Tuesday, early in the morning, the army was in motion again toward the front, straggling down the track and across the field. Four hundred raging demons sweated and hammered at the ruined track; the foremost train had made half a mile in the night. Horses were plenty that morning, and I bought one, saddle and all, for seventy-five pesos—about fifteen dollars in gold. Trotting down by San Ramon, I fell in with two wild-looking horsemen, in high sombreros, with little printed pictures of Our Lady of Guadelupe sewed on the crowns. They said they were going out to an outpost upon the extreme right wing, near the mountains above Lerdo, where their company was posted to hold a hill. Why should I want to come with them? Who was I, anyway? I showed them my pass, signed by Francisco Villa. They were still hostile. "Francisco Villa is nothing to us,", they said. "And how do we know whether this is his name, written by him? We are of the Brigada Juarez, Calixto Contreras’ _gente_." But after a short consultation the taller grunted, "Come." We left the protection of the trees, striking out diagonally across the ramparted cotton-fields, due west, straight for a steep, high hill that already quivered in the heat. Between us and the suburbs of Gomez Palacio stretched a barren, flat plain, covered with low mesquite and cut by dry irrigation ditches. The Cerro de la Pila, with its murderous concealed artillery, lay perfectly quiet, except that up one side of it, so clear was the air, we could make out a little knot of figures dragging what looked like a cannon. Just outside of the nearest houses some horsemen were riding around; we immediately struck north, making a wide detour, carefully on the watch, for this intermediate ground was overrun by pickets and scouting parties. About a mile beyond, almost along the foot of the hill, ran the high road from the north to Lerdo. We reconnoitered this carefully from the brush. A peasant passed whistling, driving a flock of goats. On the very edge of this road, under a bush, was an earthen jar full of milk. Without the least hesitation the first soldier drew his revolver and shot. The jar split into a hundred pieces—milk spurting everywhere. "Poisoned," he said briefly. "The first company stationed over here drank some of that stuff. Four died." We rode on. Up on the hill crest a few black figures squatted, their rifles tilted against their knees. My companions waved to them, and we turned north along the bank of a little river that unrolled a narrow strip of green grass in the midst of desolation. The outpost was camped on both sides of the water, in a sort of meadow. I asked where the colonel was, and finally found him stretched out in the shade of a tent that he had made by hanging his serape over a bush.
