"we're doing well," observed tim mccabe, when the raft with its load and party of gold-seekers reached the end of lynx river, "but be the same token, we're drawing nigh the worst part of the voyage, and we'll be lucky if we git through the same without mishap."

"what have we ahead?" asked jeff.

"miles cañon; it's a little more than half a mile long, and if this raft isn't as strong as it should be it'll be torn to pieces."

fortunately jeff had given attention from the first to the stability of the structure, upon which everything depended. he was continually examining it from stem to stern, and where there was a suspicion of the necessity, he drove nails and strengthened the craft in every way possible.

the sail was used whenever possible; but since they were really among the network of lakes which form the headwaters of the yukon, the current carried them steadily toward their destination, and there were hours when they scarcely lifted their hands except to keep the raft in proper position by means of the poles. the weather grew steadily milder, for summer was approaching. the snow and ice rapidly melted, and now and then, when the sun shone, the thick clothing felt uncomfortable during the middle of the day. our friends were in advance of the great multitude that were pushing toward the klondike from the south, from canada and to st. michael's, whence they would start on the two-thousand-mile climb of the yukon, as soon as it shook off its icy bounds.

it was impossible that the party should not view with solicitude their entrance into miles cañon, though tim assured his friends that much more dangerous rapids would remain to be passed. the cañon is five-eighths of a mile long, with an angry and swift current. although the raft was tossed about like a cockleshell, it went through without injury, and none of the goods were displaced or harmed.

following this came the severest kind of work. for three miles it seemed as if the river could be no worse, and the raft must be wrenched asunder. the current was not only very swift, but the channel was filled with rocks. each man grasped one of the strong poles with which the craft was provided, and wrought with might and main to steer clear of the treacherous masses of stone which thrust up their heads everywhere. there were many narrow escapes, and despite the utmost they could do, the raft struck repeatedly. sometimes it was a bump and sheer to one side so suddenly that the party were almost knocked off their feet. once, owing to unintentional contrary work the raft banged against the head of a rock and stood still. while the men were desperately plying their poles the current slewed the craft around, and the voyage was resumed.

the current was not only very swift, but the channel was filled with rocks.

the current was not only very swift, but the channel was filled with rocks.

"look out!" shouted jeff; "there's another rock right ahead!"

unfortunately it was just below the surface, and there were so many ripples and eddies in the current that neither tim nor hardman was sure of its exact location, but taking their cue from the leader, they pushed with all their strength to clear the obstruction.

they failed, and the flinty head swept directly under the logs and gouged its course for the entire length of the craft. all felt the jar, and those who could look beneath the upper deck saw the lower timbers rise from the impact, which was so severe that when the raft at last swung free it was barely moving, but, like a wounded horse, it shook itself clear, and the next moment was plunging forward as impetuously as ever. the fears of the party were intensified by sight of wreckage along the banks, proving that more than one of their predecessors had come to grief in trying to make the passage.

while all were on edge with the danger, however, they found themselves at the end of the perilous passage and floating in comparatively smooth water again. men and boys drew sighs of relief, the former mopping their perspiring brows and looking their mutual congratulations.

"the fun is only just begun," said tim mccabe; "we had matters purty lively fur a time, but they'll soon be a good deal livelier."

"what is next due?" asked frank.

"i belave," said tim, "that some folks spake of death as riding on a pale horse, don't they?"

"yes."

"that must be the raison they call the nixt plisure thramp white horse cañon, or white horse rapids."

"where are they?"

"but a little way ahid; many men have been drowned in thrying to sail through the same; and him as doesn't know how to swim in a whirlpool hasn't ony business to thry it."

"what, then, do you mean to do?"

"thry it," was the imperturbable response.

such talk was not calculated to cheer the listeners, but knowing the irishman as they did, they received his statement with less seriousness than they should have done, for he had by no means overrated the peril in their front. jeff made another examination of the raft while he had the opportunity, and strengthened it in every possible way. he was pleased that it stood the test so well, though it had been severely wrenched, and when it crawled over the sunken rock it had narrowly missed being torn asunder. the fastenings of the goods were examined and everything prepared, so far as it could be done, for the crucial trial at hand.

the party were seated in various positions about the raft, looking anxiously ahead, when tim pointed a little way in advance, with the question:

"do ye all obsarve that?"

he indicated a high bank of sand on the right which had been cut out by the erosion of the violent current. near by some philanthropist had put up a sign, "keep a good look out."

"you have larned what other people think of the same," he added; "there's been more than twinty men drowned in there."

"because they could not swim?" asked frank.

"'cause the best swimmer in the world can't swim in there; you and mesilf, boys, will soon be on the same futting, for the raison that we won't have any futting at all."

"how long is the cañon?"

"not quite half a mile. miles cañon, that we've just passed through, is like a duck-pond alongside the rapids in front of us."

"can a boat go through?"

"the thing has been done, but only about one in fifty that starts into them rapids ever raiches the outlet, excipt in bits the size of yer hand."

frank and roswell looked at each other in consternation. was it possible that jeff would allow the criminal recklessness tim contemplated? where the chances were so overwhelmingly against success, it was throwing away their lives to trust themselves to the fearful rapids that had already caused so many deaths.

"if you want to try," said roswell, excitedly, "you may do so, but neither frank nor i will. put us ashore!"

he addressed himself to jeff, who was seated on the edge of the upper deck, calmly smoking his pipe. he did not look around nor seem to hear the appeal.

"never mind," interposed frank; "if they are willing, we are not the ones to back out. i know of no law that prevents a man making a fool of himself."

"very well," replied his cousin, more composedly, "i am ready."
