Question

Will someone please help me with scanning this poem? We just have to bold the stressed syllables.

Silver bark of beech, and sallow
Bark of yellow birch and yellow
Twig of willow.

Stripe of green in moosewood maple,
Color 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
