- 1898, Winston Churchill, chapter 8, The Celebrity:
- Now we plunged into a deep shade with the boughs lacing each other overhead, and crossed dainty, rustic bridges over the cold trout-streams, the boards giving back the clatter of our horses' feet: or anon we shot into a clearing, with a colored glimpse of the lake and its curving shore far below us.
