"Written on me was a message,
'At Your Service' like a book of
paper matches. One by one we were
taken out and struck.
We come bearing supper,
our heads on fire."
Jiles uses the simile-turned-metaphor of a match to convey the anger and self-defeating nature of the gender roles enforced when she was a child. Matches are small, relatively insignificant items that are sold in packages, and one is indistinguishable from another. They're nothing except when they're in use, and from the very nature of the job they're put to--being burned down to nothing--they're only good for one flame. These connotations brutally pare down what Jiles saw as woman's status in society when she was growing up. It seemed to her that women were hardly more than servants and not allowed much individuality--they all had one function, one appearance, etc. Another facet of the match-comparison is that matches are passive. Someone strikes up a flame with it, but matches can't do anything of their own decision.
Jiles' anger is conveyed by the final two lines, "We come bearing supper, / our heads on fire." This continues the match-metaphor, but also implies anger directly resulting from the servitude involved in bringing in supper. If someone's angry, they might be called "hot-headed,"--Jiles' women's heads are figuratively on fire, they're so incensed at their position.
Something slightly ironic in the image is that the match's/women's usefulness starts at their heads. In the male-dominated society Jiles describes, women's heads--brains--wouldn't be very valued. That their heads are on fire in the end suggests that their anger at their position is borne out of the fact that they can think, reason and realize the limitations being placed on them, and this in turn suggests a basis for women's equality and the injustice of their situation in this poem.
