Jack observed that something unpleasant was going on; but he was too much occupied with watching the position of the ship to interfere, as were the other officers. Billy himself also had presently to hurry forward to attend to his duties, while the major and his wife and daughters retired to their cabins to discuss the matter.

By this time heavy rollers were coming in, breaking within a cable’s length of the ship on each quarter, making her position far from pleasant. There was but a light air from the southward, insufficient to enable her get under way.

Jack much regretted having come to the place, for it was evidently a far from satisfactory one for landing troops. The cutter was now lowered, and sent round the ship to sound. On her return on board the master reported only seven fathoms close to the breakers. The breeze now freshened from east-south-east, but the rollers increasing, the sea broke heavily half a cable’s length from her. Everything was now prepared for making sail. On the cable being shortened in, it was discovered that it had swept over a rock about fifty fathoms from the anchor, and that at any moment it might give way.

“Stop heaving!” cried the captain. “Make ready to slip!” The sails were loosened; but as they were about to be sheeted home, the cable parted. Instantly the sheet anchor was let go. For some seconds it seemed doubtful, before it could reach the bottom, whether the ship would strike on the rocks; but it happily brought her up, though fearfully near them.

By this time it was again night; the rollers had greatly increased, and should the sheet anchor give way, it was clear that nothing could save the ship. Jack had seldom been in so anxious a position. All on board saw the danger they were in. The major’s cheek lost its ruddy hue, and even Mrs Bubsby’s countenance exhibited signs of alarm. Not far off lay a small vessel with both anchors down. Her master coming on board volunteered to make a hawser fast to her for the purpose of casting the man-of-war the right way.

The engineer stated that it would be some hours before steam could be got up.

“Then let me advise you, sir, to get under way forthwith,” said the master of the merchantman. “Should the anchor fail to hold, the ship must inevitably strike on that reef of rocks where the surf is breaking so furiously, and where, strong as she may be, she will not hold together for an hour, while there will not be the slightest chance of saving a single human life.”

Jack gladly accepted the worthy master’s offer. The cutters were lowered, and hawsers carried to the vessel. The sheet anchor was then weighed, when, on its coming above water, it was found that both the flukes had gone. Her only hope of safety was on the remaining anchor. Would it hold until sail could be made? From the direction the beats were drifting it was soon seen that, in spite of all the efforts of their crews, it would be impossible to carry the hawsers to the merchantman. Jack looked anxiously at the compass and dog vanes. He knew full well that at any moment the cable might part, and, should the ship not cast the right way, she must be driven on the rocks and every soul perish.

“I would advise you to return on board your own vessel, my friend,” he said to the master of the merchantman. “You will be safer on board her than here.”

“Now is your chance, captain,” exclaimed the master, as the wind veered a point well to the eastward.
