With his flashlight flicking the dots and dashes of the Morse code to Sandy, Dick spelt out a message explaining his idea. Twice he flashed the message, got an O. K. from Sandy, and told Larry.

There were some preparations on the other skycraft, then Larry dropped the nose of his plane and went down a few feet. The amphibian flew over them, high enough so its hanging pontoons would not scrape their craft, and as the cockpits were low, it could drop fairly close.

Sandy leaned out, a doughnut of white came shaking and swinging at the end of a rope. Dick braced himself, safety belt snapped tight, arms extended upward. Larry held his ship at flying speed and level. Once an air shift dipped the amphibian dangerously low, but Larry saw it coming and dived ten feet, then leveled again. Once more they tried to jockey into position.

Dick saw the doughnut swing toward him, threw his head back to avoid the blow, but it struck his chest. With a grunt, his arms closed and he clung. Sandy, feeling the tug of the rope, let go.

Dick dragged in the rope to prevent it from flying back into the empennage, fouling the tail assembly—and they had the preserver.

Then Dick shouted a warning. Larry dived. Tommy was coming at them.

CHAPTER XXXIV
THE EMERALDS ARE FOUND

Larry sent his craft into a sharp dive. Tommy, trying to prevent the maneuver, came straight toward the spot they had occupied, but missed.

Now the clouds hid them. By use of his instruments he could keep on a level keel, Larry knew, and with the engine throttled off, they could not be traced by its roar.

Presently they sailed out into a clear area and Larry sighed thankfully. He watched for a landing field beside a lake shaped like a half-moon. That would tell him he could set down on the landing spot the millionaire had built before going West.
