Book 2, Chapter 14 Quotes
On some upland farm, a plough had been left standing in the field. The sun was sinking just behind it.

There it was, heroic in size, a picture writing on the sun.
Even while we whispered about it, our vision disappeared; the ball dropped and dropped until the red tip went beneath the earth. The fields below us were dark, the sky was growing pale, and that forgotten plough had sunk back to its own littleness somewhere on the prairie.
