"Most marvelous and enviable is that fecundity of fancy which can adorn whatever it touches, which can invest naked fact and dry reasoning with unlooked-for beauty, make flowers bloom even on the brow of the precipice, and, when nothing better can be had, can turn the very substance of rock itself into moss and lichens. This faculty is uncomparingly the most important for the vivid and attractive exhibition of truth to the minds of men."
