"Thank you," said Sanders. "You had better practise on Hamilton."
"Don't come near me!" threatened Hamilton.
It was Patricia who, when the tea-things had been removed, played the heroine.
"Take mine," she said, and extended her hand.
Bones found a needle, and sterilized it in the flame of a spirit lamp.
"This won't hurt you," he quavered, and brought the point near the white, firm flesh. Then he drew it back again.
"This won't hurt you, dear old miss," he croaked, and repeated the performance.
He stood up and wiped his streaming brow.
"I haven't the heart to do it," he said dismally.
"A pretty fine doctor you are, Bones!" she scoffed, and took the needle from his hand. "There!"
Bones put the tiny crimson speck between his slides, blobbed a drop of oil on top, and focussed the microscope.
He looked for a long time, then turned a scared face to the girl.
"Sleepin' sickness, poor dear old Miss Hamilton!" he gasped. "You're simply full of tryps! Good Lord! What a blessin' for you I discovered it!"
Sanders pushed the young scientist aside and looked. When he turned his head, the girl saw his face was white and drawn, and for a moment a sense of panic overcame her.
"You silly ass," growled the Commissioner, "they aren't trypnosomes! You haven't cleaned the infernal eyepiece!"
"Not trypnosomes?" said Bones.
"You seem disappointed, Bones," said Hamilton.
"As a man, I'm overjoyed," replied Bones gloomily; "as a scientist, it's a set-back, dear old officer—a distinct set-back."
The house-warming lasted a much shorter time than the host had intended. This was largely due to the failure of a very beautiful experiment which he had projected. In order that the rare and wonderful result at which he aimed should be achieved, Bones had the hut artificially darkened, and they sat in a hot and sticky blackness, whilst he knocked over bottles and swore softly at the instruments his groping hand could not discover. And the end of the experiment was a large, bad smell.
"The women and children first," said Hamilton, and dived for the door.
They took farewell of Bones at a respectful distance.
Hamilton went across to the Houssa lines, and Sanders walked back to the Residency with the girl. For a little while they spoke of Bones and his newest craze, and then suddenly the girl asked—
"You didn't really think there were any of those funny things in my blood, did you?"
Sanders looked straight ahead.
"I thought—you see, we know—the tryp is a distinct little body, and anybody who had lived in this part of the world for a time can pick him out. Bones, of course, knows nothing thoroughly—I should have remembered that."
She said nothing until they reached the verandah, and she turned to go to her room.
"It wasn't nice, was it?" she said.
Sanders shook his head.
"It was a taste of hell," he said simply. And she fetched a quick, long sigh and patted his arm before she realized what she was doing.
Bones, returning from his hut, met Sanders hurrying across the square.
"Bones, I want you to go up to the Isisi," said the Commissioner. "There's an outbreak of some weird disease, probably due to the damming of the little river by Ranabini, and the flooding of the low forests."
Bones brightened up.
"Sir an' Excellency," he said gratefully, "comin' from you, this tribute to my scientific–"
"Don't be an ass, Bones!" said Sanders irritably. "Your job is to make these beggars work. They'll simply sit and die unless you start them on drainage work. Cut a few ditches with a fall to the river; kick Ranabini for me; take up a few kilos of quinine and dose them."
Nevertheless, Bones managed to smuggle on board quite a respectable amount of scientific apparatus, and came in good heart to the despondent folk of the Lower Isisi.
Three weeks after Bones had taken his departure, Sanders was sitting at dinner in a very thoughtful mood.
Patricia had made several ineffectual attempts to draw him into a conversation, and had been answered in monosyllables. At first she had been piqued and a little angry, but, as the meal progressed, she realized that matters of more than ordinary seriousness were occupying his thoughts, and wisely changed her attitude of mind. A chance reference to Bones, however, succeeded where more pointed attempts had failed.
"Yes," said Sanders, in answer to the question she had put, "Bones has some rough idea of medical practice. He was a cub student at Bart.'s for two years before he realized that surgery and medicines weren't his forte."
"Don't you sometimes feel the need of a doctor here?" she asked, and Sanders smiled.
"There is very little necessity. The military doctor comes down occasionally from headquarters, and we have a native apothecary. We have few epidemics amongst the natives, and those the medical missions deal with—sleep-sickness, beri-beri and the like. Sometimes, of course, we have a pretty bad outbreak which spreads–Don't go, Hamilton—I want to see you for a minute."
Hamilton had risen, and was making for his room, with a little nod to his sister.
At Sanders's word he turned.
"Walk with me for a few minutes," said Sanders, and, with an apology to the girl, he followed the other from the room.
"What is it?" asked Hamilton.
Sanders was perturbed—this he knew, and his own move towards his room was in the nature of a challenge for information.
"Bones," said the Commissioner shortly. "Do you realize that we have had no news from him since he left?"
Hamilton smiled.
"He's an erratic beggar, but nothing could have happened to him, or we should have heard about it."
Sanders did not reply at once. He paced up and down the gravelled path before the Residency, his hands behind him.
"No news has come from Ranabini's village for the simple reason that nobody has entered or left it since Bones arrived," he said. "It is situated, as you know, on a tongue of land at the confluence of two rivers. No boat has left the beaches, and an attempt to reach it by land has been prevented by force."
