The parley that followed was of course unintelligible to our adventurers, the Boy Slaves.

But although they did not understand the words that were exchanged between the two sheiks, they were not without having a conjecture as to their import. The gestures made by the two men, and their looks cast frequently towards themselves, led them to believe that the conversation related to their transference from one to the other.

There was not much to choose between the two masters. Both appeared to be unfeeling savages, and so far had treated their captives with much cruelty. They could only hope, in case of a transfer taking place, that it would not be partial, but would extend to the trio, and that they would be kept together. They had been already aware that old Bill was to be parted from them, and this had caused them a painful feeling; but to be themselves separated, perhaps never to meet again, was a thought still more distressing.

The three youths had long been shipmates,—ever since entering the naval service of their country. They had become fast friends; and believed that whatever might be the fate before them, they could better bear it in each other's company. Companionship would at least enable them to cheer one another; mutual sympathy would, to some extent, alleviate the hardest lot; while alone, and under such cruel taskmasters, the prospect was gloomy in the extreme.

With feelings of keen anxiety, therefore, did they listen to the palaver, and watch the countenances of their captors.

After a full half-hour spent in loud talking and gesticulating, some arrangement appeared to have been arrived at between the two sheiks. Those most interested in it could only guess what it was by what followed.

Silence having been partially restored, the old Arab was seen to step up to the spot where the slaves of the black sheik were assembled; and, after carefully scrutinizing them, pick out three of the stoutest, plumpest, and healthiest young negroes in the gang. These were separated from the others, and placed on the plain some distance apart.

"We're to be exchanged," muttered Terence, "we're to belong to the ugly black nagur. Well, perhaps it's better. We'll be with old Bill."

"Stay a wee," said Colin; "there's something more to come yet, I think."

The black sheik at this moment coming up, interrupted the conversation of the captives.

What was he going to do? Take them with him, they supposed. The old Arab had himself led out the three young "darkies"; and the black sheik was about to act in like manner with the trio of white captives.

So reasoned they; and, as it was a matter of indifference to them with which they went, they would offer no opposition.

To their chagrin, however, instead of all three, only one of them was led off; the other two being commanded by gestures to keep their ground.

It was O'Connor to whom this partiality was shown; the black sheik having selected him after a short while spent in scrutinizing and comparing the three. The Irish youth was of stouter build than either of his shipmates; and this, perhaps, guided the black sheik in making his choice. By all appearances, the conditions of the exchange were to be different from what our adventurers had anticipated. It was not to be man for man, or boy for boy; but three for one,—three blacks to a white.

This was, in reality, the terms that had been agreed upon. The avaricious old Arab, not caring very much to part with his share of the spoil, would not take less than three to one; and to this the black sheik, after long and loud bargaining, had consented.

Terence was led up, and placed alongside the three young darkies, who, instead of taking things as seriously as he, were exhibiting their ivories in broad grins of laughter, as if the disposal of their persons was an affair to be treated only as a joke!

Our adventurers were now apprehensive that they were to be separated. Their only hope was that the bargaining would not end there; but would extend to a further exchange of six blacks for the two remaining whites.

Their conjectures were interrupted by their seeing that the "swop" was not yet considered complete.

What followed, in fact, showed them that it was not a regular trade at all; but a little bit of gambling between the two sheiks, in which Terence and the three young blacks were to be the respective stakes.

Old Bill was able to explain the proceedings, from his experience of the preceding night; and as he saw the two sheiks repair to the place where his own proprietorship had been decided, he cried out:—

"Yere goin' to be gambled for, Masther Terry! Och! ye'll be along wid me,—for the black can bate the owld Arab at that game, all hollow."

The holes in which the helga had been played on the preceding night were now resorted to. The proper number of dung pellets were procured, and the game proceeded.

It ended as the old man-o'-war's-man had prognosticated, by the black sheik becoming the winner and owner of Terence O'Connor.

The Arab appeared sadly chagrined, and by the way in which he strutted and stormed over the ground, it was evident he would not rest satisfied with his loss. When did gamester ever leave gaming-table so long as a stake was left him to continue the play?

Two of the midshipmen still belonged to the old sheik. With these he might obtain a revanche. He made the trial. He was unfortunate, as before. Either the luck was against him, or he was no match at "desert draughts" for his sable antagonist.

It ended in the black sheik becoming the owner of the three midshipmen, who, restored to the companionship of Sailor Bill, in less than twenty minutes after the conclusion of the game, were trudging it across the desert in the direction of Timbuctoo!
