Famous quotes containing the words trail and/or difficulty:
“Perhaps of all our untamed quadrupeds, the fox has obtained the widest and most familiar reputation.... His recent tracks still give variety to a winter’s walk. I tread in the steps of the fox that has gone before me by some hours, or which perhaps I have started, with such a tip-toe of expectation as if I were on the trail of the Spirit itself which resides in the wood, and expected soon to catch it in its lair.”
—Henry David Thoreau (1817–1862)
“Men were only made into “men” with great difficulty even in primitive society: the male is not naturally “a man” any more than the woman. He has to be propped up into that position with some ingenuity, and is always likely to collapse.”
—Wyndham Lewis (1882–1957)
