Popular passages
Page 67 - And I have loved thee, Ocean ! and my joy Of youthful sports was on thy breast to be Borne, like thy bubbles, onward : from a boy I wantoned with thy breakers — they to me Were a delight : and if the freshening sea Made them a terror — 'twas a pleasing fear, For I was as it were a child of thee, And trusted to thy billows far and near, And laid my hand upon thy mane — as I do here.
Page 792 - The ice was here, the ice was there, The ice was all around: It cracked and growled, and roared and howled, Like noises in a swound!
Page 14 - Tis not too late to seek a newer world. Push off, and sitting well in order smite The sounding furrows; for my purpose holds To sail beyond the sunset, and the baths Of all the western stars, until I die. It may be that the gulfs will wash us down: It may be we shall touch the Happy Isles, And see the great Achilles, whom we knew. Tho' much is taken, much abides; and tho...
Page 115 - Roll on thou deep, and dark blue Ocean, roll ! Ten thousand fleets sweep over thee in vain, Man marks the earth with ruin— his control Stops with the shore ; upon the watery plain The wrecks are all thy deed...
Page 318 - With sloping masts, and dipping prow, As who pursued with yell and blow Still treads the shadow of his foe, And forward bends his head ; The ship drove fast, loud roared the blast, And southward aye we fled.
Page 254 - There are some days the happy ocean lies Like an unfingered harp, below the land. Afternoon gilds all the silent wires Into a burning music of the eyes. On mirroring paths between those fine-strung fires The shore, laden with roses, horses, spires, Wanders in water, imaged above ribbed sand.
Page 478 - Californian towns, but yesterday planted by the recentest race of men, and lave the faded but still gorgeous skirts of Asiatic lands, older than Abraham ; while all between float milky-ways of coral isles, and low-lying, endless, unknown Archipelagoes, and impenetrable Japans. Thus this mysterious, divine Pacific zones the world's whole bulk about; makes all coasts one bay to it; seems the tide-beating heart of earth.
Page 123 - The stability of a unit in each mode of operation should meet the following criteria (see also figure 1): . 1 For surface and self-elevating units the area under the righting moment curve to the second intercept or downflooding angle, whichever is less, should be not less than 40 per cent in excess of the area under the wind heeling moment curve to the same limiting angle.
Page 27 - Roughly speaking, 50 kA of current flows overhead in the ionosphere between each pair of contours, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. The effects are largely concentrated in the daylit hemisphere because of high daytime ionospheric conductivities.
