How does Louise Bogan use imagery in Words for Departure?

Bogan makes wide use of simile to evoke imagery....

Birds scattered and settled over chimneypots. As among grotesque trees.

There was a moon, and light in a shop-front, And dusk falling like precipitous water.

Additionally, Bogan includes images from nature to illustrate the disruption in her natural world. She also includes an image of the lovers' parting, with hands clasped and foreheads touching, an image that reveals the depth of loss that shakes her being. The contrasting images Bogan includes help create tension in the poem and add to its complexity.
