found Mr. William Cullen Bryant again in the Laura Ingalls Wilder Pioneer Girl Book.....

footnote 109. p.324."The moon is at its full...asleep to-night." Wilder excerpted and slightly misquoted these lines from "The Tides" by American poet William Cullen Bryant

The moon is at her full, and, riding high,

Floods the calm fields with light.

The airs that hover in the summer sky

Are all asleep to-night. (Thirty Poems, p. 78)
