things, and it became not only a valuable assistant, and a wonderful scout inp. 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 servicep. 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.

John was an educated man, an archæologist, and, next to the Professor, had the most varied knowledge of any one the boys ever met, and it can be understood, that their association with men of that class made them remarkably active in seeking out and understanding the wonderful things that nature presents in every field of human activity.

In order to be as brief as possible with this part of the story, it is necessary to add that the rescue of the two boys, and the restoration of John's faculties, made a strong party, and new weapons were made, and the real expeditions through the island begun.

During the first extended trip, the Professor was captured. Out of this misadventure grew some of the most remarkable series of events, but finally, they were successful in rescuing four more of their former companions, and two of John's shipwrecked companions.

The capture of the Chief, formerly alluded to, and the subsequent rescue of a chief who was about to be offered up as a sacrifice, served as a means to bring two of the tribes to the rescue of those in the expedition, and the Professor, by his wisdom, was able to enlist the services of the tribe which had captured him.

The events which lead directly up to the beginning of this volume were brought about by the enmity of two of the most bitter and vindictive tribes, which compelled the Professor and the boys to form an expedition against those hostiles, in which four other tribes assisted.

They captured the Chief, and rescued two of their former companions, and then built a town called Unity, where the advantages of civilization were taught the natives, and to which place many of the families of the natives emigrated.

All the chiefs formed an alliance of peace, and the Professor was made the chief magistrate. After peace and order had been restored, the boys again began to long for home. Prior to this they had determined to build a ship large enough to take them to the nearest shipping point, and they were now feverishly engaged in the work with the aid of the natives, who were eager to learn how the white men built the wonderful things which they saw all about them.

It will, therefore, be understood, that the remarks of George, at the opening of this chapter, had reference to the fact that the most important of the islands, or the ones having the most of the treasures could not be the one on which they resided, but pertained to some other localities.

"Well, if there is anything I am interested in, it is to know why the wonderful buildings we found at the Illyas' village were put up at that place, and what caused all trace of them to be lost," said Harry, after George had expressed his last opinion.

"Do you remember what John said, after we came out of the cave below the village?"

"No; what was it!"

"He said the copper in the cave might explain it."

After the capture of the last tribe, John demanded that the Chief inform them of the location of thep. 24 Hoodoo, or Medicine Men of the tribe, and he reluctantly consented, but the Chief warned them, that to attempt to enter the cave would mean Death.

John knew that the Chief and the people believed the death tales told by the Medicine Men, as it was tales of this kind which enabled them to maintain such a hold on the people. In order to destroy the power of those people, who really had been the cause of much of their troubles, John announced that he would take the Chief and his followers to the cave, and that he would then go into the cave alone, and come out again, to prove that the Medicine Men had lied to him.

John entered the cave, and single-handed captured the Krishnos, as they were called, and brought them out, thus verifying his statement that those men had deceived the people. Soon thereafter John and the boys entered the cave, which, from the description he had, contained an immense amount of treasure, but they were unable to discover any trace of it if it existed.

By accident the calcareous deposit was broken off at one part in their search, and below was found a dark material, which, after examination, was found to be copper. It was not in its native state, but was a product produced by smelting the ore, and they uncovered an immense quantity of it, sufficient to show that the portion of the cave in which it was found was really a storehouse.

Not more than a mile away was the Native village, where they held the tribe captive. The village wasp. 25 absolutely unlike anything else in the form of habitations found in the island. Three of the buildings were large structures, built in three of the well-known types of architecture, and the other parts of the village were laid off regularly.

Surrounding the village was a strong
