"I should not be surprised if they tried to-night. Shall I bring ten of the men on shore at once, sir?"

"Well, perhaps it would be as well. Forty men are not a very large force for this length of palisade and to work some of the guns at the point where they may attack us, and I expect their first rush will be a serious one, and we shall have all our work cut out for us. There is one thing; we can rely, in case of their making a way in, on the slaves. By this time they quite understand that we are friends and that the people who had been firing on us are their enemies, and I believe they would fight like demons rather than fall into their hands again. I have torn up a bale of white calico and have given a strip of it to each man to tie round his head, so that we can tell friend from foe and they can recognize each other in the dark. The enemy won't reckon on that, and will think that they have only a small body of whites to deal with. Do you notice how silent the woods are now? I think we may take that as a sign that they are preparing for mischief."

"The sooner it comes the better. Have you plenty of port fires, Mr. Playford?"

"Yes, a large boxful came on shore with the last boat yesterday."

Nat went off again, and picked out ten men to land with him.

"Get the other boat down," he said to the petty officer. "You will understand that if any attack is made on the flanks of the work you are to open fire at once upon them with grape. If a blue light is burned at the edge of the water ten men are to land instantly. You will remain in charge of the other five. So far as we know they have no boats, but they may have made a raft, and may intend to try and take the schooner, thinking that the crew will probably be on shore. So you must keep a sharp look-out on the other side as well as this. Light a blue light if you see a strong party coming off, and we will rejoin you at once."

He again landed with the ten men he had chosen.

"I have six men on watch," the lieutenant said, "and have put one of the blacks with each. I fancy their ears are sharper than ours are, and they will hear them coming before our men do."

Having nothing to do, Nat went into the barracoon and the other houses in which the slaves were placed. The contrast between their condition now and when he had seen them four days before, when they had first been found, was striking indeed. Now they were clean, and looked picturesque in their bright calico clothes. The look of dull and hopeless misery had passed away, and it seemed to him that with the good and plentiful food they had received they were already perceptibly plumper. They would have risen as he entered, but he signed to them to keep their places. They now had room to lie down in comfort, and while some sat chatting in groups others moved about. They were evidently proud of their arms, and some of them, seizing their pikes or hatchets, made signs how they would fight their enemies. A ship's lantern was burning in each hut.

In the women's huts the scene was still more interesting. The little children ran up to Nat with a new-born confidence in white men. Some of the women brought up babies to show him, and endeavoured to make him understand that these would soon have died had it not been for the sailors. The windows and doors stood open, and the evening breeze cleared the huts of the effluvium always present where a number of negroes congregate together. The sight of the poor creatures enraged Nat still more against the slavers, and made him long for them to begin their attack.
