When he came to the surface, Bob’s first sensation was one of extreme weariness. So spent was he that it was all he could do to keep himself afloat. The possibility of another shot from Miguel did not spur him to in the water. If the shot was to come, it would. Bob knew that he was alive, therefore the danger which threatened the dam was over. This being the case, a great contentment came to him—what could happen to him now mattered very little.  
But as the minutes passed he got back his grasp on things and realized that no more shots were coming. Evidently the Mexican had become frightened and had run. The next thing he knew was that he was being pulled out of the water by Feather-in-the-Wind.
 
“Hurt?” said the Indian.
 
“No,” Bob . “Mig—Miguel got away!”
 
The redskin did not seem to bother about the Mexican’s escape. From the gentle way in which he handled the boy, it was clear that he was proud of him, proud that the young white man had done such a brave deed. He had seen what had happened as he came running back from the camp.
 
“No matter,” he said. “You save dam. I see. Good work.”
 
The praise acted like a on the weary boy. He stood up.
 
“We’d better hurry back,” he said, “and send someone after the Greaser. He’s dangerous.” And without further words the two set .
 
Under the moon the town lay quiet, only a lighted window here and there to tell that it was inhabited. Around the and on the dam itself tiny shadows moved to show that the watchmen were not sleeping. Just before they reached the Quarter-house, a horse and rider up the hill. Bob recognized Jenkins and stopped him.
 
“Did you get your men?”
 
“They dusted ’fore I got there,” was the disgusted answer. “I trailed ’em down stream but I reckon they’ve hit the border by now.”
 
“Sorry,” sympathized Bob, “but I guess they found I’d got out and that scared ’em.”
 
“I reckon so, ’cause they had too good a start for me to catch up with ’em. Good night to ye,” he finished and galloped off to put his tired horse away and get some much-needed rest for himself.
 
“Too bad,” the Indian as they walked on. “But you no tell him ’bout Miguel. Why not?”
 
“I think I’d better report to Big Boss first. Perhaps he will have some other plan.”
 
“Boss Whitney not here,” stated the Indian. “Boss Taylor good man but not like Chief. You wait for him. Now I go send one, two my young men trail Miguel. Perhaps they catch him—Jenkins, he never catch him. He tired. Not much good trail nohow.”
 
This sounded like good advice to Bob.
 
“Go ahead,” he said. “I’d like to see Miguel well punished.”
 
The Indian stalked swiftly away and Bob turned towards his boarding house and sleep. It seemed a safe bet that there would be no further trouble that night. In all probability if an uprising amongst the Mexican had been planned it would not come off to-night. Bob was sure that the blowing up of the dam would have been the signal for the starting of general . Since he had been able to prevent the signal being given, and at the same time had scared Miguel off, the chances were that all would remain quiet. Leaderless, the Mexicans were harmless, and Bob had a that Miguel was the only one of them who was strong enough to direct the revolt.
 
But a surprise awaited him when he pushed open the door of his room. Seated on the bed was Hoyt, who showed signs of having anxiously awaited him.
 
“At last! I thought you’d never show up.”
 
“What’s the rush?” asked Bob. “Found out something?”
 
“You bet I have. A whole heap. Bet it’ll make your hair curl—”
 
“Come on, Ted, old , out with it,” Bob urged the excited boy. “You haven’t said anything yet. You’ve up, now play something!”
 
“I—I think a bunch of Greasers are goin’ to raid the dam!”
 
“What?” Bob exploded. “Mexicans from the other side of the border?”
 
“Yes, I think so. Reg’lar bandits—about fifty of ’em.”
 
“How do you know?”
 
“I saw ’em. Dad sent me out ’bout sundown to hunt a stray and I saw some smoke coming from a draw where nobody had any business being. I my and crawled up until I could see.”
 
“And what did you see?”
 
“A bunch of armed Mexicans! They had camped for supper. I figgered that they were coming on up here to-night, so I beat it straight for you. Bet Dad’s got a search party out huntin’ me right now!”
 
“Gee whiz, but we’ll have to get busy in a hurry,” snapped Bob. “Come on, we’ll wake Mr. Taylor.”
 
He had turned towards the door as he was speaking and the words died in his throat as the door flew open and a dusty form stepped into the lighted room.
 
It was Jerry King!
 
“You?” gasped Bob. “You? What are you doing here? To tell us that the dirty work you started is successful?”
 
The boy stood straight under the his former friend heaped upon him. A little smile was at the corner of his mouth as he answered.
 
“You haven’t much faith in me, have you? You are quite ready to believe that I have been a to the Service.”
 
“But—but you are!” Bob, taken aback for a moment by Jerry’s words. “Didn’t you admit it—”
 
“Whatever I am, we haven’t got time to gas about it now. I came to—”
 
“I don’t care what you came for,” flashed Bob. “Don’t try to sell out the other side now! It’s bad enough as it is without your double-crossing your new friends!”
 
For a long moment both boys eyed each other without . Then in a flash Bob’s anger fled and he thought clearly. Jerry must not be let out to do more damage. He was too dangerous. He must be caught and put away until the crisis was over. No sooner had the thought flashed through his mind than he acted. Jerry was nearest the door, which was still open, so a leaping tackle was the only thing that would work.
 
Bob dived at his former chum with all his force. They grappled.
 
“At him, Ted! We’ve got to keep him!” he panted as he struggled with his .
 
Ted was so amazed by the sudden happening that he could not make his muscles respond to the call immediately. When he did get started it was too late, for Jerry had got an arm free and had swung his fist to Bob’s . The blow, while it did not knock the Eastern boy out, was sufficient to loosen his grasp and Jerry jerked away and flashed out of the room.
 
Ted went after him on a run but again he was too late, for when he reached the threshhold of the house, his had disappeared. Dashing back through the hall, he met Bob on his way out, and they went to the door.
 
“Lost him,” reported Ted. “Clumsy fool I am!”
 
“Don’t worry,” returned Bob. “I ought to have been able to hold him. I’m only worried about what he might do now. I’m going to wake Mr. Taylor.”
 
“No good do that,” a quiet voice came to them from right beside them in the shadow of the .
