Silver bark of beech, and sallow
Bark of yellow birch and yellow
Twig of willow.
Stripe of green in moosewood maple,
Colour seen in leaf of apple,
Bark of popple.
Wood of popple pale as moonbeam,
Wood of oak for yoke and barn-beam,
Wood of hornbeam.
Silver bark of beech, and hollow
Stem of elder, tall and yellow
Twig of willow.
Edna St. Vincent Millay
