"Oh, shut up!" he said. "We've heard all that before, and you don't do it very well. If I could get back into the shop the governor found me I'd like to catch myself going to sea. Oh, great handspikes! Just listen to the brute."

A storm of venomous language came forward from the poop, and through the drowsy flap of canvas and stillness of the dazzling ocean there rang the strident voice of the mate. Lawson slowly shook his head.

"She was scarcely steering, and Biddulph has let her fall off," he said. "They've stood a good deal forward, but that mate of ours is pushing them too far."

Then there was silence that seemed deepened by the light flap and rustle of sailcloth and gurgle of shining brine, but the peace of the day had gone, and the shadow which crept into the four young faces was that which has darkened so many lives at sea. They had all been used to discipline, and did not resent it, while it had been made evident to two of them of late that on board a sailing ship toil that is brutal as well as perilous is often a necessity. They would also have undertaken it more or less cheerfully, but there had been added to it a ruthless tyranny, and Appleby's little sigh seemed to ask the question that downtrodden men have asked from the beginning—why such things must be? And, for he was young, he could not find an answer.

A little breeze sprang up after sunset, and the ship was sliding faster through a sea that blazed about her with lights of green and gold when Appleby hung about the deck, held still and silent by something in the harmonies of the night. There was no moon, but there was also no cloud in the sky, and the great stars the mast-heads swayed across hung set far back one behind the other in the blue, while the spires of canvas towered black and sharp under their cold light. Not a cloth rustled, but there came down from the gossamer tracery of rigging a little musical humming that suggested the chanting of an invisible choir.

Forward a black figure was visible on the forecastle. Here and there another showed along the dusky line of bulwarks, and now and then Appleby could see the dark shape of the mate standing high upon the poop. This, however, was not often, because he preferred to keep the great shadowy mainsail between himself and it. Night and sea were still and peaceful, and that sinister figure alone jarred upon their serenity.

Suddenly the harsh voice he feared broke the silence, and Appleby instinctively set his lips when he saw his comrade cross the deck. It was noticeable that Niven went at a trot, and if he had been told that one side of the poop is usually sacred to the officer of the watch knowing that haste was advisable he forgot. A moment or two later he stood panting at the head of the ladder, which rose about six feet from the deck, and the mate strode towards him with arm drawn back. Possibly something had ruffled his temper, which was at the best a bad one, that night.

"There are two ladders to this poop, and this will teach you which is yours," he said.

Then before Niven could speak the arm shot out, and the breathless lad reeled backwards with head swimming and a tingling face. The blow had possibly not been a very cruel one, but the Aldebaran swung her stern up just then, and the opening in the rails was close behind him. He went out through it backwards, caught his foot on the rung of the ladder, and pitching over came down with a sickening thud on deck. Appleby, who had seen it all, ran aft and knelt down beside him.

"Chriss, are you hurt?" he gasped.
