For some three hours the party moves forward through the forest shades. Then a halt is called, and, sentinels having been posted, soon the smoke of bivouac fires ascends, and the clatter of cooking utensils mingles with the hum of many voices.

The place selected is an open glade or clearing, overhung on one side by hoary masses of rock. The slave-hunters, as we have said, are divided into two sections, one consisting of negroid Arabs and Wa-Swahili, believers in the Prophet mostly, and clad in array once gaudy but now soiled and tarnished, some few, however, wearing the white haik and burnous; the other of Wangoni, stalwart, martial savages, believers in nothing and clad in not much more. These form camps apart, for at heart each section despises the other, though for purposes of self-interest temporarily welded. A few, but very few, are Arabs of pure blood.

One of these is now engaged in converse with the leader of the party. He is a tall, dignified, keen-faced man, with eyes as piercing as those of a hawk, and his speech is sparing. But if his words are few his deeds are many, and the name of Lutali—which, however, he makes no secret is not his real name—is known and feared at least as far and as thoroughly as that of the chief of the slavers himself.

For the latter, one glance at him is sufficient to show that if ever man was born to rule with firm but judicious hand such a gang of bloodthirsty freebooters it is this one. The vigour of his powerful frame is apparent with every movement, and the strength and fixity of will expressed in his keen dark face there is no mistaking. But the black, piercing eyes and bronzed features belong to no Arab, no half caste. He is a white man, a European.

Stay! To be accurate, there is just a strain of Arab in him; faint, indeed, as of several generations intervening, yet real enough to qualify him for mysterious rites of blood brotherhood with some of the most powerful chiefs from Tanganyika to Khartoum. And throughout the Congo territory, and many an equatorial tribe beyond, this man's name has been known and feared. No leader of slave-hunters can come near him for bold and wide-sweeping raids, the terror and unexpectedness of which, together with the complete and ruthless fixity of purpose wherewith the objects of them, however strong, however alert, are struck and promptly subjugated, have gained for him among his followers and allies the sobriquet of El Khanac, "The Strangler." But the reader—together with Johannesburg at large—knows him under another name, and that is "Pirate" Hazon.

"Is it prudent, think you, Lutali?" he is saying. "Consider. These Wajalu are a trifle too near the land of the Ba-gcatya. Indeed, we ourselves are too near it now, and a day's journey or more in the same direction is it not to run our heads into the jaws of the lion?"

"Allah is great, my brother," replies the Arab, with a shrug of the shoulders. "But I would ask, what have we, in our numbers and with arms such as these," gripping significantly his Express rifle, "to fear from those devil-worshippers armed with spears and shields—yea, even the whole nation of them?"

"Yet I have seen an army of the nation of which those 'devil-worshippers' are sprung, armed only with spears and shields, eat up a force three times as large as our own and infinitely better armed, I being one of the few who escaped. And 'The People of the Spider' cannot, from all accounts, be inferior to the stock whence they came."

Lutali shrugs his shoulders again.

"It may be so," he says, "yet there is a large village of these Wajalu which would prove an easy capture and would complete the number we need."

"Then let us chance it," is Hazon's rejoinder.

The Arab makes a murmur of assent and stalks away to his own people, while Hazon returns to where he has left his white colleague.

"Well, Holmes, according to Lutali, they are bent on risking it," he begins, throwing himself upon a rug and proceeding to fill a pipe.

"Are they? I'm not altogether glad, yet if it tends towards hurrying us out of this butchery line of business I'm not altogether sorry. I think I hate it more and more every day."

"It isn't a bad line of business, Holmes," returns Hazon, completely ignoring the smothered reproachfulness, resentment even, underlying the tone and reply. "Come, now, you've made a goodish bit of money the short time you have been at it. Anyhow, I want to know in what other you would have made anything like as much in the time. Not in fooling with those rotten swindling stocks at the Rand, for instance?"

"Maybe not. But we haven't realized yet. In other words, we are not safe out of the wood yet, Hazon, and so it's too soon to hulloa. I don't believe we are going to get off so easily," he adds.

"Are you going to get on your croaking horse again, and threaten us with 'judgments' and 'curses,' and all that sort of thing?" rejoins the other, with a good-humoured laugh. "Why, man, we are philanthropists—real philanthropists. And I never heard of 'judgments' and 'curses' being showered upon such."

"Philanthropists, are we? That's a good idea. But where, by the way, does the philanthropy come in?"

"Why, just here." Then, impressively, "Listen, now, Holmes. Carry your mind back to all the sights you have seen since we came up the Lualaba until now. Have you forgotten that round dozen of niggers we happened on, buried in the ground up to their necks, and when we had dug up one fellow we found we had taken a lot of trouble for nothing because he'd got his arms and legs broken. The same held good of all the others, except that some were mutilated as well. You remember how sick it made you coming upon those heads in the half darkness; or those quarters of a human body swinging from branches, to which their owner had been spliced so that, in springing back, the boughs should drag him asunder, as in fact they did? Or the sight of people feeding on the flesh of their own blood relations, and many and many another spectacle no more amusing? Well, then, these barbarities were practised by no wicked slave-raiders, mind, but by the 'quiet, harmless' people upon each other. And they are of every-day occurrence. Well, then, in capturing these gentle souls, and deporting them—for a price—whither they will perforce be taught better manners, we are acting the part of real philanthropists. Do you catch on?"

"What of those we kill? Those Wangoni brutes are never happy unless killing."

"That is inevitable and is the law of life, which is always hard. And, as Lutali would say, who may fight against his destiny? Not that I mean to say we embarked in this business from motives of philanthropy, friend Holmes; I only cite the argument as one to quiet that singularly inconvenient conscience of yours. We did so, Stanninghame and I, at any rate, to make money—quickly, and plenty of it; and I'm not sure Stanninghame doesn't need it more than you and I put together."

"By-the-by, I wonder what on earth has become of Stanninghame all this time?" said Holmes, apparently glad to quit an unprofitable subject.

"So do I. He ought to have joined us by now. He is just a trifle foolhardy, is Stanninghame, in knocking about so far afield alone," and a shade of anxiety steals over the speaker's face.

Holmes makes no reply, and for a while lies back on his rug, puffing away at his pipe and busy with his thoughts. These are not altogether pleasant. The process which had transformed the fine, open-natured, wholesome-hearted young Englishman into a slave-hunter, the confederate of ruthless cut-throats and desperadoes, had, in truth, been such as to engender the reverse of pleasant thoughts. Yet, that he had come to this was rather the fault of circumstances than the fault of Holmes. He had enjoyed the big game shooting and the ivory trading of the earlier stage of the trip, the more so from the consciousness that there was profit in both; and when a large caravan of the above and other legitimate merchandise had been run down to the coast, he had steadfastly refused to take the opportunity of parting company with the others. Then when they had pushed farther into the equatorial regions, and, joining with Lutali, had embarked on their present enterprise, all opportunity of withdrawing had gone. The precise point at which he had cast in his lot with this, Holmes could not with certainty define. Yet there were times when he thought he could. He had relieved his conscience with indignant, passionate protest, when first his eyes became fairly opened to the real nature of the enterprise; and then had supervened that terrible bout of malarial fever, his tardy recovery from which he owed entirely to the care and nursing of both Hazon and Stanninghame. But it left him for a long time weakened in mind and will no less than in body, and what could he do but succumb to the inevitable? Yet he had never entered into the sinister undertaking with the whole-heartedness of his two conscienceless confederates, and of this the latter were aware.

However, of his scruples they were tolerant enough. He was brimful of pluck, and seemed to enjoy the situation when they were attacked by overwhelming odds and had to fight hard and fiercely, such as befell more than once. And they would insidiously lay salve to his misgivings by such arguments as we have just heard Hazon adduce, or by reminding him of the fortune they were making, or even of the physical advantage he was deriving from the trip.

The latter, indeed, was a fact. The life in the open, the varying climates, frequent and inevitable hardships and never-absent peril, had made their mark upon Holmes. Once recovered from his attack, he began to put on flesh and muscle, and his eyes were clear and bright with that keen alertness which is the result of peril as a constant companion. In short, as they said, he looked twice the man he had done when lounging around the Stock Exchange or the liquor bars of Johannesburg.

Through the hot hours of noontide the raiders lie at their ease. Many are asleep, others conversing in drowsy tones, smoking or chewing tobacco. The Wangoni divide their time about equally between taking snuff and jeering at and teasing the unfortunate captives. These, crouching on the ground, relieved during the halt of their heavy forked yokes, endure it all with the stoicism of the most practical phase of humanity—the savage. No good is to be got out of bewailing their lot, therefore they do not bewail it; moreover, belonging to a savage race, and far from the highest type of the same, they have no thought of the future, and are thus spared the discomfort and anxiety of speculating as to what it may contain for them. Indeed, their chief anxiety at this moment is that of food, of which they would fain have more, and gaze with wistful eyes upon their captors, who are feasting on the remnant of what was until lately their own property. But the latter jeeringly suggest to them the expediency of their devouring each other, since they seem to have a preference for such diet.

Then, as the sun's rays abate somewhat in fierceness, the temporary camp is struck. Bearers take up their loads, fighters look to their arms, the soiled and gaudy finery of the semi-civilized sons of the Prophet contrasting with the shining skins of the naked Wangoni, even as the Winchester and Snider rifles and great sheath-knives and revolvers of the first do with the broad spears and tufted hide shields of the latter. And with the files of dejected-looking slaves, yoked together in their heavy wooden forks, or chained only, the whole caravan, numbering now some six hundred souls, moves onward.

But in the mind of the principal of the two white leaders, as he traces a cipher on the scene of their recent halt, and in that of the other, who watches him, is present, now with deepening anxiety, the same thought, the same speculation: What has become of the third?
