the coast of Norway

A breakfast-room adjoined the drawing-room, I slipped in there. It contained a bookcase: I soon possessed myself of a volume, taking care that it should be one stored with pictures. I mounted into the window-seat: gathering up my feet, I sat cross-legged, like a Turk; and, having drawn the red moreen curtain nearly close, I was shrined in double retirement.
Folds of scarlet drapery shut in my view to the right hand; to the left were the clear panes of glass, protecting, but not separating me from the drear November day. At intervals, while turning over the leaves of my book, I studied the aspect of that winter afternoon. Afar, it offered a pale blank of mist and cloud; near a scene of wet lawn and storm-beat shrub, with ceaseless rain sweeping away wildly before a long and lamentable blast.
I returned to my book—Bewick’s History of British Birds: the letterpress thereof I cared little for, generally speaking; and yet there were certain introductory pages that, child as I was, I could not pass quite as a blank. They were those which treat of the haunts of sea-fowl; of “the solitary rocks and promontories” by them only inhabited; of the coast of Norway, studded with isles from its southern extremity, the Lindeness, or Naze, to the North Cape—

“Where the Northern Ocean, in vast whirls,
Boils round the naked, melancholy isles
Of farthest Thule; and the Atlantic surge
Pours in among the stormy Hebrides.
