The use of "occasional poems" is to give leave to originality. Every one delights in the felicity frequently shown in our drawing-rooms. In a game-party or picnic poem each writer is released from the solemn rhythmic traditions which alarm and suffocate his fancy, and the result is that one of the partners offers a poem in a new style that hints at a new literature. Yet the writer holds it cheap, and could do the like all day. On the stage, the farce is commonly far better given than the tragedy, as the stock actors understand the farce, and do not understand the tragedy. The writer in the parlor has more presence of mind, more wit and fancy, more play of thought, on the incidents that occur at table, or about the house, than in the politics of Germany or Rome. Many of the fine poems of Herrick, Jonson, and their contemporaries had this casual origin. I know there is entertainment and room for talent in the artist's selection of ancient or remote subjects; as when the poet goes to India, or to Rome, or Persia, for his fable. But I believe nobody knows better than he, that herein he consults his ease, rather than his strength or his desire. He is very well convinced that the great moments of life are those in which his own house, his own body, the tritest and nearest ways and words and things, have been illuminated into prophets and teachers. What else is it to be a poet? What are his garland and singing robes? What but a sensibility so keen that the scent of an elder-blow, or the timber-yard and corporation-works of a nest of pismires is event enough for him,--all emblems and personal appeals to him. His wreath and robe is to do what he enjoys; emancipation from other men's questions, and glad study of his own; escape from the gossip and routine of society, and the allowed right and practice of making better. He does not give his hand, but in sign of giving his heart; he is not affable with all, but silent, uncommitted, or in love, as his heart leads him. There is no subject that does not belong to him,--politics, economy, manufactures, and stock-brokerage, as much as sunsets and souls; only, these things, placed in their true order, are poetry; displaced, or put in kitchen order, they are unpoetic. Malthus is the right organ of the English proprietors; but we shall never understand political economy, until Burns or Béranger or some poet shall teach it in songs, and he will not teach Malthusianism. Poetry is the _gai science_. The trait and test of the poet is that he builds, adds, and affirms. The critic destroys: the poet says nothing but what helps somebody; let others be distracted with cares, he is exempt. All their pleasures are tinged with pain. All his pains are edged with pleasure. The gladness he imparts he shares. As one of the old Minnesingers sung,-- "Oft have I heard, and now believe it true, Whom man delights in, God delights in too."
