"An iceberg!" exclaimed the young skipper, who was the first to recognise the true nature of the obstacle. "An iceberg driven in by the gale and jammed. Now we are in a fix."

"I should say as much," responded Cabot, "for there isn't space enough to let a rowboat out, much less a schooner. No wonder this water is as still as that in a corked bottle. What shall we do now?"

"Wait until it melts, I suppose," replied White gloomily, "or until the outside seas batter it away."

So our lads had waited unhappily and impatiently for more than a month, and still the ice barrier was as immovable as ever. Also, as the weather was growing steadily cooler, its melting became less and less with each succeeding day.

During this period of enforced imprisonment they had made several exploring trips into the interior, but had failed to find trace of human life; nor were they able to go far either north or south on account of impassable waterways. Neither could they discover any timber from which to obtain firewood, and as the supply on the schooner was nearly exhausted their outlook for the future grew daily more and more gloomy.

For a while they had hoped to signal some passing vessel, and one or the other of them made daily trips to the most prominent headland of the vicinity, where he kept a lookout for hours. But this also proved fruitless, for but two vessels had been sighted, and neither of these paid any attention to their signals.

Thus the open season passed, and with the near approach of an Arctic winter the situation of our imprisoned lads grew so desperate that they were filled with the gloomiest forebodings.
