If I think of this poem as being a riddle, the answer to the riddle may be the word "pregnancy". I also have three
suggestions for the "nine syllables". First, the word "pregnancy" has nine syllables; second, there are nine lines in this poem, and third, in most situations a mother
is pregnant for nine months and then bear the baby. Maybe
it's the first time that the speaker had a baby in her body.She did not know exactly what to do. She wanted the readers to guess the riddle, and she was also looking for the best answer of what a pregnant woman should do.
She compared herself as "an elephant"," a ponderous house"
and " amelon strolling on two tendrils", becouse she was pregnant, and her body was heavy and large. It maight not very convenient for her to walk or do things at that time.
But there is a line that I do not understand: A red fruit, ivory, fine timbers. What does this line try to explain?
" Money's new-minted in this fat purse." I have two ideas about this line. First, she means that she is the fat purse and the new life in her body is the new-minted money.
Second, they may need to spend a lot of money to raise the baby in the future. And maybe they were not rich; she wished that they would have more money for the unborn baby.
When she had a baby, she should be responsible for the child, the family and the role she played as a mother. It is a kind of duty.So she said " Boarded the train there's no getting off".
Most women will be very happy when they have the babies. But I did not think the speaker is happy. The poem is not full of merriment and expection,but resignation. The speaker seemed a little upset, maybe it was becouse of her unsuccessful marriage.
