“That’s sound, and sensible, and sportsmanlike,” said Dick, approvingly. “And besides, we really haven’t any time to spare if we’re going to stop on the island yonder for dinner, as we agreed, and—”

“And as at least one appetite aboard the Hunkydory insists that we shall,” interrupted Cal. “It’s after three o’clock now.”

“So say we all of us,” sang Tom to the familiar after-dinner tune, and Larry shifted the course so as to head for an island nearly a mile away.

There a hasty dinner was cooked and eaten, but hasty as it was, it occupied more time in preparation than had been reckoned upon, so that it was fully five o’clock when the dory was again cast off.

In the meanwhile the wind had sunk to a mere zephyr, scarcely sufficient to give the heavy boat steerage way, and, late in the day, as it was, the sun shone with a sweltering fervor that caused the boys to look forward with dread to the prospect of having to resort to the oars.

That time came quickly, and the sails, now useless in the hot, still air, were reluctantly lowered.

A stretch of water, more than half a dozen miles in width, lay before them, and the tide was strong against them. But they pluckily plied the oars and the heavy boat slowly but surely overcame the distance.

They had found no fresh water on the island, and there was very little in the water kegs when they left it for their far-away destination. The hard work of rowing against the tide in a hot atmosphere, made them all thirsty, so that long before they reached their chosen landing place, the last drop of the water was gone, with at least two more hours of rowing in prospect.

“There’s a spring where I propose to land,” said Cal, by way of reassuring his companions. “As I remember it, the water’s a bit brackish, but it is drinkable at any rate.”
