Meantime, the dragoons crossed the bridge and poured down all abreast, receiving as they came, a straggling volley from the escopetas of the lancers, who seeing that flight was hopeless, stood to their arms like men, and making a desperate defense.

Then came a desperate race, for life or death, across the firm dry prairie, which echoed under the thundering horse-tramps firm, solid, and elastic.

The Mexican had, perhaps, gained a start of some fifty yards before his foe was across the brook, and his small but high-bred horse, being the fresher of the two, held his own for a little way, and even widened the gap at first, between himself and his pursuer. Ere long, however, the tremendous stride and power of the Anglo-American thorough-bred horse began to tell; and, at every stroke, the Partisan closed on him. Nor was the other slow to perceive the disadvantage. He stood up in his stirrups, looked quietly behind him, and seeing that none of the dragoons had passed the brook, but had dismounted and were now grouped about the fire, deliberately pulled his horse up, and, unslinging his escopeta, took a deliberate aim at Pierre Delacroix.

He fired. The ball whizzed through the air, so close to the head of the Partisan, that it severed one of his long, dark locks; but it passed onward harmless. Then, seeing the failure of his missile, the Mexican couched his long lance and rode at the frontiers-man with a savage yell.

Silently Pierre charged right upon him; but, when he was within a horse's length of the spear's point, he wheeled suddenly to the left, and as the Mexican was borne past him, delivered a straight lounge, en carte, which emptied his saddle in an instant, and left him but a minute's life to wrestle out on the greensward.

The Partisan had no time to give mercy, and he rode away to join Gordon and the lady; but, ere he did so, he met the prisoner in charge of the two soldiers who had brought up the mules, and the fellow, looking at him half askance, asked him in Spanish, with a sullen and almost savage intonation, whether he had not told him truly.

Pierre replied only by two words—"Very truly." But he noted the accent and half-sneering smile; and the first words he spoke as he joined the lieutenant, were:

"Confound that scoundrel! I have half a mind to reward him with one ounce of lead instead of two of gold."

"That were scarce worthy of you, Partisan," said Gordon, "and scarce worth the time. What harm can one poor devil like that do to six stout, well-armed fellows, such as we?"

"I do not know," answered Pierre, "I do not know; but right sure I am, that he is a double traitor."
