"The fire is a hot un," he said at length, "and it runs three feet to our two. We may git there ahead of it, for there isn't more than a mile furder to go; but--Lord!" exclaimed the trapper, "how it roars! and it makes its own wind as it comes on. Don't break yer paddle shaft, boy; but the shaft is a good un and ye may put all the strength into it that ye think it will stand." The spectacle on which the trapper was gazing was, indeed, a terrible one; and the peril of the two men was getting to be extreme. The valley, through the centre of which the river ran, was perhaps a mile in width, at which distance a range of lofty hills on either side walled it in. Down this enclosed stretch the fire was being driven by a wind which sent the blazing evidences of its approach in advance of its terrible progress. The spectacle was indescribable. The dreadful line of flame moved onward like a line of battle, when it moves at a charge against a flying enemy. The hungry flames ate up the woods as a monster might eat food when starving. Grasses, shrubs, bushes, thickets of undergrowth and the great trees, which stood in groves over the level plain on either side of the stream, disappeared at its touch as if swallowed up. The evergreens crackled and flamed fiery hot. The smoke eddied up in rushing volumes. Overhead, and far in advance of the on-rolling line of fire, the air was darkened with black cinders, amid whose sombre masses fiery sparks and blazing brands shone and flashed like falling stars. [Illustration: "_A deer suddenly sprang from the bank._"] A deer suddenly sprang from the bank into the river ahead of the boat and, frenzied with fear, swam boldly athwart its course. He was followed by another and another. Birds flew shrieking through the air. Even the river animals swam uneasily along the banks, or peered out of their holes, as if nature had communicated to them, also, the terrible alarm; while, like the roar of a cataract,--dull, heavy, portentous,--the wrath of the flames rolled ominously through the air. Amid the sickening smoke which was already rolling in volumes over the boat and the terrible uproar and confusion of nature, Herbert and the trapper kept steadily to their task. But every moment the line of fire gained on them. The smoke was already at intervals stifling and the heat of the coming conflagration getting unbearable. Brands began to fall hissing into the water. Twice had Herbert flung a blazing fragment out of the boat. And so, in a race literally for life, with the flames chasing them and their lives in jeopardy, they turned the last bend above the carry which began at the head of the rapids. But it was too late; the fiery fragments blown ahead by the high wind had fallen in front of them, and the landing at the carry itself was actually enveloped in smoke and flame.
