“What!” exclaimed Terence; “have you been a slave in the Saara so long as that? If so, God help us! What hope is there of our ever getting free?”

The young Irishman spoke in a tone of despair.

“Very little chance of your ever seeing home again, my lad,” answered the invalid! “but I have a chance now, if you and your comrades don’t spoil it. For God’s sake don’t tell these Arabs that they are the fools they are, for making salvage of the ballast! If you do, they’ll be sure to make an end of me. It’s all my doing. I’ve made them believe the stones are valuable, so that they may take them to some place where I can escape. It is the only chance I have had for years, don’t destroy it, as you value the life of a fellow-countryman.”

From further conversation with the man, our adventurers learned that he had been shipwrecked on the coast many years before, and had ever since been trying to get transported to some place where he might be ransomed. He declared that he had been backward and forward across the desert forty or fifty times; and that he had belonged to not less than fifty masters!

“I have only been with these fellows a few weeks,” said he, “and fortunately when we came this way we were able to tell where the sunken ship was, by seeing her foremast then sticking out of the water. The vessel was in ballast; and the crew probably put out to sea in their boats, without being discovered. It was the first ship my masters had ever heard of without a cargo; and they would not believe but that the stones were such, and must be worth something, else why should they be carried about the world in a ship? I told them it was a kind of stone from which gold was obtained; but that it must be taken to some place where there was plenty of coal or wood, before the gold could be melted out of it, and then entrusted to white men who understood the art of extracting the precious metal from the rocks.

“They believe all this: for they can see shining particles in the sandstone which they think is really gold, or something that can be converted into it. For four days they forced me to toil, at diving and assisting them; but that didn’t suit my purpose; and I’ve at length succeeded in making them believe that I am not able to work any longer.”

“But do you really think,” asked Harry Blount, “that they will carry the ballast any distance without learning its real value?”

“Yes; I did think that you might take it to Mogador, and that they would let me go along with them.”

“But some one will meet them, and tell them that their lading is worthless?” suggested Colin.

“No, I think that fear of losing their valuable freight will keep them from letting any one know what they’ve got. They are hiding it in the sand now, as fast as they get it ashore; for fear some party stronger than themselves should come along and take it away from them. I intend to tell them after they have started on their journey, not to let any one see or know what they have, until they are safe within the walls of Mogador, where they will be under the protection of the governor. They have promised to take me along with them, and if I once get within sight of a seaport, not all the Arabs in Africa will hinder me from recovering my liberty.”
