“silver”
by walter de la mare

slowly, silently, now the moon
walks the night in her silver shoon;
this way, and that, she peers, and sees
silver fruit upon silver trees;
one by one the casements catch
her beams beneath the silvery thatch;
couched in his kennel, like a log,
with paws of silver sleeps the dog;
from their shadowy cote the white breasts peep
of doves in a silver-feathered sleep;
a harvest mouse goes scampering by,
with silver claws and a silver eye;
and moveless fish in the water gleam,
by silver reeds in a silver stream.

which line from the poem best illustrates alliteration?

“from their shadowy cote the white breasts peep”
“walks the night in her silver shoon; ”
“a harvest mouse goes scampering by,"
“by silver reeds in a silver stream,”
