Robert Louis Stevenson - Sonnet II

So shall this book wax like unto a well,
Fairy with mirrored flowers about the brim,
Or like some tarn that wailing curlews skim,
Glassing the sallow uplands or brown fell;
And so, as men go down into a dell
(Weary with noon) to find relief and shade,
When on the uneasy sick-bed we are laid,
We shall go down into thy book, and tell
The leaves, once blank, to build again for us
Old summer dead and ruined, and the time
Of later autumn with the corn in stook.
So shalt thou stint the meagre winter thus
Of his projected triumph, and the rime
Shall melt before the sunshine in thy book.

Robert Louis Stevenson
