Page 400 - OH for a lodge in some vast wilderness, Some boundless contiguity of shade, Where rumour of oppression and deceit, Of unsuccessful or successful war, Might never reach me more.
Page 415 - To sit on rocks, to muse o'er flood and fell, To slowly trace the forest's shady scene, Where things that own not man's dominion dwell, And mortal foot hath ne'er, or rarely, been ; To climb the trackless mountain all unseen, With the wild flock that never needs a fold ; Alone o'er steeps and foaming falls to lean ; This is not solitude ; 'tis but to hold Converse with Nature's charms, and view her stores unroll'd.
