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.

"Really, the wind does us more good than harm now," Aleck remarked, "for it drifts the snow under the boatsledge and against the wall, and, if it keeps on, will soon stop up all the holes, and leave us boxed into a tighter house than our old snow-chinked cabin back at the river."

"Mebbe it'll bury us," said Jim, in an awful whisper.

"Guess not. Anyhow, we can have a fire first—there are holes enough left yet to let the smoke out. Tug, just shovel the drifted snow out of the house, or pack it between the bobs under the boat, while I whittle some kindling. There won't any more blow in—the drift's too high now."

CAMPING AGAINST AN ICE WALL.

"Shall I boil tea or coffee?" asked Katy.
