Clouds are mountains of the sky . . .

"Cumuli rising to the eastward . . . Mountains of the sky, solid-looking, finely sculptured, their richly varied topography wonderfully defined . . . One may fancy the clouds themselves are plants, springing up in the skyfields at the call of the sun, growing in beauty until they reach their prime, scattering rain and hail like berries and seeds, then wilting and dying."
