Compare and contrast the theme of the natural world in "On the Grasshoper and the Cricket" by Keats with "A Narrow Fellow in the Grass" by Dickinson.

Although both of these poems show respect and affection
for the natural world, I would say that Keats's poem is much more positive and
Dickinson's is much more negative in its view of nature.

In
Keats's poem, the tone is one of admiration and happiness.  We see that, no matter what,
there is always life in the natural world.  We are told that the poetry of the world,
the beauty of life, never ends.

In Dickinson's poem, by
contrast, there is a fear of nature.  The speaker can admire the snake, but that is not
the main point.  The main point is that the snake always inspires fear in
her.

So Dickinson's poem is much more negative -- its main
idea is the fear that nature can inspire, not its beauty.
