Ralph Waldo Emerson's "Fable" is just that -- a little story with animal characters and a moral. It's a moral that's acceptable even to young children: It's okay to be you and not someone else who's larger and more imposing! Emerson's choices give the poem a bit of a playful tone. He has paired together some unusual images in rhyme, and also suggested a rather squirrel-centric purpose for a mountain (as a squirrel track). this could be a fun poem for a bit of beginning rhetorical analysis.
