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)
“... the only way in which Mr. Brooke could be coerced into thinking of the right arguments at the right time was to be well plied with them till they took up all the room in his brain. But here there was the difficulty of finding room, so many things having been taken in beforehand. Mr. Brooke himself observed that his ideas stood rather in his way when he was speaking.”
—George Eliot [Mary Ann (or Marian)
