"Rats! this won't do!" he finally exclaimed, and shaking himself, he hurried out of the building and on to the broad, velvety college campus.

Students were walking in various directions, going to, or coming from, classes and lectures. Many hailed him and he called out in return, or waved his hand. The Rover boys had a host of friends at Brill.

Presently Tom saw a tall, slim young man coming up, dressed in a light, checked suit, and wearing pointed patent-leather ties and a rose-colored cap. In the buttonhole of the student was a large carnation. Under his arm the approaching one carried half a dozen text books.

The face of the fun-loving Rover lighted up and for the time being the pain in his head was forgotten. His hand went down in a pocket, to feel for something, and then came forth again. Then he stepped forward and crooked out his elbow.

The other student was looking to one side as he came forward and he did not notice the elbow in his way. The elbow caught him in the ribs, causing him to give a grunt, and the armful of books were scattered on the walk.

"My gracious me!" gasped the stylishly-dressed youth. "What did you do that for, Tom Rover?"

"Sorry, Tubblets," answered Tom, making as sober a face as possible. "I didn't know you wanted the whole walk."

"You did that on purpose, Tom Rover, you know you did!"

"Did what on purpose, Tubby?"

"How many times must I tell you that my name is not Tubby or Tubblets. It is William Philander Tubbs, and I want you to call me by my right name after this."
