“And—er—romantic,” he suggested slyly.

She did not answer, and turned away; but Sheldon knew that the shaft had gone home.

“That fella boy he sick, belly belong him walk about,” Binu Charley said, pointing to the Poonga-Poonga man whose shoulder had been scratched by the arrow an hour before.

The boy was sitting down and groaning, his arms clasping his bent knees, his head drooped forward and rolling painfully back and forth. For fear of poison, Sheldon had immediately scarified the wound and injected permanganate of potash; but in spite of the precaution the shoulder was swelling rapidly.

“We’ll take him on to where Tudor is lying,” Joan said. “The walking will help to keep up his circulation and scatter the poison. Adamu Adam, you take hold that boy. Maybe he will want to sleep. Shake him up. If he sleep he die.”

The advance was more rapid now, for Binu Charley placed the captive bushman in front of him and made him clear the run-way of traps. Once, at a sharp turn where a man’s shoulder would unavoidably brush against a screen of leaves, the bushman displayed great caution as he spread the leaves aside and exposed the head of a sharp-pointed spear, so set that the casual passer-by would receive at the least a nasty scratch.

“My word,” said Binu Charley, “that fella spear allee same devil-devil.”

He took the spear and was examining it when suddenly he made as if to stick it into the bushman. It was a bit of simulated playfulness, but the bushman sprang back in evident fright. Poisoned the weapon was beyond any doubt, and thereafter Binu Charley carried it threateningly at the prisoner’s back.

The sun, sinking behind a lofty western peak, brought on an early but lingering twilight, and the expedition plodded on through the evil forest—the place of mystery and fear, of death swift and silent and horrible, of brutish appetite and degraded instinct, of human life that still wallowed in the primeval slime, of savagery degenerate and abysmal. No slightest breezes blew in the gloomy silence, and the air was stale and humid and suffocating. The sweat poured unceasingly from their bodies, and in their nostrils was the heavy smell of rotting vegetation and of black earth that was a-crawl with fecund life.

They turned aside from the run-way at a place indicated by Binu Charley, and, sometimes crawling on hands and knees through the damp black muck, at other times creeping and climbing through the tangled undergrowth a dozen feet from the ground, they came to an immense banyan tree, half an acre in extent, that made in the innermost heart of the jungle a denser jungle of its own. From out of its black depths came the voice of a man singing in a cracked, eerie voice.
