"This afternoon the lorcha will be towed behind the breakwater. She'll be in strict quarantine. You'll be in charge. I'll give you disinfectants and medicines. You'll keep the boat clean, and you'll attend the sick. Whenever somebody tumbles over, run up the yellow flag and we'll come after him as soon as we can. Every morning I'll come around and see how you are getting along." "How long will it last?" asked Jerry. "Don't know. Till they're all gone, perhaps. There must be five days' quarantine after each case. If they die close together, it will be short. If they go five days apart, it may last six months. Six months to make a man of you, Jerry; will you do it?" "It will be hell," said Jerry, with a tense smile. "It will be hell," acquiesced the surgeon. "You must work, Jerry." "I'll do it," said Jerry. * * * * * That afternoon the lorcha was towed behind the breakwater, and at sunset a woman who was lighting the fire for the evening meal whirled on her heels and slapped the deck with the whole length of her body. Jerry ran up the yellow flag, but the night had dropped like a thunderbolt, and it was not seen from shore; so he cared for her till morning. She was old and knotted and decrepit; her teeth were gone, and she was loathesomely unclean, but he worked over her with rigid patience, not ceasing for a moment, for the Demon was already clutching at him. At dawn a boat pulled up and the woman was lowered into it, still alive. Then the sun rose, blinding hot, and Jerry paced the deck furiously. The groups of sleepers on deck were disentangling beneath the stinging announcement of the new day, and they scattered in awe before the strange Americano, tugging among them with great steps that were almost leaps. At last a little steamer appeared at the mouth of the river; it slid along on the other side of the breakwater, turned at the end, and chugged alongside the lorcha. It was the doctor's launch. Burke stepped to the bulwarks and looked down at the boat wallowing in the cross-seas. Huntington was standing on the rail, his right hand against the side of the lorcha, his body giving easily to every shock; and Burke gazed hungry-eyed at his cool, alert demeanour. "Well, how goes it?" asked the surgeon. "One case," said Burke, calmly. "That means five days more. What is it?" "A woman; she's at the hospital now," he answered, in the same rigid, subdued tone. "And you?" asked the surgeon. "For God's sake," cried Burke, his voice breaking into frenzy, "give me something to do, something to do!" "All right, old man," answered Huntington, showing no surprise. "Throw us a rope." Burke threw a rope. A case was tied to it and hauled on deck. "Chlorodyne," announced the surgeon. The rope was thrown back. A demijohn was hauled up, then another, and another. "Carbolic," shouted Huntington. "Disinfect the boat." "All right; good-by," said Burke. The doctor waved his hand, and the launch churned away.
