type of poetry

let me be sad
to clothe the fiery thought
the rain was over, and the brilliant air
i saw the archangels in my apple-tree last night
i never knew the earth had so much gold
the child who threw away leaf after leaf
i shake my hair in the wind of morning
a gleam of gold in gloom and gray
like him whose spirit in the blaze of noon
green afternoon serene and bright
i made a vow once, one only
i sometimes wonder if it's really true
wheel me down by the meadow
i have known the silence of the stars and of the sea
