The Apaches settled back in the cup, which gave them a wide view over the plains. Soon it was not necessary to use the glasses in order to sight the advancing party of hunters—five riders, four wearing Tatar dress. The fifth had such an odd outline that Travis was reminded of Menlik's sketch of the alien. Under the sharper vision of the glasses he saw that the rider was equipped with a pack strapped between his shoulders and a bulbous helmet covering most of his head. Highly specialized equipment for communication, Travis guessed.

"That is a 'copter up above," Nolan said. "Different shape from ours."

They had been familiar with helicopters back on Terra. Ranchers used them for range inspection, and all of the Apache volunteers had flown in them. But Nolan was correct; this one possessed several unfamiliar features.

"The Tatars say they don't bring those very far into the mountains," Jil-Lee mused. "That could explain their man on horseback; he gets in where they don't fly."

Nolan fingered his bow. "If these Reds depend upon their machine to control what they seek, then they may be taken by surprise——"

"But not yet!" Travis spoke sharply. Nolan frowned at him.

Jil-Lee chuckled. "The way is not so dark for us, younger brother, that we need your torch held for our feet!"

Travis swallowed back any retort, accepting the fairness of that rebuke. He had no right to believe that he alone knew the best way of handling the enemy. Biting on the sourness of that realization, he lay quietly with the others, watching the riders enter the foothills perhaps a quarter of a mile to the west.

The helicopter was circling now over the men riding into a cut between two rises. When they were lost to view, the pilot made wider casts, and Travis thought the flyer's crew were probably in communication with the helmeted one of the quintet on the ground.

He stirred. "They are heading for the Tatar camp, just as if they know exactly where it is—"
