CHAPTER XXXIX
DANGERS OF THE SUMMER FORDS
Two more days were occupied in ascending the valley of the Alsek to its headwaters. The trail crossed many tributary streams, through which our pedestrians were obliged to wade, and twice it was necessary to cross the Alsek itself. Although the stream was here much narrower and shallower than at Dalton's Post, its current was still so turbulent that on each occasion the Bradfords took advantage of the pack train. Not infrequently they saw the bodies of horses and cattle which had either become hopelessly mired or had broken a leg among the rocks, and been shot and abandoned by their owners.
Beyond Rainy Hollow the summer trail was quite independent of the winter one, and led across a bleak summit now devoid of snow save the grimy remains of a few old drifts. Here they were startled by a sudden deep booming and thundering which seemed to proceed from nowhere in particular. The boys thought it an earthquake, but Uncle Will said he had no doubt the noise was similar to those they had heard in that vicinity in March, and was occasioned by a tremendous avalanche or the disintegration of a glacier on the lofty peaks across the Klaheena.
On the highest point of the pass they met an inbound pack train belonging to the Thirty-six, in charge of one Paddock.
"Is this the Bradford party?" asked Paddock, as he came up. On being assured that it was, he continued, "I was on the lookout for you. I met Bud Beagle's outfit about an hour ago, and he said you was close behind. I've got some mail for you."
He fumbled in an inner pocket of his coat, which was tied to the pommel of his saddle, and presently extracted a little bundle of letters, which he handed to Mr. Bradford.
"Mebbe there ought to be more," he said with a trace of embarrassment, "but the fact is, we lost a hoss in the Klaheena River. He carried one o' the mail-bags, besides all our cooking outfit and consid'rable provisions."
"Lost the horse?" said Mr. Bradford. "How did that happen?"
"Well, you see, sir," explained Paddock, "that hoss got sep'rated from the others when we crossed the river, and he struck a deep hole. His load was jest heavy enough so he couldn't swim, and away he went. We follered along the bank for two good miles, but didn't find him."
