Страница 105 - MILTON ! thou shouldst be living at this hour : England hath need of thee : she is a fen Of stagnant waters : altar, sword, and pen, Fireside, the heroic wealth of hall and bower, Have forfeited their ancient English dower Of inward happiness. We are selfish men ; Oh ! raise us up, return to us again ; And give us manners, virtue, freedom, power.
Страница 22 - These are thy glorious works, Parent of good, Almighty, thine this universal frame, Thus wondrous fair ; thyself how wondrous then ! Unspeakable, who sitt'st above these heavens, To us invisible, or dimly seen In these thy lowest works; yet these declare Thy goodness beyond thought, and power divine.

Страница 58 - See Salem built, the labour of a God ! Bright as a sun the sacred city shines ; All kingdoms and all princes of the earth Flock to that light ; the glory of all lands Flows into her ; unbounded is her joy, . And endless her increase.
Страница 39 - The shades of night were falling fast, As through an Alpine village passed A youth, who bore, 'mid snow and ice, A banner with the strange device, Excelsior ! His brow was sad ; his eye beneath Flashed like a falchion from its sheath, And like a silver clarion rung The accents of that unknown tongue, Excelsior...
