“Look out!” I cried, as I gulped down the last of my coffee, “there’s something going on there.”

The clamour grew louder and louder till it seemed to fill the skies with a concentrated noise of curses and shrieking. Distinct from it, as it were, I heard shouts of alarm and rage, and then came the sounds of gunshots, yells of agony and the thud of many running feet. By now the light was growing fast, as it does when once it comes in these latitudes. Three more minutes, and through the grey mist of the dawn we saw dozens of black figures struggling up the slope towards us. Some seemed to have logs of wood tied behind them, others crawled along on all fours, others dragged children by the hand, and all yelled at the top of their voices.

“The slaves are attacking us,” said Stephen, lifting his rifle.

“Don’t shoot,” I cried. “I think they have broken loose and are taking refuge with us.”

I was right. These unfortunates had used the two knives which our men smuggled to them to good purpose. Having cut their bonds during the night they were running to seek the protection of the Englishmen and their flag. On they surged, a hideous mob, the slave-sticks still fast to the necks of many of them, for they had not found time or opportunity to loose them all, while behind came the Arabs firing. The position was clearly very serious, for if they burst into our camp, we should be overwhelmed by their rush and fall victims to the bullets of their captors.

“Hans,” I cried, “take the men who were with you last night and try to lead those slaves round behind us. Quick! Quick now before we are stamped flat.”

Hans darted away, and presently I saw him and the two other men running towards the approaching crowd, Hans waving a shirt or some other white object to attract their attention. At the time the foremost of them had halted and were screaming, “Mercy, English! Save us, English!” having caught sight of the muzzles of our guns.

This was a fortunate occurrence indeed, for otherwise Hans and his companions could never have stopped them. The next thing I saw was the white shirt bearing away to the left on a line which led past the fence of our boma into the scrub and high grass behind the camp. After it struggled and scrambled the crowd of slaves like a flock of sheep after the bell-wether. To them Hans’s shirt was a kind of “white helmet of Navarre.”

So that danger passed by. Some of the slaves had been struck by the Arab bullets or trodden down in the rush or collapsed from weakness, and at those of them who still lived the pursuers were firing. One woman, who had fallen under the weight of the great slave-stick which was fastened about her throat, was crawling forward on her hands and knees. An Arab fired at her and the bullet struck the ground under her stomach but without hurting her, for she wriggled forward more quickly. I was sure that he would shoot again, and watched. Presently, for by now the light was good, I saw him, a tall fellow in a white robe, step from behind the shelter of a banana-tree about a hundred and fifty yards away, and take a careful aim at the woman. But I too took aim and—well, I am not bad at this kind of snap-shooting when I try. That Arab’s gun never went off. Only he went up two feet or more into the air and fell backwards, shot through the head which was the part of his person that I had covered.

The hunters uttered a low “Ow!” of approval, while Stephen, in a sort of ecstasy, exclaimed:
