"The poles are our only chance," said Nicholas, and, quickly as thought, they fastened their poles to the sides, so that they stretched out like two great arms. "Let us but keep our whole weight steadily upon the handles, and we may keep her course straight," said Nicholas; and no sooner had they thrown themselves across the poles than a noise like that of distant thunder rumbled through the air; it was the great tide wave rolling like a mountain toward them. Now they could not escape; so, commending their souls to Heaven, they awaited its approach with suspended breath. It came, and, with a roar, caught up the boat, carrying it to a height of fifty feet; in another second the boys were covered with a cold sweat at the narrowness of their escape, which had been owing to their precaution. Then followed a calm, as if the anger of the watery element had subsided. The boys slackened their hold of the poles, and so they continued for two hours, going they knew not whither. Suddenly the boat began to rock. "To your pole, Chow," cried Nicholas. No sooner had he complied, than they found they had entered upon a rapid, for the little craft shot forth almost with the velocity of an arrow. Then came the first faint streaks of daybreak, and they trembled, for they saw that they had entered a narrow creek. "Steady, for our lives, there is hope yet, for yonder vessel may see us," said Nicholas. The vessel to which he alluded was a large junk, so skilfully handled that she seemed to be stemming the torrent. Gaining hope, the boys clung to their only chance, namely, keeping the poles in their fixed positions. Another half hour, however, and their strength became exhausted, the poles quivered, the boys felt they could not hold out much longer; still another determined effort; their minds lent strength to their limbs. Then the first light of the sun, an eastern sun, shone upon the junk, and disclosed a huge painted eye (the government emblem), at the sight of which, and screaming aloud "The yah-yu!" Chow let go his hold, fell backward, and one pole being thus released, the boat lost its equilibrium, the pole of Nicholas snapped, and she swang round like a Catherine wheel. They were in a whirlpool--nothing could save them--then came a fearful crash, and neither Chow nor Nicholas could distinguish more. CHAPTER XII. NICHOLAS AGAIN TAKEN PRISONER.
