"Denudation" Quotes from Famous Books
 ... the almost lurid light of such an indictment, would be that if these things are left out, everything is left out. The American knows that a good deal remains; what it is that remains—that is his secret, his joke, as one may say. It would be cruel, in this terrible denudation, to deny him the consolation of his national gift, that "American humour" of which of late years ...

... in the neighborhood, but rather of exposure to the action of the elements. Not only are the walls in a very poor condition, but also the floors show, from the absence of dry soil upon them, that the whole ruin has suffered greatly from the same denudation. There are no fragments of pottery about it, and small objects indicating former habitation are also wanting. A cedar had taken root where the floor once was, and its present great size shows considerable ...

... rapid, as in cold, wet climates, and rough topography, or as in the case of glaciation of the Lake copper deposits, denudation follows close on the heels of alteration, and the surface is so rapidly removed that we may have the primary ore practically at the surface. Flat, arid regions present the other extreme, for denudation is ...

... clay, carry away this and the accompanying quartz and mica, and deposit them in separate beds, fluviatile and marine. When the exposed land consists of several unlike kinds of sedimentary strata, or igneous rocks, or both, denudation produces changes proportionably more heterogeneous. The formations being disintegrable in different degrees, there follows an increased irregularity of surface. The areas drained by different rivers being differently constituted, these rivers carry down to the sea different combinations ...

... during those days at the canon of the geology of my native hills amid the Catskills, which show the effects of denudation as much older than that shown here as this is older than the washout in the road by this morning's shower! The old red sandstone in which I hoed corn as a farm-boy dates back to Middle Palaeozoic time, ...

... eminent English authority and declared to be proved, "first, by the present river systems being of subsequent date, sometimes cutting through them and their superincumbent lava-cap to a depth of two thousand feet; secondly, by the great denudation that has taken place since they were deposited, for they sometimes lie on the summits of mountains six thousand feet high; thirdly, by the fact that the Sierra Nevada has been partly ...

... igneous origin, and "are believed by Mr. Fergusson to have been votive offerings." These masses, of what Sir A. C. Ramsay calls "tough and intractable silicious stone," have been, he says, "left on the ground, after the removal by denudation of other and softer parts of the Eocene strata." We subsequently saw several of these "grey wethers" in the grounds of Cobham Hall, and we noticed small masses of the same stone in situ in Pear Tree Lane, near ...

... 1200 to 1500 feet above the Ganges valley, and I have no doubt was deposited in very deep water, when the relative positions of these mountains to the Ganges and Soane valleys were the same that they are now. Like every other part of the surface of India, it has suffered much from denudation, especially on the above-named mountains, and around their bases, where various rocks protrude through it. Along the Ganges again, its surface is an unbroken level between Chunar and the rocks of Monghyr. The origin of its component mineral matter must be sought in the denudation of the ...

... That such a denudation actually occurred is of course within the bounds of geological possibility, if we take the precaution to date the incident far enough back, to remote and prehistoric days. There is little credence to be attached to the local traditions, which affirm that ...

... rid of it.... In 1896, Professor Shaler, than whom no one has spoken with greater authority on this subject, estimated that in the upland regions of the States South of Pennsylvania, three thousand square miles of soil have been destroyed as the result of forest denudation, and that destruction was then proceeding at the rate of one hundred square miles of fertile soil per year.. .. The Mississippi River alone is estimated to transport yearly four hundred million tons of sediment, or about twice the amount of material to be excavated from the Panama Canal. This material ...
