"For I told you, Ranabini," said an exasperated Sanders, "that you should keep the upper channel free from trees and branches, and I have paid you many bags of salt for your services."

"Lord, it is so," said Ranabini, scratching his brown leg thoughtfully.

"At the full of the moon, before the rains, did I not ask you if the channel was clear, and did you not say it was like the street of your village?" demanded Sanders, in wrath.

"Lord," said Ranabini frankly, "I lied to you, thinking your lordship was mad. For what other man would foresee with his wonderful eye that rains would come? Therefore, lord, I did not think of the upper channel, and many trees floated down and made a little dam. Lord, I am an ignorant man, and my mind is full of my own brother, who has come from a long distance to see me, for he is a very sick man."

Sanders's mind was occupied by no thought of Ranabini's sick brother, as the dazzling white _Zaire_ went thrashing her way down stream. For he himself was a tired man, and needed rest, and there was a dose of malaria looming in the offing, as his aching head told him. It was as though his brains were arranged in slats, like a venetian blind, and these slats were opening and closing swiftly, bringing with each lightning flicker a momentary unconsciousness.

Captain Hamilton met him on the quay, and when Sanders landed--walking a thought unsteadily, and instantly began a long and disjointed account of his adventures on a Norwegian salmon river--Hamilton took him by the arm and led the way to the bungalow.

In ten minutes he was a.s.sisting Sanders into his pyjamas, Sanders protesting, albeit feebly, and when, after forcing an astonishing amount of quinine and a.r.s.enic down his chief's throat, Hamilton came from the semi-darkness of the bungalow to the white glare of the barrack square, Hamilton was thoughtful.

"Let one of your women watch by the bed of the lord Sandi," said he to Sergeant Abiboo, of the Houssas, "and she shall call me if he grows worse."

"On my life," said Abiboo, and was going off.

"Where is Tibbetti?" asked Hamilton.

The sergeant turned back and seemed embarra.s.sed.

"Lord," he said, "Tibbetti has gone with the lady, your sister, to make a palaver with Jimbujini, the witch-doctor of the Akasava. They sit in the forest in a magic circle, and lo! Tibbetti grows very wise."

Hamilton swore under his breath. He had ordered Lieutenant Tibbetts, his second-in-command, prop, stay, and aide-de-camp, to superintend the drill of some raw Kano recruits who had been sent from the coast.

"Go tell the lord Tibbetti to come to me," he said, "but first send your woman to Sandi."

Lieutenant Tibbetts, with his plain, boyish face all red with his exertions, yet dignified withal, came hurriedly from his studies.

"Come aboard, sir," he said, and saluted extravagantly, blinking at his superior with a curious solemnity of mien which was his own peculiar expression.

"Bones," said Hamilton, "where the d.i.c.kens have you been?"

Bones drew a long breath. He hesitated, then--

"Knowledge," he said shortly.

Hamilton looked at his subordinate in alarm.

"Dash it, you aren't off your head, too, are you?"

Bones shook his head with vigour.

"Knowledge of the occult, sir and brother-officer," he said. "One is never too old to learn, sir, in this jolly old world."

"Quite right," said Hamilton; "in fact, I'm pretty certain that you'll never live long enough to learn everything."

"Thank you, sir," said Bones.

The girl, who had had less qualms than Bones when the summons arrived, and had, in consequence, returned more leisurely, came into the room.

"Pat," said her brother, "Sanders is down with fever."

"Fever!" she said a little breathlessly. "It isn't--dangerous?"

Bones, smiling indulgently, soothed her.

"Nothin' catchin', dear Miss Patricia Hamilton," he began.

"Please don't be stupid," she said so fiercely that Bones recoiled. "Do you think I'm afraid of catching anything? Is it dangerous for Mr.

Sanders?" she asked her brother.

"No more dangerous than a cold in the head," he answered flippantly. "My dear child, we all have fever. You'll have it, too, if you go out at sunset without your mosquito boots."

He explained, with the easy indifference of a man inured to malaria, the habits of the mosquito--his predilection for ankles and wrists, where the big veins and arteries are nearer to the surface--but the girl was not rea.s.sured. She would have sat up with Sanders, but the idea so alarmed Hamilton that she abandoned it.

"He'd never forgive me," he said. "My dear girl, he'll be as right as a trivet in the morning."

She was sceptical, but, to her amazement, Sanders turned up at breakfast his usual self, save that he was a little weary-eyed, and that his hand shook when he raised his coffee-cup to his lips. A miracle, thought Patricia Hamilton, and said so.

"Not at all, dear miss," said Bones, now, as ever, accepting full credit for all phenomena she praised, whether natural or supernatural. "This is simply nothin' to what happened to me. Ham, dear old feller, do you remember when I was brought down from the Machengombi River? Simply delirious--ravin'--off my head."

"So much so," said Hamilton, slicing the top off his egg, "that we didn't think you were ill."

"If you'd seen me," Bones went on, solemnly shaking one skinny forefinger at the girl, "you'd have said: 'Bones is for the High Jump.'"

"I should have said nothing so vulgar, Bones," she retorted. "And was it malaria?"

"Ah," said Hamilton triumphantly, "I was too much of a gentleman to hint that it wasn't. Press the question, Pat."

Bones shrugged his shoulders and cast a look of withering contempt upon his superior.

"In the execution of one's duty, dear Miss Patricia H," he said, "the calibre of the gun that lays a fellow low, an' plunges his relations an'

creditors into mournin', is beside the point. The only consideration, as dear old Omar says, is--

"'The movin' finger hits, an', havin' hit, Moves on, tum tumty tumty tay, And all a feller does won't make the slightest difference.'"

"Is that Omar or Shakespeare?" asked the dazed Hamilton.

"Be quiet, dear. What was the illness, Bones?"

"Measles," said Hamilton brutally, "and German measles at that."

"Viciously put, dear old officer, but, nevertheless, true," said Bones buoyantly. "But when the hut's finished, I'll return good for evil.

There's goin' to be a revolution, Miss Patricia Hamilton. No more fever, no more measles--health, wealth, an' wisdom, by gad!"

"Sunstroke," diagnosed Hamilton. "Pull yourself together, Bones--you're amongst friends."

But Bones was superior to sarcasm.
