"Is it impossible to free it?"

"Impossible, at present."

To attempt to repair the accident at that moment was out of the question. The screw would not move, and the steam, being no longer effective, had escaped through the valves. The captain was, therefore, forced to rely on his sails, and seek the aid of the wind, which had been hitherto his most dangerous enemy.

He came on deck, and, briefly informing Glenarvan of the situation, begged him to return to the cabin with the others; but the latter wished to remain.

"No, my lord," replied Captain Mangles, in a firm tone: "I must be alone here with my crew. Go! The ship may be in danger, and the waves would drench you unmercifully."

"But we may be of use——"

"Go, go, my lord; you must! There are times when I am master on board. Retire, as I wish!"

THE STRUGGLE CONTINUED.

For John Mangles to express himself so authoritatively, the situation must have been critical. Glenarvan understood that it was his duty to obey. He therefore left the deck, followed by his three companions, and joined the ladies in the cabin, who were anxiously awaiting the result of this struggle with the elements.

"My brave John is an energetic man," remarked Glenarvan as he entered.
