Although the sky was unchanged they could see the light cloud Edgar had noticed advancing towards them at an extraordinary rate of speed, while a white line on the sea kept pace with it.

"Hard up with the helm—hard up!" Wilkinson shouted. "Hold on a moment with those head sails; that will do, that will do. Let go the halliards; down staysails and jib."

The sailors, now conscious of the coming danger, worked desperately. The light upper sails were secured, the courses had been clewed up, but the topsails were still but half-lashed when Wilkinson shouted again:

"Down for your lives! Down on the weather side; slip down by the back-stays. You men to leeward, hold on—all hold on," he shouted a few seconds later.

There was a dull roaring sound, rising to a shriek as the squall struck the vessel.

Most of the men had gained the deck in safety, but many of those coming down by the ratlines were still some distance from the deck. It was well for them that they were on the weather side; had they been to leeward they would have been torn from their grasp, whereas they were now pinned to the rigging. Two sounds like the explosion of cannon were heard. The main and foretopsails both blew out of their gaskets, bellied for an instant, and then burst from the bolt-ropes and flew away, and were speedily lost to sight. So great was the pressure that the brig was driven bodily down until the water was almost level with the rail at the bow, and it looked for a moment as if she would go down by the head.

One of the jibs was run up, but only to be blown away before it was sheeted home. Another was tried, the sheet being kept very slack. This held, her head lifted, and in a minute the Tigress was flying along dead before the wind. The storm-jib was brought up, hooked on, and hoisted. This, being of very heavy canvas, could be trusted, and as soon as it was set the other was hauled down.

"Thank God, that is over!" Wilkinson said, "and we have not lost a hand."

By this time all the men had gained the deck.

"How long will this last?" Edgar shouted in one of the Turks' ears.
