I had not slept a wink the two previous nights. The south fork of the Llano lay over twenty miles distant, and although it had ample water two weeks before, one of the foremen and I rode through to it that night to satisfy ourselves. The supply was found sufficient, and before daybreak we were back in camp, arousing the outfits and starting the herds. In the spring of 1878 the old military trail, with its rocky sentinels, was still dimly defined from Nueces Cañon north to the McKinzie water-hole on the South Llano. The herds moved out with the dawn. Thousands of the cattle were travel-sore, while a few hundred were actually tender-footed. The evening before, as we came out into the open country, we had seen quite a local shower of rain in our front, which had apparently crossed our course nearly ten miles distant, though it had not been noticeable during our night's ride. The herds fell in behind one another that morning like columns of cavalry, and after a few miles their stiffness passed and they led out as if they had knowledge of the water ahead. Within two hours after starting we crossed a swell of the mesa, when the lead herd caught a breeze from off the damp hills to the left where the shower had fallen the evening before. As they struck this rise, the feverish cattle raised their heads and pulled out as if that vagrant breeze had brought them a message that succor and rest lay just beyond. The point men had orders to let them go, and as fast as the rear herds came up and struck this imaginary line or air current, a single moan would surge back through the herd until it died out at the rear. By noon there was a solid column of cattle ten miles long, and two hours later the drag and point men had trouble in keeping the different herds from mixing. Without a halt, by three o'clock the lead foremen were turning their charges right and left, and shortly afterward the lead cattle were plunging into the purling waters of the South Llano. The rear herds turned off above and below, filling the river for five miles, while the hollow-eyed animals gorged themselves until a half dozen died that evening and night.
