"I ought to do it," he said, "and I will. It only wants pluck, for I have got right on my side. It is almost as good as having the gunboat and her crew at my back. It's one of those chances such as we read of in history, where one fellow steps out to the front and carries all before him. I did not see it so clearly before as I do now. That's what I ought to do, and I am going to do it. Poole will think it abominably ungrateful, and his father will be horribly wild; but I have got my duty to do, and it must be done, so here goes." But "here" did not go, for on second thoughts matters did not seem quite so clear; but a day or two after, when the notion had been steadily simmering in his mind it seemed at last to be quite done, and shutting his eyes to all suggestions regarding impossibility or madness, he made his plunge. Fitz was not well. The weather had grown intensely hot, and unconsciously he was suffering from a slight touch of fever, which he complained about to Poole, who explained to him what it was, after reference to his father, and came back to him with a tiny packet of white crystals in some blue paper, and instructions that he was to take the powder at once. "Fever, is it?" said Fitz, rather sourly. "One couldn't be catching fever out here in the open sea. I shall see your father myself. Why didn't he come on deck yesterday?" "Because he isn't well. He's got a touch of fever too. He had got the bottle out of the medicine-chest, and was taking a dose when I went into his cabin." "What!" cried Fitz. "Then he's caught the fever too?" "Oh no; he caught it years ago, on the Mosquito Coast, and now and then when we get in for a change of weather like we have just had, it breaks out again and he's very ill for a few days; but he soon comes round." "But I was never on the Mosquito Coast," cried Fitz impatiently. "I never caught a fever there, and I couldn't catch one like that of your father." "No," said Poole; "father was talking about it, and he said yours was a touch due to your being susceptible after being so much hurt. That's how he said it was. Now then, come down to the cabin and take your physic like a good boy." "I am not going to do anything of the sort," said Fitz shortly. "I took plenty while I was ill and weak, and you could do what you liked with me. But I am strong enough now, and if what I feel is due to the weather, when it changes the trouble will soon go off." "I dare say it will," said Poole, laughing; "but you needn't make a fuss about swallowing this little scrap of bitter powder. Come on and take it like a man." "Don't bother," said Fitz shortly, and he walked away right into the bows, climbed out on to the bowsprit, and sat down to think. "He's a rum chap," said Poole, as he stood watching him, and putting the powder back into his pocket. "He makes me feel as if I liked and could do anything for him sometimes, and then when he turns cocky I begin to want to punch his head."
