“We’ll just keep it to ourselves, you know,” warned Dan. “Mr. Robert Darringford is going to offer a handsome prize for the fastest iceboat at the regatta we’re going to hold. Don’t you know that?”

“Well—er—yes.”

“Then we’ll just keep still about this scheme. Some of the parts will have to be made in the machine shops, you know. And some parts we’ll get old Troutman, at Compton, to make. You remember him?”

“Sure! the pattern maker who worked for Mr. Asa Craig when Mr. Craig was building his submarine.”

“The same. We won’t let anybody but father see the plans as completed. No use in letting ’em in on the scheme.”

“Crickey, Dan!” exclaimed Billy. “If we build a racer that wipes up the whole river, Barry Spink will turn green with envy. I heard him blowing the other day that he was going to have some kind of a mechanical contrivance built for his White Albatross that would make her the fastest thing on the ice.”

“That’s all right. Maybe he’s got something good up his sleeve,” laughed Dan. “But I believe that we have something just a little better here,” and he tapped the plans on the table.
