Now and then a pair of eyes would burn at us out of the dark ahead. I knew that they were the eyes of a cow-a poor dear stoic old cow with a cud, standing on the highway shoulder, for there wasn't any stock law-but her eyes burned at us out of the dark as though her skull were full of blazing molten metal like blood and we could see inside the skull into that bloody hot brightness in that moment when the reflection was right before we picked up her shape, which is so perfectly formed to be pelted with clods, and knew what she was and knew that inside that unlovely knotty head there wasn't anything but a handful of coldly coagulated gray mess in which something slow happened as we went by. We were something slow happening inside the cold brain of a cow.
