"But I think it's heroic of you," said Roger. "Are there many of you out there, doing this?"
"Not very many."
"It's a heroic thing to do," said Roger. "Heroic. The loneliness alone must make it heroic."
"You get used to the loneliness. It gives you nerves at first. But in my opinion the heat keeps you from thinking much about the loneliness. I like heat myself, but it takes it out of most of the griffs. The heat can be pretty bad."
"All the same, it is a wonderful thing to do."
"Yes. It's a good thing to spot the cause of a disease like that. But you over-rate the heroic part. It's all in the day's work. One takes it as it comes, and one has a pretty good time, too. One never thinks of the risk, which is really very slight. Doctors face worse things in London every day. So do nurses. A doctor was telling me only the other day how a succession of nurses went down to a typhus epidemic and died one after the other. There's nothing like that in the Protectorate with sleeping sickness."
"But being the only white man, away in the wilds, with the natives dying all round you!"
"Yes. That is pretty bad. I was in the middle of a pretty bad outbreak in a little place called Ikupu. It was rather an interesting epidemic, because it happened in a place where there weren't any of the tsetse which is supposed to do the harm. They may have been there; but I couldn't find any. It must have been another kind which did the damage at Ikupu. As a matter of fact, I did find trypanosomes in another kind there, which was rather a feather in my cap. Well, I was alone there. My assistant died of blackwater fever. And there I was with a sleeping village. There were about twenty cases. Most of the rest of the natives ran away, and no doubt spread the infection. Those twenty cases were pretty nearly all the society of Ikupu. Some were hardly ill at all. They just had a little fever, perhaps, or a skin complaint on the chest, and tender, swollen glands. Others were just as bad as they could be. They were in all stages of the disease. Some were just beginning to mope outside their huts. Others were sitting still there, not even caring to ask for food, just moping away to death, with their mouths open. Generally, one gets used to seeing that sort of thing; but I got nerves that time. You see, they were rather a special tribe at Ikupu. They called themselves Obmali, or some such name. Their lingo was rather rummy. Talking with the chief I got the impression that they were the relics of a tribe which had been wiped out further west. They believed that sleeping sickness was caused by a snake-woman in a swampy part of the forest. Looking after all those twenty people, and taking tests from them, gave me fever a good deal. That is one thing you have to get used to—fever. You get used to doing your work with a temperature of one hundred and two degrees. It's queer about fever. Any start, or shock, or extra work, may bring it on you. I had it, as I said, a good deal. Well, I got into the way of thinking that there was a snake-woman. A woman with a puff-adder head, all mottled. I used to barricade my hut at night against her."
Dr. Heseltine drew his chair up. "What are you two discussing? Talking about sleeping sickness?" he asked. "How does the new treatment suit you, Lionel? No headache, I hope? It's apt to make you headachy. There's a subject for a play for you, Mr. Naldrett. 'Man and the Trypanosome.' You could bring the germs on to the stage, and kill them off with a hypodermic syringe."
"Yes," said Roger. "It has all the requirements of a modern play: strength, silence, and masculinity. There's even a happy ending to it."
