"That's what I want to find out," returned Dick. "That is, provided they came from here,"

They left the car at the entrance to the grounds, and the chauffeur at once turned around and started back for Ashton.

"We'll take a look around the gymnasium first," said Dick. "That is where they keep the bicycles and such things."

They hurried in the direction of the gymnasium, and finding the door unlocked, entered. The building was dark and deserted, for it was now after eleven o'clock.

"Hello there!" called a voice from a distance, and a watchman appeared, lantern in hand. "What's wanted?"

"We want to look at the bicycles, Pinkey," answered Dick.

"The bicycles? Ain't goin' for no ride this time o' night, are you?" asked the watchman.

"No. We want to see if any of them have been used."

"Think somebody has been usin' your machine on the sly?"

To this question the Rovers did not reply, for the reason that they had no bicycles at Brill. The watchman led the way to the bicycle room. Here were about twenty bicycles and half a dozen motor cycles, all belonging to various students.
