The dogs adapted to the snow like young bears, plunging into the drifts to emerge with white whiskers and bucking their way across the fields in huge, frothy leaps. And they learned to skate. The pool, that just days before I had been planning to clean and make ready for some early spring swimming, was a block of blue-green ice, and it seemed to fascinate them. On to the ice would go the two front paws, then a tentative third paw, and finally the remaining leg would join the rest of the dog. There would be a moment or two of contemplation at the curiosity of a life in which you can drink something one day and stand on it the next before the tail would start whirring with excitement and a form of progress could be made. I had always thought that dogs were engineered on the principle of four-wheel drive vehicles, with equal propulsion coming from each leg, but the power appears to be concentrated in the back. Thus the front half of the skating dog may have the intention of proceeding in a straight line, but the rear half is wildly out of control, fishtailing from side to side and sometimes threatening to overtake.

The novelty of being marooned in the middle of a picturesque sea was, during the day, a great pleasure. We walked for miles, we chopped wood, we ate enormous lunches and we stayed warm. But at night, even with fires and sweaters and yet more food, the chill came up from the stone floors and out of the stone walls, making the toes numb and the muscles tight with cold. We were often in bed by nine o'clock and often, in the early morning, our breath was visible in small clouds over the breakfast table. If the Menicucci theory was correct and we were living in a flatter world, all future winters were going to be like this. It was time to stop pretending we were in a sub-tropical climate and give in to the temptations of central heating.
