"Just as you please, my dear boy," replied Bob, carelessly. "Just find a good place where you can see her when she shoots, and I'll drop the go-devil." Ralph lost no time in obeying the young moonlighter's instructions, seeking a refuge near the corner of a small tool-house to the windward of the well, and about a hundred yards from it. "Look out for your mouth and nose just after the explosion," cautioned George, "for the gases which will come first to the surface are very poisonous." "All ready!" shouted Bob, as he looked around to see that every one was in a safe position, and then approached the well with the go-devil in his hands. There was an instant's pause as the boy stood with the heavy iron poised over the aperture, and then dropping it, he sought shelter by the side of Ralph and George. Perfect silence reigned for what seemed a long time while the go-devil was falling through twelve hundred feet of oil and water; but the time was hardly more than a minute, and then Ralph, who had expected to hear a deafening noise, simply heard a crackling sound, much as if two small fire-crackers had been exploded. It had not occurred to him that but little could be heard from such a distance beneath the surface. "Look out for the gases!" cried George. And as Ralph covered his nose and mouth with his handkerchief, he could see a black vapor, almost like smoke, arising from the mouth of the well. "There is no oil there," he said to himself, as second after second went by and there was no appearance of anything save the gases of combustion. He was almost as disappointed as Mr. Hoxie would have been at finding a "dry well;" for after all his tedious waiting he hoped to have been rewarded by seeing the "shoot" of the oil. He was rather surprised that Bob's face showed no signs of disappointment, for he surely must have wanted to see oil after his dangerous work. But Bob simply looked expectant, with his gaze fixed on the mouth of the well, and Ralph turned again just in time to see a most wonderful sight. From out of the mouth of the well arose what appeared to be a solid column of greenish yellow, rising slowly in the air like one of the pillars of Aladdin's palace as it was formed by the genii. The top was rounded, and the sides of this marvelous column, held together only by some mighty force, shone in the moonlight like a polished surface of marble, while all the time it arose inch by inch without fret or check, until the top wavered in the night wind. Then one or two drops could be seen rolling off from the summit, and in an instant the entire appearance changed. With a mighty bound the oil leaped into the air, tearing asunder the summit of the derrick as if it had been of veriest gossamer, dashing the heavy timbers aside like feathers, and spouting in the pale light drops as of molten gold. For a radius of twenty feet around the well the air seemed filled with this liquid gold that was coming from the very bowels of the earth.
