smaller clumps of what could only be animals gathered together. Cattle. But here the girl was plainly in view. Calhoun increased his stride. He began to gain on her. She did not look behind. Murgatroyd said "Chee!" in a complaining tone. "I should have left you behind," agreed Calhoun dourly, "but there was and is a chance I won't get back. You'll have to keep on hiking." He plodded on. His memory of the terrain around the mining settlement told him that there was no definite destina[46]tion in the girl's mind. But she was in no such despair as to want deliberately to be lost. She'd guessed, Calhoun believed, that if there were Darians on the planet, they'd keep the landing-grid under observation. [46] If they saw her leave that area and could see that she was alone, they should intercept her to find out the meaning of the Med Ship's landing. Then she could identify herself as one of them and give them the terribly necessary warning of Weald's suspicions. "But," said Calhoun sourly, "if she's right, they'll have seen me marching after her now, which spoils her scheme. And I'd like to help it, but the way she's going is too dangerous!" He went down into one of the hollows of the uneven plain. He saw a clump of a dozen or so cattle a little distance away. The bull looked up and snorted. The cows regarded him truculently. Their air was not one of bovine tranquility. He was up the farther hillside and out of sight before the bull worked himself up to a charge. Then Calhoun suddenly remembered one of the items in the data about cattle he'd looked into just the other day. He felt himself grow pale. "Murgatroyd!" he said sharply. "We've got to catch up! Fast! Stay with me if you can, but—" he was jog-trotting as he spoke—"even if you get lost I have to hurry!" He ran fifty paces and walked fifty paces. He ran fifty and walked fifty. He saw her, atop a rolling of the ground. She came to a full stop. He ran. He saw her turn to retrace her steps. He flung off the safety of the blast-rifle and let off a roaring blast at the ground for her to hear. Suddenly she was fleeing desperately, toward him. He plunged on. She vanished down into a hollow. Horns appeared over the hillcrest she'd just left.
