Summer on the Lakes, in 1843
“We have a nursery tale, of which children never weary, of a little boy visiting a bear house and holding intercourse with them on terms as free as Muckwa did.”
Fuller, Margaret. Summer on the Lakes, in 1843. Boston: Little, Brown & Co., 1844.
Inferred Fuller alludes to 'Orson,' the twin brother in the medieval French romance Valentine and Orson (Valentijn et Ourson), who is raised by bears in the forest and becomes a wild man.
