Their adventures were not wholly devoid of the amusing things of life. In one of the expeditions they captured a young Orang-outang. This was carefully taught to do many things, and it became not only a valuable assistant, and a wonderful scout in[p. 20] their wanderings, but it afforded them immense amusement, which was appreciated by the boys.
And now, having been provided with suitable weapons, they determined to go on voyages of discovery, being prompted in this course, because they found in the wreckage along one of the rivers, and far in the interior, a life boat which was a companion to their own which had been lost when they were stranded in the great tempest.
It was evident to them that some of their companions were on the island, and probably, captives. This made the quest a most exciting one, so every energy was bent toward the end of helping the unfortunates.
On the initial expedition, after the completion of the first weapons, they came into contact with several tribes of savages, one of whom was captured, after being wounded. It developed that he was a chief of one of the tribes which at that time were at war with each other.
Returning from this trip they discovered at their home a distinguished looking white man in rags, totally devoid of intellect, and unable to speak. It was evident that he had met with some accident, but he was entirely harmless, and obediently took up and performed every sort of manual labor,—in fact, was an expert in any sort of mechanical operation required of him.
In hunting, or in scouting, he was a perfect specimen of the hunter, or the soldier. It seemed to be an instinct with him to render every kind of service[p. 21] that might be needed, with the gun, or the tools which were all about him. In the absence of a better name they christened him John.
On the second trip into the unknown portions of the island they met three of the savage tribes, with whom they had several battles, and one of the natives was wounded and captured. While wandering through the forests, in their efforts to return to their home, they ran into a savage village, where they were successful in rescuing two boys who had been shipmates on the Investigator which went down months before.
While this was a source of joy it was clouded by the information that they were not the ones who came to the island in the life boat that the boys had found in the river. This was evidence that others must still be in the island, and probably held as captives.
Some months after the silent John came to them, his reason and the ability to speak returned to him, and he told a wonderful tale of his wanderings, and that which impressed the boys most was the information that he had shipped in a vessel which was designed to search out the treasures hidden in the islands of the South seas.
From hints which he dropped from time to time, the islands containing the treasure were charted, and later on, one of the caves so charted was found on the island they now occupied, although they also found several which were not alluded to and could not be recognized by the description, according to the story told by John.
