It should not be forgotten to mention Red Angel. Over eight months before a baby orang-outan had been captured. He had grown rapidly, and George, the elder of the two boys, had taken a special delight in teaching or training him, and the result was that the imitative quality of the animal made him useful to the party in many ways. Angel was with them also, and was the only amusing element in their days of stress and tension.

The condition before them at this time was one of intense interest. For the first time since their arrival, savages had been seen. From the first view it was apparent that the party sighted were on the point of meeting a hostile tribe, and while it was their intention to journey west to the large stream called by them West River, it was concluded to remain at the present camping place until they could more fully observe the attitude of the natives.

During two days previous the route had been through a dense forest, and they emerged from this only a few hours before, their object being to make their way to the river, as in the vicinity of the stream there was not much wood, and the land was covered with comparatively little underbrush. They felt that with the strongly built wagon, which had been purposely made with a large, thick body, it would be more serviceable to them as a means of defense than the woods, because the forest would serve as places of concealment for their enemies, while adding nothing to their security.

The strange man, who, in the absence of his true name, was called John, noting the different ones climbing to the wagon top, also made his way there, and gazed in the direction pointed out by Harry. He glanced toward the savages, and then looked wonderingly at the boys and the Professor. He did not appear at all disturbed, nor did he venture to indicate by any sign that he understood or comprehended any danger.

And Angel, too, took a hand in the sights. He was beside George, and the latter pointed out the savages, but if he knew what George meant his face and actions did not show it. How little we know of the workings of the human mind, and how should we know more of what passed in the mind of that animal as he listlessly viewed the scene which so much interested the others? We shall see, later on, how Angel profited by the lesson which they tried to teach him.

"They seem to be fighting; at any rate, I can see them going toward each other, and others running wildly about."

"Our better plan would be," said the Professor, "to go up nearer. In that way we may be able to take advantage of their quarrel."

This seemed to appeal to the boys, and they were down instantly. The yaks had been unyoked, prior to this, but they were now hitched up in a hurried manner, and the wagon moved forward.

A word now as to the equipment of the wagon. It had been made with unusually high sides, and was of thick boards, so that they did not fear the arrows which, undoubtedly, were the only form of missiles which would be hurled against them. Within were ten guns, each with a barrel twenty inches long, and a three-eighths of an inch bore. All were muzzle-loaders, as they had no facilities for making breech-loaders, so that it would be impossible to fire rapidly, after the first ten shots; but they counted on being able to hold out against a pretty strong force of savages, armed as they were.

The wagon went forward slowly, and was kept as much as possible within the sheltering range of the underbrush. All were in the vehicle, as its height gave them a better view, and in case of a surprise all would be guarded and safe.
