mythological impulse sometimes alternating with a more distinctly scientific impulse to grasp the mechanical process, as when wind is sometimes thought of, as caused by a big fan, and sometimes, _e.g._, when heard moaning in the night, endowed with life and feeling. I shall make no attempt to give a methodical account of children’s thoughts about nature. I suspect that a good deal more material will have to be collected before a complete description of these thoughts is possible. I shall content myself with giving a few samples of their ideas so far as my own studies have thrown light on them. With respect to the make or substance of things children are, I believe, disposed to regard all that they see as having the resistant quality of solid material substance. At first, that is to say after the child has had experience enough of seeing and touching things at the same time to know that the two commonly go together, he believes that all which he sees is tangible or substantial. Thus he will try to touch shadows, sunlight dancing on the wall, and picture forms. This tendency to “reify,” or make things of, his visual impressions shows itself in pretty forms, as when the little girl M., one year eleven months old, “gathered sunlight in her hands and put it on her face”. The same child about a month earlier expressed a wish to wash some black smoke. This was the same child that tried to make the wind behave by making her mother’s hair tidy; and her belief in the material reality of the wind was shown by her asking her mother to lift her up high so that she might see the wind. This last, it is to be noted, was an inference from touching and resisting to seeing.[45] Wind, it has been well remarked, keeps something of its substantiality for all of us long after shadows have become the type of unreality, proving that the experience of resisting something lies at the root of our sense of material substance. That older children believe in the wind as a living thing seems suggested by the readiness with which they get up a kind of play-tussle with it. That wind even in less fanciful moments is reified is suggested by the following story from the Worcester collection. A girl aged nine was looking out and seeing the wind driving the snow in the direction of a particular town, Milbury: whereupon she remarked, “I’d like to live down in Milbury”. Asked why, she replied, “There must be a lot of wind down there, it’s all blowing that way”. ----- Footnote 45: Compare R. L. Stevenson’s lines to the wind: “I felt you push, I heard you call, I could not see yourself at all”. _A Child’s Garden of Verse_, xxv. -----
