To preserve wild animals implies generally the creation of a forest for them to dwell in or resort to. So it is with man. A hundred years ago they sold bark in our streets peeled from our own woods. In the very aspect of those primitive and rugged trees there was, methinks, a tanning principle which hardened and consolidated the fibres of men's thoughts. Ah! already I shudder for these comparatively degenerate days of my native village, when you cannot collect a load of bark of good thickness, and we no longer produce tar and turpentine.

We perceive that the schemers return again and again to common sense and labor. Such is the evidence of history.

I have found it to be the most serious objection to coarse labors long continued, that they compelled me to eat and drink coarsely also.

It is but too easy to establish another durable and harmonious routine. Immediately all parts of nature consent to it. Only make something to take the place of something, and men will behave as if it was the very thing they wanted.

A man may esteem himself happy when that which is his food is also his medicine.

I believe that it is in my power to elevate myself this very hour above the common level of my life.

We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.
