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 rocks ; the rising moon , and a ship crossing its disk ; 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 我拿了画笔和画纸，远离她们，在一个靠窗的地方坐下，忙乎着画一些幻想的人头象，表现瞬息万变万花筒似的想象世界中刹那间出现的景象。例如，两块岩石之间的一片大海，初升的月亮，横穿月亮的一条船，一丛芦苇和景象，一个仙女头戴荷花从中探出头来，一个小精灵坐在一圈山楂花下的篱雀窝里。
