"We have struck a polar reef!"

It was Captain Barrington who uttered these words after a brief examination.

"Do you think we will be able to get off?" Frank asked Ben Stubbs, who with the boys and the rest of the crew was in the bow peering down at what appeared to be rocks beneath the vessel's bow, except that their glitter in the lanterns that were hung over the side showed that the ship was aground on solid ice.

"Hard to say," pronounced Ben. "These polar reefs are bad things. They float along a little below the surface and many a ship that has struck them has had her bottom ripped off before you could say 'knife.'"

"Are we seriously damaged?" asked Billy, anxiously gazing at the scared faces around him.

"I hope not," said the old salt; "there is one thing in our favor and that is that we were being towed so that our bow was raised quite a bit, and instead of hitting the ice fair and square we glided up on top of it."

Another point in favor of the ship's getting off was that there had been no time to reshift the cargo, which, it will be recalled, had been stowed astern when her bow was sprung off Patagonia, so that she rode "high by the head," as sailors say. So far as they could see in the darkness about twenty feet of her bow had driven up onto the polar reef. The Brutus had stopped towing in response to the signal gun of the Southern Cross in time to prevent the towing-bitts being rooted out bodily or the cable parting.

"There is nothing to be done till daylight," pronounced Captain Barrington, after an examination of the hold had shown that the vessel was perfectly dry. "The glass indicates fair weather and we'll have to stay where we are till we get daylight."

Little sleep was had by any aboard that night, and bright and early in the morning the boys, together with most of the crew, were on deck and peering over the bow. The day was a glorious one with the temperature at two below zero. The sun sparkled and flashed on the great ice-reef on which they had grounded, and which in places raised crested heads above the greenish surface of the sea.

No water had been taken on in the night, to the great relief of the captain, and soon a string of gaudy signal flags were set which notified the Brutus, lying at anchor about a mile away, to stand by. The hawser had been cast off over night and so the Brutus was free to steam to any position her captain thought advisable. As soon as the signalling was completed he heaved anchor and stood for a point about half-a-mile to the leeward of the Southern Cross, where he came to anchor once more.
