"This is certainly a mystery!" came from Link, and he followed Harry to the dressing-room, and so did Matt. They found Joe and Harry getting into their uniforms with all possible speed.
"What in the name of goodness——" began Harry, when Joe stopped him short.
"Don't say anything now, Harry. Si Voup is responsible for it. I'll explain later. Are all the other fellows here?"
"Yes, but——"
"Si had us kidnapped. He doesn't know we are here. Fred and I want to surprise him."
"Oh! Well——"
"Tell the other fellows to take their old positions. After you are in position give a loud whistle and Fred and I will come out," went on Joe.
His brother and the others understood, and left the dressing-room as quickly as they had entered it.
In the meantime Si Voup, Boardman and the others of the Excelsiors were talking earnestly among themselves.
"We are going to have a walkover," said Voup.
