hours. "It cannot be," says Herbert, "that I am he on whom Thy tempests fell all night."
It is in the hours of sleep that the mind, by some divine paradox, has the extremest sense of light. Almost the most shining lines in English poetry—lines that cast sunrise shadows—are those of Blake, written confessedly from the side of night, the side of sorrow and dreams, and those dreams the dreams of little chimney-sweepers; all is as dark as he can make it with the "bags of soot"; but the boy's dream of the green plain and the river is too bright for day. So, indeed, is another brightness of Blake's, which is also, in his poem, a child's dream, and was certainly conceived by him in the hours of sleep, in which he woke to write the Songs of Innocence:—
O what land is the land of dreams?
What are its mountains, and what are its streams?
O father, I saw my mother there,
Among the lilies by waters fair.
Among the lambs clothéd in white,
She walk'd with her Thomas in sweet delight.
To none but the hours claimed and inspired by sleep, held awake by sufferance of sleep, belongs such a vision.
