AN ESSAY.

Fortnightly Review, vol. iii. p. 129.]

"The gentle Mother of all

Showed me the lore of colors and of sounds;
The innumerable tenements of beauty;
The miracle of generative force;

Far-reaching concords of Astronomy

Felt in the plants and in the punctual birds;
Mainly, the linked purpose of the whole;
And, chiefest prize, found I true liberty-
The home of homes plain-dealing Nature gave.
