Nature is the armory of genius. Cities serve it poorly; books and colleges at second-hand; the eye craves the spectacle of the horizon, of mountain, ocean, river and plain, the clouds and stars: actual contact with the elements, sympathy with the seasons as these rise and fall.

Believe, youth, despite all temptations, the oracle of deity in your own bosom. ’T is the breath of God’s revelations,—the respiration of the Holy Ghost in your breast. Be faithful, not infidel, to its intuitions,—quench never its spirit,—dwell ever in its omniscience. So shall your soul be filled with light, and God be an indwelling fact,—a presence in the depths of your being.
