It was after twelve o'clock when Giles arrived and began unpacking his hammers. The sun had come out, and he was hot, tired and uncomfortable. But he soon forgot his discomfort when he examined the many interesting rocks. It was half-past three before he had finished. He packed his hammers and notebook away in his bag again and started on the journey back to Fablan Fawr. By this time the sky was cloudy again. As he walked along, light rain began to fall. Then, as he climbed higher, a thick, damp mist came down and covered everything. Soon the mist grew thicker and he could see only a few feet in front of him.
