"One was dressed in gray and the other in dark-blue or black."

"That was the boat! Where did she go?" ejaculated Dick, who
remembered well how Mumps and Baxter had been attired, and the
pretty dress and hat Dora was in the habit of wearing.

"She was bound straight down the river."

"We must follow her."

"That's the talk!" burst out Tom. "But how?"

"What do you want to follow the Flyaway for?" asked Martin Harris
curiously.

"Those two boys are running away with that girl!"

"Impossible!"

"No, it isn't. One of the fellows -- the fellow in dark clothing
-- is the chap who ran into us that day."

"Well, now, do you know I thought it looked like him," was
Harris' comment. "And, come to think of it, that boat got as far
away from me as she could."

"Do you think you would know her again? I mean the Flyaway -- if
we got anywhere near her?" asked Dick.
