How impossible it is ever to learn anything by being told it! How necessary it is to pay the full price for any knowledge worth having! The anxious father, the tearful mother, may warn the little boy before he goes to school of the dangers that await him. He does not understand, he does not attend, he is looking at the pattern of the carpet, and wondering for the hundredth time whether the oddly-shaped blue thing which appears and reappears at intervals is a bird or a flower--yes, it is certainly meant for a bird perched on a bough! He wishes the talk were over, he looks at the little scar on his father's hand, and remembers that he has been told that he cut it in a cucumber-frame when he was a boy. And then, long afterwards perhaps, when he has made a mistake and is suffering for it, he sees that it was THAT of which they spoke, and wonders that they could not have explained it better. And this is so all along! We cannot recognise the dark tower, to which in the story Childe Roland came, by any description. We must go there ourselves; and not till we feel the teeth of the trap biting into us, do we see that it was exactly in such a place that we had been warned that it would be laid. There is an episode in that strange and beautiful book Phantastes, by George Macdonald, which comes often to my mind. The boy is wandering in the enchanted forest, and he is told to avoid the house where the Daughter of the Ogre lives. His morose young guide shows him where the paths divide, and he takes the one indicated to him with a sense of misgiving. A little while before he had been deceived by the Alder-maiden, and had given her his love in error. This has taken some of the old joy out of his heart, but he has made his escape from her, and thinks he has learned his lesson.
