Brown under the sunlight, shadeless and glaring, when a blustering north-easter is blowing down it, the Valley of Rocks is a bitter and inhospitable spot; I have been glad to go into the sheep-fold and crouch under the lee of the stone wall for a moment's respite from the wind and the stinging particles of sharp dust that it flung in my face as I battled up the road. Once, in such a wind, I climbed the Castle Rock, and squeezed myself between two great boulders looking seaward over the choppy water--it was a land wind, which does not send the waves rolling in great breakers, very splendid to see, but worries it and dirties it, leaving broken cross waves of muddy grey water--and I startled a pair of ravens who had built a nest on a sharp ledge of rock, just beyond where I sat, and had not heard me coming, because of the noise of the wind. They startled me also, as one of them flapped out, close to my face, and flew screaming away, as I pulled myself up into shelter, but the other stood on its jut of rock, almost within arm's length, and looked at me. I saw its ugly long head as it turned, its great beak and its neck of a bird of prey, and then it flew off; and though I sat very still for a long time, hoping they might return, they only flew round me and past me, showing me the great black sweep of their wings as they went. But as I sat there, on that wild crag and that wild morning, I noticed a tuft of dog-violets, growing out of a fissure in the grey rock, and shaken and pounded by the bitter wind. How wonderful is the tenacity of nature. A few grains of dust blown into a crack of barren rock, a few seeds wind-carried also, and then germination in the rain and sun, and when the spring comes, this little clump of flowers in its due season, part of the intricate and mighty forces of renewal throughout the fertile world.
