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 gri

"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. Ki

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. Ki

"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. Ki

"How much will you need?"

"A piece eighteen inches square will be plenty," was the reply. Mr. Ki

"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. Ki

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.

The Hunter was not laughing, however, and could scarcely have felt less like it. He wanted to talk to Bob but had so much to say that he could hardly decide where to begin. He was intensely relieved when his young host took up his station in the bow of the boat rather than at an oar; and the instant Bob was looking away from his friends, the Hunter attracted his attention.
