direction of the ponies showed they had ceased to crop the grass and were lying down. The safety of the camp was in his hands. If he forgot his duty, it might be fatal to all.

The sense of this responsibility and the newness of his position made Jack Dudley more wakeful than he could have been under any other circumstances. To these causes, also, was due a suspicious nervousness which made him see danger where it did not exist. The rustling of a falling leaf caused him to start and glance furtively to one side, and at a soft stir of the leaves under a breath of wind, or a slight movement of the sleeping ponies, he started and grasped his rifle with closer grip.

All this was natural; but there came a moment, not far from midnight, when there remained no doubt that some person or animal was moving stealthily through the grove, near where he was standing. It will be remembered that his position was such that the trunk of the large oak acted as an impenetrable screen between him and the camp-fire, which was burning so vigorously that its rays penetrated to a greater or less degree beyond him. Thus he could see anything moving within the circle of illumination, while he was as invisible to the keenest-eyed warrior as if the night was without a ray of light.

The first warning was through the sense of hearing. He had been deceived so many times that he suspected his fancy was playing with him again, but the faint tip, tip continued until such explanation was amiss.

"It is an Indian or a wild beast," was his belief.

The next minute he knew that, whatever it was, its position was between him and the outer edge of the grove. Since the ponies were on the opposite side of the fire, Jack was nearer the intruder than either they or his friends, sleeping by the camp-fire. Recalling that his place was the most favorable possible, he remained as motionless as the tree-trunk behind him, and to which he stood close enough to touch by moving his foot a few inches backward.

The situation being thus, it followed that if the man or beast continued its advance it must come into sight, while Jack himself was invisible. He therefore held his Winchester ready for instant use and waited.

He was standing in this expectant attitude when a remarkable thing took place. The fire, having remained unreplenished for some time, had subsided to a considerable extent, when one of the embers fell apart and caused such a displacement of the burning wood that the light flared up and penetrated with its former vigor beyond the tree which sheltered the sentinel.

Jack was as immovable as a statue, his weapon grasped in both hands, when this sudden brightening occurred. He was peering out among the dark trees, in the effort to identify the danger, when he saw the unmistakable figure of an Indian, hardly twenty feet away.

The buck had entered the grove with the silence of a shadow, and was making his way to the camp-fire, when betrayed in this singular manner to the watcher. In the reflection of the firelight, his naturally hideous countenance was repulsive to the last degree. The features were irregular, with prominent cheek-bones, a huge nose, and a retreating chin. Ugly as nature had made him, he had intensified it himself by daubing black, red and white paint in splashes over the front of his countenance. His coarse, black hair dangled loosely about his shoulders, and a single stained eagle's feather protruded from the crown. It was gathered back of the neck by a thong of some sort, so as to prevent the hair getting in his eyes when there was such imminent need for their use.

The chest was bare to the waist, and was also fantastically painted. In the girdle which encircled his waist was thrust a knife, whose handle protruded, while the leggings and moccasins were gayly ornamented and fringed. He held a formidable rifle in his right hand, in a trailing position, and was leaning well forward, with his body bent, as he drew near the camp with that stoical patience which the American race shows in the most trying crises. If necessary, he would continue this cautious advance for hours without showing haste, for it is often that his people circumvent and overthrow an enemy by their incomparable caution and care.

One peculiar feature of the unexpected flaring-up of the light was that its strongest force impinged directly upon the painted face of the Indian, which was seen as plainly by Jack Dudley as if the sun were shining. The youth felt that he could not forget that countenance if he saw it a hundred years afterward.

Had Jack followed the instruction of their guide he would have leveled his Winchester and shot the Indian dead in his tracks. The fellow was stealing into camp in such a manner that there could be no doubt the least crime he meant to commit was to steal. No ranchman or hunter would hesitate a moment, under the circumstances, to give him his eternal quietus.

But Jack Dudley could not do such a thing. To him it was an awful act to shoot a person, even though a savage, and his conscience would never permit him to do so until there was no choice left to him. He would much prefer to frighten away this intruder than to kill him.

The youth was so confident of his command of the situation that he would have felt hardly a thrill of alarm, but for the fear that the redskin belonged to a party near at hand who had sent him forward as a scout. Manifestly the right course for the sentinel was to discharge his gun, thus scaring the Indian and awaking Hazletine; but, while debating the question with himself, he became aware that the hostile was advancing.

The fellow did this with such marvellous cunning that Jack perceived no movement of his legs or feet. The latter were partly shrouded in shadow, but the Indian himself suggested a statue set up among the trees. Nevertheless he was inching toward the camp-fire, and was already a couple of yards nearer Jack than when the latter first noticed him.

Had he approached from the other side the youth never would have discovered his danger; but now he had his eye on the enemy, and meant to keep it there until the crisis was over. It was perhaps ten minutes later that the buck was within six feet of the youth, who, noiselessly bringing his Winchester to a level, took one step toward him and asked:

"Well, my friend, what do you want?"
