He is too young yet to know life's demands; br Being no natural philosopher, br He must from cause and custom draw that art br Which some of Nature have, the primal gift br Of all her treasury — the open thought br That climates in all circumstances, and breathes br A native ease in everything; fear-proof, br Even as a wild bird's weather-proof, being born br And bred light as the leaves he habits in; br Unlike his brother housed and finely reared br With magisterial care, whom every change br Affects like a distemper, as if he br Had lost his nature's ancient art, and grew br Like an exotic with a borrowed life.
