“I must stop him!” exclaimed Maurice, “or the mares will run on till the end of daylight.”
As the mustanger spoke, he struck the spur sharply into the flanks of his horse. Like an arrow projected from its bow, Castro shot off in pursuit of the jackass, now galloping regardlessly past.
Half a dozen springs of the blood bay, guided in a diagonal direction, brought his rider within casting distance; and like a flash of lightning, the loop of the lazo was seen descending over the long ears.
On launching it, the mustanger halted, and made a half-wheel—the horse going round as upon a pivot; and with like mechanical obedience to the will of his rider, bracing himself for the expected pluck.
There was a short interval of intense expectation, as the wild ass, careering onward, took up the slack of the rope. Then the animal was seen to rise erect on its hind legs, and fall heavily backward upon the sward—where it lay motionless, and apparently as dead, as if shot through the heart!
It was only stunned, however, by the shock, and the quick tightening of the loop causing temporary strangulation; which the Mexican mustanger prolonged to eternity, by drawing his sharp-edged macheté across its throat.
The incident caused a postponement of the chase. All awaited the action of the guide; who, after “throwing” the macho, had dismounted to recover his lazo.
He had succeeded in releasing the rope from the neck of the prostrate animal, when he was seen to coil it up with a quickness that betokened some new cause of excitement—at the same time that he ran to regain his saddle.
Only a few of the others—most being fully occupied with their own excited steeds—observed this show of haste on the part of the mustanger. Those who did, saw it with surprise. He had counselled patience in the pursuit. They could perceive no cause for the eccentric change of tactics, unless it was that Louise Poindexter, mounted on the spotted mustang, had suddenly separated from the company, and was galloping off after the wild mares, as if resolved on being foremost of the field!
