Page 262 - The strongest houses were caused to vibrate to their foundations, and the surface of the very earth trembled as the destroyer raged over it. No thunder was at any time distinctly heard.
Page 116 - ... to the eye, and heaped up in enormous ridges running parallel to each other from north to south, undulation after undulation, each swell two or three hundred feet in average height, with slant sides and rounded crests furrowed in every direction by the capricious gales of the desert. In the depths between the traveller finds himself as it were imprisoned in a suffocating sand-pit, hemmed in by burning walls on every side ; while at other times, while labouring up the slope, he overlooks what...
Page 263 - ... the whole face of the country was laid waste ; no sign of vegetation was apparent, except here and there small patches of a sickly green. The surface of the ground appeared as if fire had run through the land, scorching and burning up the productions of the earth ; the few remaining trees, stripped of their boughs and foliage, wore a cold and wintry aspect; and the numerous seats in the environs of Bridgetown, formerly concealed amid thick groves, were now exposed and in ruins.
Page 115 - On the interminable sands and rocks of these deserts no animal — no insect— breaks the dread silence ; not a tree nor a shrub is to be seen in this land without a shadow. In the glare of noon the air quivers with the heat reflected from the red sand, and in the night it is chilled under a clear sky sparkling with its host of stars.
Page 242 - A deep precipitous valley below us, at the bottom of which I had seen one or two miserable villages in the morning, bore in the evening a complete resemblance to a beautiful lake ; the vapour which played the part of water ascending nearly half way up the sides of the vale, and on its bright surface trees and rocks being distinctly reflected. I had not been long contemplating this phenomenon, before a sudden storm came on and dropped a curtain of clouds over the scene.
Page 123 - Alani, and Usuni, — have shaken the world. As in the course of past ages, early intellectual culture has come like the cheering light of the sun from the East, so, at a later period, from the same direction barbaric rudeness has threatened to overspread and involve Europe in darkness. A brown pastoral race, (* ') of Tukiuish or Turkish descent, the Hiongnu, dwelling in tents of skins, inhabited the elevated Steppe of Gobi. Long terrible to the Chinese power, a part of this tribe was driven back...
Page 261 - ... from the north-west and intermediate points. The upper regions were from this time illuminated by incessant lightning ; but the quivering sheet of blaze was surpassed in brilliancy by the darts of electric fire which were exploded in every direction. At a little after two, the astounding roar of the hurricane, which rushed from the north-west, cannot be described by language.
Page 463 - I made me great works; I builded me houses; I planted me vineyards: I made me gardens and orchards, and I planted trees in them of all kind of fruits: I made me pools of water, to water therewith the wood that bringeth forth trees...
Page 261 - August, the tempestuous rage of the wind increased ; the storm, which at one time blew from the north-east, suddenly shifted from that quarter, and burst from the north-west and intermediate points. The upper regions were from this time illuminated by incessant...
Page 276 - ... every instant higher and higher into the sky, and casting longer shadows athwart the rocks; and out of the pale blue of the horizon you will see forming and advancing a troop of narrow, dark, pointed vapours, which will cover the sky, inch by inch, with their grey network, and take the light...
