The brain within its groove <br />Runs evenly and true; <br />But let a splinter swerve, <br />'T were easier for you <br />To put the water back <br />When floods have slit the hills, <br />And scooped a turnpike for themselves, <br />And blotted out the mills!<br /><br />Emily Dickinson<br /><br />http://www.poemhunter.com/poem/the-brain-within-it-s-groove/
