Dick, do you notice how the wind is freshening? "Yes, Sam, I've been watching it for ten minutes. I think we are in for a storm." "Exactly my idea, and I shouldn't be surprised if it proved a heavy one, too. How far are we from shore?" "Not over three miles, to my reckoning." "Perhaps we had better turn back," and Sam Rover, the youngest of the three Rover brothers, shook his head doubtfully. "Oh, I reckon we'll be safe enough," responded Dick Rover, who was several years older. "I know more about sailing a yacht than I did when we followed up the Baxters on the Atlantic Ocean."
