But there was no joshing now; this was a time for breaking records. There was a big cement block for the engine, and a wooden block on top of that, to take up the vibration; and now the truck with the engine on was backed into place, and blocked firm, and the skids made solid, and in a jiffy the engine was slid into place and ready for business. At the same time another crew had got the big steam boiler ready. There was a tank of fuel oil at hand, and the feed-pipe was hitched up, and she was ready to make steam. And meantime the next truck was backed into place, and the skids put under the “draw-works”; when Bunny came back the next morning he found the big “drum” bolted into place, and the running tackle up in the derrick, and they were unloading the “drill-stem.” They would fit a steel chain about three of the heavy pipes at once, and a pulley with a steel hook would come down and seize the chain; the engine would start thumping, and the chain and the steel cable would draw tight, and the pipe would slide off the truck. These pipes were twenty feet long, and weighed nineteen pounds to the foot, and when you had your well a mile deep, you could figure it for yourself, there was fifty tons of steel, and your derrick had to carry that weight, and your steel cables had to lift it, and your drum and engine had to stand the strain. People kicked at the price of gasoline, but they never thought about the price of drill-stem and casings! All these things Bunny had heard a hundred times, but Dad never tired of telling them. He was never entirely content unless the boy was by his side, learning the business. You mustn’t fool yourself with the idea that you could hire experts to attend to things; for how could you know that a man was an expert, unless you knew as much as he did? Some day your foreman might drop dead, or some other fellow would buy him away from you, and then where would you be? Be your own expert, said Dad! The machinery which did the turning was called a “rotary table”; it was connected with the engine by a steel chain, exactly like the sprocket-chain of a bicycle, except that the links were as big as your fist. The rotary table had a hole through the centre, where the drill-stem went through; there was a corresponding hole in the derrick-floor—and soon there would be one in the ground! The hole in the rotary-table was square, and the top drill-stem, known as your “Kelly joint,” was square, and fitted this hole; you lowered it through—but first you screwed in your “collar” and “bit,” the tool which did the actual cutting. They were starting with a “disc-bit”—it had two steel things like dinner-plates, set opposite each other, and as they went round and round, the weight of the pipe caused them to chew their way into the earth. You started with an eighteen-inch “bit,” and as it flopped round, it cut you a hole two feet across.
