Vague, ghostly figures moved over the open plain, finding cows with uncanny directness and certainty. Two riders held the nucleus of the little herd, which grew steadily as lumbering cows, followed inexorably by skilled riders, pushed out of the darkness. There was no conversation, no whistling now, nor singing, but a silence which, coupled to the ghost-like action and the dexterous swiftness, made the drama seem unreal.

There came an abrupt change. The two men riding herd saw no more looming cattle or riders, which seemed to be a matter of significance to them, for they faced southward, guns in hand, and pushed slowly back along the flanks of the little herd. Peering into the shrouding gray darkness, tense and alert, eyes and ears straining to read the riddle, they waited like sooty statues for whatever might occur, rigid and unmoving.

A sudden thickening in the night. A figure seemed to flow from indefinable density to the outlines of a mounted man. A low voice, profanely irritant, spoke reassuringly and grew silent as the rider oozed back into the effacing night.

"Shore," muttered a herder, relaxing and slipping his gun into its holster. He moved forward swiftly and turned back a venturesome cow. His companion, growling but relieved, shrugged his shoulders and settled back to wait.

Minutes passed and then another lumbering blot emerged out of the dark, became a cow, and found reassurance in numbers as it willingly joined the herd. The escorting rider kept on, pushed back his sombrero and growled: "They're scattered to h—l an' gone tonight; but," he grudgingly admitted, "they acts plumb do-cile. S'long."

Another wait, long and fruitless, edged anew the nerves of the herders. Then Quigley, Ackerman, and Purdy moved out of the obscurity of the night and took up positions around the herd, urging it forward. When they had it started on its way, Ackerman dropped back and became lost to sight, engaged in his characteristic patrolling, suspicious and malevolent.

The little herd, skilfully guided over clean patches of rock which led deviously to the water's edge and left no signs on its hard surface, at last reached the river, where a shiver of hesitancy rippled through it and where the rear cows pushed solidly against the front rank, which appeared to be calling upon its inherent obstinacy. The craft and diplomacy of Quigley's long experience won out and the uncertain front rank slowly and grudgingly entered the stream, the others following without noticeable hesitation. As the last cow crossed and scrambled up the western bank, Ackerman rode down to the water's edge, pushed in and crossed silently, only the lengthening ripple on the black surface telling of his progress. As he climbed out he squirmed in his wet clothes and swore from sudden anger, which called forth a low ripple of laughter from the base of the Barrier, where the others took their discomforts lightly.

"Scared you'll shrink, Jim?" softly said an ironic voice.

"Or dissolve, like sugar?" inquired another scoffingly.

"Sugar?" jeered a third. "Huh! He's about as sweet as a hunk of alum!"
