What are poetic devices, including metaphor and personification, used by Vachel Lindsay in the poem "Flower-Fed Buffaloes."

Some poetic devices Lindsay uses in "The Flower-Fed
Buffaloes" are personification, hyperbole, metaphor, and imagery. Lines 3 and 4 begin
the personification. Personification is the giving of human qualities or behavior to
nonhuman objects. In line 3, "locomotives sing" as though they were human. In line 4
"prairie flowers lie low" as though they were napping in the grass as humans might
do.

Hyperbole is the use of exaggeration or overstatement
to make something larger than it is and more impressive or emphatic. In the title and
line 1, Lindsay opens with a beautiful hyperbolic image of buffaloes feeding on flowers.
Of course they fed more on grasses than on flowers, but the overstatement makes the
imagery more emphatic and the buffaloes more
sympathetic.

Lines 5 and 6 offer the best example of
imagery. Lindsay writes about the "The tossing, blooming, perfumed grass / Is swept away
by wheat." Here he uses tactile imagery, visual imagery, and olfactory imagery. Imagery
is language that calls up metal images in relation to things that can be felt (like
tossing), seen (like blooming), smelled (like perfume), heard (like locomotives
singing), or tasted (like flowers fed upon).

There are
other examples of poetic devices. One example of metaphor is line 8 in which "spring" is
called "sweet," implicitly comparing spring to a sweet treat--or to sweet tasting
flowers: "In the spring that still is sweet." Repetition makes lines 4, 12, and 13
important to Lindsay's message of loss as he repeats "lie low" with the variation of
"lying low."
