The courage that my mother had

Went with her, and is with her still:

Rock from New England quarried;

Now granite in a granite hill.

The golden brooch my mother wore

She left behind for me to wear;

I have no thing I treasure more:

Yet, it is something I could spare.

Oh, if instead she'd left to me

The thing she took into the grave! -

That courage like a rock, which she

Has no more need of, and I have.

—“The Courage That My Mother Had,”
Edna St. Vincent Milla
