The time was about midnight the night following Jack’s little argument with Dynamite. Since nine o’clock the Border Boys had been on duty with the Reeves herd. Under the bright stars the cattle were visible only as a black, evershifting mass, round and round which the boys, Bud and two cow–punchers circled unceasingly. Some of the animals were feeding, others standing up or moving about. The air reeked of cattle. Their warm breaths ascended into the cool night in a nebulous cloud of steam.

From far off came the sound of a voice singing, not unmusically, that classic old ballad of the Texas cowman:

“Lie quietly now, cattle,
And please do not rattle,
Or else we will ‘mill’ you,
As sure as you’re born.

A long time ago,
At Ranch Silver Bow,
I’d a sweetheart and friends,
On the River Big Horn“

Jack pulled up his pony for a minute and listened to the long drawn, melancholy cadence. It was the cow–puncher’s way of keeping the cattle quiet and easy–minded. Steers at night are about as panicky creatures as can be imagined. The rustle of the night wind in the sagebrush, the sudden upspringing of a jackrabbit, the whinnying of a pony, all these slight causes have been known to start uncontrollable “stampedes“ that have been costly both to life and property.

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.
