is face was grim and savage as his own plane sped through the clouds. But just as the two aircraft had approached each other with the combined speed of both, so they separated. It seemed only a moment later that Bell dipped down below the clouds and the other plane was visible only as a swiftly receding mote in the sunlight.

"I wonder," said Bell coldly to himself, with the thunder of the motor coming through the singing of the air route signal, "I wonder if he'll see the ship I cracked up last night?"

Paula was pointing. The shoulder of a hill upthrust beneath the jungle. The tall trees were cleared away at its crest. Small, whitewashed buildings appeared below.

"Good landing field," said Bell, his eyes narrowing suddenly. "On the direct route. Fifty miles back there's another landing field. I wonder...."

He was already suspicious before he flattened out above the house, while dogs fled madly. He noticed, too, that horses in a corral near the buildings showed no signs of fright. And horses are always afraid of landing aircraft, unless they have had much opportunity to grow accustomed to them.

The little plane rolled and bumped, and gradually came to a stop. Bell inconspicuously shifted a revolver to the outer pocket of his flying suit. Figures came toward them, with a certain hesitating reluctance that changed Bell's suspicions even while it confirmed them.
