More from Thoreau

This is June, the month of grass and leaves. The deciduous trees are investing the evergreens and revealing how dark they are. Already the aspens are trembling again, and a new summer is offered me. I feel a little fluttered in my thoughts, as if I might be too late. Each season is but an infinitesimal point. It no sooner comes than it is gone. It has no duration. It simply gives a tone and hue to my thought.
