Describe the writing and artwork of Emmeline Grangerford. What does Huck think of her pictures and poems?

Basically, the late Emmeline Grangerford's art and poetry
was all completely morbid and sad.  As Huck says about her
poetry,

she
could write about anything you choose to give her to write about just so it was
sadful.

All of her pictures
are of dead or dying things.  She has one of a woman mourning at a grave.  She has one
of a woman mourning a dead bird.  The one she was working on when she died was a woman
about to commit suicide.  Her poetry was also about dead
people.

Huck says that he thinks all of her work is nice
but that he can't "take to it.  It is all too sad and it depresses him to see any of
it.
