A big elm in a single season might make as many as six million leaves, wholly intricate, without budging an inch; I couldn’t make one. A tree stands there, accumulating deadwood, mute and rigid as an obelisk, but secretly it seethes; it splits, sucks, and stretches; it heaves up tons and hurls them out in a green, fringed fling. No person taps this free power; the dynamo in the tulip tree pumps out ever more tulip tree, and it runs on rain and air.
