Flow, flow the waves hated, Accursed, adored, The waves of mutation: No anchorage is. Sleep is not, death is not; Who seem to die live. House you were born in, Friends of your spring-time, Old man and young maid, Day’s toil and its guerdon, They are all vanishing, Fleeing to fables, Cannot be moored. See the stars through them, Through treacherous marbles. Know, the stars yonder, The stars everlasting, Are fugitive also, And emulate, vaulted, The lambent heat-lightning, And fire-fly’s flight. When thou dost return On the wave’s circulation, Beholding the shimmer, The wild dissipation, And, out of endeavor To change and to flow, The gas become solid, And phantoms and nothings Return to be things, And endless imbroglio Is law and the world,— Then first shalt thou know, That in the wild turmoil, Horsed on the Proteus, Thou ridest to power, And to endurance. ILLUSIONS. Some years ago, in company with an agreeable party, I spent a long summer day in exploring the Mammoth Cave in Kentucky. We traversed, through spacious galleries affording a solid masonry foundation for the town and county overhead, the six or eight black miles from the mouth of the cavern to the innermost recess which tourists visit,—a niche or grotto made of one seamless stalactite, and called, I believe, Serena’s Bower. I lost the light of one day. I saw high domes, and bottomless pits; heard the voice of unseen waterfalls; paddled three quarters of a mile in the deep Echo River, whose waters are peopled with the blind fish; crossed the streams "Lethe" and "Styx;" plied with music and guns the echoes in these alarming galleries; saw every form of stalagmite and stalactite in the sculptured and fretted chambers,—icicle, orange-flower, acanthus, grapes, and snowball. We shot Bengal lights into the vaults and groins of the sparry cathedrals, and examined all the masterpieces which the four combined engineers, water, limestone, gravitation, and time, could make in the dark.
