Страница 90 - As when the moon, refulgent lamp of night! O'er heaven's clear azure spreads her sacred light, When not a breath disturbs the deep serene, And not a cloud o'ercasts the solemn scene; Around her throne the vivid planets roll, And stars unnumbered gild the glowing pole; O'er the dark trees a yellower verdure shed, And tip with silver every mountain's head.
Страница 108 - Like leaves on trees the race of man is found, Now green in youth, now withering on the ground; Another race the following spring supplies; They fall successive, and successive rise: So generations in their course decay; So flourish these, when those are pass'd away.
Страница 38 - That levying money for or to the use of the Crown, by pretence of prerogative, without grant of parliament, for longer time or in other manner than the same is or shall be granted, is illegal.
Страница 175 - What modes of sight betwixt each wide extreme, The mole's dim curtain, and the lynx's beam; Of smell, the headlong lioness between, And hound sagacious on the tainted green ; Of hearing, from the life that fills the flood, To that which warbles through the vernal wood. The spider's touch, how exquisitely fine ! Feels at each thread, and lives along the line...
Страница 164 - To view the structure of this little work, A bird's nest. Mark it well, within, without. No tool had he that wrought, no knife to cut, No nail to fix, no bodkin to insert, No glue to join; his little beak was all. And yet how neatly finish'd ! What nice hand, With ev'ry implement and means of art, And twenty years apprenticeship to boot, Could make me such another?
Страница 35 - In forest, brake or den, As beasts excel cold rocks and brambles rude ; Men who their duties know, But know their rights, and, knowing, dare maintain, Prevent the long-aimed blow, And crush the tyrant while they rend the chain ; These constitute a State; And sovereign law, that State's collected will, O'er thrones and globes elate Sits empress, crowning good, repressing ill.
Страница 39 - That excessive bail ought not to be required, nor excessive fines imposed ; nor cruel and unusual punishments inflicted. 11. That jurors ought to be duly impanelled and returned, and jurors which pass upon men in trials for high treason ought to be freeholders. 12. That all grants and promises of fines and forfeitures of particular persons before conviction, are illegal and void. 13. And that for redress of all grievances, and for the amending, strengthening, and preserving of the laws, Parliaments...
Страница 98 - 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. All, to re-flourish, fades ; As in a wheel, all sinks, to re-ascend. Emblems of man, who passes, not expires.
Страница 152 - See, thro' this air, this ocean, and this earth, All matter quick, and bursting into birth. Above, how high progressive life may go! Around, how wide! how deep extend below! Vast chain of being! which from God began, Natures...
Страница 241 - That which is now a horse, even with a thought The rack dislimns, and makes it indistinct, As water is in water.
