A pretty burn ran across the peaty moorland, close by the forest, and in places it had carved deep channels through the underlying rock, creating a series of miniature cliffs around enticing pools. It was far too cold to consider entering the water: despite the sunshine, there were still thin sheets of white ice in the shadier spots near the edges of the stream. But Algy found that it was very pleasant to recline on a flat rock in the sun, and watch the thousands of diamonds sparkling on the surface of the water as it tumbled over the pebbles and rough stone on its way down the hillside towards the sea.
