It was in these larger openings that the boys did most of their searching-it would have been impossible to get anything out of the others, reckless as some of the youngsters tended to be.
Rice, the first one out of the boat, had run to one of the largest while the others were still pulling the little craft up and making it fast; and dropping into a prone position with his head over the edge, he shaded his eyes and looked down into the clear water. By the tune the others came up he was already pulling off his shirt.
"My chance first," he said quickly as the others peered down to see what he had sighted. Before anyone was sure what he was looking at, Rice had slipped into the water, disturbing the surface so that nothing was clearly visible. He stayed down for some time, and finally reappeared asking for one of the poles that were carried in the boat. "I can't work it loose," he said. "It seems to be jammed in place."
"What is it?" several voices asked at once.
"I'm not sure; I've never seen anything like it. That's why I want to get it up." He received the pole which Colby handed down to him and slid under water once more. The object at which he was prying was about five feet below the surface-that is, it varied from about four to six feet as the water level rose and fell in response to the urge of the breakers.
Several times Kenneth came up for breath, without having dislodged the mysterious object; and finally Bob went down to help. He had one advantage over the other boy, thanks to the Hunter's prompt supplementing of the curvature of his eye lenses with some of his alien body material Bob could see much better under water than usual. He could make out easily the shape of the object on which Kenneth was working but did not recognize it. It was a hollow hemisphere of dull metal eight or nine inches in diameter and half an inch thick, with the flat side protected over half its area by a plate of similar material. It was hung on a stubby branch of coral only a few inches from the bottom, rather like a cap on a peg; and another lump of the stuff had either fallen or grown so as to wedge it in place. Rice was prying at the upper lump with a pole.
After a few minutes of futile effort they stopped, got their breath, and planned a more co-operative method of attack. Bob, it was agreed, would go to the bottom and work the end of the pole behind the object; Kenneth, upon receiving his signal, would brace one foot against the steep side of the pool-they both wore their shoes, as any sane person would in a coral pool-and push outward, to get the thing out from under the heavy fragment that pinned it down. The first time the attempt failed; Bob did not have the pole well enough set and it slipped out. The second, however, succeeded-almost too well. The piece of metal popped free and rolled away from the wall into deeper water; Bob, who was approaching the end of his store of breath, came to the surface. He refilled his lungs and started to speak to Rice, and then realized that the redhead was not visible. For a moment he supposed the other boy had taken a quick breath and gone back down for his prize, but as the water sank abruptly Rice's head appeared.
"Help! My foot-" The words were cut off again as the water surged up, but the situation was crystal-clear. Bob immediately dived again, braced his feet on the bottom, and strove to lift the lump of coral, which had been freed by the removal of the piece of metal and had landed on Kenneth's foot He was no more successful than before, and returned anxiously to the surface just as the water went down again.
"Don't talk! Get air!" Malmstrom yelled superfluously -Rice was too busy to do anything else when the opportunity to gulp air occurred. Bob was looking around for the pole, which had disappeared. He saw it floating a few yards away and went after it. Colby had disappeared toward the boat without saying anything; as Bob came back with the pole and prepared to dive once more, the young boy came back. He was carrying the bucket that Hay had brought from the pool.
Everything had happened so rapidly that Malmstrom and Hay had scarcely realized what was going on. They now looked at Hugh Colby and his bucket in astonishment. Colby wasted no time explaining. He threw himself face downward at the water's edge and reached out and downward to the trapped Rice. As the water receded he placed the inverted bucket over the other's head and spoke his only words during the entire incident.
"Hold it there!"
Rice, for a wonder, got the point, and followed orders; and as the water surged up again over his head he found his face enclosed in a bucket full of air. Bob had not seen this trick, as he was under water again prying at the lump of coral but he came up a moment later, saw, blinked in bewilderment, and then understood.
"Shall we come in?" Hay asked anxiously.
"I think I can get it off this time," Bob replied. "I was worried at first because of his air supply, but hell be all right now. Just a minute till I get my own breath." He rested a moment, while Hay yelled encouragement to his trapped comrade in the intervals that the latter's head was above water. Robert found time to mutter to the Hunter, "This is why I didn't want to come here alone!" Then he took a firmer grip on the pole, and submerged again.
This time he succeeded in finding a better point of leverage, and applied all his strength. The lump of coral started to shift, and he felt that the work was about done, when the pole broke, the splintered end raking down his own chest. For once the Hunter could raise no objection; the injury was clearly "line of duty," and he closed the scratches without resentment Bob popped back to the surface.
"I guess you'd better come inat that. I got it started, and the pole broke. Get the other poles, or maybe an oar or two and everyone who can get at it come in."
"Maybe we'd better go for a crowbar," suggested Malmstrom.
"Maybe we'd better do the work ourselves," retorted Bob. "The tide's coming in, and that bucket will be good just so long as the water gets below his head every few seconds. Come on."
Within a few seconds the four boys, armed with poles and oars, were in the water beside their comrade: Bob at the bottom placing the levers, the others supporting them and ready to lift when he gave the word. They knew nothing about his advantage in seeing under water, of course; they accepted his leadership simply because he had started telling them what to do and no one intended to argue at a time like that.
Heavy as the block was, it yielded to this concentration of effort, though the job nearly cost them an oar. For just a moment the fragment of coral lifted, and Kenneth was able to drag his numbed foot from beneath it With the aid of his friends he scrambled out of the water and sat nursing the foot while the others gathered around.
Rice was remarkably pale, considering his normal tan, and it was some time before his breathing and heartbeat returned to normal and he felt like standing up. The other boys were almost as frightened, and for some time nobody suggested going back into the water for the piece of metal that had started the trouble. After ten minutes or so Rice suggested that it would be a pity if all that work were wasted, and Bob took the hint and went down again; but the thing was not visible among the sea fans and branching corals that covered the pool's bottom, and he stopped groping under things after encountering a sea urchin which believed in passive resistance. Rice had nothing to show for his afternoon's work but fright, which was not the sort of souvenir he had any intention of showing to his parents.
It was now almost half-past four, which left plenty of tune before supper, but somehow the prospect of further search on the reef no longer attracted them. They decided, with very little argument to row the two miles and a fraction that separated them from the big dock. "That ought to be fairly peaceful, with the ship not due for nearly a week," Hay innocently remarked. No one said anything in answer at the time, as all of them probably had some such idea in mind; but he heard a good deal about that remark later.
The Hunter hardly heard the statement, of course; for the past quarter hour his mind had been fully occupied with a generator casing he had just seen and felt and which had definitely not come from the flattened wreckage of his own ship.
Chapter XII. AND FALL!
THERE WAS little talk for the first half of the row, for th
ey had been badly scared; but when Norman Hay passed a remark about his aquarium the conversation quickly blossomed full strength.
"Maybe we can find something here to get one of those cement plugs out of the pool," were his words.
"You'll need something pretty good," remarked Shorty. "That underwater cement you got is rugged stuff-at least they used it on the dock, and there's no mark yet where the tanker comes in."
"The tanker doesn't touch the dock, unless someone gets careless," pointed out Rice from the bow. "Still, Norm's right about needing some good tools. There's nothing around our house that'll do, I know."
"What'll we use, anyway-hammer and cold chisel!"
"You can't get much good out of a hammer under water. We need a long, heavy crowbar with a good point. Who knows where we can get one?" There was no answer to that, and Hay continued after a moment. "Well, we'll ask some of the dock crew, and if they don't know, the construction gang up on the hill is bound to."
"If we could snaffle a diving helmet we'd get the work done faster," Rice contributed.
"The only helmets on the bland are the rescue rigs on the dock and at the tanks, and I don't think they'd appreciate our borrowing one of those," Bob said. "We could never get the suit, and anyway probably Shorty's the only one who could wear it."
"What's wrong with that?" Malmstrom wanted to know.
"You'd be kicking about doing all the work. Anyway, they wouldn't let us take it"
"Why don't we make one? There's not much to it."
"Maybe not; but we've talked about that for four or five years and wound up holding our breath every time we worked under water." It was one of Colby's rare contributions to the exchange; as usual, no one could think of an answer.
Rice broke the short silence with another question. "What are you going to use to keep your fish in? Bob said something about wire netting, but where are you going to get any?"
"I don't know that either. If there's any on the island, it ought to be in one of the storerooms on the dock. I'll try to scrounge a piece if there is, and we'll get some heavy wire and make it if there isn't. The hole won't be very big anyway."
They tied up at the foot of a ladder on the landward side of the structure, almost under the causeway leading from the shore; Rice and Bob made both bow and stern painters fast while the others went up to the main level without waiting. Ken had a little trouble with the ladder because of his foot, but managed to conceal it fairly well. Once on the dock, the group looked around, planning.
The dock was a large structure, even as such things go. The weekly production of oil was considerable, and expansion was still going on; storage space had been designed accordingly. Four enormous cylindrical tanks were the most striking features; their auxiliary pumping and control mechanisms looked tiny by comparison. There were no fire walls; the structure was built of steel and concrete, with numerous large drains opening on the water below, and the fire-fighting apparatus consisted principally of high-pressure hoses to wash burning oil into the lagoon.
Between and around the tanks were a number of corrugated-iron sheds similar in structure and function to the storage buildings on shore; and at the end opposite the causeway was a complicated and versatile apparatus which could be used to distill gasoline, heating, or lubricating oils from the crude products of the culture tanks-it was cheaper to make the small quantities of these which were used on the island on the spot rather than to ship the crudes for refining to Tahiti and then bring them back again and store them.
It was the storage buildings which interested the boys at the moment. None of them could think offhand of any normal use for wire netting on the island, but one never could be sure, and they intended to leave no stone unturned. They headed in single file down the narrow space between the tanks.
There was a slight interruption before they reached the storeroom they sought; as they passed the corner of one of the small sheds an arm reached out, attached itself to Rice's collar, and pulled him inside the building. The boys stopped in astonishment for a moment, then grinned understanding at one another as the voice of Charlie Teroa reached their ears. He was saying something about "stowaways" and "jobs," and seemed quite emphatic; and for once a conversation lasting several minutes took place in Rice's neighborhood without his voice being audible. Bob had wondered whether he ought to give him a hint about Teroa's intentions but had been pretty sure no damage would be done-the older boy was too pleased with himself. Nevertheless, it was a very sheepish-looking redhead who rejoined the group. Teroa was behind him, with a faint grin on his face; he winked as he caught Bob's eye.
"You kids aren't supposed to be out here, are you?" he asked.
"As much as you," retorted Hay, who had no intention of leaving while there was a chance of getting what he wanted. "You don't work here, either."
"You can ask about that," returned Teroa severely. "At least I'm helping. I suppose you're after something." It was a statement, but there was a faint suggestion of question at the end.
"Nothing that anyone will miss," replied Hay defensively. He was going to enlarge upon this theme when a new voice cut in.
"Just how sure can we be of that?" The boys whirled to see the speaker, and discovered Bob's father standing behind them. "We're always glad to lend things," he went on, "as long as we know where they're going. What were you needing this trip?"
Hay explained without reluctance-his conscience was clear, as he had every intention of asking for the wire, though he had hoped to exercise a little selection of his own in deciding whom to ask.
Mr. Kinnaird nodded in understanding. "You'll probably have to go up to the new tank car for a crowbar or anything like it," he said. "I think we can do something about your grating, though. Let's look."
Everybody, including Teroa, trailed him across the somewhat slippery steel plates. As they went, Hay explained what had happened to his pool and the way in which they had discovered the cause of the trouble. Mr. Kinnaird was a good listener, but he shot a glance at his son, which that young man fortunately missed, when he heard about the question of entering the possibly disease-laden water. The conversation reminded Bob of the book he wanted, and he asked Hay about it when the latter stopped talking for a moment. Mr. Kinnaird could not restrain a comment.
"My word, are you going to be a doctor now? You don't seem to have been acting like one!"
"No-it's just something I wanted to find out," Bob said lamely (the Hunter's troubles were coming thick and fast; he wondered when he would get a chance to talk to his host-the present background was impossible).
Mr. Kinnaird smiled and turned to the door of one of the sheds they had reached. "There may be something in here, Norman," he said, and unlocked the door. It was dark inside, but a switch in the doorframe lighted a single bulb in the center of the ceiling. All eyes focused on the same thing immediately-a large roll of quarter-inch mesh galvanized wire that might have been made to order for Norman's needs. Hay made a rush for it, while Bob's father stood back looking as though he had invented the stuff.
"How much will you need?"
"A piece eighteen inches square will be plenty," was the reply. Mr. Kinnaird took a pair of cutters from a bench at one side of the shed and went to work on the roll. It was awkward driving the cutters too far, but he handed Norman the desired piece after a few seconds' work and they went outside together.
"I didn't know that stuff was used anywhere on the island," Bob remarked as his father relocked the door behind them.
"Really?" asked the latter. "I thought you'd poked around here enough to rebuild the place if you had to." He led the way to the nearest of the storage tanks and indicated one of the safety drains beside it. "There," he said, pointing down the four-foot-square unguarded opening. The boys crowded around and looked down. A couple of feet below the opening, between them and the water a dozen feet farther down, was a protective net of the mesh that Norman was carrying.
"I shouldn't think that would be strong enough to hold a person
who fell down there," remarked Bob.
"People aren't supposed to fall down there," retorted his father. "Or, if they do, they're expected to be able to swim. That's to catch tools, which do skitter around on these plates a good deal. People aren't allowed anywhere near these openings." He turned away from the drain as the boys drew back thoughtfully, and promptly demonstrated the truth of his own words.
He slipped; at least Malmstrom insisted that it was Mr. Kinnaird who slipped first, but no one was really sure. The group acted like a well-struck set of pins in a bowling alley; the only one to keep his feet was Teroa, and he was forced to move with remarkable speed to do so. Malmstrom was knocked against Hay, whose feet went out from under him and caught the ankles of Bob and Colby. Their shoes, in turn, failed to grip on the somewhat oily metal, and Bob gave a yell as he realized he was about to put the strength of the netting to practical test.
His reaction speed had earned him his position on the school hockey team, and that was what saved him now. He fell feet first; and his toes touched the mesh, he spread his arms wide and forward, reaching as far onto the solid part of the dock as he could. The edge of the plating caught his painfully across the ribs, but enough of his weight came on his arms so that the mesh was not overloaded, and it held.
His father, on hands and knees, made a lunge for Bob's hand, but he slipped again and missed his aim. It was Malmstrom and Colby, who had both fallen within reach, who seized his wrists without attempting to rise from their prone positions and gave bun enough anchorage to let him work himself back onto solid footing.
Bob wiped sweat from his forehead, and his father appeared to brush something from his eyes as they looked at each other; then the man gave a rather forced smile. "You see what I mean," he said. Then, recovering himself a little, "I think one of us is going to be late for supper. I take it that that boat I saw tied up is yours and has to go back to the creek." The boys admitted that this was the case. "All right, you'd better charge along before something else happens. I'll be going home myself shortly, Bob. Had we better tell your mother? I thought not." There was no pause between question and answer, and they parted almost laughing.
