to decide it myself--'cause--'cause Mr. Ellsworth--a man I
know--ain't here. Maybe a feller's own family come first and I
wouldn't--I wouldn't--tell on 'em--if--if they stole--or something like
that," he blurted out, twisting his fingers together. "And--and--I
didn't forget neither--I didn't," he added, turning and looking his
brother straight in the face, "I didn't--I----"

He broke down completely and the men stared at him, waiting.

"Anyway--anyway--I got to remember----" He broke off.

"Well, what became of the light?" the officer urged rather coldly.

"And when you saw me standing on the--deck--last night--I was thinking
about Uncle Sam----" He gulped and hesitated, then went on,
"and--and--that's what made me think about Uncle Sam being a relation

"It ain't 'cause I don't remember--but--I had to decide--and I got to
stand by Uncle Sam!"

"If you didn't know about this," said the captain, watching him keenly,
"how did you suspect it? You'd better try to control yourself and tell
everything. This is a very serious matter."

"You see that piece of cotton waste that you kicked?" said Tom, turning
upon the disguised government agent. "You can see it's fresh and hasn't
