"Did you feel you ought to come after you noted this?"

"Before," said Wyndham, dryly. "I didn't know the glass had dropped until I got a light, but it looks as if I might have stayed below. However, since I have turned out, we'll haul down the main-topsail."

He gave an order and two Krooboys got to work. There was no obvious reason for lowering the sail, but when Wyndham ordered the negroes obeyed. Although they grinned with frank good-humor when Marston talked to them, he knew he did not share Wyndham's authority. Yet Harry was not harsh.

When the sail was lowered Wyndham looked about. Some of the scattered clouds had rolled together and the sky was black over the land. One could scarcely feel the light wind, but the surf had got louder. Its roar came out of the dark as if heavy trains were running along the coast.

"It looks ridiculous, particularly since I'd like to edge her farther off the beach, but I think we'll stow the mainsail and fore-staysail," Wyndham remarked.

Marston agreed. Although he could see no grounds for shortening sail, he trusted Wyndham's judgment, and the Krooboys got to work again. The ropes, however, were stiff and swollen with the dew, and the mainsail came down slowly. The heavy folds of canvas caught between the topping-lifts; the gaff-jaws jambed on the mast. Wyndham sent a man aloft to sit upon and ride down the spar, but this did not help much, and the boom along the foot of the sail lurched with violent jerks. Blocks banged and loose ropes whipped across the deck. The sweat ran down Marston's face; he wanted to finish the job. For one thing, Columbine was unmanageable while the half-lowered canvas flapped about.

Stopping a moment for breath, he glanced over the rail. The long swell sparkled with small points of light that coalesced in sheets of green flame when the undulations broke against the schooner's side. The deck was spangled with luminous patches by the splashes and the wake that trailed astern was bright. Columbine stole through the water although the wind had nearly gone. It was not worth while to bring her head-to when they shortened sail.

Then the helmsman shouted and Marston felt one side of his face and body cool. The loose canvas flapped noisily. Its folds shook out and swelled, and Marston seized a rope. His skin prickled; he felt a strange tension and a feverish desire to drag down the sticking gaff. A few moments afterwards, something flickered behind the sail and a peal of thunder drowned the noise on board. When it died away, rolling hull, slanted masts, and the figures of the men stood out, wonderfully sharp, against a dazzling blaze that vanished and left bewildering dark. The next peal of thunder deafened Marston, who thought Wyndham shouted but heard no words. This did not matter, because he knew they must secure the sail before the tornado broke, and he pulled at the downhaul. He could not hear the wind for the thunder, but it had begun to blow.

The sail swelled between the confining ropes, there was a noise on one side of the yacht, water foamed along the planks, and she began to swing. It looked as if the steersman were putting up the helm. The peak of the gaff was nearly down; with another good pull they could seize it and lash it to the boom. Then a dazzling flash touched the deck. Marston saw Wyndham run aft and push the Kroo from the wheel, but this was the last he saw clearly for sometime. He imagined the fellow had meant to run the yacht off before the squall; one could ease the strain of a sudden blast like that, but if the squall lasted, they could not shorten sail while she was before the wind. Now she was coming round. Wyndham had put the helm down. It looked as if he were too late.

The tornado broke upon her side and she went over until her lee rail was in the sea. There was a noise like a thunder-clap forward as a sail blew away; Marston thought it was the jib. He could see nothing. It had got impenetrably dark, but he had a vague notion that water rushed along the deck and the mainsail had broken loose and blown out between the ropes. Unless they could master it, the mast would go. He heard another report forward and thought somebody had loosed the staysail halyards and the sail had blown to rags. Although his eyes were useless, he knew what was going on.
