But the first wave was spent. There were no more snarling, white-toothed faces above the barricade, and in the open space beyond were shambling forms that hid themselves in the long grass while others dragged themselves to the same concealment or lay limply inert on the open, sunlit ground. And within the enclosure one solitary ape-man forgot his bruised body while he stamped up and down or whirled absurdly in a dance that expressed his joy in victory. "Better come down," said Chet. "Schwartzmann might take a shot at you, although I think we are out of pistol range. We're lucky that isn't a service gun he's got, but come down anyway, and we'll see what's next. This time we've had the breaks, but there's more coming. Schwartzmann isn't through." But Schwartzmann was through for the day; Chet was mistaken in expecting a second assault so soon. He posted Towahg as sentry, and, with Diane and Harkness, threw himself before the door-flap of the shelter where Kreiss had been hidden, and was now sitting up, his arm in a sling. "Either you're a 'mighty hard man to kill,'" he told Kreiss, "or else Towahg is a powerful medicine man." "I am still in the fight," the scientist assured him. "I can't do any more work with bow and arrow, but I can keep the rest of you supplied." "We'll need you," Chet assured him grimly. * * * * * They ate in silence as the afternoon drew on toward evening. Back by their little fire, with Towahg on guard, Chet shot an appreciative glance at a white disk in the southern sky. "Still getting the breaks," he exulted. "The moon is up; it will give us some light after sunset, and later the Earth will rise and light things up around here in good shape." That white disk turned golden as the sun vanished where mountainous clouds loomed blackly far across the jungle-clad hills. Then the quick night blanketed everything, and the golden moon made black the fringe of forest trees while it sent long lines of light through their waving, sinuous branches, to cast moving shadows that seemed strangely alive on the open ground. Muffled by the jungle-sea that absorbed the sound waves, faint grumblings came to them, and at a quiver of light in the blackness where the clouds had been, Harkness turned to Chet. "We had all better get on the job," Chet was saying, as he took his bow and a supply of arrows, "we've got our work cut out for us to-night." And Harkness nodded grimly as the flickering lightning played fitfully over far-distant trees. "We crowed a bit too soon," he told Chet; "there's a big storm coming, and that's a break for Schwartzmann. No light from either moon or Earth to-night." The moon-disk, as he spoke, lost its first clear brilliance in the haze of the expanding clouds.
