And so Yeats provides in the concluding stanza his vision for the comic ending he desires to his daughter's coming-of-age story--comic in the classic sense, a story that will conclude in the rituals of the marriage:
And may her bridegroom bring
her to a house
Where all's accustomed, ceremonious.
The image of the house returns again, now not the fragile and threatened world that opens the poem, offering poor protection from "the storm" without; but now a place that embodies the very virtues Yeats values most: custom, and ceremony.
For arrogance and hatred are
the wares
Peddled in the thoroughfares.
How but in custom and in ceremony
Are innocence and beauty born?
And in the final couplet, Yeats returns to the image of the horn, now not as a treasure that is wasted, but as the very source of these nurturing and enriching values that he hopes will restore the world:
Ceremony's a name for the rich
horn,
And custom for the spreading
laurel tree.
