Sometimes she would get in advance of the waves which carried her along, and cutting through them with her sharp prow, bury herself in their depths. At others, she would keep pace with them, and make such enormous leaps that there was imminent danger of her being pitched over on her side, and then again, every now and then the storm-driven sea would out-distance the yacht, and the angry billows would sweep over the deck from stem to stern with tremendous violence.
In this alarming situation and amid dreadful alternations of hope and despair, the 12th of December passed away, and the ensuing night, John Mangles never left his post, not even to take food. Though his impassive face betrayed no symptoms of fear, he was tortured with anxiety, and his steady gaze was fixed on the north, as if trying to pierce through the thick mists that enshrouded it.
There was, indeed, great cause for fear. The DUNCAN was out of her course, and rushing toward the Australian coast with a speed which nothing could lessen. To John Mangles it seemed as if a thunderbolt were driving them along. Every instant he expected the yacht would dash against some rock, for he reckoned the coast could not be more than twelve miles off, and better far be in mid ocean exposed to all its fury than too near land.
John Mangles went to find Glenarvan, and had a private talk with him about their situation, telling him frankly the true state of affairs, stating the case with all the coolness of a sailor prepared for anything and everything and he wound up by saying he might, perhaps, be obliged to cast the yacht on shore.
"To save the lives of those on board, my Lord," he added.
"Do it then, John," replied Lord Glenarvan.
"And Lady Helena, Miss Grant?"
"I will tell them at the last moment when all hope of keeping out at sea is over. You will let me know?"
"I will, my Lord."
Glenarvan rejoined his companions, who felt they were in imminent danger, though no word was spoken on the subject. Both ladies displayed great courage, fully equal to any of the party. Paganel descanted in the most inopportune manner about the direction of atmospheric currents, making interesting comparisons, between tornadoes, cyclones, and rectilinear tempests. The Major calmly awaited the end with the fatalism of a Mussulman.
About eleven o'clock, the hurricane appeared to decrease slightly. The damp mist began to clear away, and a sudden gleam of light revealed a low-lying shore about six miles distant. They were driving right down on it. Enormous breakers fifty feet high were dashing over it, and the fact of their height showed John there must be solid ground before they could make such a rebound.
"Those are sand-banks," he said to Austin.
"I think they are," replied the mate.
"We are in God's hands," said John. "If we cannot find any opening for the yacht, and if she doesn't find the way in herself, we are lost."
"The tide is high at present, it is just possible we may ride over those sand-banks."
"But just see those breakers. What ship could stand them. Let us invoke divine aid, Austin!"
Meanwhile the DUNCAN was speeding on at a frightful rate. Soon she was within two miles of the sand-banks, which were still veiled from time to time in thick mist. But John fancied he could see beyond the breakers a quiet basin, where the DUNCAN would be in comparative safety. But how could she reach it?
All the passengers were summoned on deck, for now that the hour of shipwreck was at hand, the captain did not wish anyone to be shut up in his cabin.
"John!" said Glenarvan in a low voice to the captain, "I will try to save my wife or perish with her. I put Miss Grant in your charge."
"Yes, my Lord," replied John Mangles, raising Glenarvan's hand to his moistened eyes.
The yacht was only a few cables' lengths from the sandbanks. The tide was high, and no doubt there was abundance of water to float the ship over the dangerous bar; but these terrific breakers alternately lifting her up and then leaving her almost dry, would infallibly make her graze the sand-banks.
