Denis considered without moving a muscle. If he were armed he would creep on his belly like the snake itself and trust to his dexterity to strike the first blow. But he was not armed. He had no weapon of any sort; the one good weapon in the drive was fast in the nugget--ah! The nugget! He had forgotten it; the remembrance was like a glass of spirit. There behind him, within reach almost of his feet, was the only weapon worth thinking about--worth an effort--worth a risk. Very slowly, very laboriously, he crawled backward until his foot did touch the wooden haft of the driving-pick. The snake was still circling at the bottom of the shaft. Turning suddenly, seizing the haft with one hand, and the unburied end of the pick with the other, Denis twisted it as a gimlet, and had it out at one wrench. Simple though the expedient, it had only occurred to him as he crawled backward for his life. Now he was crawling forward again, feeling his way with the pick, his open knife between his teeth; and he crawled with less caution, savouring the fight. The pick rang against a stone. The snake was aroused. Its body writhed in angry knots and circles, still in the square of daylight, but now with tongue darting and eyes piercing into the mouth of the tunnel at each contortion. Denis felt its body was about to follow, made the rush himself on hands and knees, frightened the enemy by so doing, and next instant had its neck nailed to the ground at one lucky blow; but as he scrambled out its folds flew round his leg, crushing it horribly and irresistibly drawing it towards its head. The blood ran down Denis's chin as he plucked the open knife from his teeth. Then the strong blade sawed through the slimy body a foot below the head. But for long the headless coils wrung the slayer's leg, while the forked tongue played in and out of the bleeding remnant on the ground. At last he leaned lame but unencumbered against the side of the shaft. The sun was in the zenith; it lit the slabs on two sides half-way down. Denis knew the sunlight was there, though he could not lift his head to look on it again. He was sick, dizzy, and in pain; with more space or a less loathsome litter he would have stretched himself out where he was. As it was he hugged the slabs in a standing swoon until a voice came down to him from the mouth of the shaft. "Mister! Mister! Dent! Denis!" He reeled and raised a ghastly face. "What's the matter down there?" "Nothing; only I was nearly killed by a snake." "A snake!" "A carpet snake; but I killed it, thank God." "A carpet snake!" "Nearly eight feet long." "Why, there's one up here about the same size, must be its mate. That one must have fallen down. I've killed this one!" But the raised voice quavered; the lad was whimpering, shivering against the sky. Denis became himself. "Let down the bucket, Jimmy." "Oh! Oh! I haven't got the strength to draw you up, I know!" "What's happened--what else?"
