It was now easy to yoke the bulls, and to harness them to the plough, which had lain rusting on the ground for a great many years gone by; so long was it before anybody could be found capable of ploughing that piece of land. Jason, I suppose, had been taught how to draw a furrow by the good old Chiron, who, perhaps, used to allow himself to be harnessed to the plough. At any rate, our hero succeeded perfectly well in breaking up the greensward; and, by the time that the moon was a quarter of her journey up the sky, the ploughed field lay before him, a large tract of black earth, ready to be sown with the dragon's teeth. So Jason scattered them broadcast, and harrowed them into the soil with a brush-harrow, and took his stand on the edge of the field, anxious to see what would happen next.
