Emily Dickinson (December 10, 1830 – May 15, 1886 / Amherst / Massachusetts)

I think that since, for the first time, it rhymes its wonderful. But I don't exactly understand what she means by 'whose coat of elemental brown'

I'm doing a project on Emily Dickinson for my 11th grade American Literature class, and i need to find a poem by Miss Emily Dickinson and then analyze it, i chose this poem, but i don't really understand it, so if anybody could please explain it to me and help me to better understand it, i would be extremely grateful.

No worries, no problems, no grief just existence. It's existence is very simple, staying there in its place, rain or shine. The author must be a bit frustrated with her task and focuses her gaze on a stone, sitting there seeming peaceful. You only get one shot at a life like this so it would be best to enjoy it, the smile after you have moved on, the relief after a hard test has been done. We were made to be something better than the stone, not just to sit around there and do nothing.
