"Now, kid," said Waseche Bill the following morning, "we got to make tracks fo' the Tatonduk. We got too many dogs, an' we got to cut down on the feed. I hate to do it—on the trail—but they's no two ways about it. Three or fo' days ort to put us at the divide. I made a cache the'h comin' in an' we'll be all right when we strike it."

The two stood in front of the cavern, breathing deeply of the clear, pure air. A stiff breeze was blowing from the south-west, and the day was warm and pleasant. The sun had not yet risen, and as the dogs swung into the trail Connie glanced at the little thermometer lashed firmly to the back of his sled. It registered twenty degrees below zero, an ideal temperature for trail travel and the boy cracked his whip and yelled aloud in the very joy of living.

At the mouth of the canyon they swerved in a north-westerly direction, toward the northernmost reach of the Ogilvie Range. All day they mushed across the wide caribou barrens and flat tundra that separated the great nameless range behind them from the high mountains to the westward that lay between them and Alaska. For, upon ascending the Tatonduk, they had passed out of Alaska into the unmapped Yukon district of sub-arctic Canada. Evening of the second day found them among the foothills of the mountains. Patches of stunted timber appeared and the lay of the land forced them to keep to the winding beds of frozen creeks and rivers. The end of the next day found them camped on the snow-covered ice of a small river. Waseche divided the few remaining fish, threw half of them to the dogs, and sat down beside the boy, who had prepared a meal of caribou charqui and coffee:

"Seems like this must be the creek—but I ain't sho'. I thought the one we tackled yeste'day was it, too—but it petered out on us."

"I don't know," replied Connie, "I thought I'd remember the back trail, but since the big snow everything looks different. And I was in an awful hurry to catch up with you, besides."

"Sho', kid, I know. I'd ort to took mo' pains myself, but I wasn't so pa'ticlah about gettin' back—then. Anyways, we'll try this one. We got to watch the grub now, fo' sho'. Them malamutes is hongry! Day afteh tomorrow, if we don't find the cache, we'll have to kill a dawg." Connie nodded.

"We'll find it, all right. This looks like the creek. Still, so do they all," he added reflectively.

The next day was a repetition of the day preceding. They followed the bed of the creek to its source in a narrow canyon which lost itself upon the steep side of a gigantic mountain. Wearily, they retraced their steps and once again among the foothills, turned to the northward.

"They's no dodgin' the truth, son," said Waseche gloomily, as they mushed on, scrutinizing the mouths of creeks in a vain endeavour to locate a landmark. "We're lost—jest na'chly plumb lost—like a couple of chechakos."

"The divide's somewhere," answered the boy, bravely. "We'll find it."
