Danger threatened here in a mysterious, invisible fashion and he could only wait.

He saw a bush move again, but much nearer, and then came the crack of a rifle. If his horse, alarmed perhaps, had not thrown up his head suddenly, and received the bullet himself the lad's career would have ended there.

The horse made a convulsive leap, then staggered for a few seconds, giving his rider time to spring clear, and fell among the bushes. Dick dropped down behind him and quickly unstrapped the rifle from the saddle, meaning to use the animal's body as a breastwork against renewed attack.

His fear, the kind of fear that the bravest feel, had been driven away by rage. The killing of his innocent horse, although the bullet was intended for him, angered him as much as if he had received a wound himself. The spirit of his ancestor, the shrewd and wary Indian fighter, descended upon him again, and, lying upon his stomach behind the horse, with the rifle ready he was anxious for the attack to come.

Dick was firmly convinced that he had but a single enemy. Otherwise he would have been attacked in force earlier, and more than one shot would have been fired. But the report of the rifle was succeeded by deep silence. The forest was absolutely still, not a breath of wind stirring. His enemy remained invisible, but the besieged youth was confident that he was lying quiet, awaiting another chance. Dick, still hot with anger, would wait too.

But other enemies were far more reckless than the hidden marksman. The swarm of gnats, flies, and mosquitoes assailed him again and he could have cried out in pain. His only consolation lay in the fact that the other man might be suffering just as much.

He was aware that his enemy might try a circling movement in order to reach him on the flank or from behind, but he believed that his ear would be keen enough to detect him if he came near. Moreover he lay in a slight dip with the body of the horse in front of him, and it would require an uncommon sharpshooter to reach him with a bullet. If he could only stand those terrible mosquitoes an hour he felt that he might get away, because then the night would be at hand.

He saw with immense relief that the sun was already very low. The heat, gathered in the woods, was at its worst, and over his head the mosquitoes buzzed and buzzed incessantly. It seemed to him a horrible sort of irony that he might presently be forced from his shelter by mosquitoes and be killed in flight to another refuge.

But he was endowed with great patience and tenacity and he clung to his shelter, relying rather upon ear than eye to note the approach of an enemy. Meanwhile the sun sank down to the rim of the wood, and the twilight thickened rapidly in the east. Then a shot was fired from the point from which the first had come. Dick heard the bullet singing over his head, but it gave him satisfaction because he was able to locate his enemy.

He sought no return fire, but lay in the dip, wary and patient. The sun sank beyond the rim, the western sky flamed blood red for a few moments, and then the Southern night swept down so suddenly that it seemed to come with violence. Dick believed that his escape was now at hand, but he still showed an infinite patience.

He did not stir from his place until the night was almost black, and then, carrying his weapons and the saddlebag of provisions, he crept among the thickets.

When he stood up he found himself stiff from lying long in a cramped position. His face burned from the bites of the mosquitoes, which still hung in swarms about him, and he felt dizzy.

But Dick remembered his mission, and his resolve to perform it was not shaken a particle. He had lost his horse, but he could walk. Perhaps his chance of success would be greater on foot in such a dangerous country.

He advanced now with extreme caution, feeling the way carefully and testing the ground before he put his foot down solidly. Still trusting to his ears he stopped now and then, and listened for some sound from his enemy in pursuit. But nothing came, and soon he became quite sure that he had shaken him off. He was merely a dot in the wilderness in the dark, and, feeling secure now, he pressed forward with more speed.

He was hoping to get to a piece of firm, high ground, where he might secure a measure of protection from those terrible mosquitoes which still buzzed angrily about his head. In an hour chance favored him, as he reached a low ridge much rockier than usual in that region. He would have built a little smudge fire to protect himself from the mosquitoes, but it would be sure to draw the lurking sharpshooter, and instead he found a nook in the ridge, under the low boughs of a great oak. Then he took a light blanket which he carried tied to his saddlebags, and wrapped it around his neck and face, covering everything but his mouth and eyes.

He sank into the nook with his back against the turf, and the reclining position was wonderfully easy.
