A low growl running through the crowd finished his threat for him. It would have fared badly with Black Ramon had he been there then. But he was far away, riding for the mountains, where he would be safe from the ranchmen's vengeance.

"Waal, we'll run acrost his tracks some day," growled Bud Wilson, "and when we do——Waal, let's talk about the weather."

The boys said nothing, but their faces spoke volumes. By this time, such was the heat of the sun, Ralph's clothes had almost dried out, and he was assured that he would suffer no ill effects from his immersion. As Jack was also almost dry, the rancher, who, it turned out, was a friend of Mr. Merrill's, invited the Agua Caliente party in to have something to eat while their houses were rubbed down and fed. After more congratulations and expressions of wonderment, the horsemen from Maguez rode back to town, and when they had spread the story, the atmosphere of that part of the country would have proved very unhealthful for Black Ramon. Indeed, there was talk of fitting up an expedition to go out and get him, but it was surmised that the Mexican had probably ridden over the border and taken sanctuary in one of his retreats.

"Speaking of irrigation, I'm afraid we are going to have serious trouble with the water some day," Mr. Hungerford, the rancher, remarked as they sat at their meal.

"You mean your orchards will be overflowed?" inquired Jack.

"Oh, no. I'm not afraid of that. That pool in which you landed from the tunnel is drained by a score of small ditches which ought to be capable of handling any overflow. No, the ranches I mean are the ones back under the hills—the cattle ranges. The dam back near Grizzly Pass is none too strong, I am told, and if at any time following a cloudburst the sluiceways should not be opened in time, the retaining wall might burst, and the whole country be swept by a disastrous flood. Damage to thousands of dollars' worth of property and the death of scores of men and cattle might also be a consequence."

"But surely the dam is well guarded?" asked Ralph.

"That's just the trouble," said Mr. Hungerford seriously. "At night, I understand, only one old man is on watch there, and if he should meet with an accident there would be no one to watch for the safety of the ranchers in the foothills."
