"Not that that matters. But I should like to know a little more. I am not marching against the Arabs; why are your friends so concerned about our operations against a native chief? What is the motive? Tell me that."

Relieved that the major's interrogation was no longer so uncomfortably personal to himself, the guide went on with his narrative.

Far away in the west, he said, beyond Imubinga, beyond the Rutchuru and the hills, in the heart of the Congo forest, his friends had a stronghold, so well hidden that the forces of the Congo Free State had never succeeded in finding it. Even if they had found it they would have failed to take it, for the place was absolutely impregnable. To this fortress a remnant of Arab dealers in ivory and slaves had retired when the power of Hamed ben Juna, more commonly known by the natives' nickname, Tippu Tib, and his lieutenants was broken by the Belgian forces, and there they still pursued their vocation by stealth, their spies marking every movement of the Free State officials, their allies drawing the enemy off when he came dangerously near. In the course of some years they had amassed a huge store of ivory, and collected some thousands of slaves, some of these latter being employed in tilling the soil and supplying their captors with the necessaries of life; while others were traded away for ivory to the cannibal tribes of the middle Congo. It was, however, becoming increasingly difficult to elude the Free State authorities, and the circle of their traffic was gradually narrowing. The old chief Rumaliza, whom the Belgians supposed to have died in the forest after the capture of Kabambari, was still alive, looking with alarm at the prospect of having to feed his horde of slaves without any chance of a profitable deal. Hemmed in by the British, German, and Free State territories, which were all being brought rapidly under effective control by the respective European administrators, he foresaw inevitable ruin, soon or late. He was anxious, therefore, to realize his wealth and retire to the coast, and in pursuance of this aim he had resolved on one final coup, a last expiring effort of the slave-trade. His plan was to form a huge caravan, transport all his slaves to the coast, and ship them to Arabia.

"Oh, come now!" exclaimed the major at this point, "that must be nonsense. It's close on a thousand miles to the nearest point of the coast, and your friends are not fools enough to imagine that they could make a slave run without having us upon their tracks."

Then the guide proceeded to unfold a plot at which his younger hearers held their breath, and even the major himself, old and seasoned hand as he was, could scarcely restrain an exclamation of astonishment. The Arabs, said the man, had in their camp a number of deposed Banyoro and Baganda chiefs, whose conduct had been such as to preclude any chance of their regaining their position while the British occupation continued. These men, having nothing to lose and everything to gain, had established communications with every Mahomedan in Uganda and Unyoro who was known to be disaffected. At a given signal the latter were to rise; and the signal was to be the defeat of a British column. Where the defeat was to take place had not been disclosed to the disaffected in Uganda, lest the plot should be divulged. It had been perfected by the Portuguese during his stay in Kisumu. It was known that only a weak British force was available for operations in the southern part of the Protectorate. A small native chief was to be persuaded to revolt, and it was hoped that the affair would be regarded as of so little consequence that only a handful of troops would be employed to crush him. The revolt had taken place as arranged, but owing to Major Burnaby's energy the punitive column was stronger than the Arabs had anticipated. Still, with a numerical advantage of two to one, without counting their native allies and dependants, the Arabs were not so much disheartened as to abandon their plans. They confidently expected that the ambush would result in the annihilation of the British force. The news was to be conveyed to the scattered conspirators with the rapidity with which news always flies through native Africa; a picked force was to seize rail-head, after overpowering, or at least harassing, the small garrisons at Entebbe, Kisumu, and other military stations, and, if possible, to foment a general rising among the populace. Taking advantage of the confusion, the Arabs, with their satellites, were to run the slaves by forced marches to the western shore of the Nyanza, carry them over in canoes, and thence for a hundred and fifty miles along the railway, and then make for a spot on the coast of Italian Somaliland, whence they could ship them to Arabia.

"'Faith, I would like to examine the cranium of the man who devised that crazy scheme!" cried the doctor. "He must be's mad's a hatter!"

The major was in no mood to indulge in quips with Dr. O'Brien. His mind was wholly concentrated on the task which had opened before him. He sat silent and abstracted, seeming even to have forgotten the presence of the traitor. Recovering himself in a moment, he said quietly:

"Go away. You will be kept under arrest for the rest of the march; see to that, Mr. Mumford. When we are through with this business I'll consider what's to be done with you. Take him away. There's the other man now," continued the major, when the guide had been removed. "It is just worth while to see if his story corroborates the one we have just heard. Fadl, fetch the captured slave."

It was short work with him. A rumour had already run through the camp that the guide was in trouble, and the Ankoli wore an anxious look when he came up. The major told him in one sentence that his friend Munta had confessed; and the man at once volunteered to unbosom himself. His story differed from the other merely in ornaments. To the major's enquiries he replied that the Arabs were about nine hundred and fifty strong, and their allies rather more than a thousand. Many of the former were armed with Mausers, smuggled in through German East Africa. The rest of them had Sniders and other obsolete rifles ("Good enough in forest fighting" was the practical remark of Captain Lister), while the Manyema for the most part had only very old muskets in addition to spears.

"That rings true," said the major. "Has he anything more to tell?"
