CHAPTER VI

DISCOVERY OF THE ISLAND AND EXPLORATIONS

Weary, they dragged themselves over the cliffs and down to the waiting

natives. Muro was surprised to learn that they had found no signs of

people, so they rowed back to the ship, and after a hearty meal, retired

for the night.

In the morning when they asked John for his opinion, he said, "The only

course is to sail south, and circumnavigate the island. In doing so we

shall effect a landing every ten miles or so, and then go into the

interior. This will thus enable us to learn all about the land. At the

same time we must survey the island, so as to learn its extent, as well

as its general shape and outline."

"But how can we survey it without the instruments?"

"That is readily done, by observing the headlands, or some special coast

line marks, and then taking the angles from those points."

"Well, that will be interesting, at least. How shall we start?"

"Do you see that point to the south which may be five or ten miles

away?"

"Yes."

"Now, examine the compass, and turn it so that the cardinal points are

directly north and south. Now sight across the face of the compass so

that you get the exact line between this point and yonder object. What

do you make it to be?"

"Why I make it out to be S. E."

[Illustration: _Fig. 5. Measuring by Triangulation._]

"That is correct. The line 1 is south by east."

"But how can we find out how long line 1 is?" asked Harry.

"Why by triangulation," said George, quickly.

"I know that, but how can we do it on sea?"

"It can be done on sea, as well as on land, but we had better go and

make the first measurement by triangulation correctly, and do this in

our subsequent measurements, unless it should be necessary to make the

measurements at sea. The plan followed on shipboard will be found

similar to the plan followed on land."

The boat was manned and the boys with a crew of the men and John made

for the shore, and together they went inland to a point marked B (Fig.

5), and sighted across to the same object C that was noted of the ship.

This, then, gave three lines, 1, 2 and 3, forming a triangle.

"If these angles are placed on a paper the distance from A to C can be

determined on the principles of proportion," remarked John.

"How is that done?"

"We will assume that the lines 1, 2, are at right angles to each other.

This is not necessary, but it happens to be so in this case. Let us

first measure the distance along the line 2, which may be any number of

inches, or feet. Suppose we call the line one inch long. Then draw the

line 1, so that it will be sufficiently long to be sure and meet the

line 3."

"Yes; I now see how it is done," remarked George, with enthusiasm. "If

the line 3 is drawn at the angle we got, when we looked at C, from B,

the line will cross line 1 at C."

"That is correct. Now, if it is one inch from A to B, we may use that

inch as a measurement to get the distance along the line."

"Let me step it off," said Harry. "I find it is just two and

three-quarters inches."

"What was the distance, in feet from A to B?" asked John.

"I have the figures here," said George. "We found it was six hundred and

ninety feet."

"If, now, you will multiply 690 by 2-3/4, we shall have the distance

from this point A, and yonder point, or headland C."

[Illustration: _Fig. 6. The Second Limb._]

"I make it out to be just 1897.5," was Harry's conclusion.

The boys, together with John and a half dozen of the natives, went along

the shore, and mounted the point C, and from that place selected another

point in a southerly direction, and again made the same calculations.

The vessel in the meantime was put under sail and anchored a mile

below, giving the surveying party time to make several triangulations,

and late in the afternoon the party came on board, tired and ready to

take a rest.

From the position taken up by the ship they could see a long stretch of

shore line, practically straight, trending toward the southeast, and

with their glass could see, miles away, a headland which afforded a

pronounced point for observation.

The next morning the same parties rowed to the shore, and Uraso was left

with the party to guard the shore boat, while Muro accompanied John and

the boys. On this occasion John issued the following instruction:

"The long point which you see in the distance is, probably, 15 miles

beyond. It is not more than that, but this clear atmosphere is liable to

deceive. I have instructed Sutoto to wait until one o'clock today, and

if by that time there is no word from us Uraso will return to the ship,

and you will take up anchor and steer for the headland beyond."

"So that you may understand our movements, we will strike into the

interior, taking a course due east, for ten miles, or thereabout, and

then turn to the south, and reach the sea near the place where the

vessel will be located."

"I understand, now, how the distance can be measured by triangulation on

land; but how to get the distances, on shipboard, is what puzzles me,"

said Harry.

John smiled as he replied: "I knew you would come to that sooner or

later, so I prepared a little sketch (Fig. 7), which shows the bow of a

vessel, and the tall mast. The lines from A to B give an angle with the

vertical line of the mast, which will enable you to determine how far

the ship is from any point."

"But I am still in the dark as to how, even if we have that distance, we

can thereby tell by triangulation, on the vessel, how far one point is

from another on the land."

[Illustration: _Fig. 7. Triangulation from a Vessel._]

"After the distance from the vessel to the point is determined, as I

have shown, then the length of the ship itself is used as the two points

to sight from, and the two lines thus projected, from the opposite ends

of the vessel, together with the line lengthwise along the ship, form a

triangle, the same as the triangle lines 1, 2, 3, in the sketch (Fig.

5)."

It might be well at this place to describe the equipment of the party as

it left the boat. The natives carried a plentiful supply of provisions.

Each had a gun, the best kind of breech loaders, and also a spear.

The natives love to handle spears better than anything else in the way

of a weapon, and each also had a knife, and some carried the inevitable

bolo, that primitive form of hatchet which is known all over the world

where steel or iron is available, and the people have arrived at such a

state that they are able to make metal articles.

John and the boys also carried guns, but the boys had revolvers, seven

shooters, not of large bore, but very convenient weapons, in close

quarters. Each carried also a knife, and belt to contain the cartridges

for the guns.

Harry carried a camera, which he had brought from the States, and George

had the field glass strapped across the shoulders. John felt that they

had a force large enough to make a fairly effective stand against a

pretty strong force of natives, the entire party counting, in this

instance, sixteen.

As they advanced into the interior, it was evident that they were

gradually ascending, so that at about six miles from the landing place

they reached the crest of the rising ground. Beyond, where the nature of

the ground permitted they saw clearly that the distance beyond had a

lower altitude than the place where they stood.

During this trip there was no evidence that the island was occupied, but

they saw the most amazing evidences of tropical fruits and trees.

Magnificent trees were in evidence everywhere, and the woods, besides

mahogany, and ebony, were of the most valuable character.

John noted all these things, but the boys were most interested in the

birds and animals which roamed about. The latter were not large or

vicious looking, but it was not permitted to shoot any of them lest it

might alarm Uraso, who was at the landing.

Ahead could be seen several ridges, one of them heavily wooded. Reaching

the summit they beheld a beautiful valley below, and opposite on a

shelving rock, stood a type of mountain deer like a sentinel, while a

dozen or more were feeding on the green slope beneath.

Frequently on the march the boys would take side trips, in the attempt

to run down some of the curious animals, but they were careful to keep

the main force in sight.

Thus they tramped on fully five miles beyond the crest of the ridge, and

occasionally John would stop to examine some suspicious-looking

indication of habitation.

"It would surprise me very much to find that the island is not

inhabited," he said, as he examined what appeared to be a path.

At this juncture one of the native scouts came up and showed John a

curious stone formation. John took it, and turned it over several times.

"That is part of a stone hatchet." The scout nodded assent with a

smile.

All now became intent on searching. This finally resulted in bringing to

light a well-formed spear, not unlike those originally used on Wonder

Island among the native tribes.

Surely they were getting evidence pretty fast now. Then, while crossing

a little rivulet, one of the scouts plainly saw the print of a native

foot, which was unmistakable. True, it had been made days before,

probably a month, but there it was, and now it was incumbent on them to

find out where the people were.

The entire party scattered along the little stream, and searched both

banks for a considerable distance, the boys taking an active part in the

work. Usually the boys kept together, and entertained each other, but on

this occasion all were so intent on discovering where, and in what

direction the footprints would lead, that they quite forgot to watch

each other.

John gave a customary whistle, as he was in the habit of doing, when it

was desired to call the party together, and all of the scouts promptly

returned, as well as Harry. George was nowhere to be seen. John

questioned Harry. He had first missed him at the bend in the stream not

two hundred feet to the north.

He rushed back in that direction, while John gave another blast on the

whistle, and then listened intently for a reply. Harry came back without

any intelligence, and almost frantic. John and the scouts then broke

into a run, and Harry turned with them.

That instant a shot rang out. "That must be George," exclaimed John.

"Forward as quickly as possible."

The party turned the bend of the river. All along this part of the

stream the banks were cut up by ridges and diminutive cliffs, and in

many places were large shelving rocks which came up close to the stream.

Immediately after the shot John stopped, and listened for some sound,

and the natives, usually so alert to recognize noises, did likewise.

"That shot means that George is in some danger," said John.

"But why does he not answer the whistle? Why should he shoot, and then

not call to us, if there is any danger," said Harry in despair.

They turned the bend, and searched to and fro. The shot could not have

been more than eight hundred feet away. The searchers spread out into a

fan-shaped formation. One of the scouts ran up hurriedly and called to

John, who went forward, and there, alongside of a huge rock, where there

was little grass, he saw unmistakable evidence of a scuffle.

"These are the footprints of George's shoes," remarked Harry.

"Yes, and here are the prints of the native feet," said John, as one of

the scouts distinctly pointed out two or three well defined marks.

"They are, undoubtedly, near at hand. We must now be on our guard," said

John, as he pondered on the situation.

"I wonder why they didn't attack us?" asked Harry.

"The reason, no doubt, is that it is a small party. A larger body would

not have attempted to capture one of us by stealth."

John turned to Hasmo, one of the fleetest runners, and instructed him to

go back to the landing place at once, and advise Uraso to bring his men

and provisions, as well as additional ammunition, and to hold the ship

until additional word should be sent.

Hasmo was off in an instant, and then John issued additional

instructions. "It is evident," he said, "that we must look for the

people to the east or, more likely, toward the southeast. That is the

reason why I had the boat held at the place where we have just landed.

There is also another reason why I think the tribes, if there are any,

are to the south, and that is, in this latitude they are much less

exposed to the effects of the great winds that occur at certain portions

of the year."

Harry wandered about, not knowing what to do, at this terrible

catastrophe. George in the hands of the savages! He could hardly believe

it.

"Don't worry about George too much," said John consolingly. "I am

inclined to think he has had enough experience within the past two years

to help him out of immediate trouble, and we will then be able to take a

hand."

This somewhat relieved Harry. It is possible that George might be able

to take care of himself. "But suppose they kill him?" This was his great

fear.

"It is not at all likely they will do that," remarked Muro. "Those who

captured him form only a small party, and it is not at all likely that

there was a chief with them. Under the circumstances they would not dare

kill him until the Chief ordered it."

John smiled as he nodded at the explanation given by Muro. After all, it

was not as bad as it might be. Now to the rescue. Muro begged permission

to do scouting work until Uraso arrived, and selecting Stut as his

companion, they glided through the forest directly to the east.

They were now fully twelve miles from the boat, and the runner could be

depended on to reach Uraso within an hour, if not hindered on the

journey. It would then take, possibly, two hours more for the party to

return, so that it was safe to assume that they would have to remain in

the vicinity for the next three hours.

John decided that the time should be spent in exploring the directions

to the southeast and to the northeast as well, so they might be well

informed when the reinforcements arrived.

Hasmo glided through the forest like a deer. He knew that it was

imperative to reach the shore before one o'clock, because at that time

the vessel would leave for the southeastern point. To get there too late

would mean a trip for fifteen miles or more along the shore to reach the

next landing.

The dense forest near the shore prevented him from seeing the vessel

until he crossed the last ridge, and when he finally came within view

of the harbor the ship had disappeared. He stopped and glanced to the

south, but no ship was in sight. This was a situation which had been

considered, from the point of view of the departure of the vessel; but

where had it gone?

He went to the shore, where Uraso's party had been, and then,

laboriously ascended the point beyond, and from which he could get a

clear view of the sea. There, far beyond, was the _Pioneer_, sailing to

the southeast under a strong breeze.

He tore off his jacket, and seizing a branch, began to wave it back and

forth. The ship went on, and there was no indication that they noticed

him. He remained thus for nearly a quarter of an hour, and then knew

that he must follow the ship until he reached the next landing place.

The trip along the shore was a most difficult one, as he could not

follow the beach. Many of the rocks along the shore were licked by the

waves, so that he had to take a course beyond the cliffs, and the land

was not only rough, but numerous gulleys, or draws, as they are called,

were washed out, making speed impossible.

It required more than two hours to make the trip, and it was

considerably after three when he hailed the boat from the shore, and

hurriedly told the story of George's capture.

Uraso was not slow in gathering the men needed for the expedition, and

when the guns and ammunition were brought out all of the men actually

begged to go along, but he knew that John would not sanction leaving the

vessel without a crew.

* * * * *

John and his scouts impatiently awaited the return of the men and during

this time received the reports from the scouts as they came in. It was

evident from the slight traces found that the band which captured George

had gone east. It was no doubt from some indication to this effect

obtained by Muro, that induced him to take his course in that direction,

also.

All had departed but Muro: Four o'clock came, and then five, but neither

Muro nor Uraso appeared. This did, indeed, look strange to John, who

could, in a measure, account for Muro's non-appearance; but he could not

understand why Uraso did not come. It then occurred that after all Hasmo

might not have been able to reach the landing before sailing time, and

with this theory he consoled Harry, who was constantly on the alert,

waiting for tidings.
