"..But in through the open window,
        Which I had forgot to close,
There had burst a gush of sunshine
        And a summer scent of rose.

For all the while I had burrowed
        There in my dingy tower,
Lo! the birds had sung and the leaves had danced
        From hour to sunny hour.

And such balm and warmth and beauty
        Came drifting in since then,
That window still stands open
        And shall never be shut again."
