In the time that I have been acquainted with this region I have become increasingly aware of it as a testament of water, the origin and guide of its contours and gradients and of all the lives - the plants and small creatures, and the culture - that evolved here. That was always here to be seen, of course, and the recognition has forced itself, in one form or other, upon people in every part of the world who have been directly involved with the growing of living things. The gardener who ignores it is soon left with no garden.
