CHAPTER X

"TO-MORROW IS THE DAY!"

And then it was that Jerry saw that the temporary clearing of the mystery only made things darker than ever. For, why should Tod be rescued in this weird fashion? Why had the man refused to let Tod's friends come on the island? And why, why had Mr. Fulton laughed at Jerry's story—and yet followed his clue in this stealthy way? Jerry, up to his nose in the water, and deeper than that in perplexity, saw that the whole affair was really no longer the mystery of Tod Fulton's disappearance, but the mystery of Lost Island.

So, although he now felt safe from bodily harm, because of Mr. Fulton's presence, he made no sign, but waited there a scant dozen feet beyond the stern of the boat. He heard Tod answer a few low-toned questions of his father, but could not make out either question or answer. He saw Mr. Fulton pick up the oars and poise them for a sweep, dropping the blades into the water to exchange a last sentence with the shadow who stood waiting on the bank.

"Everything all right, then, Billings!"

"Varnish on the left plane cracked pretty badly, Mr. Fulton. I had to scrape it off and refinish it. It really ought to have another day to dry."

Jerry repeated, puzzled, to himself: "Left plane—what in thunder's that?"

Billings went on:

"You won't forget to bring the timer. Elizabeth will get it at the usual place if you can leave it by noon."

"It'll be there, Billings."
