What is the rhyme scheme in "a slumber did my spirit seal" by william wordsworth?

a slumber did my spirit seal;
i had no human fears:
she seemed a thing that could not feel
the touch of earthly years.

no motion has she now, no force;
she neither hears nor sees;
rolled round in earth's diurnal course,
with rocks, and stones, and trees.
