The only light along the road for a great part of the way is that afforded by the motor's own lamps. Wonderful effects on the eye are often produced between lamplight and darkness, and commonplace objects often assume uncanny shapes and sizes. A number of heaps of stones intended for road-mending purposes had lain alongside a certain road for weeks. One night a motor van driver was startled by what appeared to be one of these heaps rising suddenly and approaching the coach. His heart went into his mouth, and he applied his brake, ready for a struggle with animated stones. And then to his relief— he was not anxious for miracles— an old white cow looked into his face; she had strayed on to the road; he had mistaken her for stones.
