“If we had not captured those slavers some time back, I should be inclined to believe that there is no such thing as the slave trade on this coast,” exclaimed Rhymer, as he sat in the tent one evening after sunset. “It is all my ill-luck, however, and I suppose I shall get hauled over the coals for my want of success. If we catch sight of another dhow, and she takes to flight, I’ll chase her round the world rather than lose her.”

Next morning, soon after Ned had gone up to the look-out station, as he was turning his glass to the southward, the white canvas of a dhow, lighted up by the rays of the rising sun, came full into view, standing almost directly for the island. The wind for the last day or two had been variable. It was now blowing from the south-east. Quickly descending, he carried the information to his commanding officer. The party, tossing off their coffee, and snatching up the portions of breakfast they had just commenced, hurried on board. By the time they had got clear of the island the hull of the dhow could be seen. For some time she stood on as before, apparently not discovering them. With the wind as it had been, she had no chance of escaping, except by running on shore, and Rhymer ordered his men to lay on their oars to await her coming, while the sail was got ready to hoist in a moment, and the gun loaded to send a shot at her should she refuse to strike. Presently the wind shifted two points to the eastward, the dhow lowered her sail.

“Hurrah!” exclaimed Rhymer; “she knows it’s of no use to try and escape. We will make sail, and shall soon be up to her. Hoist away!”

The boat was soon under canvas, heeling over to the freshening breeze. A short time, however, only had elapsed when the dhow was seen to rehoist her sail; but it was evident from her position that her head had been brought round, and was now pointing to the southward.

“It is pretty clear that the Arabs intend to run for it,” observed Charley to Ned.

“And if they go round the world we shall have to follow them,” answered Ned in a low voice.

The boat sailed well. There was just enough wind, and no more, to suit her, and the dhow apparently was not so fast a sailer as some of her class. Still she kept well ahead of the boat. Should the wind shift back to its old quarter, however, there was a fair probability that the boat would overtake her.

“We’ve got a good many hours of daylight, and it will be a hard matter if we do not come up with her before dark,” said Rhymer.

“But as it is, if we do not, and we are to chase her round the world, we must do our best to keep her in sight during the night,” observed Charley, demurely.

The dhow was still out of range of the boat’s gun, and appeared determined to stand on while there was a prospect of escaping. The wind continuing as before, Ned and Charley began to fear that after all she would get away.
