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.

Hilda Doolittle
