My mind went back to that picture in the obstetrics book. A cow standing in the middle of a gleaming floor while a sleek veterinary surgeon in a spotless parturition overall inserted his arm to a polite distance. He was relaxed and smiling, the farmer and his helpers were smiling, even the cow was smiling. There was no dirt or blood or sweat anywhere.That man in the picture had just finished an excellent lunch and had moved next door to do a bit of calving just for the sheer pleasure of it, as a kind of dessert. He hadn't crawled shivering from his bed at two o'clock in the morning and bumped over twelve miles of frozen snow, staring sleepily ahead till the lonely farm showed in the headlights. He hadn't climbed half a mile of white fell-side to the doorless barn where his patient lay.
