n, the active fancy of the youth saw the
lovely face of Marion looking at him with mournful interest, as it had
been the face of an angel, and then there came to his memory words which
had been spoken to him that very day by his earnest friend Stevenson the
marine: "No man can fully do his duty to his fellows until he has begun
to do his duty to God."

The words had not been used in reference to himself but in connection
with a discussion as to the motives generally which influence men. But
the words were made use of by the Spirit as arrows to pierce the youth's
heart.

"Guilty!" he exclaimed aloud, and almost involuntary followed, "God
forgive me!"

Again the watchful ear distinguished unwonted sounds, and the sharp
eye--wonderfully sharpened by frequent danger--perceived objects in
motion on the plain. This time the objects were real. They approached.
It was "the rounds" who visited the sentries six times during each
night.

In another part of the ground, at a considerable distance from the spot
where our hero mounted guard, stood a youthful soldier, also on guard,
and thinking, no doubt, of home. He was much too young for service in

exposing himself in a way that had already cost so many men their lives.

But young Lewis laughed good-naturedly, and said that he was too tough
to be killed by the sun.

The suffocating heat of that night told upon him, however, severely--
tough though he was or supposed himself to be--while he kept his lonely
watch on the sandy plain.

Presently a dark figure was seen approaching. The sentinel at once
challenged, and brought his rifle to the "ready." The man, who was a
native, gave the password all right, and made some apparently
commonplace remark as he passed, which, coupled with his easy manner and
the correct countersign, threw the young soldier off his guard.
Suddenly a long sharp knife gleamed in the faint light and was drawn
across the body of Lewis before he could raise a hand to defend himsel
