They turned in late and when they awakened, Olaf and Lafe had taken their leave without disturbing them. They had left a scribbled note of thanks, however, with their best wishes for good luck.
"I shall never forget Olaf Gundersen," declared Tom, a sentiment which the rest echoed.
[CHAPTER XXIV.]
ON THE PORCUPINE RIVER.
We must now pass over an interval of several weeks. During this period our readers are to imagine the numerous rapids and perils of the Upper Yukon conquered and the permanent camp of the silver fox hunters established upon the swift Porcupine River, not far above its junction with the Yukon and amidst a country wilder than any into which the Bungalow Boys had yet penetrated.
The work of setting out the peculiarly constructed traps in which the silver and black foxes were to be trapped had occupied much time, and some exciting adventures with bears and wolves had accompanied the work. When completed, the "trap-line" extended for more than twenty-five miles from the camp, which was pitched on the bank of the river to which the Yukon Rover was tied.
Did space permit we should like to tell in detail, and may at some future time, the numerous exciting episodes that marked those weeks of our young friends' lives. But we must now hasten on to an event which was to try their resources as they had rarely been tested before, and which was peculiarly characteristic of the life in that wild region "north of fifty-three" which they were exploring.
It is first necessary to explain that the work of overseeing the trap-line was attended to every week, the work being divided into "shifts," one of the party, or more, being left to guard the camp during the absence of the others. At the particular time we are now dealing with Mr. Dacre was disabled with a slight fever, and Sandy, also, was a "little under the weather" from the same cause. So that it devolved upon Tom and Jack to assume the task of going over the trap-line, a duty which had to be performed, while Mr. Chillingworth remained behind with the invalids.
