and, true to his detective instincts and education, began a diligent
search of the place.

He was actively engaged in this work when the sound of hasty footsteps
reached his ears. Throwing himself flat on the floor, behind a pile of
barrel staves, he drew his revolver and waited. The steps passed by,
however, and Sam quickly but quietly left the shop.

He could barely see the form of a man walking rapidly down the street to
the horse-car track.

As he passed the window of the saloon the light fell on him, and Sam saw
it was one of the two men who had just left the cooper-shop.

Following closely, using all his skill as a successful shadow, he
trailed the man to the car, and boarding the front platform rode into
town.

Passing a livery stable the man left the car, still followed by Sam.

When Moriarity, for it was he whom Sam was trailing, rode back to the
river, Sam was perched on behind the hack.

He saw the wounded Chip placed inside, thanks to the darkness, and still
hanging on the back of the carriage was carried back to town.

When the two train robbers turned into the alley Sam was right behind
them, so close that he could hear their labored breathing. Suddenly, as
if they had been swallowed by the earth, he was left alone in the dark,
nonplussed and outwitted.
