"I stayed right here," was the reply. "Of course I kept my mouth shut about what I had seen. I worked on ranches and rode range and at last got the little place on Terry Creek and married. Nothing strange in my remaining in the country where I grew up, especially as I only knew the cattle business." Weir swung about to Madden. "Here's a live witness," said he. "With the other proof his evidence should be final." "Whenever you say, I'll arrest the men. As for this warrant I have, I'll just continue to carry it in my pocket," the sheriff stated. "I must remark that I never heard of a more villainous plot, taking it all around, than you've brought to light." "And the charges must cover everything," Pollock said sternly. "From Dent's murder to the conspiracy against the irrigation company." "I'll stay here in case you need me to stop any trouble with your workmen," Madden remarked. But trouble though imminent was coming from another direction, as was suddenly shown when a man, dust-covered and hatless, rushed into the office. "They're on the way," he cried. "Who? The workmen?" Weir demanded. "No. I don't know anything about the workmen, but a bunch of Mexicans, fifty or more, are headed this way to blow up the dam. I saw and heard them." "Where?" "At the spring a mile south. I was watching down there, where Atkinson had sent me after supper, relieving the man who kept lookout during the afternoon. That was where the booze was dealt out last night, you remember. I was sitting there when I heard a crowd coming. At first I thought it was our men, but when they stopped to drink and smoke, I saw by their talk they were Mexicans. But there was one white man with them, a leader. He and a Mexican talked in English. They're to raid the camp, crawling up the canyon, to dynamite the dam first, then fire the buildings." "Then they're on the road here now?" "Yes." The speaker licked his lips. "I cut along the hillside until I got ahead of them, but it was slow going in the dark and stumbling through the sage. They must be close at hand by this time, though I came faster than they did. The white man said to the Mexican that they wanted to reach the dam just at moonrise, and that will be pretty quick now." "Go to the bunk-house and call the men waiting there, and get a gun yourself," Weir ordered. "The storekeeper will give you one." When the messenger had darted out, he looked at the others. "You must take these girls away from here, doctor, at once." "But I don't go," Johnson snapped forth, drawing his revolver and giving the cylinder a spin. "I never could hit anything, and haven't had a firearm in my hand for years, but I can try," Pollock stated. "This promises to be interesting, very interesting." "Very," said Weir. For a little he stood in thought, while the others gazed at him without speaking. His straight body seemed to gather strength and power before their eyes, his clean-cut features to become hard and masterful.
