There are many touching stories by which this might be illustrated. One of them comes from a large steel mill of a boy of fifteen whose business it was to throw a lever when a small tank became filled with molton metal. During the few moments when the tank was filling it was his foolish custom to catch the reflection of the metal upon a piece of looking-glass, and to throw the bit of light into the eyes of his fellow workmen. Although an exasperated foreman had twice dispossessed him of his mirror, with a third fragment he was one day flicking the gloom of the shop when the neglected tank overflowed, almost instantly burning off both his legs. Boys working in the stock yards, during their moments of wrestling and rough play, often slash each other painfully with the short knives which they use in their work, but in spite of this the play impulse is too irrepressible to be denied. If educators could go upon a voyage of discovery into that army of boys and girls who enter industry each year, what values might they not discover; what treasures might they not conserve and develop if they would direct the play instinct into the art impulse and utilize that power of variation which industry so sadly needs. No force will be sufficiently powerful and widespread to redeem industry from its mechanism and materialism save the freed power in every single individual. In order to do this, however, we must go back a little over the educational road to a training of the child's imagination, as well as to his careful equipment with a technique. A little child makes a very tottering house of cardboard and calls it a castle. The important feature there lies in the fact that he has expressed a castle, and it is not for his teacher to draw undue attention to the fact that the corners are not well put together, but rather to listen to and to direct the story which centers about this effort at creative expression. A little later, however, it is clearly the business of the teacher to call attention to the quality of the dovetailing in which the boy at the manual training bench is engaged, for there is no value in dovetailing a box unless it is accurately done. At one point the child's imagination is to be emphasized, and at another point his technique is important--and he will need both in the industrial life ahead of him.
