"Gryll Grange"
Thomas Love Peacock Commentator: George Saintsbury
De Vries has shown that when a shoot of a vigorous plant, for instance a helianthus, is bent down under water, care being taken not to break it even in the slightest degree, a clean, sharp cut will give a surface which will retain the power of absorbing water for a long time; while a similar shoot cut in the open air, even if the end is instantly plunged under water, will wither much sooner than the first.
