Страница 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.
Страница 156 - Soft roll your incense, herbs, and fruits, and flowers, In mingled clouds to Him, whose sun exalts, • Whose breath perfumes you, -and whose pencil paints.
Страница ii - District, has deposited in this office the title of a book, the right whereof he claims as proprietor, in the words following, to wit : " THE CHILD'S BOTANY," In conformity to the act of the Congress of the United States, entitled, " An act for the encouragement of learning by securing the copies of maps, charts, and books to the authors and proprietors of such copies, during the times therein mentioned...
Страница 228 - A man of a polite imagination is let into a great many pleasures that the vulgar are not capable of receiving. He can converse with a picture and find an agreeable companion in a statue. He meets with a secret refreshment in a description, and often feels a greater satisfaction in the prospect of fields and meadows, than another does in the possession.
Страница 230 - THESE, as they change, ALMIGHTY FATHER, these Are but the varied God. The rolling year Is full of THEE. Forth in the pleasing Spring THY beauty walks, THY tenderness and love. Wide flush the fields ; the softening air is balm ; Echo the mountains round ; the forest smiles ; And every sense, and every heart is joy. Then comes THY glory in the Summer months, With light and heat refulgent. Then THY sun...

As when the eagle from the ark First sported in thy beam. For, faithful to its sacred page, Heaven still rebuilds thy span • Nor lets the type grow pale with age That first spoke peace to man.
Страница 88 - ... gaze, And steers, undoubting, to the friendly coast ; And they who stray in perilous wastes, by night, Are glad when thou dost shine to guide their footsteps right. And, therefore, bards of old, Sages, and hermits of the solemn wood, Did in thy beams behold A beauteous type of that unchanging good, That bright eternal beacon, by whose ray The voyager of time should shape his heedful way.
Страница 20 - The world is full of poetry — the air Is living with its spirit ; and the waves Dance to the music of its melodies, And sparkle in its brightness. 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.
Страница 211 - As beasts excel cold rocks and brambles rude ; Men, who their duties know, But know their rights, and, knowing, dare maintain...
Страница 68 - Horrid with frost and turbulent with storm, Blows autumn, and his golden fruits, away : Then melts into the spring : soft spring, with breath Favonian, from warm chambers of the south, Recalls the first.
