Seite 801 - The Mystical Rose ; or, Mary of Nazareth, the Lily of the House of David. " I am the Rose of Sharon and the Lily of the Valley.
Seite 268 - All feel the assault of fortune's fickle gale ; Art, empire, earth itself, to change are doomed ; Earthquakes have raised to heaven the humble vale; And gulfs the mountain's mighty mass entombed ; And where the Atlantic rolls wide continents have bloomed.
Seite 218 - For we are presented in Auvergne with the evidence of a series of events of astonishing magnitude and grandeur, by which the original form and features of the country have been greatly changed, yet never so far obliterated but that they may still, in part at least, be restored in imagination. Great lakes have disappeared, — lofty mountains have been formed, by the reiterated emission of lava, preceded and followed by showers of sand and...
Seite 58 - We often said to ourselves, What clearer evidence could we have had of the different formation of these rocks, and of the long interval . which separated their formation, had we actually seen them emerging from the bosom of the deep ? We felt ourselves necessarily carried back to the time when the schistus on which we stood was yet at the bottom of out.
Seite 2 - The term stratum means simply a bed, or any thing spread out or strewed over a given surface ; and we infer that these strata have been generally spread out by the action of water, from what we daily see taking place near the mouths of rivers, or on the land during temporary inundations. For, whenever a running stream charged with mud or sand, has its velocity checked, as when it enters a lake or sea, or overflows a plain, the sediment, previously held in suspension by the motion of the water sinks,...
Seite 163 - ... and denuding operations. Secondly; a gradual submergence then took place, bringing down each part of the land successively to the level of the waters, and then to a moderate depth below them. Large islands and bergs of floating ice came from the north, which, as they grounded on the coast and on shoals, pushed along all loose materials of sand and pebbles, broke off...
Seite 306 - When we have once arrived at the conviction that the numraulitic formation occupies a middle place in the Eocene series, we are struck with the comparatively modern date to which some of the greatest revolutions in the physical geography of Europe, Asia, and northern Africa must be referred. All the mountain chains, such as the Alps, Pyrenees, Carpathians, and Himalayas, into the composition of whose central and loftiest parts the nummulitic strata enter bodily, could have had no existence till after...
Seite 424 - ... was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava which everywhere form the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.
Seite 390 - The regular and uniform preservation of this thin bed of black earth over a distance of many miles, shows that the change from dry land to the state of a freshwater lake or estuary, was not accompanied by any violent denudation, or rush of water, since the loose black earth, together with the trees which lay prostrate on its surface, must inevitably have been swept away had any such violent catastrophe taken place.
Seite 489 - There is no possibility of the least intermixture of earthy matter in such cases. Thus, in the large submerged tract called the " Sunk Country," near New Madrid, forming part of the western side of the valley of the Mississippi, erect trees have been standing ever since the year 1811-12, killed by the great earthquake of that date ; lacustrine and swamp plants have been growing there in the shallows, and several rivers have annually inundated the whole space, and yet have been unable to carry in...
