butternut's directions, and the rebel's name was borne on the
door-plate. The house, however, was deserted; the blinds were closed, as
were those of all the neighboring houses. Mr. Abbott, with his family,
if he had any, had doubtless removed out of reach of the Union forces.
Did he ever visit his home when in town? or did he make his
head-quarters somewhere else? were questions that suggested themselves
to Frank, but which, of course, he could not answer; neither did he dare
to question any of the citizens, for they might be Mr. Abbott's friends,

coal, which he threw at Frank. It proved, however, to be a torpedo, for
it exploded with a loud report, and as Frank sprang over a fence that
ran close by the sidewalk, to escape, he came violently in contact with
