It was not so dark as it had been. The light was increasing, it was that of the rising moon. They found that they had arrived in front of some palisades. They formed the wall to the negro city. Wasser signified that they must get over it to see their friend, and conducted them to the left, along the outside of the palisade. At last they got to a spot where he showed them that they might climb over, and whispered that there were no houses near whose inhabitants might discover them. The moon, as I was saying, was rising, so there was no time to be lost in reaching Jack's prison before the light might render the approach more difficult. Cautiously they crept on under the shadow of the houses. The inhabitants appeared to be asleep. Now and then a dog barked, but they saw no one. At last, at the end of a street, they came to an open space, in which stood a solitary hut. Wasser pulled up, and said, "Dere your friend." How Alick's and Paddy's hearts longed to get at him! Their impulse was to run across the square and to let him out, but at that moment a sentry appeared from the other side of the hut with a musket on his shoulder. Though they did not fear the musket, they knew he might possibly let it off and alarm the town, so they stood under the dark shade of a wall, deliberating what was to be done. They watched him for some time, and ascertained that, like a clockwork figure, he always made the same round at the same pace. "We shall have time to get across the square and to seize him before he makes his round," observed Murray. Adair signified that he thought the same, as did Wasser. "Then," added Murray, "you and I, Paddy, will seize him, while Wasser lets Jack out of the prison, and he can come and help us bind and gag the sentry." "Now is our time," whispered Murray. "One, two, three, and away!" Down the square they dashed at full speed. Paddy leaped like a wild man of the woods on a sudden on the astonished sentry's back, and pressed his hand tightly over his mouth, while Murray grasped his musket, putting his hand on the pan, to prevent it going off (he need not have taken so much trouble, as it had no flint in it), while Wasser climbed up to the top of the hut, where he had ascertained there was a hole. It was his honest countenance Jack saw looking down upon him. Jack little thought all the time how near his friends were, and what essential service they were rendering him. Wasser put down his hand, and Jack catching it, Wasser, with a strong tug, enabled him to grasp some of the rafters. Jack very quickly was on the roof, and seeing two negro lads struggling with the sentry, guessing that they were in some way trying to serve him, leapt down to help them. The sentry had very little chance against four stout lads, and so they soon had him down and gagged, and dragged inside the hut. "Now run, run," whispered Wasser, "no moment lose."
