the heavy mainsail proved an extremely difficult matter. Once it blew quite away from their grasp, and went off in the darkness, but Jim and the dog gave chase, and soon caught it, Rex grabbing it with his teeth, and so holding on to it till the others came to the rescue. At the next attempt they succeeded in fastening one end, after which the task grew easier.
The mainsail fairly in place, the jib was next hoisted across the end, and here its leg-of-mutton shape was a great advantage, for when the broad lower part was hung against the hummock wall the narrowing peak just fitted between the sloping roof and the top of the wall.
When the two sails had been fastened, the party found themselves covered rudely but pretty tightly, and the spare canvas remained to serve as a carpet, which was greatly needed. Plenty of snow and cold were "lying round loose" yet, but to be inside was far better than to be out of doors. That this safety and warmth were possible to their frail structure was owing, of course, to the fact that it stood under the lee of the tall ice wall, which acted as a shield against the force of the gale.
