Answer:
The speaker is revealing his fear of the snake. Meeting this creature, this “narrow fellow,” either “attended or alone” causes “tighter breathing.” It causes the speaker to feel “zero at the bone,” or to be chilled to the bone. The final stanza describes an irrational fear.
Step-by-step explanation:
Why was the snake called a narrow fellow? By using the word “like”, the speaker effectively personifies the snake. She has already called him a “fellow” and suggested that he “occasionally rides” thereby giving him human qualities from the start. Now, he is a snake who prefers a certain type of home. This further personifies the snake.
