"Watch sharp, Towahg!" Chet ordered. And, to the others: "Get this fire moved away from the huts--here. I'll do that, Walt. You bring a supply of wood; some of those dried leaves, too. We'll build a big fire, we have to depend on that for light." * * * * * With the skeleton of a huge palm leaf he raked the fire out into an open space; they had plenty of fuel and they fed the blaze until its mounting flames lighted the entire enclosure. But outside the barricade were dark shadows, and Chet saw that this light would only make targets of the defenders, while the attackers could creep up in safety. "'Way up," he ordered; "we've got to have the fire on the top of the rocks." He clambered to the topmost level of the rocky outcrop and dragged a blazing stick with him. Harkness handed him more; and now the light struck down and over the stockade and illumined the ground outside. "Here's your job, Kreiss," said Chet, "if you're equal to it. You keep that fire going and have a pile of dried husks handy if I call for a bright blaze. "We've got to defend the whole works," he explained. "That bunch today tried to jump us just from one side, but trust Schwartzmann to divide his force and hit us from all sides next time. "But we'll hold the fort," he said and he forced a confidence into his voice that his inner thoughts did not warrant. To Harkness he whispered when Diane was away: "Six shells in the gun, Walt; we won't waste them on the apes. There's one for each of us including Towahg, and one extra in case you miss. We'll fight as long as we are able; then it's up to you to shoot quick and straight." But Walt Harkness felt for the pistol in his belt and handed it to Chet. "I couldn't," he said, and his voice was harsh and strained, "--not Diane; you'll have to, Chet." And Chet Bullard dropped his own useless pistol to the ground while he slipped the other into its holster on the belt that bound his ragged clothes about him, but he said nothing. He was facing a situation where words were hardly adequate to express the surging emotion within. * * * * * Diane had returned when he addressed Walt casually. "Wonder why the beggars didn't attack again," he pondered. "Why has Schwartzmann waited; why hasn't he or one of his men crept up in the grass for a shot at us? He's got some deviltry brewing." "Waiting for night," hazarded Walt. He looked up to see Kreiss who had joined them. "If Towahg could tend the fire," suggested the scientist, "I could fire my little catapult with one hand. I think I could do some damage." But Chet shook his head and answered gently: "I'm afraid Towahg's the better man to-night, Kreiss. You can help best by giving us light. That's the province of science, you know," he added, and grinned up at the anxious man.
