Leading his horse by the bit ring, Hilario moved out into the clearing, followed once more by his three companions. Concealment was out of the question now, for their only covering was the darkness. O'Reilly had the uncomfortable feeling that the cavalcade bulked monstrous big and must be visible at a great distance; he experienced much the sensations of a man crossing a sheet of thin ice with nerves painfully strained, awaiting the first menacing crack. In spite of all precautions the animals made a tremendous racket, or so it seemed, and, despite Hilario's twistings and turnings, it was impossible to avoid an occasional loop of barbed wire, therefore flesh and clothing suffered grievously. But at length the party brought up under the railroad embankment and paused. Out of the voids to their right came a faint murmur of voices. As carefully as might be the four men ascended the slope, crossed the rails, and descended into the ditch on the other side. Another moment and they encountered a taut strand of barbed wire. The metallic snip of Hilario's shears sounded like a pistol-shot to O'Reilly. Into the maze of strands they penetrated, yard by yard, clipping and carefully laying back the wire as they went. Progress was slow; they had to feel their way; the sharp barbs brought blood and muttered profanity at every step. None of the four ever knew what gave the alarm. Their first intimation of discovery came with a startling "Quien vive?" hurled at them from somewhere at their backs. An instant and the challenge was followed by a Mauser shot. Other reports rang out as the sentry emptied his rifle in their direction. "So! They are shooting-bats," Hilario grunted. Antonio swung about and cocked his Remington, but the other spoke sharply. "Fool! If you shoot they will see the fire and riddle us. A curse on the spider that spun this web!" It was a test of courage to crouch among the charred stumps, enmeshed in that cruel tangle of wire, while the night was stabbed by daggers of fire and while the trocha awoke to the wild alarm. From somewhere in the distance came a shouted command and the sound of running feet, suddenly putting an end to further inaction. Antonio began to hack viciously with his machete, in an effort to aid Hilario's labors. The sound of his sturdy blows betrayed the party's whereabouts so clearly that finally the older man could restrain himself no longer. "Give it to them, compadres; it is a game that we can play."
