What is one purpose of the simile in this poem?

The last scud of day holds back for me,

It flings my likeness after the rest and true as any on the

shadow'd wilds,


It coaxes me to the vapor and the dusk.


I depart as air, I shake my white locks at the runaway sun,

I effuse my flesh in eddies, and drift it in lacy jags.

ATo link two unlike concepts: mountains and burial mounds

BTo make an animal seem like a peer to the speaker

CTo make a connection between the speaker and the reader

DTo compare the speaker to a force of nature
