After Hopalong had ridden off on his desert trailing, Johnny and Red rode to the Question-Mark, reaching it a little after daylight and were promptly challenged when near the smaller corral. The sharp voice changed to a friendly tone when the sentry had a better look at the pair.

"Thought you'd be up with th' circus," said the Question-Mark puncher.

"On our way now," replied Johnny. "Come down here to learn what was happenin'. Meet Red Connors, an old friend of Waffles."

"Howd'y," grunted the puncher, looking at Red with a keener interest. "You fellers are lucky—we got to stay here an' miss it all. Walt come down last night an' said Kane's goin' to be a hard nut to crack. He's fixed up like a fort."

"Reckon we'll take a look at it," said Johnny, wheeling.

"Hey! If you want to find Mac, he's hangin' out at Quayle's."

Johnny waved his thanks and rode on with his cheerful companion. In due time they heard the distant firing and not much later rode up to Quayle's back door and went in. McCullough was raging at the effectiveness of the sharpshooters on Kane's roof who had succeeded in keeping the fight at long range and who dominated certain strategic positions which the trail-boss earnestly desired to make use of; all of which made him irritable and unusually gruff.

"Where you been?" he demanded as Johnny entered.

"Locatin' a missin' herd of yore cattle," retorted Johnny, nettled by the tone. "They're waitin' for you when you get time to go after 'em. Now we'll locate them sharpshooters. Anythin' else you can't do, let us know. Come on, Red," and he went out again, his grinning friend at his heels. At the door Red checked him.

"Looks like a long-range job, Kid. My gun's all right for closer work, but I ought to have a Sharp's for this game."

Johnny wheeled and went back. "Gimme a Sharp's," he demanded.

"Take Wilson's—they got him yesterday," growled the trail-boss, pointing.

Johnny took the gun and the cartridge belt hanging on it, joined Red and led the way to a place he had in mind. Reaching the selected spot, an adobe hut on the remote outskirts of the sprawled town, he stopped. "This is good enough for me," he grunted, "except th' range is too cussed long. Well, we'll try it from here, anyhow."

"I'm goin' to th' next shack," replied Red, moving on. "We'll use our old follow-shootin'—an' make 'em sick. Ready? I'm goin' to cross th' open." At his friend's affirmative grunt Red leaned over and dashed for the other adobe. A bullet whined in front of him, barely heard above the roar of Johnny's rifle. He settled down, adjusted the sights and proceeded to prove title to his widely known reputation on other ranges of being the best rifle-shot of many square miles. "Make a hit, Kid?" he called. "It's mebby further than you figger."

"It is," answered Johnny. "Like old times, huh? Lord help 'em when you get started! Are you all set? I'm ready to draw 'em."

"Wind gentle, from th' east," mumbled Red. "Dirty gun—got to shoot higher. All right," he called, nestling the heavy stock.

Johnny pushed his rifle around the corner of the building, aimed quickly and fired. A hatted head arose above Kane's roof and a puff of smoke spurted into the air above it as Red's Sharp's roared. The hat flew backward and the head ducked down again, its owner surprised by the luck of the shot.

Johnny laughed outright. "For a trial shot I'm admittin' that was a whizzer. I ain't no slouch with a Sharp's—but how th' devil you can make one behave like you do is a puzzle to me."

"I'm still starin'," said a humorous, envious voice behind them and they looked around to see Waffles hugging the end of the building. "If I can get over on Red's right I'll help make targets for him."

"Walk right over to that other shack," called Johnny. "Yo're safe as if you was home in yore bunk. Cover him, Red."

Waffles' mind flashed back into the past and what it presented to him greatly reassured him, but to walk was tempting Providence; he ran across the open and again Red's rifle roared.

"Got him!" yelled Johnny, staring at the body lying over the distant parapet. It was swiftly pulled back out of sight. The rest of Johnny's words were profanely eulogistic.

"Shut yore face," growled Red. "It was plumb luck."

"Shore it was," laughed his friend in joyous irony; "but yo're allus makin' 'em. That's what counts."

Waffles, having gained the shelter he coveted, looked around. "Heads was plentiful up there yesterday. There was allus one or two bobbin' up. I'm bettin' they'll be scarcer today."

"They'll be scarcer tomorrow, when we are behind them other shacks," replied Red. "They're easy three hundred paces nearer, an' that's a lot sometimes."

"An' twice as much to them," rejoined Johnny. "Th' nearer you get th' more you make it even terms. You stay where you are—me an' Waffles'll go out there tonight."

When the afternoon dragged to an end Red had another sharpshooter to his credit, and the dominating group on the roof were much less dominant. They cursed the long-range genius who shot hats off of heads, clipped ears, and had killed two men. The shooting, with a rest and plenty of time to aim, would have been creditable enough; but to hit a bobbing head meant quick handling. They were properly indignant, for it was a toss-up with Death to show enough of their heads to sight a slanting rifle. One of their number, whose mangled ear was bound up with a generous amount of bandage, savagely hammered the chisel with which he was cutting a loophole through four inches of seasoned wood, vowing vengeance on the man who had ruined his looks.

The light failing for close shooting, the three friends left their positions and went to the hotel for a late supper, Red receiving envious, grinning looks as he entered the dining-room. Idaho promptly forsook his bosom friends and went over to finish his meal at the table of the newcomers.

"We got Red Frank's place plumb full of holes—you can see daylight through th' second floor," he announced; "but it don't seem to do no good. If I could get close enough to use a bomb I got, we might clean 'em up."

"Crawl up in th' dark," suggested Waffles.

"Can't; they spread flour all around th' place, an' th' minute a man crosses it he shows up plain. Two of us found out all about that!"

"Go through or over th' buildin's this side of th' place," said Johnny, visualizing the street. "They lead up close to Red Frank's."

Idaho stared, and slapped his thigh in enthusiastic endorsement. "I reckon you called it!" he gloated. "Wait till I tell th' boys," and he hastened back to his friends. Judging from the sudden noise coming from the table, his friends were of the same opinion and, bolting the rest of the meal, they hastened away to forthwith try the plan.

McCullough entered the dining-room and strode straight to Johnny. "Did I hear you say you know where my cattle are?" he asked, sitting down.

Johnny nodded, chewed hurriedly and replied. "I didn't finish it. I don't know where they are, but Hopalong is trailin' 'em, an' he'll know when he comes back. Pay us them rewards now, instead of later, an' I'll do some high an' mighty guessin' about yore head—an' bet you th' rewards that I guess right."

The trail-boss laughed. "You've shore got plenty of nerve," he retorted. "When this fight is over there won't be no rewards paid. We got th' whole gang in them two buildin's, an' we got 'em good. You've had yore trouble for nothin', Nelson."

"How 'bout th' gang that are with th' herd?" asked Johnny, a note of anger edging his words.

McCullough shrugged his shoulders. "I ain't worryin' about them—they'll never come back to Mesquite."

"That so?" queried Johnny, sarcastically. "I ought to keep my mouth shut, th' way yo're talkin', but I hate to see good men killed. I'll bet you they'll come back just at dawn, some time in th' next five days. An' I'll bet you they'll sneak up on this hotel an' raise th' devil, while Kane starts a bunch from his place and Red Frank's, to help 'em. Th' minute they start shootin' in here their friends'll sortie out an' carry th' fight to you. Want to bet on it?"

McCullough regarded the speaker through narrowed lids. "How do you figger that?" he demanded suspiciously. "You gettin' that out of yore medicine bag, too?" and then he eagerly drank in every word of the explanation. After a moment's thought he looked around the room and then back to the smiling Johnny. "Much obliged, Nelson. I'm beginnin' to see that I owe you fellers somethin', after all. If them fellers we want were loose an' you got 'em, then of course th' reward would stand; but you can't win it very well when we've got 'em corraled. Who-all is in that bunch with th' herd?"

Johnny smiled but shook his head.

"Didn't you say you knowed who killed Ridley?" persisted the trail-boss.

"I know him, an' how he did it. Hopalong saw him while his gun was smokin', but didn't know what he had shot at till later."

"Why didn't you tell me, an' earn that reward right away?"

"That's only half of th' rewards," replied Johnny. "There's money up for th' fellers that robbed th' bank. If we got Ridley's murderer th' others might 'a' smelled out what we was after. You see, I was robbed of more than eleven hundred dollars th' first night I was in town. Th' money belonged to th' ranch. Th' only chance I had of gettin' it back was to make th' rewards big enough to stand three splits that would be large enough to cover it. An' I'm still goin' to do that, Mac. Pay it now an' we'll stick with you till you get th' men an' yore herd. Of course, yo're going to get th' herd, anyhow, as far as we are concerned. I ain't holdin' that over yore head; I'm only tryin' to show you why I can't be open an' free with you."

"I couldn't pay th' rewards now even if I wanted to," said the trail-boss.

"I know that, an' I didn't think you would. I was only showin' you how things are with us."

McCullough nodded, placed a hand on the speaker's shoulder and arose, turning to Red. "Connors," he said, "yo're a howlin' wonder with a Sharp's. Much obliged for holdin' down that roof. If you can clean 'em up there this fight'll go on a cussed sight faster. Th' cover on th' north side of Kane's is so poor that we can't do much out there, but we can do a little better when them sharpshooters are driven down. From what I know of you two, yore friend Cassidy is shore able to trail that herd. I've quit worryin' about everythin' but th' fight here in town. An' lemme make a long speech a little longer: If you fellers can earn them rewards I won't waste no time in payin' up; but there ain't a chance for you. We got 'em under our guns."

"Who was right about where that raid on you was goin' to take place?" asked Johnny. "You was purty shore about that, too, wasn't you?"

The trail-boss smiled and shook his head. "Yo're a good guesser," he admitted, and went out to consult with Lukins.

The next day found the line a little tighter around the stronghold, thanks to Red's shooting, which increased in accuracy after he had decided to use closer cover and cut three hundred paces out of the range. Better positions had been gained by the attackers during the night, some of the more daring men now being not far from point-blank range, which enabled them to make the use of Kane's loopholes hazardous. To the north another rifleman lay in a hollow of the sandy plain, but too far away to do much damage. The north parapet of the building was hidden from Red by the one on the south and the aerial marksmen made free use of it.

Red Frank's place was in jeopardy, for Idaho and his enthusiastic companions were in the building next on the south, separated from the Mexican's house by less than twenty feet. There was an open window facing the gambling-house and Idaho, chancing quick glances through it, noticed that one of the heavy, board shutters of a window of the upper floor sagged out a little from the top. Signaling the men behind the jail to increase their fire, he coiled his rope and cast it through the window. It struck the upper edge of the shutter, dropped behind it and grew swiftly taut. Two of his companions added their strength to his, while the other two covered them by pouring a heavy revolver fire at the two threatening loopholes. The shutter creaked, twisted, and then slowly gave way, finally breaking the lower hinge and sailing over against the other house to a cheer from the jail. Heavy firing came through the uncovered window, the bullets passing through the opposing wall and driving the Diamond L men to other shelter. Here they waited until it died down and then, picking up the bomb made by the owner of the new freight wagon, Idaho lit the jumpy, uncertain fuse, waited as long as he dared and hurled it across the intervening space and through the shutterless window as the opening was being boarded up. There was a roar, jets of smoke spurt from windows and holes and the wild cursing of injured men rang out loudly. A tongue of flame leaped through a trapdoor on the roof and grew rapidly brighter. At intervals the smoke pouring up became suddenly heavy and thick, but cleared quickly between the onslaughts of the water buckets. Fire now crept through the side of the frame structure and mounted rapidly, and such a hail of lead poured through the smoke-spurting, upper loopholes that it became impossible for the buckets to be properly used. It was only a matter of time before the blazing roof and floor would fall on the defenders in the adobe-walled structure below, and through a loophole Red Frank suddenly shoved out a soiled towel fastened on the end of a rifle barrel.

"Come ahead, with yore hands up!" shouted a stentorian voice from the jail. "Quit firin', boys; they're surrenderin'." Almost on the tail of his words a hurrying line of choking Mexicans, bearing their wounded, streamed from the front door. They were promptly and proudly escorted by the hilarious attackers to safe quarters on the southern outskirts of the town.
