Neither saw the other until she stood directly in front of the excavation. He was lighting his pipe, his back towards her; she, thinking him to be about to leave the mine on his descent to the cabin, gayly called out: "What's your hurry?" Not dreaming of her dangerous proximity to the tunnel's mouth, he turned slowly, for the wind was fairly strong and he had not as yet secured a satisfactory light. He was about forty yards away. For one nerve-paralyzing second he was incapable of motion or speech. Then the pipe clattered on the slide-rocks and he was leaping like a cougar over the treacherous footing, a great cry bursting hoarsely from his white lips: "Run! For God's sake, run! Away from the tunnel!" Dazed by the awful fear in his voice, and misinterpreting the only two distinct words of his otherwise inarticulate command: "Run" and "Tunnel," she bolted obediently into the yawning mouth of the excavation. For a few seconds, with eyes blinded by the sudden transition from sun-glare to comparative darkness, she did not perceive the spluttering flare of the fuse. Then all at once came comprehension and in the shock of it she was as a marble statue. Paralyzed with horror at the awful death hissing there a scant five feet away, she seemed rooted to the ground; for the life of her she could not move hand or foot, standing numbly there waiting for the end. Each second seemed an eternity before his coming. His coming--to what? To share the horrible death that menaced her? She found her voice in one agonized scream of warning, but even as it left her lips he came dashing into the tunnel, shouting incoherent blasphemies and holding out both arms. A pile of litter on the floor of the tunnel entrapped his foot. A treacherous stone turned beneath his flying tread, and wildly striving to regain his balance, he pitched forward to her feet, striking his head on the rocks. He lay very still, a thin stream of blood trickling down his forehead. As a tigress protects her young, so did she cast her body between him and the fiery serpent hissing on the rock, her one thought being for his preservation. As she crouched above him there came vaguely into her mind the remembrance of a story told her in the long ago by her father, the story of a man who had saved his comrade by the plucking out of the burning fuse from a blast which was on the point of killing the man caught beneath some falling timbers. The details came painfully slow to her dazed mind and over there the fuse was hissing ominously. Suddenly it was all clear to her and unhesitatingly she sprang to the shelf and clutched the smoking terror with both hands. One frantic tug and the deadly dynamite was dangling before her; with the swiftness of a swallow she reached the mouth of the tunnel and, summoning all her strength for one mighty effort, cast it far down the mountain side. Then she turned unsteadily and slowly groped her way, like one who is blind, to the silent figure on the tunnel floor.
