shirt and shook him fiercely. "There'll be a gun at your head every minute, and don't you forget. You do anything wrong, and you're dead." Price forebore to explain what would happen to Burr and Twist if they shot him in mid-air. He only nodded and said, "Don't worry. I'm as anxious to get to your Chief as you are." He took a deep breath and plunged. "That's what I came for." Burr said, "You're a long way out of your way." "This is new country to me. I got lost." You don't know how lost. You don't know how alone."Come on," said Twist. "There's been too much yattering already." He led the way back to the edge of the trees. Price and Burr followed him. The others were already working on the carcass. Presently they were hidden from sight. At the verge of the prairies the three men stopped and examined the visible world before they left cover. Price looked around and did not see anything and was ready to go on. Burr and Twist not only looked at earth and sky, they sniffed the wind and seemed to _feel_ the quality of the air, like animals. Twist gave a kind of shrug and said, "Well, we're in it now, whole hog." He began to run through the long grass toward the plane. Burr went fleetly after him. Price, oppressed with many things of which physical exhaustion was the least, ran heavily behind them. When they were within perhaps fifteen feet of the plane a glittering thing came over the tops of the trees and hesitated, making a couple of short spirals in the air. Then it centered over the plane and hung there, high above. It was a disc-shaped object maybe three feet across, with a big lens on its underside. Twist and Burr had stopped. Price came panting up to them. They were looking up at the disc, and Price saw in their faces a wild mingling of rage and hate and the despairing fear of men faced with an enemy that no amount of bravery or physical strength can prevail against. "What is it?" he asked, and Twist said hoarsely, "You must be from a long way west if you've never seen a flying-eye." His hands dropped to his sides. "Well. That's finished." Burr began to curse at the thing. He looked as if he wanted to cry. "What will it do?" asked Price.
