The fear of an eclipse of the moon and other celestial phenomena, owes something of its force and persistence to their unknown and inaccessible character. A child is easily annoyed at that great white thing, which seems like a human face to look down on him, and which never comes a step nearer to let him know what it really is. It may be conjectured too that a child's fear of clouds, when they take on uncanny forms, is supported by their inaccessibility; for he cannot get near them and touch them. It seems, however, according to some recent researches in America, that children's fear of celestial bodies, especially the moon and clouds, is connected with the thought that they may fall on them. The idea of these strange-looking objects above the head, having no visible support, and often taking on a threatening mien, may well give rise to fear in a child's breast akin to the superstitious fear of the savage. Self-moving objects, which are not manifestly living things, are apt to excite a feeling of alarm in children, as indeed to some extent in the more intelligent animals. Just as a dog will run away from a leaf whirled about by the wind, so children are apt to be terrified by the strange and quite irregular behaviour of a feather as it glides along the floor or lifts itself into the air. A girl of three, who happened to pull a feather out of her mother's eider-down quilt, was so alarmed at seeing it float in the air that she would not come near the bed for days afterwards. Shrewd nurses know of this weakness, and have been able effectually to keep a child in a room by putting a feather in the keyhole. The fear here seems to be of something which simulates life and yet is not recognisable as a familiar living form. It was, I suppose, the same uncanny suggestion of life which made a child of four afraid at the sight of a leaf floating on the water of the bath-tub. Fear of feathers is, I believe, known among the superstitions of adults. This simulation of life by what is perceived to be not alive probably takes part in other forms of childish dread. Toys which take on too impudently the appearance of life may excite fear, as, for example, a toy cow which "moved realistically when it reared its head," a combination which completely scared its possessor, a boy about the age of one and a half years. A child can itself _make_ its toy alive, and so does not want the toy-maker to do so. The fear of shadows, which appears among children as among superstitious adults, seems to arise partly from their blackness and eerie forms, partly from their uncanny movements and changes of form. Some of us can recall with R. L. Stevenson the childish horror of going up a staircase to bed when, ... all round the candle the crooked shadows come, And go marching along up the stair. One's own shadow is worst of all, doggedly pursuing, horribly close at every movement, undergoing all manner of ugly and weird transformations. CHAPTER VIII.
