Gerilleau's mind was inclined to run on the unkind things the lieutenant had said in the heat of his last fever.

"He says I murdered 'im," he protested. "It is simply absurd. Someone 'ad to go aboard. Are we to run away from these confounded ants whenever they show up?"

Holroyd said nothing. He was thinking of a disciplined rush of little black shapes across bare sunlit planking.

"It was his place to go," harped Gerilleau. "He died in the execution of his duty. What has he to complain of? Murdered!... But the poor fellow was—what is it?—demented. He was not in his right mind. The poison swelled him... U'm."

They came to a long silence.

"We will sink that canoe—burn it."

"And then?"

The inquiry irritated Gerilleau. His shoulders went up, his hands flew out at right angles from his body. "What is one to do?" he said, his voice going up to an angry squeak.

"Anyhow," he broke out vindictively, "every ant in dat cuberta!—I will burn dem alive!"

Holroyd was not moved to conversation. A distant ululation of howling monkeys filled the sultry night with foreboding sounds, and as the gunboat drew near the black mysterious banks this was reinforced by a depressing clamour of frogs.
