The Botanist's Vision

The sun that in Breadalbane's lake doth fall
Was melting to the sea down golden Tay,
When a cry came along the peopled way,
'Sebastopol is ours!' From that wild call
I turned, and leaning on a time-worn wall
Quaint with the touch of many an ancient day,
The mapped mould and mildewed marquetry
Knew with my focussed soul; which bent down all
Its sense, power, passion, to the sole regard
Of each green minim, as it were but born
To that one use. I strode home stern and hard;
In my hot hands I laid my throbbing head,
And all the living world and all the dead
Began a march which did not end at morn.
