I
If suddenly a clod of earth should rise,
And walk about, and breathe, and speak, and love,
How one would tremble, and in what surprise
Gasp: 'Can you move?'

I see men walking, and I always feel:
'Earth! How have you done this? What can you be?'
I can't learn how to know men, or conceal
How strange they are to me.

II
A flower is looking through the ground,
Blinking at the April weather;
Now a child has seen the flower:
Now they go and play together.

Now is seems the flower will speak,
And will call the child its brother --
But, oh strange forgetfulness! --
They don't recognize each other.

Harold Monro
