Meanwhile, the work of destruction went swiftly forward, explosions following in quick succession and with terrific force, throughout the Yankee group of mines, and the adjoining claims; while the flames from the burning shafts were rivaled by those which spread from the mills to the shops, storehouses and stables, and finally, to the miners' quarters, till all were speedily reduced to ashes. Around the entrance to tunnel No. 3, a large crowd had gathered, not only from the various mines, but also from neighboring mining camps, all anxiously awaiting the return of the rescue party. At last they appeared. The first to emerge into daylight, was Ned Rutherford, bearing in his arms the crushed and mutilated form of little Bull-dog. Behind him came Houston, partially supported by one of the young miners and by Lyle, his left arm hanging at his side, his face deathly white beneath the blood and grime, but firm and dauntless as ever. As he stepped forth into the light, a wild cheer rose on the air, but Houston, raising his right hand with a deprecatory motion, silently pointed backward toward the tunnel, where, slowly emerging into view of the crowd, were Morton Rutherford and Mike, carrying, with the assistance of the other miner, the bleeding and unconscious form of Jack. The cheers were hushed, and the crowd silently surged about Houston and the two motionless, unconscious forms laid side by side upon the ground, their heads pillowed upon the rough jackets of the men, folded and tenderly placed beneath them by the hands of Lyle and Leslie, the latter half fainting with excitement. The men crowding about Houston congratulated him with a hearty hand-clasp, unaccompanied by words, except for an occasional inquiry as to his own condition. "I am all right," he said in reply to the latter, "my arm is nothing, the merest trifle; my only thought is for the two lives which I fear have been sacrificed for mine." Anxiously he bent above the prostrate forms. Jack's head was frightfully gashed, and his heavy, labored breathing indicated that his brain was already affected. Houston spoke a word to Morton Rutherford, who quickly withdrew, and taking the swiftest horse in camp, was soon speeding down the road to the Y, in a second race against death. Houston next knelt beside Bull-dog; a faint fluttering about the heart was the only sign of life. The little waif was well known among the mining camps of that vicinity, and there were few dry eyes in the crowd as Houston told the story of his heroism.
