"You see, monsieur, we are well provided. A machine gun, you will admit, is even more useful within walls than without. Now as to your position. You have under your command some three hundred men trained—more or less. Whether as a military force they are better than our men can only be decided if unfortunately you determine to put the matter to the test. But consider your risks. Two days ago we captured your stores."—The officer jumped.—"Your rearguard is in our hands, and that was your machine gun."—The officer stared.—"You are at least three weeks from your base, with perhaps two days' provisions in hand, no reserve of ammunition, and, as I said, the rains overdue. Yonder country, during the rains, is a swamp."

Lieutenant Jennaert turned pale. His messengers sent back to hurry on the dilatory convoy had strangely failed to return. But recovering himself, with a feeble attempt to smile he said—

"You are joking, monsieur. You permit yourself a ruse. Ah! ah! I am not to be entrapped in that way."

"Pardon me, monsieur. You shall have the fullest assurance as to the truth of what I am saying. Lepoko, ask Mr. Barney to send out the white officer."

The Belgian was now looking very uncomfortable. This was a strange turning of the tables; his summons to surrender had been completely forgotten. Jack had no need to kill time by keeping up the conversation, for in a minute or two the lieutenant captured in the river left the fort under an armed guard and walked quickly down.

"Beuzemaker!" exclaimed Lieutenant Jennaert under his breath.

"Yes, monsieur—Monsieur Beuzemaker."

Lieutenant Beuzemaker smiled ruefully as he joined the group. He gave a rapid narrative of the capture of the convoy.

"It only remains, therefore," said Jack, "for you to decide upon your course, monsieur. May I make you a proposal? You shall surrender your arms and ammunition except a dozen rifles. I will supply you with canoes to take your men down the river, and provisions for a fortnight. Within ten days you should enter a district where more food can be obtained. As you know, the country hereabouts has been made almost a desert by your people."

But this was too much. Was it he, Lieutenant Jennaert, who was being called upon to surrender? He rose in a fury.
