Lesson 7 of 12

Reading water: colour, flow and surface

40 min

Kneel by any stream and look properly. The water has a colour, even when it looks clear. Its surface has a pattern: smooth here, broken there, a V shape behind a hidden stone, a foam line along the edge of an eddy. On a lake, the wind writes on the surface, and the shore it blows towards collects everything that floats.
