"If they fight amongst themselves--yes," said Captain Hamilton; "if they fight outsiders, there will be plenty of bleats. Why not send Bones to overlook his sugar experiments," he added.

"Let's talk about something pleasant," said Bones hastily.

It was exactly three months later when he actually made the trip.

"Take the _Zaire_ up to the bend of the Isisi," said Sanders one morning, at breakfast, "and find out what Ali Kano is doing--the lazy beggar should have reported."

"Any news from the N'gombi?" asked Hamilton.

"Only roundabout stories of their industry. Apparently the sugar merchant is making big experiments. He has set half the people digging roots for him. Be ready to sail at dawn."

"Will it be a dangerous trip?" asked the girl.

"No. Why?" smiled Sanders.

"Because I'd like to go. Oh, please, don't look so glum! Bones is awfully good to me."

"Better than a jolly old brother," murmured Bones.

"H'm!" Sanders shook his head, and she appealed to her brother.

"Please!"

"I wouldn't mind your going," said Hamilton, "if only to look after Bones."

"S-sh!" said Bones reproachfully.

"If you're keen on it, I don't see why you shouldn't--if you had a chaperon."

"A chaperon!" sneered Bones. "Great Heavens! Do, old skipper, pull yourself together. Open the jolly old window and give him air. Feelin'

better, sir?"

"A chaperon! How absurd!" cried the girl indignantly. "I'm old enough to be Bones's mother! I'm nearly twenty--well, I'm older than Bones, and I'm ever so much more capable of looking after myself."

The end of it was that she went, with her Kano maid and with the wife of Abiboo to cook for her. And in two days they came to the bend of the river, and Bones pursued his inquiries for the missing spy, but without success.

"But this I tell you, lord," said the little chief who acted as Sanders's agent, "that there are strange things happening in the N'gombi country, for all the people have gone mad, and are digging up their teeth (tusks) and bringing them to a white man."

"This shall go to Sandi," said Bones, realizing the importance of the news; and that same evening he turned the bow of the _Zaire_ down stream.

Thus said Wafa, the half-breed, for he was neither foreign Arab nor native N'gombi, yet combined the cunning of both--

"Soon we shall see the puc-a-puc of Government turn from the crookedness of the river, and I will go out and speak to our lord Tibbetti, who is a very simple man, and like a child."

"O Wafa," said one of the group of armed men which stood shivering on the beach in the cold hours of dawn, "may this be a good palaver! As for me, my stomach is filled with fearfulness. Let us all drink this magic water, for it gives us men courage."

"That you shall do when you have carried out all our master's works,"

said Wafa, and added with confidence: "Have no fear, for soon you shall see great wonders."

They heard the deep boom of the _Zaire's_ siren signalling a solitary and venturesome fisherman to quit the narrow fair-way, and presently she came round the bend of the river, a dazzling white craft, showering sparks from her two slender smoke-stacks and leaving behind her twin cornucopias of grey smoke.

Wafa stepped into a canoe, and, seeing that the others were preparing to follow him, he struck out swiftly, man[oe]uvring his ironwood boat to the very waters from whence a scared fisherman was frantically paddling.

"Go not there, foreigner," wailed the Isisi Stabber-of-Waters, "for it is our lord Sandi, and his puc-a-puc has bellowed terribly."

"Die you!" roared Wafa. "On the river bottom your body, son of a fish and father of snakes!"

"O foreign frog!" came the shrill retort. "O poor man with two men's wives! O goatless----"

Wafa was too intent upon his business to heed the rest. He struck the water strongly with his broad paddles, and reached the centre of the channel.

Bones of the Houssas put up his hand and jerked the rope of the siren.

_Whoo-o-o--woo-o-op!_

"Bless his silly old head," said Bones fretfully, "the dashed fellow will be run down!"

The girl was dusting Bones's cabin, and looked round. "What is it?" she asked.

Bones made no reply. He gripped the telegraph handle and rung the engines astern as Yoka, the steersman, spun the wheel.

b.u.mp! b.u.mp! b.u.mpity b.u.mp!

The steamer slowed and stopped, and the girl came out to the bridge in alarm. The _Zaire_ had struck a sandbank, and was stranded high, if not dry.

"Bring that man on board," said the wrathful Bones. And they hauled to his presence Wafa, who was neither Arab nor N'gombi, but combined the vices of both.

"O man," said Bones, glaring at the offender through his eyegla.s.s, "what evil ju-ju sent you to stop my fine ship?" He spoke in the Isisi dialect, and was surprised to be answered in coast Arabic.

"Lord," said the man, unmoved by the wrath of his overlord, "I come to make a great palaver concerning spirits and devils. Lord, I have found a great magic."

Bones grinned, for he had that sense of humour which rises superior to all other emotions. "Then you shall try your magic, my man, and lift this ship to deep water."

Wafa was not at all embarra.s.sed. "Lord, this is a greater magic, for it concerns men, and brings to life the dead. For, lord, in this forest is a wonderful tree. Behold!"

He took from his loose-rolled waistband a piece of wood. Bones took it in his hand. It was the size of a corn cob, and had been newly cut, so that the wood was moist with sap. Bones smelt it. There was a faint odour of resin and camphor. Patricia Hamilton smiled. It was so like Bones to be led astray by side issues.

"Where is the wonder, man, that you should drive my ship upon a sandbank! And who are these?" Bones pointed to six canoes, filled with men, approaching the _Zaire_. The man did not answer, but, taking the wood from Bones's hand, pulled a knife from his belt and whittled a shaving.

"Here, lord," he said, "is my fine magic. With this wood I can do many miracles, such as making sick men strong and the strong weak."

Bones heard the canoes b.u.mp against the side of the boat, but his mind was occupied with curiosity.

"Thus do I make my magic, Tibbetti," droned Wafa.

He held the knife by the haft in the right hand, and the chip of wood in his left. The point of the knife was towards the white man's heart.
