“To me be Nature’s volume broad display’d,
And to peruse its all-instructing page;
Or, haply catching inspiration thence
Some easy passage raptur’d to translate,
My sole delight.”

CHAPTER I

_ADAPTATION_

“My heart is awed within me, when I think
Of the great miracle that still goes on
In silence round me—the perpetual work
Of Thy creation, finished, yet renewed
For ever. Written on Thy works, I read
The lesson of Thine own eternity.”

+Bryant.+
