A change in the colour of the light usually called me in the morning. By a certain hour, the long, vertical chinks in our western gable, where the boards had shrunk and separated, flashed suddenly into my eyes as stripes of dazzling blue, at once so dark and splendid that I used to marvel how the qualities could be combined. At an earlier hour, the heavens in that quarter were still quietly coloured, but the shoulder of the mountain which shuts in the canyon already glowed with sunlight in a wonderful compound of gold and rose and green; and this too would kindle, although more mildly and with rainbow tints, the fissures of our crazy gable. If I were sleeping heavily, it was the bold blue that struck me awake; if more lightly, then I would come to myself in that earlier and fairer light.
