Johnny rode up to the hotel, got a Winchester and ammunition for it from the stack of guns in the kitchen and then went to the stable for Red's horse and Pepper. As he led them out he stopped to answer a pertinent question from the upper window of the hotel and rode off again, leading the extra mounts.

Ed Doane lowered the rifle and scratched his head. "Goin' for a moonlight ride," he repeated in disgust as he drew back from the window. "Cussed if punchers ain't gettin' more locoed every day. Moonlight ride! Shore—go out an' look at th' scenery. Looks different in th' moonlight—bah! To me a pancake looks like a pancake by kerosene, daylight, wood fire or—or moonlight. I suppose th' moonlight'll get into 'em an' they'll be singin' love-songs an' harmonizin'; but thank th' Lord I don't have to go along!" He glanced around at a sudden thap! grinned in the darkness at the double planking on that side wall and sat down again. "Shoot!" he growled. "Shoot twice! Shoot an' be d—d! Waste 'em! Reckon th' moonlight's got into you, you cow-stealin', murderin' pup." Filling his pipe he packed and lit it, blew several clouds through nose and mouth and scratched his head again. "Goin' for a moonlight ride, huh? Well, mebby you are, Johnny, my lad; but Ed Doane's bettin' there's more'n a ride in it. You didn't go for no moonlight rides before that missin' friend of yourn turned up; an' then, right away, you ride up on one hoss, collect two more an' go gallivantin' off under th' moon. I'm guessin' close. Eddie Doane, I'll bet you a tenspot them three grizzlies are out for to put their ropes on them rewards. An' I hope they collect, cussed if I don't. That Scotch trail-boss is puttin' on too many airs for me—an' he's rilin' Nelson slow but shore. Go get it, Bar-20: I'm bettin' on you."

There came steps to his door. "Ar-re ye there, Ed?" called a voice.

"Shore; come in, Murphy."

The door opened and closed as the cook entered. "Have ye a pipeful? Mine's all gone."

"Help yourself," answered Doane, tossing the sack. "There it is, by yore County Cork feet."

"I have ut," grunted Murphy. "An' who was th' lad ye was talkin' to from th' windy just now?"

"Nelson. He's goin' ridin' in th' moonlight. Must aim to go far, for he's got three horses."

"Has he, now?" Murphy puffed in quiet satisfaction for a moment. "He's a good la-ad, Ed. Goin' ridin', is he? Well, ridin' is fine for them as likes it. But I'm wonderin' what he's doin' with th' kerosene I gave him?"

"Kerosene? When?"

"Whin he come in with his friend Cassidy—an' a fine bye that man is, too. Shure: a hull canteen av it. Two gallons. He says for me to kape it quiet: as if I'd be tellin'! Quayle would have me scalp if he knowed it—givin' away his ile like that. Now where ye goin' so fast?"

"For a walk, under th' moonlight!" answered Doane. "Yo're goin', too an' we're goin' with our mouths shut. Not a word about th' hosses or th' kerosene. You remember what Cassidy said about goin' agin' Kane's northeast corner? Come on—an' see th' bonfire!"

"Shure, an' who's fool enough to have anny bonfires now?"

"Murphy, I said with our mouths shut. Come on, up near th' jail!"

The cook scratched his head and favored his companion with a sidewise glance, which revealed nothing because of the darkness of the room. "Th' jail?" he muttered. "He's crazy, he is. Th' jail won't make no bonfire. It's mud. But as long as he has th' 'baccy, I'll go wid him. Whist!" he exclaimed as another thap! sounded on the wall. "An' what's that?"

"This room's haunted," explained Ed.

"Lead th' way, thin; or let me," said Murphy in great haste. "I'll watch yore mud bonfire."

After leaving the hotel Johnny kept it between himself and Kane's building, rode to the arroyo which Roberts had found so useful and followed it until out of sight of anyone in town. When he left it he turned east, crossed the main trail and dismounted east of the place where he and Red had kept watch on the gambling-house roof. Working his way on foot to his sharpshooting friends he lay down at Red's side and commented casually on several subjects, finally nudging the Bar-20 rifleman.

"I'm growin' tired of this spot an' this game," he grumbled. "They know where we are now, an' that roof's plumb tame."

Red stirred restlessly. "You must 'a' read my mind," he observed. "You've had a spell off—stay here while I take a rest."

"Stay nothin'!" retorted Johnny. "This ain't our fight, anyhow."

"Somebody's got to stay," objected Red.

"Let Waffles, then," rejoined Johnny. "You don't care if we look around?"

"I'd just as soon stay here as go any place else," said the ex-foreman of the O-Bar-O. "Where you fellers aimin' to go?"

"Over west to cover Hoppy," answered Johnny, remembering that this much was generally known. "He aims to make a dash for th' hotel, an' he's so stubborn nobody can stop him. He says th' fight's been goin' on too long; an' you know how he can use six-guns. To use 'em right he'll have to get plumb close."

"Cussed fool!" snorted Red, arising to his knees. "How can he end it by makin' a dash, an' usin' his short guns? Mebby he's aimin' to put his rope on it an' pull it over, shootin' as they pop out from under!" he sarcastically suggested.

"Mebby; better ask him," replied Johnny. "I did. Mebby you can get it out of him. When he wants to keep his mouth shut, he shore can keep it shut tight. There's no use wastin' our breath on it. He's got some fool scheme in his head an' he's set solid. All we can do is to try to save his fool skin. Waffles can hold down this place till we come back. Come on, Red."

Red grumbled and stretched. "All right. See you later mebby, Waffles."

Johnny turned. "Don't forget an' shoot at th' feller runnin' for th' east end of th' buildin'," he warned.

"Mac sent th' word along a couple of hours ago," replied Waffles, settling down in the place vacated by Red to resume the watch on the hotel roof, which was fairly well revealed at times by the moon. He seemed to be turning something over in his mind, but finally shrugged his shoulders and gave his attention to the roof. "They've got somethin' better'n six-guns at close range," he muttered. "Well, a man owes his friends somethin', so I'm holdin' my tongue."

Reaching the horses Johnny and his companion mounted and rode northward, leading the spare mount.

"What's he up to?" demanded Red.

"Goin' to set fire to th' shack," answered Johnny, and he forthwith explained the whole affair.

"Huh!" grunted Red. "There ain't no doubt in my mind that it'll work if he can get there an' get th' fire started." He was silent for a moment and then pulled his hat more firmly down on his head. "If he don't get there, I'll give it a whirl. Anyhow, I'd have to leave cover to get to him if he went down so it ain't much worse goin' th' rest of th' way. An' I'm tellin' you this: That lone loophole is shore goin' to be bad medicine for anybody tryin' to use it after he starts. I'll put 'em through it so fast they'll be crowdin' each other."

"An' while yo're reloadin' I'll keep 'em goin'," said Johnny, patting his borrowed Winchester. "They'll shore think somebody's squirtin' 'em out of a hose."

Some time later he stopped his horse and peered around in the faint light.

Red stopped, also. "This th' place?"

"Looks like it—we ought to get some sign of Hoppy purty soon. Anyhow, we'll wait awhile. Glad that moon ain't very bright."

"An' cussed glad for th' clouds," added Red. "Clouds like them ain't th' rule in this part of the country." He leaned over and looked down at the sand. "Tracks, Kid," he said. "Follow 'em?"

"No," answered his companion slowly. "I'm bettin' they're Hoppy's. Stay with th' cayuses—I'm goin' to look around," and as he dismounted they heard a hail. Red swung to the ground as their friend appeared.

"You made good time," said Hopalong, advancing. "I been off lookin' things over. We can leave th' cayuses in a little hollow about long rifle-shot from th' buildin'. From there you two can get real close by travelin' on yore bellies from bush to bush. Th' cover's no good in day light, but on a night like this, by waitin' for th' clouds, it'll be plenty good enough."

"How close did you get?" asked Johnny.

"Close enough to send every shot through that loophole, if I wanted to."

"Did they see you? Did you draw a shot?"

"No. They ain't watchin' that loophole very close. Ain't had no reason to since th' stables burned. There ain't nobody been layin' off in this direction. Th' cover wasn't good enough to risk it, with only a blank wall to watch, an' with them fellers on th' roof to shoot down. Red couldn't cover th' north part of it from where he was. I been wonderin' if I ought to use a cayuse at all."

"There's argument agin' usin' one," mused Johnny.

"Th' noise, an' a bigger object to catch attention," remarked Red. "If you walked th' cayuse to soften its steps, it still looms up purty big; an' if you cut loose an' dash in, th' noise shore will bring a shot. Me an' th' Kid would have to start shootin' early an' keep it up a long while—an' we're near certain to leave gaps in th' string."

"What moonlight there is shines on this end of th' buildin'," observed Johnny. "That loophole show up plain?" he asked.

"You can't see nothin' else," chuckled Hopalong. "It's so black it fair hollers."

Red drew the Winchester from its sheath and turned the front sight on its pivot, which then showed a thin white line. He never had regretted having it made, for since it had been put on he had not suffered the annoyance of losing sight of it against a dark target in poor light. "Bein' bull-headed," he remarked, "you chumps has to guess; but little Reddie ain't doin' none of it. I told you long ago to have one put on."

"Shut up!" growled Johnny, turning his own Winchester over in his hands.

"I reckon I'm travelin' flat on my stomach," said Hopalong, slinging the big canteen over his head. "I'll go with you till we has to stop, let you get set an' then make a run for it. Seein' that th' Kid has got a repeater, too, you'll be able to keep lead flyin' most of th' time I'm in th' open if you don't pull too fast; an' when you run out of cartridges I'll start with my Colts. I'll be close enough, then, to use 'em right. When you see that I'm under th' buildin' go back quite a ways so th' fire won't show you up too plain, an' watch th' roof. I'll start a fire under that loophole before I leave, an' that'll spoil their view through it; an' I ain't leavin' before I've fixed things so them fellers will have so much to do they won't have much time for sharpshootin'. That buildin' will burn like a pine knot."

"Then yo're comin' back th' way you go in?" asked Red.

"Shore," answered Hopalong. "Everythin' plain?"

"Watch me," ordered Red, his hand rising and falling. "If we space our shots like this we ought to be able to reload while th' other is emptyin' his gun. Is it too slow?"

"No," said Johnny, considering.

"No," said the man with the canteen, watching closely. "It'll take that long to throw a gun into th' loophole an' line it up, in this light."

"Not bein' used to a repeater like Red is," suggested Johnny, "I'd better shoot th' second string—that'll give us three of 'em before it's my time to reload. Red can slide 'em in as fast as I can shoot 'em out, timin' 'em like that."

"You can put 'em through that hole as good as I can," said Red. "It's near point-blank shootin'. You do th' shootin' an' I'll take care of loadin' both guns. We can't make no blunders, with Hoppy out there runnin' for his life."

"That's why I ought to do th' runnin'," growled Johnny. "I can make three feet to his two."

"It's all settled," said Hopalong, decisively. "I got th' kerosene, an' I'm keepin' it. Come on. No more talkin'."

They followed him over the course he had picked out and with a caution which steadily increased as they advanced until at length they went ahead only when the crescent moon was obscured by drifting clouds. Ahead loomed the two-story gambling-hall, its windowless rear wall of bleached lumber leaden in the faint light. An occasional finger of fire stabbed from its south wall to be answered by fainter stabs from the open, the reports flat and echoless. A distant voice sang a fragment of song and a softened laugh replied to a ribald jest. A horse neighed and out of the north came quaveringly the faint howl of a moon-worshiping coyote.

The three friends, face down on the sand, now each behind a squat bush, wriggled forward silently but swiftly, and gained new and nearer cover. Again a cloud passed before the moon and again they wriggled forward, their eyes fixed on the top of the roof ahead, two of them heading for the same bush and the other for a shallow gully. The pair met and settled themselves to their satisfaction, heads close together as they consulted about the proper setting of the rear sights. One of them knelt, the rifle at his shoulder reaching out over the top of the bush, his companion sitting cross-legged at his side, a pile of dull brass cartridges in the sombrero on the ground between his knees to keep the grease on the bullets free from sand.

The kneeling man bent his head and let his cheek press against the stock of the heavy weapon, whispered a single word and waited. Twice there came the squeak of a frightened rat from his companion and instantly from the right came an answering squeak as the figure of a man leaped up from the gully and sprinted for the lead-colored wall, the heavy, jarring crash of a Winchester roaring from the bush, to be repeated at close intervals which were as regular as the swing of a pendulum. A round, dark object popped up over the flat roof line and the cross-legged man on the ground threw a gun to his shoulder and fired, almost in one motion. The head dropped from sight as the marksman slid another cartridge into the magazine and waited, ready to shoot again or to exchange weapons with his kneeling friend.

The runner leaped on at top speed, but he automatically counted the reports behind him and a smile flashed over his face when the count told him that the second rifle was being used. He would have known it in no other way, for the spacing of the shots had not varied. Again the count told of the second change and a moment later another extra report confirmed his belief that the roof was being closely watched by his friends. A muffled shout came from the building and a spurt of fire flashed from the loophole, but toward the sky and he fancied he heard the sound of a falling body. Far to his left jets of flame winked along a straggling line, the reports at times bunched until they sounded like a short tattoo, while behind him the regular crashing of an unceasing Winchester grew steadily more distant and flatter.

His breath was coming in gulps now for he had set himself a pace out of keeping with the habits of years and the treacherous sand made running a punishment. During the last hundred feet it was indeed well for him that Johnny shot fast and true, that the five-hundred grain bullets which now sang over his aching head were going straight to the mark. He suddenly, vaguely realized that he heard wrangling voices and then he threw himself down onto the sand and rolled and clawed under the building, safe for the time.

Gradually the jumble of footsteps over his head impressed themselves upon him and he mechanically drew a Colt as he raised his head from the earth. Suddenly the roaring steps all went one way, which instantly aroused his suspicions, and he crawled hurriedly to the black darkness of a pile of sand near the bottom of the south wall, which he reached as the steps ceased. No longer silhouetted against the faint light of the open ground around the building, a light which was bright by contrast with the darkness under the floor, he placed the canteen on the ground and felt for chips and odds and ends of wood with one hand while the other held a ready gun.

There came the sharp, plaintive squeaking of seldom-used hinges, which continued for nearly a minute and then a few unclassified noises. They were followed by the head of a brave man, plainly silhouetted against the open sand. It turned slowly this way and that and then became still.

"See anythin'?" came a hoarse whisper through the open trap.

There was no reply from the hanging head, but if thoughts could have killed, the curious whisperer would have astonished St. Peter by his jack-in-the-box appearance before the Gates.

"If he did, we'd know by now, you fool," whispered another, who instantly would have furnished St. Peter with another shock.

"He'd more likely feel somethin', rather than see it," snickered a third, who thereupon had a thrashing coming his way, but did not know it as yet.

The head popped back into the darkness above it, the trapdoor fell with a bang, and sudden stamping was followed by the fall of a heavy body. Furious, high-pitched cursing roared in the room above until lost in a bedlam of stamping feet and shouting voices.

"He ought to kill them three fools," growled Hopalong, indignant for the moment; and then he shook with silent laughter. Wiping his eyes, he fell to gathering more wood for his fire, careless as to noise in view of the free-for-all going on over his head. Removing the plug from the canteen he poured part of the oil over the piled-up wood, on posts, along beams and then, saturating his neckerchief, he rubbed it over the floor boards. Wriggling around the pile of sand he wet the outer wall as far up as his arm would reach, soaked two more posts and another pile of shavings and chips and then, corking the nearly empty vessel, he felt for a match with his left hand, which was comparatively free from the kerosene, struck it on his heel and touched it here and there, and a rattling volley from the besiegers answered the flaming signal. Backing under the floor he touched the other pile and wriggled to the wall directly under the loophole. Again and again the canteen soaked the kerchief and the kerchief spread the oil, again a pile of shavings leaned against a wetted post, and another match leaped from a mere spot of fire into a climbing sheet of flame, which swept up over the loophole and made it useless. As he turned to watch the now well-lighted trapdoor, there came from the east, barely audible above the sudden roaring of the flame, the reports of the rifles of his two friends, the irregular timing of the shots leading him to think that they were shooting at animated targets, perhaps on the roof.

The trapdoor went up swiftly and he fired at the head of a man who looked through it. The toppling body was grabbed and pulled back and the door fell with a slam which shook the building. Hopalong's position was now too hot for comfort and getting more dangerous every second and with a final glance at the closed trapdoor he scrambled from under the building, slapped sparks from his neck and shoulders and sprinted toward his waiting, anxious friends, where a rifle automatically began the timed firing again, although there now was no need for it. Slowing as he left the building further and further behind he soon dropped into a walk and the rifle grew silent.

"Here we are," called Johnny's cheery voice. "I'm admittin' you did a good job!"

"An' I'm sayin' you did a good one," replied Hopalong. "Them shots came as reg'lar as th' tickin' of a clock."

"Quite some slower," said Red. "That gang can't stay in there much longer. Notice how Mac's firin' has died down?"

"They're waitin' for 'em to come out an' surrender," chuckled Hopalong. "Keep a sharp watch an' you'll see 'em come out an' make a run for it."

"Better get back to th' cayuses, an' be ready to foller," suggested Red.

"No," said Johnny. "Let 'em get a good start. If we stop 'em here Mac may get a chance to cut in."

"An' we'll mebby have to kill some of th' men we want alive," said Hopalong. "Let 'em get to that valley an' think they're safe. We can catch 'em asleep th' first night."

The gambling-hall was a towering mass of flames on the south and east walls and they were eating rapidly along the other two sides. Suddenly a hurrying line of men emerged from the north door of the doomed structure, carrying wounded companions to places of safety from the flames. Dumping these unfortunates on the ground, the line charged back into the building again and soon appeared leading blind-folded horses, which bit and kicked and struggled, and turned the line into a fighting turmoil. The few shots coming from the front of the building increased suddenly as McCullough led a running group of his men to cover the north wall. A few horses and a man or two dropped under the leaden hail, the accuracy of which suffered severely from the shortness of breath of the marksmen. The group expanded, grew close at one place and with quirts rising and falling, dashed from the building, pressing closely upon the four leaders, and became rapidly smaller before the steadying rifles of its enemies took much heavier toll. Before it had passed beyond the space lighted by the great fire only four men remained mounted, and these were swiftly swallowed up by the dim light on the outer plain.

McCullough and most of his constantly growing force left cover and charged toward the building to make certain that no more of their enemies escaped, while the rest of his men hurried back to get horses and form a pursuing party.
