Fitz watched the sick man as he drained the cup.

“Ah! Bitter stuff! If you just think of the bitterest thing you ever tasted and multiply it by itself, square it, as we used to call it at school, you would only come near to the taste of this. But it’s not a nasty bitter, sickly and nauseous and all that, but a bitter that you can get almost to like in time.—Thank you, Poole,” and he handed back the cup. “It makes me feel better at once. Nasty things, these fevers, Squire Burnett, and very wonderful too that a man, a strong man, should be going about hale and hearty in these hot countries, and then breathe in something all at once that turns him up like this. And then more wonderful still that the savage people lower down yonder in South America—higher up, I ought to say, for it was the folk amongst the mountains—should have found out a shrub whose bark would kill the fever poison and make a man himself again. They say—put the cup away, Poole—that wherever a poisonous thing grows there’s another plant grows close at hand which will cure the ill it does, bane and antidote, my lad, stinging-nettles and dock at home, you know. I don’t know that it holds quite true, but I do know that there are fevers out here, and quinine acts as a cure. But there’s one thing I want to know, and it’s this, how in the name of all that’s wonderful these South American people first found it out.”

Fitz looked at him in a puzzled way. “What does he mean,” he thought, “by wandering off into a lecture like this?” The skipper smiled at him as if he read his thoughts. “Hah!” he said. “I am beginning to feel better now. The shivers are going off. Not such a bad doctor, am I? You see, one always carries a medicine-chest, but one has to learn how to use it, and I have been obliged to pick up a few things. I shouldn’t be at all surprised some day if I have to doctor you for something more than a crack on the head. Look here, Poole,” he continued, with a broad, good-humoured smile crossing his features, “come into consultation. What do you think? Our friend here is a bit too hot-blooded. Do you think he need be bled? No, no; don’t flush up like that, my lad. It was only my joke. There,” he cried, holding out his hand, which had ceased to tremble—“shake. I’ll never allude to it again. You did rather a foolish thing, but it is all over now—dead and buried, and we are going to be just as good friends as we were before, for I like you, my lad, none the less for the stuff of which you are made—the pluck you have shown. But take my advice; don’t attempt anything of the kind again. Fate has put you into this awkward position. Be a man, and make the best of it. Some day or other you will be able to say good-bye to us and go back to your ship, feeling quite contented as to having done your duty. Come now, let’s shake hands and begin again.”

He held out his hand once more, and after a moment’s hesitation, Fitz, who dared not trust himself to speak, placed his own within it, to have it held in a firm, warm pressure for some moments before it was released.

“There,” said the skipper, smiling, “I am coming out in a nice soft perspiration now, and I feel as if that bit of excitement has done me good. Here, Poole, I’m tired, and I think that I can sleep and wake up better. Burnett, my lad, perhaps you would like to stay below the rest of the day.—Poole, mix Mr Burgess a dose. You know how many grains. Tell him I can’t come to him myself, and see that he takes it. It’s my orders, mind. These attacks are sharp but short. I’m half asleep already. Oh, by the way—”

He stopped short, drawing a heavy breath.

“By the way, I—”

He was silent again.

“I—Poole.”

“Yes, father,” said the lad softly.
