Σελίδα 264 - 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.
Σελίδα 243 - What Constitutes a State? WHAT constitutes a State? Not high-raised battlement or labored mound, Thick wall or moated gate — Not cities proud with spires and turrets crowned — Not bays and broad-armed ports, Where, laughing at the storm, rich navies ride — Not starred and spangled courts, Where low-browed baseness wafts perfume to pride. No; men, high-minded men...
Σελίδα 264 - 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.
Σελίδα 76 - And yet, fair bow, no fabling dreams, But words of the Most High, Have told why first thy robe of beams Was woven in the sky.
Σελίδα 77 - O'er mountain, tower, and town, Or, mirrored in the ocean vast, A thousand fathoms down ! As fresh in yon horizon dark, As young thy beauties seem. 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.
Σελίδα 118 - ... 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.
Σελίδα 243 - As beasts excel cold rocks and brambles rude ; Men, who their duties know, But know their rights, and, knowing, dare maintain...
Σελίδα 230 - How many merchants and carriers, besides, must have been employed in transporting the materials from some of those workmen to others who often live in a very distant part of the country ? How much commerce and navigation in particular, how many ship-builders, sailors, sail-makers, rope-makers, must have been employed in order to bring together the different drugs made use of by the dyer, which often come from the remotest corners of the world...
Σελίδα 100 - 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.
Σελίδα 240 - A strong sense of the value and blessings of union induced the people at a very early period to institute a federal government to preserve and perpetuate it. They formed it almost as soon as they had a political existence; nay, at a time when their habitations were in flames, when many of...
