Most of the luxuries and many of the so-called comforts of life are not only not indispensable but positive hindrances to our progress. Our life is frittered away by detail. I say let your affairs be as two or three, not a hundred or a thousand. And keep your accounts on your thumb nail.
Henry David ThoreauThe most primitive places left with us are the swamps, where the spruce still grows shaggy with usnea.
Henry David ThoreauTo 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.
