In an hour a series of shouts and cries disturbed the silent night. It was the cry of the warriors on the north side of the stream.

Harry, who was one of the watchers with Tom, called to his companion: “Did you hear that? I wonder if John is in trouble?” The sounds were repeated, and finally reechoed by those on the south side of the river. Everything seemed to be confusion, and the sound of tramping feet in the distance became plain.

The Professor was wakened, and the situation explained. “Hasn’t John returned? How long has he been away? Which direction did he take?” The questions were hurriedly asked, and when the boys stated that he had disappeared in the direction that the sounds came from, the matter took on a very much more serious aspect.

All crowded around the Professor, and one suggestion after the other was made, first as to the cause of the uproar, and then as to the condition of John.

“It is evident that the cause of the alarm comes through John, but how he has caused the difficulty, or what his motive is, I do not know. I cannot advise any of you to put yourselves in danger at this time.”

The tumult increased, and it appeared that the sounds moved near to the stream north of their position. While thus speculating Harry noticed a movement close to the clearing and near the fringe, along the stream. It was someone stealthily crawling along, and coming toward the wagon.

“Shall I fire?” asked Tom. The Professor held up a restraining hand. “Wait until we see what the object is.”

Coming nearer, a savage was plainly seen with his distinctive headdress, and he was now within thirty feet of the wagon. The boys were shocked to see John’s gun strapped on the warrior’s shoulder, as he carried a bow in one hand. A few feet farther and he stood up, and held up an outstretched hand, and uttered the words: “Keep quiet.”

It was John.

The relief almost caused a shout; but they remembered the injunction, and restrained themselves. In a moment more he was in the wagon; and the inevitable questions began.
