By degrees they began to make various articles, found copper, iron and various ores, as well as lime-rock and grindstone formations. With these, and the knowledge of the Professor, they finally succeeded in making iron and copper tools and implements, built a water wheel, erected a sawmill, and eventually turned out a primitive pistol or gun.
During this time, however, they were interested in discovering what the island contained. The first voyage was on foot through a forest, where they saw an exciting combat between bears for the possession of a honey tree, and witnessed the death of one of them. By the accidental discovery of the honey tree they were supplied with an excellent substitute for sugar.
In the next voyage a large river was discovered to the south, which they named the South River. The second voyage was along that stream, until they reached a falls, where they were compelled to leave the crude boat which was made before starting on this voyage, and they proceeded on foot.
After a week's adventure in the forest they found a fire plot, which was the first indication that the island was inhabited. As up to this time they had no weapons but bows and arrows, which they had made, they returned home hurriedly. On the journey they had the fortune to capture a yak and her calf, and subsequently became possessors of a small herd, two of which they trained. A wagon was built and a store of provisions gathered in. A crude machine was constructed to weave the ramie fiber, the plant of which they found growing on the banks; in addition they had success in making felt cloth from the hair of the yak.
After providing many of the things which were necessaries, and several samples of firearms, as stated, they determined to go on their third voyage of discovery. During the various trips several mysterious and inexplainable things occurred. First, the fire on the banks of the Cataract River, about fifty miles from their home. Second, the disappearance of their boat, which had been left below the falls in South River; and, third, the removal of their flag and pole at Observation Hill, a half mile from their home, during the time they were absent on the third voyage.
They were now on their fourth voyage, and the incident mentioned on the opening page of this chapter related to the first large animal they had discovered.
In a short time Harry and the Professor returned from the search. "We have lost them, but shall undoubtedly find them later on," was all he said.
The forest was still to the south of them, and to the north the sea was now distant fully three or four miles, as the coast seemed to trend to the northwest, after passing the wild barley fields. The ground appeared to be more open and level, so a more southerly course was taken in that direction. Before night they emerged from the dense forest, which still continued to the right.
No stirring incidents occurred during the day, until night was approaching, when, on entering a straggling forest of detached trees and thick underbrush, George, who was in the lead, and acting the part of the scout, rushed back and held up a warning hand. The team stopped while Harry and the Professor quickly moved toward George.
"I have seen some orang-outans; come quickly."
