Robert William Service - The Comforter

As I sat by my baby's bed
That's open to the sky,
There fluttered round and round my head
A radiant butterfly.

And as I wept -- of hearts that ache
The saddest in the land --
It left a lily for my sake,
And lighted on my hand.

I watched it, oh, so quietly,
And though it rose and flew,
As if it fain would comfort me
It came and came anew.

Now, where my darling lies at rest,
I do not dare to sigh,
For look! there gleams upon my breast
A snow-white butterfly.

Robert William Service
