Mother, the root of this little yellow flower

A poem by Edward Thomas (1878-1917):

Mother, the root of this little yellow flower
Among the stones has the taste of quinine.
Things are strange to-day on the cliff. The sun shines so bright,
And the grasshopper works at his sewing-machine
So hard. Here's one on my hand, mother, look;
I lie so still. There's one on your book.

But I have something to tell more strange. So leave
Your book to the grasshopper, mother dear, --
Like a green knight in a dazzling market-place, --
And listen now. Can you hear what I hear
Far out? Now and then the foam there curls
And stretches a white arm out like a girl's.

Fishes and gulls ring no bells. There cannot be
A chapel or church between here and Devon,
With fishes and gulls ringing its bell,--hark!--
Somewhere under the sea or up in heaven.
'It's the bell, my son, out in the bay
On the buoy. It does sound sweet to-day.'

Sweeter I never heard, mother, no, not in all Wales.
I should like to be lying under that foam,
Dead, but able to hear the sound of the bell,
And certain that you would often come
And rest, listening happily.
I should be happy if that could be.
