Kraski laughed and turned away to resume the march in the direction he had chosen. “You fellows go on your own way if you want to,” he said, “and while you’re traveling, just ponder the fact that you’re south of the equator and that therefore the sun is always in the north, which, however, doesn’t change its old-fashioned habit of setting in the west.”

Bluber was the first to grasp the truth of Kraski’s statement. “Come on, boys,” he said, “Carl vas right,” and he turned and followed the Russian.

Peebles stood scratching his head, entirely baffled by the puzzling problem, which Throck, also, was pondering deeply. Presently the latter turned after Bluber and Kraski. “Come on, John,” he said to Peebles, “hi don’t hunderstand it, but hi guess they’re right. They are headin’ right toward where the sun set last night, and that sure must be west.”

His theory tottering, Peebles followed Throck, though he remained unconvinced.

The four men, hungry and footsore, had dragged their weary way along the jungle trail toward the west for several hours in vain search for game. Unschooled in jungle craft they blundered on. There might have been on every hand fierce carnivore or savage warriors, but so dull are the perceptive faculties of civilized man, the most blatant foe might have stalked them unperceived.

And so it was that shortly after noon, as they were crossing a small clearing, the zip of an arrow that barely missed Bluber’s head, brought them to a sudden, terrified halt. With a shrill scream of terror the Jew crumpled to the ground. Kraski threw his rifle to his shoulder and fired.

“There!” he cried, “behind those bushes,” and then another arrow, from another direction, pierced his forearm. Peebles and Throck, beefy and cumbersome, got into action with less celerity than the Russian, but, like him, they showed no indication of fear.

“Down,” cried Kraski, suiting the action to the word. “Lie down and let them have it.”

Scarcely had the three men dropped among the long grass when a score of pigmy hunters came into the open, and a volley of arrows whizzed above the prone men, while from a nearby tree two steel-gray eyes looked down upon the ambush.

Bluber lay upon his belly with his face buried in his arms, his useless rifle lying at his side, but Kraski, Peebles, and Throck, fighting for their lives, pumped lead into the band of yelling pigmies.
