Nevertheless, the man who had mined at Caribou seemed to feel that some contribution from him was necessary to offset the huge success of that window.  He did not feel called upon to help to split logs for the roof of the Big Cabin, but he sat cutting and whittling away at a little shelf which he said was to be nailed up at the right of the Big Cabin door.  Its use was not apparent, but no one dared call it a “fancy touch,” for Mac was a miner, and had been to Caribou.

When the shelf was nailed up, its maker brought forth out of his medicine-chest a bottle of Perry Davis’s Pain-killer.

“Now at Caribou,” says he, “they haven’t got any more thermometers kicking round than we have here, but they discovered that when Perry Davis congeals you must keep a sharp look-out for frost-bite, and when Perry Davis freezes solid, you’d better mind your eye and stay in your cabin, if you don’t want to die on the trail.”  With which he tied a string round Perry Davis’s neck, set the bottle up on the shelf, and secured it firmly in place.  They all agreed it was a grand advantage to have been to Caribou!

But Mac knew things that he had probably not learned there, about trees, and rocks, and beasts, and their manners and customs and family names.  If there were more than a half-truth in the significant lament of a very different man, “I should be a poet if only I knew the names of things,” then, indeed, Samuel MacCann was equipped to make a mark in literature.

From the time he set foot on the volcanic shore of St Michael’s Island, Mac had begun his “collection.”

Nowadays, when he would spend over “that truck of his” hours that might profitably (considering his talents) be employed in helping to fortify the camp against the Arctic winter, his companions felt it little use to remonstrate.

By themselves they got on rapidly with work on the roof, very much helped by three days’ unexpectedly mild weather.  When the split logs had been marshalled together on each side of the comb, they covered them with dried moss and spruce boughs.

Over all they laid a thick blanket of the earth which had been dug out to make a level foundation.  The cracks in the walls were chinked with moss and mud-mortar.  The floor was the naked ground, “to be carpeted with skins by-and-by,” so Mac said; but nobody believed Mac would put a skin to any such sensible use.

The unreasonable mildness of three or four days and the little surface thaw, came to an abrupt end in a cold rain that turned to sleet as it fell.  Nobody felt like going far afield just then, even after game, but they had set the snare that Nicholas told the Boy about on that first encounter in the wood.  Nicholas, it seemed, had given him a noose made of twisted sinew, and showed how it worked in a running loop.  He had illustrated the virtue of this noose when attached to a pole balanced in the crotch of a tree, caught over a horizontal stick by means of a small wooden pin tied to the snare.  A touch at the light end of the suspended pole (where the baited loop dangles) loosens the pin, and the heavy end of the pole falls, hanging ptarmigan or partridge in the air.
