Among the heathy hills and ragged woods <br />The roaring Fyers pours his mossy floods; <br />Till full he dashes on the rocky mounds, <br />Where, thro' a shapeless breach, his stream resounds. <br />As high in air the bursting torrents flow, <br />As deep recoiling surges foam below, <br />Prone down the rock the whitening sheet descends, <br />And viewless Echo's ear, astonished, rends. <br />Dim-seen, through rising mists and ceaseless show'rs, <br />The hoary cavern, wide surrounding, lours: <br />Still thro' the gap the struggling river toils, <br />And still, below, the horrid cauldron boils -<br /><br />Robert Burns<br /><br />http://www.poemhunter.com/poem/lines-on-the-fall-of-fyers-near-loch-ness/
