Occasionally the door of the Casa Grande vomited mounted men—two or three at a time—who galloped down the Puerta road with their rifles in their hands. I could follow them as they rose and fell over the waves of the desert, growing smaller all the time, until they mounted the last roll—where the white dust they kicked up caught the fierce light of the sun, and the eye couldn’t stand it. They had taken my horse, and Juan Vallejo didn’t have one. He stood beside me, cocking and firing his empty rifle. "Look!" he shouted suddenly. The western face of the mountains that flanked the Puerta was in shadow still. Along their base, to the north and to the south, too, wriggled little thin lines of dust. They lengthened out—Oh so slowly. At first there was only one in each direction; then two others began, farther down, nearer, advancing relentlessly, like raveling in a stocking—like a crack in thin glass. The enemy, spreading wide around the battle, to take us in the flank! Still the little knots of troopers poured from the Casa Grande, and spurred away. Pablo Arriola went, and Nicanor, waving to me brightly as they passed. Longinos Güereca rocketed out on his great _tordillo_ horse, yet only half broken. The big gray put down his head and buck-jumped four times across the square. "To-morrow for the mines," yelled ’Gino over his shoulder. "I’m very busy to-day—very rich—the lost mines of——" But he was too far away for me to hear. Martinez followed him, shouting to me with a grin that he felt scared to death. Then others. It made about thirty so far. I remember that most of them wore automobile goggles. Don Petronilo sat his horse, with field-glasses to his eyes. I looked again at the lines of dust—they were curving slowly down, the sun glorifying them—like scimitars. Don Tomas galloped past, Gil Tomas at his heels. But someone was coming. A little running horse appeared on the rise, headed our way, the rider outlined in a radiant dust. He was going at furious speed, dipping and rising over the rolling land.... And as he spurred wildly up the little hill where we stood, we saw a horror. A fan-shaped cascade of blood poured from the front of him. The lower part of his mouth was quite shot away by a soft-nosed bullet. He reined up beside the colonel, and tried earnestly, terribly, to tell him something; but nothing intelligible issued from the ruin. Tears poured down the poor fellow’s cheeks. He gave a hoarse cry, and, driving his spurs deep in his horse, fled up the Santo Domingo road. Others were coming, too, on the dead run—those who had been the Puerta guard. Two or three passed right through the hacienda without stopping. The rest threw themselves upon Don Petronilo, in a passion of rage. "More ammunition!" they cried. "More cartridges!" Don Petronilo looked away. "There isn’t any!" The men went mad, cursing and hurling their guns on the ground.
