Yes, it took money to drill an oil well out here in California; it wasn’t like the little short holes in the East, where you pounded your way down by lifting up your string of tools and letting them drop again. No siree, here you had to be prepared to go six or seven thousand feet, which meant from three hundred to three hundred and fifty joints of pipe; also casing, for you could not leave this hole very long without protection. There were strata of soft sand, with water running through, and when you got past these you would have to let down a cylinder of steel or wrought iron, like a great long stove pipe; joint after joint you would slide down, carefully rivetting them together, making a water-proof job; and when you had this casing all set in cement, you would start drilling with a smaller bit, say fourteen inches, leaving the upper casing resting firmly on a sort of shelf. So you would go, smaller and smaller, until, when you got to the oil-sands, your hole would have shrunk to five or six inches. If you were a careful man, like Dad, you would run each string of casing all the way up to the derrick-floor, so that in the upper part of the hole you would have four sets of casing, one inside the other. All day and all night the engine labored, and the great chain pulled, and the rotary-table went round and round, and the bit ate into the rock. You had to have two shifts of men, twelve hours each, and because living quarters were scarce in this sudden rush, they kept the same bed warm all the time. A crew had to be on the job every moment, to listen and to watch. The engine must have plenty of water and gas and oil; the pump must be working, and the mud-river circulating, and the mixing-machine splashing, and the drill making depth at the proper rate. There were innumerable things that might go wrong, and some of them cost money, and some of them cost more money. Dad was liable to be waked up at any hour of the night, and he would give orders over the telephone, or perhaps he would slip into his clothes and drive out to the field. And next morning, at breakfast, he would tell Bunny about it; that fellow Dan Rossiger, the night-foreman, he sure was one balky mule; he jist wouldn’t make any time, and when you kicked, he said, “All right, if you want a ‘twist-off’.” And Dad had said, “‘Twist-off’ or no ‘twist-off,’ I want you to make time.” And so, sure enough, there was a “twist-off,” right away! Dad vowed that Dan had done it on purpose; there were fellows mean enough for that—and, of course, all they had to do was to speed up the engine.
