Answer:
A figure of speech is a word or phrase that possesses a separate meaning from its literal definition. It can be a metaphor or simile, designed to make a comparison. It can be the repetition of alliteration or the exaggeration of hyperbole to provide a dramatic effect.
In this case, the figurative speech in "From the Dark Tower" is clearer as it uses metaphors to illustrate the racial segregation. For example:
"We shall not always plant while others reap
The golden increment of bursting fruit(...)"
These first two lines open up the poem with the idea of struggle.
"I, Too" isn't as figurative.
"Tomorrow,
I'll be at the table
When company comes."
