“He’s going to build a wonderful boat to beat anything you boys can put on the river,” sighed Mildred. “He’s going to win all the ice races at the regatta Mr. Darringford is arranging. Oh! I heard him telling all about it the other evening at Mary Greene’s.”

“Don’t let that worry you for a little minute,” Billy broke in, with some excitement. “Dan’s got the plans of a boat right in his pocket now that will knock the eye out of any craft that will be on the ice this winter.”

“I admire your slang!” exclaimed Lettie, with scorn.

“I bet I caught it from you,” returned Billy, ready to “scrap” on the instant.

“Be good! be good!” cried Mildred. “Oh, Dannie! you are overtaking that white boat.”

“That’s what we’re here for,” returned the older boy, who had been attending strictly to business since Spink had challenged them.

The Fly-up-the-Creek was making good its name. They were rushing up the river at a terrific pace. The White Albatross, whenever she tacked, lost ground. And finally when they came to the lower end of Island Number One, she had to make a long leg towards the farther side of the river, and so get to the leeward of the island.

Billy was staring at the island all the time they were passing.

“What’s the matter, Billy?” demanded Lettie Parker. “What do you expect to see over yonder?”

“Billy’s looking for Robinson Crusoe,” chuckled Dan. “He believes there’s a fellow living over there.”
