RIDERS OF THE PURPLE SAGE
that the herd moved in a great curve, a huge half-moon, with the points of head and tail almost opposite, and a mile apart. But Lassiter relentlessly crowded the leaders, sheering them to the left, turning them little by little. And the dust-blinded wild followers plunged on madly in the tracks of their leaders. This ever-moving, ever-changing curve of steers rolled toward Jane, and when below her, scarce half a mile, it began to narrow and close into a circle.
