"I am sure he has not."

They crept into their hammocks, but not to sleep, and they were wide awake when Mr. Hume entered noisily some two hours later.

"To-morrow night," he shouted boisterously.

"With pleasure, and the night after, for good visitors are rare,"

called the Belgian.

"And good hosts also. Touching those two men you promised as the crew for my boat?"

"They will be here to-morrow evening," said the senior officer, thrusting a head round the mat. "Ah, you are comfortable, eh? Yes, I sent a messenger to Ha.s.san's camp by the vessel which brought you.

Rest well."

"They are good fellows, these Arabs," said Mr. Hume, with enthusiasm--"good fellows. I remember once----"

"To-morrow night," said the officer, as he withdrew, laughing.

Mr. Hume hummed cheerfully as he prepared for bed, taking no notice of his young comrades, who were regarding him with silent disfavour. With one yawn after another he blew out the light, and struggled into his hammock, to fall asleep almost at once.

Venning's uneasiness returned. He tossed restlessly, listening to the unaccustomed noises from without, and as the hours went by, and at last the sound of talking about the fires died off in a lazy drone, the desire to see what had become of Muata was too strong to resist. Softly he lowered himself to the earth-floor, but, soft as he moved, others had heard.

"Are the mosquitoes troublesome?"

Venning started at the deep voice so unexpected. "I did not know you were awake, sir."

"I sleep very lightly my boy."

"As you are awake, sir, I would like to say----"

But he stopped as the mat rustled.

"Come in," said Mr. Hume.

"Me guard, great master"--in the same soft, oily tones Venning had heard before. "Hear noise. Think may be thieves."

"Mosquitoes, not thieves," said Mr. Hume, quietly. "Bring a light."

The Zanzibar boy complied, and, holding a taper above his head, looked not for mosquitoes, but at the rifles in the corner.

"The skeeters, master," he muttered, with an evil squint at Compton, who was blinking at the light.

"Better get back into your hammock, Venning. You can go, boy; and keep a good watch, for we are coming to the thieves' hour."

The man showed his white teeth in a grin as he withdrew.

"Don't stir from your hammocks until I do," said Mr. Hume, very sternly, in a whisper; then louder, "Good night, Venning."

"Good night, sir," said Venning, convinced that the master was alive to the game, and more easy in his mind.

As he dropped off to sleep he heard the wail of a jackal, and next he was awakened by the sound of a native chanting. It was already daybreak, and Mr. Hume stood on the verandah, having drawn the mats aside.

The sun, striking under the thatch, shone on the hunter's tawny hair and beard, and Venning wondered how for a moment he could have doubted the courage of a man with such a lion-like head. But he was to receive another shock.

"Silence, dog!" roared the hunter, addressing the singer, evidently.

Compton, who was sitting on his hammock dressing, looked out.

"By Jove," he muttered, "he's shouting at Muata!"

Venning jumped down to the floor and looked out. Muata was still bound to the post, and, with his face to the sun, was chanting his words of greeting or of farewell in tones that lacked the deep chest-notes of his war-cry.

One of the natives, hearing the order of the white man, flung a stick at the chief with an insult; but Muata, nothing heeding, sang on his slow song in a voice that was almost like a woman's.

"Must white men lose their sleep because a robber is to die?" roared the hunter again.

Venning s.n.a.t.c.hed up a beaker of water and ran out barefooted. He held the water to the chiefs mouth. Muata turned his smouldering eyes on the boy, sucked in a mouthful of the water, and then shot it out over Venning's outstretched arm.

Venning dropped the mug, and went back with a red face to see the two officers regarding him with sour faces.

"Serve you right," shouted Mr. Hume, in apparent fury. "When will you learn to treat a black like the brute he is?"

"Quite so," said the senior officer, showing himself. "I am glad to find you have no ridiculous sentiment."

"Ah! good morning, my friend," said Mr. Hume, heartily. "As for my young comrade, you must pardon him."

"He has his lesson," said the officer, dryly, as he pointed to the soaked pyjama.

"The man woke me with his singing. I have seen men shot for less than that."

"In good time," said the officer, with a sinister look, "the accusers will be here to-night, and to-morrow"--he made a gesture-- "to-morrow you can also choose the two men you need for your boat's crew."

After breakfast, Mr. Hume had an opportunity of speaking without the fear of being overheard, for they finished putting the Okapi together, and worked her out by the levers into the river, where she gleamed in the sun.

"I dare say you think I am a brute," he said, "and I don't blame you; but if we mean to save Muata's life, we must appear to be altogether indifferent to his fate. Those men are keeping a close watch on us."

"I know it," said Compton.

"You do, eh?"

"That Zanzibar boy was spying on us last night before you came, and he tried to get us to bribe him to free Muata."

"I hope you were not so foolish as to fall into the trap?" said the hunter, sharply.

"I kicked him out of the place," said Compton. "I told Venning you were playing a game for Muata's life."

"You did me justice?" said Mr. Hume, with his gaze on Venning.

"It seemed to me terrible to leave him without a word of encouragement," said the boy; "but I am awfully sorry I doubted you, sir."
