Where... where...

But why it was there came a time
When we could take the road no more,
Through long we looked, and high would climb,
Or gaze from many a seaward shore
To find the path between sea and sky
To those old gardens of delight;
And how it goes now in that land,
If there the house and gardens stand,
Still filled with children clad in white-
We know not, You and I.
