He had had his own flashlight with him and had not had to turn up the lights in the dormitory, a proceeding that might have caused attention, and he was sure that no one had seen him at work, and indeed no one had.
When the boys went up to bed, Jack, still occupying the same dormitory as at first, Billy was ready to see the result of his little joke, but said nothing to any of the boys about it.
“Will you change beds with me to-night, Billy?” presently asked Jack, taking off his coat and hanging it on a hook. “Mine is a little too warm, but you don’t mind that.”
“Now I wonder if he has got onto it?” thought Billy. “He could not have been up here since.”
“It will only be for to-night,” Jack added.
“What’s the use of changing?” asked Billy. “I don’t like too warm a bed myself.”
“Oh, this isn’t too warm, just warm enough for you,” laughed Jack.
“He has got onto something,” thought Billy, “and wants to see me go down. Not much, I won’t.”
“Why can’t you be obliging, Billy?” asked Arthur. “I’m sure I’d do a little thing like that if I was asked.”
“I wonder if they are both in it?” thought the young joker.
