can't go any further on the road. We'll have to walk through the woods to the tracks."
"I see a wood road!" exclaimed Jack Mason. "If the ground isn't too soft I'll try that."
He went on and passed in between the trees, and soon they were within a hundred feet of the railroad tracks. As the car came to a stop the Rover boys jumped to the ground and ran forward. Then, of a sudden, all three set up a shout:
"The biplane is gone!"
"Gone?" queried Stanley, who was close behind them.
"Yes, gone," returned Tom.
"Are you sure this is the spot where it was struck?"
"Of course I am."
"There are the marks where we landed and where the locomotive hit the Dartaway," said Sam. He looked around. "Wonder who took her, and to where?"
"That's to be found out," answered Dick, seriously.
"I don't see any airship," said Jack Mason, as he came up, having shut off the engine of the touring car.
"Somebody has hauled it away," answered Dick. He looked on both sides of the track.
