Clouds are capable of calling out the strongest emotions of the soul--fear, depression, gloom, awe, reverence, joy, cheer and hope. Children take great delight in watching cloudscapes and in discovering objects in the constantly changing forms. Over one hundred different kinds of objects were recorded in the replies which were tabulated in this investigation. Richly illumined, iridescent and constantly changing cloudscapes afford a most fertile field for the exercise of imaginative creativeness. The masters who have charmed the race by their imaginative descriptions often have derived their most exquisite conceptions from the flying cloudscapes rather than from beautiful flowers, mountains, parks or buildings. No work of art can elevate the feelings to such lofty adoration of the marvels of nature as the colored glories of the sunset and sunrise (Biglow). The scenes of the Scandinavian gods and goddesses were staged in cloudland. The clouds have impressed themselves upon the cosmogony, mythology, religion, morals, beliefs and superstitions of primitive races as well as of modern children. The modern child’s emotional reactions are vestiges of ancestral attitudes towards clouds, while the modern painter and poet still find inspiration in cloudland. City smoke not only cheats us of our birthright, by depriving us of an important means for developing the powers of observation and imagination as well as of a source of aesthetic culture (because it covers the heavens with an opaque blanket); but it also displaces the cathedrals of nature with an uninteresting, nasty, black, opaque pall of soot which stimulates tendencies toward discontent and frequently arouses morbid emotions. Mankind has always taken a delight in color. Under primitive conditions man bedecks his body with colored habiliments for purely decorative rather than protective purposes. Deprived of the enjoyment of the natural terrestrial color effects by high buildings, man resorts to the artificial coloration of his buildings. But the smoke palls tend to subvert his every effort to satisfy the demands of his color sense. The abatement of smoke will do much to restore hue and chroma to their rightful places in the aesthetic development of manufacturing cities.
