ying bee all right!" cried Tom.

"Well, wouldn't you like it yourself?" demanded the youngest Rover.

"I'd rather have a big airship. Then I could give all my friends a
ride--have a regular airship party."

"Well, I'd like that too," was Sam's reply.

Presently they came in sight of the seminary buildings. They circled
around for some time and then landed at the far end of the campus. A few
girls were in sight, but not those they had come to visit.

"Good afternoon," said Dick, to a girl he had met, named Ida Strong.
"Can you tell me where I can find Miss Stanhope, or the Misses Laning?"

"The three of them went for a walk, about half an hour ago," replied Ida
Strong.

"Do you know where they went?"

"I do not, excepting that they took the road to Beechwood," and the girl
student pointed out the highway mentioned, one that ran through the big
woods back of the seminary. It led to the village of Beechwood, which
was several miles beyond.

"Thank you," returned Dick. "If we shouldn't meet them, will you tell
them we called, in our biplane?"

"I will," said the girl.

Dick was about to rejoin his brothers, and suggest that they go up and
fly along over the woods road, when another girl, named Bess Haven, came

"Oh, Mr. Rover, isn't this queer!" she cried. "I thought you were hurt!"

"Hurt?" repeated Dick, puzzled. "How so?"

"Why Dora Stanhope said you were--that you had had a fall out of the
flying machine."

"About half an hour ago. She got some sort of a message, and she was
terribly upset. She went off to visit you."

"Where to?"

"I don't know. But wait--yes, she did say you had had a fall in the
woods."

"Did she go alone?" And now Dick's heart began to thump strangely. He
was thinking of their many enemies. Was this some new trick?

"No, Nellie and Grace Laning, her cousins, went with her."

Dick turned to Ida Strong.

"You saw them go?"

"Yes, just as I told you. Oh, Mr. Rover, is anything wrong?"

"I don't know--I hope not. But I think we had better go after them at
once. Good day." And Dick fairly ran back to where Tom and Sam rested
near the biplane.

"Start her up, quick!" he said to his brothers, in a low voice.
"Something is wrong! We've got to get after the girls right away!"

"What is it?" demanded Tom, leaping to his feet, while Sam did t
