Suddenly he was back in Egypt with his heart thumping at his ribs. An object seemed to move on the plain in front of him. The ready bayonet was lowered, the trigger was touched. Only for a moment, however. The shadow of a cloud had passed from behind a bush—that was all; yet it was strange how very like to a real object it seemed to his highly-strung vision. A bright moonbeam next moment showed him that nothing to cause alarm was visible.

Mind is not so easily controlled as matter. Like a statue he stood there in body, but in mind he had again deserted his post. Yet not to so great a distance as before. He only went the length of Alexandria, and thought of Marion! The thought produced a glow, not of physical heat—that was impossible to one whose temperature had already risen to the utmost attainable height—but a glow of soul. He became heroic! He remembered Marion’s burning words, and resolved that Duty should henceforth be his guiding-star!

Duty! His heart sank as he thought of the word, for the Something within him became suddenly active, and whispered, “How about your duty to parents? You left them in a rage. You spent some time in Portsmouth, surrounded by good influences, and might have written home, but you didn’t. You made some feeble attempts, indeed, but failed. You might have done it several times since you landed in this country, but you haven’t. You know quite well that you have not fully repented even yet!”

While the whispering was going on, 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 such a climate—almost a boy. He was a ruddy, healthy lad, with plenty of courage and high spirit, who was willing to encounter anything cheerfully, so long as, in so doing, he could serve his Queen and country. But he was careless of his own comfort and safety. Several times he had been found fault with for going out in the sun without his white helmet. Miles had taken a fancy to the lad, and had spoken seriously but very kindly to him that very day about the folly of 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.
