What similarities can you find between a book and a frigate, a courser, and a chariot?

I believe this question is based on the poem by Emily Dickinson;

There is no frigate like a book

To take us lands away,

Nor any coursers like a page

Of prancing poetry.

This traverse may the poorest take

Without oppress of toll;

How frugal is the chariot

That bears a human soul!

From this poem, the similarity i can find between a book and a frigate, a courser, and a chariot is their ability to take an individual to a different place  physically or mentally. For effect, the book can take an individual to another place mentally, while the frigate, courser and chariot will take an individual to another place physically.

The ship, the horse, and the chariot are all rather romantic means of transportation. Like books, they provide ways of getting away from the ordinary world and of seeing faraway places.
