"Sure," Dick concurred. "But the farmer has to have his front porch somewhere on his ten acres. And the front porch represents the house, the barn, the chicken yard and the various outbuildings. Very well. Let him get tradition out of his mind, and, instead of building these things in the center of his ten acres, let him build them on the three acres of fringe. And let him plant his fruit and shade trees and berry bushes on the fringe. When you come to consider it, the traditionary method of erecting the buildings in the center of a rectangular ten acres compels him to plow around the center in broken rectangles." Gulhuss nodded enthusiastically. "Sure. And there's always the roadway from the center out to the county road or right of way. That breaks the efficiency of his plowing. Break ten acres into the consequent smaller rectangles, and it's expensive cultivation." "Wish navigation was as automatic," was Captain Lester's contribution. "Or portrait painting," laughed Rita Wainwright with a significant glance at Mr. Deacon. "Or musical criticism," Lute remarked, with no glance at all, but with a pointedness of present company that brought from O'Hay: "Or just being a charming young woman." "What price for the outfit?" Jeremy Braxton asked. "Right now, we could manufacture and lay down, at a proper profit, for five hundred. If the thing came into general use, with up to date, large-scale factory methods, three hundred. But say five hundred. And write off fifteen per cent, for interest and constant, it would cost the farmer seventy dollars a year. What ten-acre farmer, on two-hundred-dollar land, who keeps books, can keep a horse for seventy dollars a year? And on top of that, it would save him, in labor, personal or hired, at the abjectest minimum, two hundred dollars a year." "But what guides it?" Rita asked. "The drum on the post. The drum is graduated for the complete radius--which took some tall figuring, I assure you--and the cable, winding around the drum and shortening, draws the tractor in toward the center." "There are lots of objections to its general introduction, even among small farmers," Gulhuss said. Dick nodded affirmation. "Sure," he replied. "I have over forty noted down and classified. And I've as many more for the machine itself. If the thing is a success, it will take a long time to perfect it and introduce it." Graham found himself divided between watching the circling tractor and casting glances at the picture Paula Forrest was on her mount. It was her first day on The Fawn, which was the Palomina mare Hennessy had trained for her. Graham smiled with secret approval of her femininity; for Paula, whether she had designed her habit for the mare, or had selected one most peculiarly appropriate, had achieved a triumph.
