Yet it was apparent his pursuit of the stranger had signally failed, and he stood motionless wondering what course then best for him to adopt.

True, he was in a dilemma, and instinctively realized that to remain in the park was useless. So, without forming any practical conclusion, and for the purpose of keeping active, he again moved toward the fence. It was then he conceived the notion to climb over the fence and make a short descent to the gate, in order to catch sight of Virginia, for she could not be far away yet, and to follow her and secretly to protect her on her return to her home. With that object in mind, he climbed the fence, and, securing a position on its top, looked cautiously about. He was some distance to the west of the tangle of vines, from which he was screened by the foliage of a small tree that grew nearby.

Sam—“One of those deadly reptiles got out of the Park Zoo.”

The gate light threw a faint glimmer along the fence, and on the Barnes road in the gorge below. He peered down the steep hillside, and looked up and down the road. There being no one in sight, he let his legs slip quietly down the other side of the fence, and gradually lowered himself, without sustaining other injury than a few trivial scratches. As he brushed mechanically the debris which had clung to his clothes, he was surprised to see the figure of a man step out, seemingly from the fence itself, and slip down the hillside, and climbing the lower fence, cross the almost dry bed of the stream, close to the road, and proceed cityward.

Sam was sure the man, whoever he was, had not been on the corral side of the fence a moment before, and to give the mysterious appearance a deeper significance, the point of exit was about the location of the tangled vines. The appearance of the man differed from the one he had followed, inasmuch that one had on a long coat and bushy beard, the other wore a short pilot coat and mustache. For a moment Sam was puzzled, and he scratched his head. Suddenly he broke out in an unconscious whisper to himself, as though urged on by some supernatural agency, for afterward it surprised him when he thought of that moment: “Damned if I don’t think he’s the same party I’ve been after, disguised.”

And he made straight for the place, as near as he could estimate, where the man had emerged.

It was a few moments before he found it, but a close examination soon revealed two yielding pickets of the fence. True, just sufficient to admit a man’s body sideways, but there it was, as he afterwards discovered, and perfectly screened from observation by masses of slender leaf-laded branches and twigs. The inner, bushy part being skilfully cut away. The trick employed to evade him was now palpable. The hiss, the buzzing rattle, the glitter—“Ah; it was the glitter of a steel blade”—and at the thought he shivered, as with an icy chill, for he realized how dangerously near a death-trap he had ventured. As the reaction came, his face flamed with the hot blood of indignation and chagrin at the smart dodge by which he had been temporarily baffled.

In the distance, down near the park entrance, was still dimly visible the retreating form of a man. Sam determined to follow him.

He slid and partly tumbled down the steep hillside, sprang over the lower fence, and crossed the bed of the creek and on to the road—and was so intent on his mission that he did not hear or see, until it was almost upon him, a dark, noiseless machine, approaching from the rear. He moved hastily aside to let it pass, but to his intense astonishment, the automobile followed him with evident intention of running him down. Again he sprang aside, but too late. The front wheel grazed his left leg and swung him around on to the rear wheel, which hurled him violently to the ground.
