"Nothing on it," announced Roger, after an inspection. "Maybe the box was placed in this room by mistake."
"Let us open it and see what is inside," suggested Polly Vane.
"I second that motion," added Luke. "Hope it's got some nice Christmas pies in it."
"Maybe it's a trick," cautioned Shadow. "Go slow on opening it."
The boys pushed the box to the center of the dormitory with care, and then Roger cut the cord with his pocketknife.
"You open it," said Phil to Dave.
"I am not afraid," answered Dave, and took off the cover.
And then what a shout went up!
"Our shoes, and boots, and slippers!"
"Where in the world did this come from!"
"Say, I thought my shoes were gone for good!"
"Are they all here?"
"I guess so. Let us sort 'em out and see."
Hastily the box was turned over, and the contents dumped on the floor. Then began a general sorting out, lasting for several minutes.
"One of my gym. shoes is missing," announced Phil.
"Perhaps one of the other fellows has it," suggested Dave, and the shipowner's son started a fresh search. But it was of no avail. Every shoe, slipper, and boot that had been taken had been returned excepting one of Phil's foot coverings.
"Well, I don't care much," said Phil. "These shoes were about worn out, anyway."
"Where do you suppose this box came from?" asked Ben, and then he gazed curiously at Shadow, and the others did the same.
"I – I suppose you think – that is, you imagine I – er – I had something to do with this," stammered the boy who had on several occasions walked in his sleep.
"Do you know anything about it, Shadow?" asked Dave.
"Not the first thing!"
"Did you dream of anything last night?"
"Yes, I dreamed about a – er – a – " stammered the sleep-walker. "I – er – Oh, it wasn't about shoes, or anything like that."
"Well, what was it?" demanded Roger, sternly.
"It was about a party, if you must know. I dreamt I took a girl, and we had a nice time dancing and playing games. There weren't any shoes in it," and poor Shadow got redder than ever.
Dave looked the box over with care. It was a common pasteboard box, with nothing on it in the way of writing or advertising.
"This certainly is a mystery," he said, slowly. "First the shoes disappear, and now they come back. I give it up."
"Somebody has been playing a trick on us!" declared Roger. "The question is, who?"
"I don't know of anybody who would do such a thing, excepting it was Nat Poole," declared Ben.
"Well, there is no use of taxing Nat with it," declared Dave. "For he would deny it point-blank, unless you could prove it against him."
The boys talked the affair over until it was time to go down to breakfast, but they could reach no conclusion regarding the mystery.
"Maybe it will never be explained," said Buster.
"Well, even so, I am glad to get my shoes and slippers back," lisped Polly Vane.
A few days after the restoration of the foot coverings there came a thaw and then a sudden cold snap. Ice began to form on the river, and soon it was thick enough for skating, much to the joy of the students, for nearly all of them loved to skate. Some of the boys had ice-boats, and these were also brought out for use.
"I understand that Rockville is going to put out a strong ice-hockey team this winter," said Roger to Dave one day. "They are going to challenge us, too."
"Well, we'll have to make up a team to beat 'em," answered Dave.
"That won't be so easy," declared another student. "They have some great skaters and hockey players at the military academy this season. They've got one player who is a star."
"Who is that?"
"Will Mallory. He came from down East, and he is the slickest ice-hockey player you ever set eyes on."
"Well, if they challenge us we'll do our best," declared Dave, and some others said the same.
The next day, after school, Dave had occasion to go to Oakdale on an errand. Roger was going along, but at the last minute had to stay behind, so Dave went alone.
He had scarcely passed out of the school grounds when he noticed that he was being followed. A tall, thin man had stepped from behind some oak trees, and was coming after him.
"I wonder what that chap was doing around the school?" the youth asked himself.
He walked along rapidly, and the man did the same. Then Dave slackened his pace, and the follower did likewise.
"He doesn't want to catch up to me, that's sure," thought the youth. "Maybe he is afraid I'll recognize him. Wonder who he is?"
He turned and looked back. But the man had his overcoat pulled up and his soft hat pulled far down, and Dave could see little of his face.
"This is a mystery," mused Dave. "I am going to speak to him," and he stopped short and waited for the mysterious individual to come up.
CHAPTER XXIII
HOOKER MONTGOMERY'S STRANGE REQUEST
The stranger approached slowly, as if hoping Dave would go on before he came up. Once he looked towards the fields on either side of the road, as if thinking to turn off. But no side road was at hand, so he had to either come on or turn back.
