When Hope but made Tranquillity be felt-- <br /> A Flight of Hopes for ever on the wing <br /> But made Tranquillity a conscious Thing-- <br /> And wheeling round and round in sportive coil <br /> Fann'd the calm air upon the brow of Toil--<br /><br />Samuel Taylor Coleridge<br /><br />http://www.poemhunter.com/poem/when-hope-but-made-tranquillity-be-felt-fragment/
