The summer nights are short <br />Where northern days are long: <br />For hours and hours lark after lark <br />Trills out his song. <br />The summer days are short <br />Where southern nights are long: <br />Yet short the night when nightingales <br />Trill out their song.<br /><br />Christina Georgina Rossetti<br /><br />http://www.poemhunter.com/poem/the-summer-nights-are-short/
