Provided with a case of pencils, and some sheets of paper, I used to take a seat apart from them, near the window, and busy myself in sketching fancy vignettes representing any scene that happened momentarily to shape itself in the ever-shifting kaleidoscope of imagination: a glimpse of sea between two rock; the rising moon, and a ship crossing its disc; a group of reeds and water-flags, and a naiad's head, crowned with lotus-flowers, rising out of them; an elf sitting in a hedge-sparrow's nest, under a wreath of hawthorn bloom.
