On the opposite side of the river in bands of two and three thousand the cohorts of the sheep gathered to make the crossing--gathered and waited, for the Salagua was still high. At the foot of the high cliffs, from the cleft canyon of which water flowed forth as if some rod had called it from the rock, the leaders of the sheepmen were sitting in council, gazing at the powerful sweep of the level river, and then at the distant sand bar where their charges must win the shore or be swept into the whirlpool below. Ah, that whirlpool! Many a frightened ewe and weakling lamb in years past had drifted helplessly into its swirl and been sucked down, to come up below the point a water-logged carcass. And for each stinking corpse that littered the lower bar the boss sheep owner subtracted five dollars from the sum of his hard-earned wealth. Already on the flats below them the willows and burro bushes were trembling as eager teeth trimmed them of their leaves--in a day, or two days, the river bottom would be fed bare; and behind and behind, clear to the broad floor of the desert, band after band was pressing on to the upper crossing of the Salagua. As Hardy rode up over the rocky point against which the river threw its full strength and then, flung inexorably back, turned upon itself in a sullen whirlpool, he could see the sheep among the willows, the herders standing impassive, leaning upon their guns as more rustic shepherds lean upon their staves, and above, at the head of the crossing, the group of men, sitting within the circle of their horses in anxious conference. If any of them saw him, outlined like a sentinel against the sky, they made no sign; but suddenly a man in a high Texas hat leaped up from the group, sprang astride his mule and spurred him into the cold water. For the first twenty feet the mule waded, shaking his ears; then he slumped off the edge of a submerged bench into deeper water and swam, heading across the stream but drifting diagonally with the current until, striking bottom once more, he struggled out upon the sand spit. The rider looked eagerly about, glanced up casually at the man on the point below, and then plunged back into the water, shouting out hoarse orders to his Mexicans, who were smoking idly in the shade of overhanging rocks. Immediately they scrambled to their feet and scattered along the hillside. The stroke of axes echoed from the crags above, and soon men came staggering down to the river, dragging the thorny limbs of _palo verdes_ behind them. With these they quickly constructed a brush fence in the form of a wing, running parallel to the cliff and making a chute which opened into the river.
