In fine, he arrives at the conclusion that Conchita—long loved by him, long vainly solicited—has surrendered her heart to the gigantic Texan, who like a sinister shadow, a ghoul, a very ogre, has chanced across the sunlight of his path.

Under the circumstances, what is he to do? He is powerful in passion, but weak in physical strength. Compared with his rival, he is nought. In a conflict the Texan would crush him, squeeze the breath out of his body, as a grizzly bear would that of a prairie squirrel or ground gopher.

He does not show open antagonism—does not think of it. He knows it would but end in his ruin—his utter annihilation.

Still, he is not despairing.

With the instincts peculiar to his race, he contemplates revenge. All his idle hours are spent brooding over plans to frustrate the designs of his rival—in short, to put him out of the way altogether.

More than once has a thought of poison passed through his mind as the surest way of effecting his fiendish purpose, as also the safest; and upon this mode of killing the Texan he has at length determined.

That very day he has been engaged in making ready for the deed—preparing the potion. Certain plants he has found growing in the valley, well known among his people as poisonous, will furnish him with the means of death—a slow, lingering death, therefore all the surer to avert suspicion from the hand that has dealt it.

To all appearance, Walt Wilder is doomed. He has escaped the spears, arrows, and tomahawks of the Tenawa savages to fall a victim to a destroyer, stealthy, subtle, unseen.

And is the noble Texan—guide, ranger, and hunter—thus sadly to succumb? No. Fate has not decreed his death by such insidious means. A circumstance, apparently accidental, steps in to save him. On this very day, when the poison it being prepared for him, the poisoner receives a summons that for the time at least, will frustrate his foul plans. His master commands him to make ready for a journey. It is an errand similar to that he has been several times sent upon before. He is to proceed to the settlements on the Rio Grande, where Don Valerian has friends with whom, in his exile, he keeps up secret correspondence, Manuel acting as messenger. Thence the trusted peon is to bring back, as oft before, despatches, news, provisions—the last now more than ever needed, on account of the stranger guests so unexpectedly thrown upon his hospitality.

Manuel is to commence his journey on the following day at the earliest hour of dawn. There will be no chance for him now to carry out his nefarious design. It must remain uncompleted till his return.
