“He can’t stop a certified check, Sam.  I’ll put it in the school safe for the present.  What we want to do is to look after the Dartaway.  She may not be worth much, but what there is of her belongs to us.”

“Right you are.  Let us get permission to go after her right away.  For all we know, somebody may have carted her off already!”

The boys readily obtained permission to see to their property, and walked down to the college stables to get a horse and carriage to take them to the spot where the accident had occurred.  Just then came a toot of an automobile horn, and a fine five-passenger car rolled into view, with Stanley Browne and a stranger on the front seats.

“Hello, you fellows!” cried Stanley, as the auto came to a stop.  “Come over here!  I hoped I’d see you!”

The Rovers hurried across the campus and were introduced to Jack Mason, Stanley’s cousin, the driver of the car.  He was passing through Ashton on the way to join his folks in the White Mountains.

“Jack wants me to take a ride with him this afternoon,” said Stanley.  “And I can invite three others to go along.  Will you come with us?”

“That is kind,” answered Dick.  “But we have some business to attend to,” and he related what it was.

“Say, let’s take a look at the wrecked biplane!” cried Jack Mason.  “I’d just as soon go there as anywhere.”

“So would I,” added Stanley.

“Very well—­ that will suit us down to the ground!” cried Tom.

“We were going to drive over in a carriage,” explained Dick.  “We can get there much quicker in the auto.”

The boys piled into the tonneau of the car and they started off.

“Got to show me the roads,” said Jack Mason.  “All I know around here is the regular auto road to the White Mountains,—­ and I don’t know that any too well.”

“You can’t lose us on the roads!” cried Tom.  “We’ll keep you straight.”

Jack Mason loved to run fast and soon they were bowling along at a forty-mile-an-hour rate.  Stanley and Tom told the driver what turns to make, and almost before they knew it they had passed the outskirts of Ashton and were approaching the locality where the fast Express had dashed into the crippled biplane.

“Here we are!” cried Tom, presently.  “We 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?”
