What is the summary of the poem the flower fed buffaloes by Vachel Lindsay?

The flower fed buffaloes poem is about the native Indian tribes in America, and how they were taken over by the industrialization of America.

"Perfumed grass" was replaced by wheat fields, and the "flower fed buffaloes" on which the native Americans had relied on in order to live, have been killed, thanks to industrialization.

The poem shows the helplessness of nature, and how industrialization has taken over severely.
