"Yes, I wonder what he's hanging around here for?"
They learned a moment later, for they saw Pete going into the telegraph office.
"Must be something important for him to wire about," observed Ned.
Tom did not answer. The window of the office was slightly open, though the day was cool, and he was listening to the clicks of the telegraph instrument, as the operator sent Pete's message. Tom was familiar with the Morse code. What was his surprise to hear the message being sent to Andy Foger at a certain hotel in Chicago. And the message read:
"Tom Swift's party leaving to-day."
"What in the world does that mean?" thought Tom, but he did not tell Ned what he had picked up as it went over the wire. "Why should Andy want to be informed when we leave? That's why Pete was hanging around here! He had been instructed to let Andy know when we left for Seattle. There's something queer back of all this."
Tom was still puzzling over the matter when their train roiled in and he and the others got aboard.
"Well, we're off!" cried Ned.
"Yes; we're off," admitted Tom, and, to himself he added: "No telling what will happen before we get there, though."
The trip to Chicago was without incident, and, on arrival in the Windy City, Tom was on the lookout for Andy or his father, but he did not see them. He made private inquiries at the hotel mentioned in Pete's telegram, but learned that the Fogers had gone on.
