The Island Pharisees by John Galsworthy

One day towards the end of August Shelton took Antonia on the river -- the river that, like soft music, soothes the land; the river of the reeds and poplars, the silver swan-sails, sun and moon, woods, and the white slumbrous clouds; where cuckoos, and the wind, the pigeons, and the weirs are always singing; and in the flash of naked bodies, the play of waterlily leaves, queer goblin stumps, and the twilight faces of the twisted tree-roots, Pan lives once more.

The reach which Shelton chose was innocent of launches, champagne bottles and loud laughter; it was uncivilised, and seldom troubled by these humanising influences. He paddled slowly, silent and absorbed, watching Antonia. An unaccustomed languor clung about her; her eyes had shadows, as though she had not slept; colour glowed softly in her cheeks, her frock seemed all alight with golden radiance. She made Shelton pull into the reeds, and plucked two rounded lilies sailing like ships against slow-moving water.
