At dawn, they were marching again, stepping more briskly over tiny creeks, through green-tinted mud, and the wet heat. At noon, they heard the horn again, and Clark ordered silence and a faster pace. They swung swiftly, eating iron rations as they marched. Hague leaned into his cart harness and watched perspiration staining through Bormann's shirted back just ahead of him. Behind, Sergeant Brian tugged manfully, and growled under his breath at buzzing insects, slapping occasionally with a low howl of muted anguish. Helen, the skin bird, rode on Bormann's shoulder, staring back into Hague's face with questioning chirps; and Hague was whistling softly between his teeth at her, when Bormann stopped suddenly and Hague slammed into him. Helen took flight with a startled squawk, and Clark came loping back to demand quiet. Bormann stared at the two officers, his young-old face blank with surprise.

"I'm, I'm shot," he stuttered, and stared wonderingly at the thing thrusting from the side opening in his chest armor. It was one of the fragile bronze arrows, gleaming metallically in the forest gloom.

Hague cursed, and jerked free of the cart harness.

"Here, I'll get it free." He tugged at the shaft, and Bormann's face twisted. Hague stepped back. "Where's Sewell? This thing must be barbed."

"Back off the trail! Form a wide circle around the cart, but stay under cover! Fight 'em on their own ground!" Clark was yelling, and the men clustered about the cart faded into forest corridors.

Hague and Sewell, left alone, dragged Bormann's limp length beneath the metal cart. Hague leaped erect again, man-handled the pneumatic gun off the cart and onto the trail, spun the charger crank, and lay down in firing position. Behind him, Sewell grunted, "He's gone. Arrow poison must have paralyzed his diaphragm and chest muscles."

"Okay. Get up here and handle the ammunition." Hague's face was savage as the medical technician crawled into position beside him and opened an ammunition carrier.

"Watch the trail behind me," Hague continued, slamming up the top cover plate and jerking a belt through the pneumatic breech. "When I yell charge, spin the charger crank; and when I yell off a number, set the meter arrow at that number." He snapped the cover plate shut and locked it.

"The other way! They're coming the other way!" Sewell lumbered to his knees, and the two heaved the gun around. A blowgun arrow rattled off the cart body above them, and gobbling yells filtered among the trees with an answering crack of explosive cartridges. A screaming knot of grey figures came sprinting down on the cart. Hague squeezed the pneumatic's trigger, the gun coughed, and blue-fire-limned lizard-men crumpled in the trail mud.

"Okay, give 'em a few the other way."
