"I don't like it, Jack. We're on top this time, thanks to a little bluff. But there must have been a large number of them to judge by the canoes and the yells; and but for that fellow Nando we might easily have been wiped out. And from what Nando says they are those villainous forest guards of the Concession. What's the meaning of it? It may be that the Concession have repented of their bargain and want to keep me out, or perhaps Elbel is terrified lest I shall expose him when I get back to Boma. Either way, it seems as if we're going to have a bad time of it."

"I don't think it can be Elbel's doing, uncle. It's such a risky game to play, your expedition being authorized by his own people."

"I don't imagine Elbel is such a fool as to attack us officially. He can always disavow the actions of those natives. At any rate, I shall make a point of getting rifles for the men as soon as I can."

"They can't use them."

"Of course they can't; but you'll have to turn yourself into a musketry instructor. Meanwhile I must give that fellow Nando some sort of reward. It will encourage him and the others too."

When daylight broke Mr. Martindale went down to the river while Barney was preparing breakfast. There was no trace of the enemy. Presumably they had set their canoes afloat and drifted down stream in the darkness. They had no doubt reckoned on surprising the camp, and their calculations had been upset by the certainty of meeting with resistance, the fact that the travellers were poorly armed being forgotten in the panic bred of the sudden uproar in the night.

After breakfast Mr. Martindale had the men paraded in a semicircle around the tent, and, sitting on a stool in front of it, with Jack on one side and Barney on the other, he called Nando forward.

"We are very much pleased with your watchfulness, Nando."

The negro grinned, and with a ludicrous air of importance translated the sentence to his comrades.

"It is due to you that we were not surprised in the dark: you did very well, and set an excellent example to the men."
