The muster was complete. Amid a tremendous clamour the war-party moved towards the gate. With a sinking of the heart John guessed at their number: there must be three or four hundred. They marched out, the Swahili among them, leaving two of his party evidently to keep a watch on the prisoners--or the prisoner, for where was Bill? They had of course recognized him as a Wanderobbo: had they butchered him at once? No: there he was, at the entrance of a small hut thirty yards away. John took courage at the sight of him. If he was spared, it must be because, being employed by white men, he might have some commercial value. It occurred to John now that Juma, the prime mover in these machinations, would probably stop short of the actual murder of a white man, and might hold him to ransom. But this did not relieve his anxiety about Ferrier. The young Canadian would certainly not yield without a struggle, and in that struggle he might well lose his life. The two men left on guard tied his hands again and took him back to his hut. John made them understand by signs that he did not wish to be cooped up in its foetid atmosphere, and they let him sit at the entrance, standing close by with their spears. He saw now that he was at the highest part of the village, overlooking a vast expanse of the lower country. There was the war-party, already a dark blot amid the green. He could see the river winding its way for miles and miles over the plain, until it became little more than a silver streak in the sunlight. Was it his fancy, or did he descry in the far distance the island like a black spot on a silver plate? Suddenly he remembered that he had in his pocket the little mirror with which he had signalled to Ferrier on the march from the farm. Perhaps he could signal to him now--tell him of his plight, and warn him of the reinforcement of the enemy. The warning would be of little use to him, for he could not materially strengthen his defences; but it would at least show him the folly and the impossibility of attempting a rescue. Neither his guards nor the villagers would understand what he was about. He took the mirror from his pocket. The group of onlookers who had never left him came nearer: what was this piece of solid water that the msungu held?
