Contexts of American Poetry Before 1925 Practice Test

And what I assume you shall assume,
For every atom belonging to me as good belongs to you.

I loafe and invite my soul,
I lean and loafe at my ease, observing a spear of summer grass.

Houses and rooms are full of perfumes— the shelves are crowded with perfumes,
I breathe the fragrance myself, and know it and like it,
The distillation would intoxicate me also, but I shall not let it.
