Johnny jumped and went on his toes to a spot where he could look through the foliage.

"Walking down," explained Rosa, and waved a skinny hand toward the hill behind them.

"Did you see him?"

"No, senor. I'm seeing rocks falling where somebody walks down."

There was nothing to do but wait. Johnny pushed the girl toward the cabin and saw her scramble under the lowest branches and join the others unconcernedly, tagging the boy Josef, and, then running off into the open—where she could see the hillside—with Josef running after. She did not seem to be watching the hill, while she was apparently absorbed in dodging Josef, but Johnny gathered from her gestures that the man was still coming and that he was making for the cabin. He was wondering what she meant by suddenly sinking to the ground in shrill laughter, when he heard a step behind him. He whirled, startled, his hand jerking back toward the gun he wore.

"I approve your watchfulness, but you happened to be watching in the wrong direction," said Cliff, brushing dirt from his hunting clothes. "Well, they are getting warm, old man. They have eliminated Riverside as a probable hang-out for the mystery plane, and—" He waved a hand significantly while he stood his shotgun against the bole of the tree.

"Some one saw us land in this valley," he added. "Luckily they do not suspect Mateo yet. I saw him going down the flat and sent him on to tell the patrol a lot they already knew. He saw the plane come down, but has not been able to find the exact spot. He thinks it took the air again. His ninos told him of a big bird flying east. Great boy, Mateo. Great kids. Did they see me coming?"

"Sure they did. Rosa's eagle eye spotted a rock or two rolling down and came and told me."

"Good girl, Rosa. The car's over in another valley, parked under a tree very neatly and permanently and in plain sight. Its owner is off hunting somewhere. By its number plates they will never know it. Good old car."

"You seem tickled to think they're after you," Johnny observed, rolling a cigarette by way of manifesting complete unconcern. "What's the next move?"
