Letter to William H. Channing
p213“Tieck who has embodied so many Runic secrets explained to me what I have often felt when he tells of the poor changeling child when turned from the door of her adopted home she sat down on a stone and felt such a pity for herself that she wept.”

Hudspeth identified: 'Fuller refers to Ludwig Tieck's "Blonde Eckbert," Fuller refers to two specific elements of the story: (1) the 'poor changeling child' who weeps on a stone when turned from her adopted home — this is Bertha in the tale; (2) 'the wonderful bird singing in the wild forest' — the magic bird that Bertha stole and that sings a distinctive song.
