"No, I haven't. Matches were among the things you were to look after, and so I never gave them a thought."

The spirits of the lads, raised to a high pitch of expectation by the sight of Yim's lamp, suddenly sank to zero with the discovery that they had no means for lighting it. Yim, however, only smiled at their dismay. Of course he had long since learned the use of matches, and to appreciate them at their full value; but he also knew how to produce fire without their aid in the simplest manner ever devised by primitive man. It is the friction method of rubbing wood against wood, and, in one form or another, is used all over the world. It was known to the most ancient Egyptians, and is practised to-day by natives of the Amazon valley, dwellers on South Pacific islands, inhabitants of Polar regions, Indians of North America, and the negroes of Central Africa. These widely scattered peoples use various models of wooden drills, ploughs, or saws. But Yim's method is the simplest of all. When he saw that no matches were forthcoming, he said:

"A' yite. Me fix um." At the same time he produced two pieces of soft wood from some hiding place in his garments. One of these, known as the "spindle," was a stick about two feet long by three-quarters of an inch in diameter and having a rounded point. The other, called the "hearth," was flat, about eighteen inches in length, half an inch thick, and three inches wide. On its upper surface, close to one edge, were several slight cavities, each just large enough to hold the rounded end of the spindle, and from each was cut a narrow slot down the side of the hearth. This slot is an indispensable feature, and without it all efforts to produce fire by wood-friction must fail.

Laying the hearth on the flat side of a sledge runner and kneeling on it to hold it firmly in position, Yim set the rounded end of his spindle in one of its depressions, and holding the upper end between the palms of his hands, began to twirl it rapidly, at the same time exerting all possible downward pressure. As his hands moved towards the lower end of the spindle he dexterously shifted them back to the top, without lifting it or allowing air to get under its lower end.

With the continuation of the twirling process a tiny stream of wood meal, ground off by friction, poured through the slot at the side of the hearth, and accumulated in a little pile, that all at once began to smoke. In two seconds more it was a glowing coal of fire. Then Yim dropped his spindle, covered the coal with a bit of tinder previously made ready, and blew it into a flame, which he deftly transferred to the wick of his lamp.

At sight of the first spiral of smoke our lads had been filled with amazement. As the coal began to glow they uttered exclamations of delight, and when the actual flame appeared they broke into such enthusiastic cheering as set all the dogs to barking in sympathy.

"It is one of the most wonderful things I ever saw," cried Cabot. "I've often read of fire being produced by wood friction, and I have tried it lots of times myself, but as I never could raise even a smoke, and never before met any one who could, I decided that it was all a fake got up by story writers."

"I was rather doubtful about it myself," admitted White. "But, I say! Isn't that a great lamp, and doesn't it make things look cheery?"

White's approval of "Yim's cook stove," as Cabot called it, was well merited, for its five inches of blazing wick yielded as much light and twice the heat of a first-class kerosene lamp. Over it Yim had already suspended a kettle full of snow, and now he laid a slab of frozen pork close beside it to be thawed out.

While waiting for these he fed the dogs, who had been watching him with wistful eyes and impatient yelpings. To each he threw a two-pound chunk of frozen walrus meat, and each devoured his portion with such ravenous rapidity that Cabot declared they swallowed them whole.
