Famous quotes containing the words trail and/or difficulty:
“And Change with hurried hand has swept these scenes:
The woods have fallen, across the meadow-lot
The hunter’s trail and trap-path is forgot,
And fire has drunk the swamps of evergreens;
Yet for a moment let my fancy plant
These autumn hills again: the wild dove’s haunt,
The wild deer’s walk: in golden umbrage shut,”
—Frederick Goddard Tuckerman (1821–1873)
“A man’s love, till it has been chastened and fastened by the feeling of duty which marriage brings with it, is instigated mainly by the difficulty of pursuit.”
—Anthony Trollope (1815–1882)
