There is a garden where lilies

There is a garden where lilies
And roses are side by side;
And all day between them in silence
The silken butterflies glide.

I may not enter the garden,
Though I know the road thereto;
And morn by morn to the gateway
I see the children go.

They bring back light on their faces;
But the' cannot bring back to me
What the lilies say to the roses,
Or the songs of the butterflies be.
