The reply was followed by another shot from the slave-hunters; but the ball whistled far above the heads of the fugitives. Dan took deliberate aim at the boat, and fired, ordering Quin to do the same. So far as they could discover, neither of the shots took effect. From this time both parties kept up an occasional firing; but as the night was so dark, and the motion of the boats not favorable to a steady aim, no one in the Isabel was hit, and Dan and his companion were not aware of any different result to the other boat. Cyd maintained his position at the helm with the steadiness of an old salt who had stood at the wheel in a hundred battles; and Dan, witnessing his improved demeanor, began to think his singular conduct had been the result of excitement rather than of timidity. But one thing was painfully evident to all on board of the schooner--that the boat was gaining upon her, and that the wind was gradually dying out. There was no hope for them except in their own right arms. They must fight for liberty, fight for the rights which they had boldly reaessumed. Dan and Quin were fully determined upon this course, and if they could bring Cyd up to a sense of duty on this trying emergency, there would be some chance of success. As it was, the odds were against them. The pursuers were probably men accustomed to the use of arms, while all in the Isabel were, to say the least, very indifferent marksmen. Hitherto, they had fired at a dark mass on the water, for they could not distinguish the enemy in the gloom of the night, and the pursuers had been subject to the same disadvantage. A nearer approach to each other of the contending parties, would enable both to obtain a more accurate aim, and the work of death could not be much longer postponed. "De wind's clean gone," said Cyd, as the heavy sails of the Isabel began to flap idly in the brails. "Cyd, you must fight!" added Dan, earnestly. "Possifus!" exclaimed Cyd, rising and seizing a boat-hook that lay on the quarter. "Dis chile will fight, for sartin." "Good, Cyd! You are a brave fellow! You deserve to be free, and you shall be." "Hossifus! Don't tell Cyd he's a coward, kase he ain't no such ting, no how." "I didn't mean that, Cyd; and I take it all back," added Dan. "The boat has lost her headway now. They will be upon us in a moment or two. Stand firm, Cyd, and break the head of any man that attempts to get into the boat." "Yes, sar! Dat's jus what I'se gwine to do. I'll broke de head ob any nigger-hunter dat's gwine to come in dis boat, for sartin." "Now, stoop down both of you, and let them fire over our heads as they come up."
