After this last effort the thing was accepted as routine. There was a childishness, a puerility about it that made the men smile. They grew rather to like this little excitement, breaking the monotony of long vigils.

But gradually the affair grew more interesting. The man was learning to shoot. Each night the leaden missile screeched a little lower, a little closer. Finally, one night, the guard, when relieved, was found walking his post with his left arm limp along his side, neatly punctured by one of the mysterious bullets.

On the same morning, Blount, walking along the main street, was stopped by old Eustefania.

"Mi capitan," she said, cringing before him, "do you wish to know who shoots your soldiers at night?"

"Who?" asked the Sergeant curtly.

"Caybigan," she said.

From the depths of their caves her eyes glowed at him, fixed, violent.

And to the Sergeant the answer came as the revelation of something long and obscurely felt. Caybigan's absence from the night alarms, his singular failure to track down the sharpshooter, the ridiculous fiasco of the attempted ambuscade—a thousand and one little links suddenly clinked shut at the word in a chain of evidence, of certainty.

The Sergeant turned sharp on his heel; his spurs rang on the stone flagging. In the centre of the plaza Caybigan, in his graceful, elastic pose, half-confident, half-wild, was bandying with three of the blue-shirted soldiers. Blount made straight for the group. When near he began to run, his face convulsed with the rage, half real, half assumed, which experience had taught him invaluable for such moments. With a tiger leap he bore upon Pedro, clutched his throat with his great hands, and threw him to the ground.

Pedro went down without a quiver of resistance, and he lay there a white figure in the gray dust, his arms thrown out in a cross-like attitude of infinite surrender. His brown eyes looked up into the cold green light of the Sergeant's with golden luminosity; he smiled gently. "And this from my caybigan," he said.
