The tide comes in, a surge from the great sea, <br />And every little muddy creek and inlet <br />Now sweltering in the heat, will soon be filled <br />With the salt sweetness; even as sleep comes <br />After a term of toil to the tired brain, <br />A-surge from out the infinite, and fills <br />All of life's inlets with a dewy ease.<br /><br />Robert Crawford<br /><br />http://www.poemhunter.com/poem/sleep-compared-to-the-sea/
