a shabbily dressed old
man then in sight, whom she often had met. Sir Donald recalls frequently
having seen this same seedy, aged individual. They slowly walk along
with well-dissembled unconcern, turning several unusual corners, with
the old pedestrian always in view. They will keep watch of this stranger
without arousing his suspicion.

That afternoon Sir Donald employed a small boy to accompany him at a
short distance, ready at a given signal to follow an old, poorly dressed
man, learn his home, and give immediate notice.

In the evening the boy reported having trailed this old party for
several hours, until he was lost in a distant part of the city.

The boy was engaged for further service and cautioned not to tell, but
to watch every day for Sir Donald's appearance on the street.

This spying is kept up for over a week, the stranger mysteriously

place of disappearance is reached. The new picket runs up, and both boys
stroll along down this last turn of narrow lane, following a
black-whiskered, neatly dressed, quick-stepping fellow, until entering a
stairway he is lost to sight.

The boys return and report.

The game has been located, and Sir Donald can investigate at leisure.

Having driven past this stairway before sunrise of the next day, and
noted the surroundings, Sir Donald returns to his hotel, charges the
little fellows to say nothing, pays them well, and dispenses with their
services.

After making the final turn, this stooping, slow-paced, shabbily dressed
form is changed into an erect, agile, dapper, dudish-looking specimen,
