"Into a gradual calm the breezes sink,
A blue rim borders all the lake's still brink;
There doth the twinkling aspen's foliage sleep,
And insects clothe, like dust, the glassy deep:
And now, on every side, the surface breaks
Into blue spots, and slowly lengthening streaks;
Here, plots of sparkling water tremble bright
With thousand thousand twinkling points of light;
There, waves that, hardly weltering, die away,
Tip their smooth ridges with a softer ray;
And now the whole wide lake in deep repose
Is hushed, and like a burnished mirror glows,
Save where, along the shady western marge,
Coasts, with industrious oar, the charcoal barge (An Evening Walk Addressed to a Young Lady, William Wordsworth, 1793).
