Silver dust
lifted from the earth,
higher than my arms reach,
you have mounted
O silver,
higher than my arms reach
you front us with great mass;
no flower ever opened
so staunch a white leaf,
no flower ever parted silver
from such rare silver,
O white pear,
your flower-tufts,
thick on the branch,
bring summer and ripe fruits
in their purple hearts
Which lines from the poem use imagery to create the mood?
