What metaphors are used in The Verge by Susan Glaspell?

Numerous images, metaphors, and symbols of death and rebirth occur throughout The Verge. First and foremost are the symbolic elements lent by the plants. Through her plants, Claire brings forth life. She has the power to create this life, but she also has the power to destroy it, as she does at the end of act 1 with the Edge Vine. Claire also intimates throughout the play that she is not afraid of death and would perhaps find it a welcome respite from her horrible existence, "Why should we mind lying under the earth?" Claire believes that if people are "planted" in the earth, they might sprout forth anew into a better world. When she kills Tom at the end of the play, it is not out of malice, but love. She calls it her "gift" to him because in Claire's idiosyncratic mind, death is the best possibility for life.
