No dip and dart of swallows wakes the black
Slumber of the canal:—a mirror dead
For lack of loveliness remembered
From ancient azures and green trees, for lack
Of some white beauty given and flung back,
Secret, to her that gave: no sun has bled
To wake an echo here of answering red;
The surface stirs to no leaf's wind-blown track.
Between unseeing walls the waters rest,
Lifeless and hushed, till suddenly a swan
Glides from some broader river blue as day,
And with the mirrored magic of his breast
Creates within that barren water-way
New life, new loveliness, and passes on.
