“I don’t know.”
“Which way did they go?”
“That way,” and Brassy pointed out the direction.
By this time the two professors had reached the top of the stairs and Grawson was looking at the water marks on the polished floor.
“Here is where they brought that big snowball in,” he remarked, pointing to the track that led to one of the windows. “They must have brought it up on the fire-escape.”
“Here are several other tracks. I think we had better follow them,” returned Snopper Duke quickly.
The track leading to the bathroom was most in evidence, and the two professors quickly discovered the big snowball resting in the bathtub.
“Evidently they put this here to have some more fun with,” announced Professor Grawson grimly. “Well, it won’t do much harm here. I’ll turn on a little hot water and it will soon melt and run off,” and he turned on the faucet as he spoke.
From the bathroom the two professors, followed by Codfish and Brassy, followed the water trail into a room occupied by several students who were particularly uppish and whom the Rovers did not like, and here some more of the snowballs were found.
“Here is another trail,” announced Professor Duke, and in a moment more had thrown open the door leading to Stowell’s bedroom.
