"I hope we'll have some clothes on when it comes off, then," growled Ned.
"It won't make much difference whether you have or not, so far as this invitation is concerned."
"What is the invitation?" asked Professor Zepplin.
"Bud Thomas and the other cowboys are hunting wild horses for market, you know?" replied the guide.
"Wild horses?" marveled Walter.
"Yes."
"I didn't know there were any about here," said Tad.
"It is estimated that there are all of a hundred thousand wild horses in the different ranges of this state," replied the guide.
"You haven't told us yet what the invitation is," reminded Stacy.
"You haven't given me a chance," laughed Tom. "Well, the invitation is to join in a wild horse hunt."
