I think that Nature meant kindly when she made our brothers few. However, my voice is still for peace.

Thank God men cannot fly, and lay waste the sky as well as the earth.

The sugar maple is remarkable for its clean ankle. The groves of these trees looked like vast forest sheds, their branches stopping short at a uniform height, four or five feet from the ground, like eaves, as if they had been trimmed by art, so that you could look under and through the whole grove with its leafy canopy, as under a tent whose curtain is raised.

A truly good book attracts very little favor to itself. It is so true that it teaches me better than to read it. I must soon lay it down and commence living on its hint. When I read an indifferent book, it seems the best thing I can do, but the inspiring volume hardly leaves me leisure to finish its latter pages. It is slipping out of my fingers while I read. It creates no atmosphere in which it may be perused, but one in which its teachings may be practiced. It confers on me such wealth that I lay it down with regret. What I began by reading I must finish by acting.
