“There’s an old house out on the Boston road,” said Ben, “that the owner keeps up as a sort of a museum. He has all the old furniture that was used in colonial days. There’s a great deal of travel on that road in summer, and he charges a quarter for every person that goes over the house. There’s a care-taker, of course. I think she serves tea for a quarter extra.”

“That’s an idea,” said Tuckerman. “Only my house isn’t on a main road. It’s a rather hard place to reach.”

“All the better,” put in Tom. “People like excursions. We could put up signs in Barmouth and all along the road. ‘Be sure to take the boat to famous Cotterell Hall on Cotterell’s Island and hunt for the treasure!’ That would get them all right. You could charge as much as you like.”

“And Tom could run a ferry, and Ben be the care-taker and serve ginger-ale at a dollar a glass,” suggested David.

“And you could cork your face and be the famous mahogany man from the Barbadoes,” retorted Ben. “He’s a wonder in a minstrel show, Professor.”

“It sounds good,” Tuckerman agreed. “It’s certainly up-to-date. But somehow I don’t feel that it’s quite dignified enough for Cotterell Hall.”

“You can make it dignified enough,” said Tom, “by charging enormous prices.”

Tuckerman laughed. “You’re right. You fellows are Yankees sure enough. You make me feel like a greenhorn.”

“And think of the business it would bring to Barmouth,” said Ben, putting the attempt at a mermaid into his pocket and sitting up straight. “People who went to the island would probably have to spend the night at the hotel. Why, you ought to be able to make a deal with the proprietor to share his profits.”

“Ben’s started now,” exclaimed David. “Stop him somebody quick, or he’ll be spending the money we’re making from the concern.”
