Quotes about Navies

For I dipp'd into the future, far as human eye could see,Saw the Vision of the world, and all the wonder that would be;Saw the heavens fill with commerce, argosies of magic sails,Pilots of the purple twilight, dropping down with costly bales;Heard the heavens fill with shouting, and there rain'd a ghastly dewFrom the nations' airy navies grappling in the central blue.
