And this, of course, is what good poetry does. It seizes the moment, the situation, the thought; drags it palpitating from life and flings it, quivering with its own rhythmic movement, into expression. The thing cannot be done in mere prose, for there is more than explanation to the process. The words themselves, in their color and suggestiveness, the rhythms that carry them, contribute to the sense, even as overtones help to make the music. All this may sound a little exalted to the comfortable general reader, who does not often deal in such intense commodities as death and love. And yet I have mentioned nothing that does not at one time or another, and frequently rather than the opposite, come into his life, and need, not constant, certainly, but at least occasional, interpretation. Death and love, and also friendship, jealousy, courage, self-sacrifice, hate--these cannot be avoided. We must experience them. So do the animals, who gain from their experiences blind, instinctive repulsions or unreasoning likes and distrusts. There are many ways of escaping from such a bovine acquiescence, content to have felt, not desirous to grasp and know and relate. Poetry, which clears and intensifies like a glass held upon a distant snowpeak, is one of the best. But there is another service that poetry, among all writing, best renders to the general reader, _when he needs it_; a service less obvious, but sometimes, I think, more important. Poetry insures an extension of youth. Men and women vary in their emotional susceptibility. Some go through life always clouded, always dull, like a piece of glass cut in semblance of a gem, that refracts no colors and is empty of light. Others are vivid, impressionable, reacting to every experience. Some of us are most aroused by contact with one another. Interest awakens at the sound of a voice; we are most alive when most with our kind. Others, like Thoreau, respond best in solitude. The very thrush singing dimly in the hemlocks at twilight moves them more powerfully than a cheer. A deep meadow awave with headed grass, a solemn hill shouldering the sky, a clear blue air washing over the pasture slopes and down among the tree-tops of the valley, thrills them more than all the men in all the streets of the world. It makes no difference. To every one, dull and vivid, social and solitary, age brings its changes. We may understand better, but the vividness is less, the emotions are tamer. They do not fully respond, as the bell in the deserted house only half tinkles to our pulling. Si jeunesse savait, Si vielliesse pouvait. But to be able comes before to know. We must react to experiences before it is worth while to comprehend them. And after one is well enmeshed in the routine of plodding life, after the freshness of the emotions (and this is a definition of youth) is gone, it is difficult to react. I can travel now, if I wish, to the coral islands or the Spanish Main, but it is too late.
