“john clark’s voice dropped almost to a whisper. ‘you’ll take the string of six horses to the ford at plover’s creek.’”

“his father nodded. ‘meanwhile, you must get those horses delivered. they’ll be used in the continental army.’”

“‘this boy can do it,’ john clark answered at last. ‘i know he can.’”

“he looked hard at will. ‘yes, he’s too young,’ john clark agreed.”
