“Dave, Elmer,” he shouted—“look there!”
“It’s number seven, sure as you live!” echoed Elmer, excitedly.
“I think so, too,” agreed their pilot more quietly, but all his senses were on the keenest alert.
Over beyond a high ridge all hands saw distinctly an airship. Its outline answered to the description of number seven. The way it sailed told that it was an expert racer and under the control of a true professional.
It was lost to view behind a tree-capped ridge. When the Comet in its course has got past this obstruction, the airship had disappeared.
“It’s gone, but where?” called out Hiram.
“There it is,” suddenly cried Elmer.
About three miles ahead of them was a little settlement. This side of it a fenced-in farm showed. In the center of its barnyard the airship boys saw the machine that had been sailing aloft a short time previous.
Apparently it had descended on account of some break or accident. There seemed to be no valid reason why it should land at a remote farmhouse.
“Why, there’s trouble,” exclaimed Hiram.
