Indeed, the outer wall of the barn, nearest the door, was wavering in a great section and slowly tottering in. Another moment or two it would crash to the floor and block the way of Dan Barry, coming out, with a flaming ruin. Next the watchers saw a struggle among the group which watched. Three men were struggling with Buck Daniels, but presently he wrenched his arms free, struck down two men before him with swinging blows of his fists, and leaped into the smoke. "He's gone nutty, like a crazy hoss with the sight of the fire," said Mac Strann quietly. "He ain't! He ain't!" cried Haw-Haw Langley, wild with excitement. "He's holdin' back the burnin' wall to keep the way clear, damn him!" Indeed, the tottering wall, not having leaned to a great angle, was now pushed back by some power from the inside of the barn and kept erect. Though now and again it swayed in, as though the strength which held it was faltering under the strain. Now the eyes of the watchers were called to the other end of the barn by a tremendous crashing. The entire section of that part of the roof fell in, and a shower of sparks leaped up into the heart of the sky, lighting the distant hills and drawing them near like watchers of the horror of the night. "That's the end," said Mac Strann. "Haw-Haw, they wasn't any good in your prayer." "I ain't a professional prayin' man," answered Haw-Haw defensively, "but I done my best. If----" He was cut short by a chorused cry from the watchers near the door of the barn, and then, through the vomitted smoke and the fire, leaped the unsaddled body of Satan bearing on his back the crouched figure of Dan Barry, and in the arms of Barry, limp, his head hanging down loosely, was the body of the great black dog, Bart. A fearful picture. The smoke swept following around the black stallion, and a great tongue of flame licked hungrily after the trio. But the stallion stood with head erect, and ears flattened, pawing the ground. With that cloud of destruction blowing him he stood like the charger which the last survivor might ride through the ruin of the universe in the Twilight of the Gods. At the same instant, another smoke-clad figure lunged from the door of the barn, his hands outstretched as though he felt and fumbled his way through utter darkness. It was Buck Daniels, and as he cleared the door the section of tottering wall which he had upheld to keep the way clear for the Three, wavered, sagged, and then sank in thunder to the floor, and the whole barn lay a flame-tossed mass of ruin. The watchers had scattered before the plunge of Satan, but he came to a sliding halt, as if his rider had borne heavily back upon the reins. Barry slipped from the stallion's back with the wounded dog, and kneeled above the limp figure. "It ain't the end," growled Mac Strann, "that hoss will go runnin' back into the fire. It ain't hoss nature to keep from goin' mad at the sight of a fire!"
