The night was intensely still. Hardly a breath of wind stirred. Except for the occasional bellow of a restless steer or the never–ending refrain of Bud’s song, the plains on the border of the Rio Grande were as silent as a country churchyard. Jack resumed his ride. He began whistling. It was not a cheerful tune he chose. “Massa’s in the Cold, Cold Ground,” was his selection. Somehow it seemed to the lad that such a tune was suited to the night and to his task. Jack’s course led him to the south of the herd, between the main body of cattle and the Rio Grande. He kept a bright lookout as he passed along the river banks. He knew that if trouble was coming, it was going to come from that direction. Almost unconsciously he felt his holsters to see if his weapons were all right. Once he paused to listen. It was at a spot right on the river bank that he made his halt. He was just about to ride on again, whistling his lugubrious tune, when something odd caught his eye and set his heart to thumping violently. A head covered with a white hood containing two eyeholes had suddenly appeared above the river bank. The next instant a score more appeared. All wore the white hoods with the same ghastly eyeholes, giving them the appearance of so many skulls. Greatly startled and alarmed, Jack yet realized that the figures that had appeared so suddenly must be those of cattle–stealing Mexican rebels and that they had adopted the hoods with the idea of scaring the superstitious cowboys. Hardly had he arrived at this conclusion before the hooded horsemen rushed up the bank. They aimed straight for the boy. Instantly Jack’s hand sought his holster. Bang! Bang! Bang! It was the three shots agreed upon as a signal of trouble. From far back on the eastern side of the herd came an answer. Jack had just time to hear it when the hooded band swept down upon him. He felt bullets whiz past his ear and then, without exactly knowing how it happened, he was riding for his life, crouched low on Dynamite’s withers. Off to the north, east and west other six–shooters cracked and flashed. The signal of alarm was being passed around rapidly. Jack was riding for his life toward the west side of the herd. Behind him pressed one of the hooded horsemen. All the others had been distanced by the fleet–footed Dynamite. But this man behind him clung on like grim death. From time to time he fired, but at the pace they were going his aim was naturally poor and none of the bullets went near the fleeing boy on the buckskin pony. The air roared in Jack’s ears as he dashed along. All at once he became conscious of another roar, the roar of hundreds of terrified steers. Horns crashed and rattled. Startled bellows arose. Then off to the east came more firing. Jack judged by this that most of the hooded band had gone off in that direction and were now engaged in fighting with Bud and the rest of the cattle watchers.
