The whitethroat and his mate have jerked away, the willow bird slipped upstream, the cock-wren with cocked tail is stuttering an alarm. Down by the water’s edge a reddish animal nibbles a shoot held in its paws. Perceiving that it has no hostile bearing, the wren is silent. At the slightest movement the vole will dive with a musical and hollow plop into the water and swim to concealment. Quietly it finishes the sappy stalk, then creeps under a thick stem of cow-parsley, the florets of which are budding. Finches pass over, calling to each other, and a silver chirruping announces a wagtail. He alights on a smooth gray boulder, slender in outline and poised on fragile legs, flaunting a breast of daffodil. The hen-bird follows, and they perch together. Their long tails move as though to maintain an earthly balance, so faery-frail are they. She leaves him, flitting in wavy flight to another boulder. He follows, but she is restless. Downstream they pass, stopping for a moment on a jutting fragment of rock in the stone hedge, peering into a cavity. Throughout the summer the gray wagtails will haunt the brook, for within the cave foundations of their nest are already laid, fibres sought inside the pollard willows. Those galleons the clouds have sailed into the north-eastern main, and no canvas or furled rigging are visible. For weeks no treasure of rain has been brought for the earth to spend with lavish abandon on verdant raiment, no largesse of shower has been thrown to the humble chickweed or vagrant sorrel. But on the surface of the land green things are stained with sap and charged with alchemising sunbeams. The secret of the philosopher’s stone, anciently sought to change baser metals to gold, has remained undiscovered through the ages, nor has the countryman ever found the crock of spade guineas at the rainbow’s end. These would bring luck; even now we strive to find their counterpart. In the cities, perhaps: youth storing the gold that one day will mean happiness: towards the evening of life, maybe, with sight dulled to a flower and the song of the swallow never heard. Sunlight is all to the flowers. It distils for them their scents and sweet nectars, it fashions their petals and ambrosial pollen. The sun loads the galleons of the airy fullness with the rain drawn from the ocean, unlading its cargoes upon the million wharves of the earth.
