They arrived at Paradise, and the instructor was duly installed in the fine new Spanish “ranch-house” which Dad had erected on the tract for the use of himself and his guests. It was built around the four sides of a court, with a fountain splashing in the center, and date-palms and banana plants and big shoots from the bougainvillea vine starting to climb the stucco walls. There was a Japanese who served the double function of butler and cook, and a boy who combined gardening with dish-washing, while Ruth had been promoted to be housekeeper and general boss. There were six guest-rooms, and when the executives and directors and geologists and engineers of Ross Consolidated came up to the tract, they were always Dad’s guests, and it was one big happy family. They would settle around a green baize table in the living-room right after supper and start playing poker; they would pull off their coats and unhitch their suspenders, and ring for the Jap to bring more cigars and whiskey and soda, and they would fill the room with blue smoke and never move from their seats until the small hours of the morning. It was an amusing illustration of the double standard of morals, that Dad was glad his son preferred to stay in his own room and read, and not hear the stories which the oil men would tell when they broke loose. But there was no gambling this time—this was to be a high-brow week-end, in honor of “the professor,” as Dad persisted in referring to his guest. The elder Ross was naively proud to have a “professor” visiting him, and to show him the well that was spudding in, and the one that was bailing, and the score that were drilling. They inspected the new refinery, something really special, that had been exploited in the newspapers as the latest miracle in petroleum engineering; incidentally it was a work of art, buildings of concrete and shining, newly-painted metal, set in a regular pleasure park. Oil wells are black and greasy, incurably so, but a refinery is different; the stuff comes in underground pipes, and most of it is taken away in the same fashion, so a refinery can be laid out according to the taste of a young idealist, with neat fences of steel mesh covered with rose vines, and plots of grass with gravelled roads winding between. The Ross refinery was as big as a good-sized village, only most of its houses were tanks; big tanks and little tanks, high tanks and squat tanks, round tanks, oblong tanks and square tanks, black tanks, red tanks, and tanks with an infinite variety of colors inside where they did not show.
