Page 228 - TO him who in the love of nature holds Communion with her visible forms, she speaks A various language; for his gayer hours She has a voice of gladness, and a smile And eloquence of beauty, and she glides Into his darker musings, with a mild And healing sympathy, that steals away Their sharpness, ere he is aware.

Earth is veiled, And mantled with its beauty; and the walls That close the universe with crystal in, Are eloquent with voices, that proclaim The unseen glories of immensity, In harmonies, too perfect, and too high, For aught but beings of celestial mould, And speak to man in one eternal hymn, Unfading beauty, and unyielding power.
