... the very edge, peering out and down through a green screen. A couple of hundred feet in length and width, it was half of that in depth. Possibly because of some fault that had occurred when the knolls were flung together, and certainly helped by freakish erosion, the hole had been scooped out in the course of centuries by the wash of water. Nowhere did the raw earth appear. All was garmented by vegetation, from tiny maiden-hair and gold-back ferns to mighty redwood and Douglas spruces. These great trees even sprang out from the ...

... the Andes consist of huge parallel chains with river and lake-basins of profound depth between them. In Mexico the same formation must have existed, but the basins have been filled up by material discharged from volcanoes and from the erosion of the mountains themselves, doubtless caused by the severe and sudden rain-storms and rapid changes of temperature characteristic of these regions. Thus the great plateau may be likened to a number of filled-up troughs, through whose ...

... horizontality so often remarked amidst gypseous and calcareous mountains, in the position of grottoes communicating with each other by passages. This almost perfect horizontality, this gentle and uniform slope, appears to be the result of a long abode of the waters, which enlarge by erosion clefts already existing, and carry off the softer parts the more easily, as clay or muriate of soda is found mixed with the gypsum and fetid limestone. These effects are the same, whether the caverns form one long and continued range, ...

When the first one wore out, it was plugged, and the second vent opened. Then, to stop this "erosion," the obturating (sealing) primer came into use. It was like the common friction primer, but screwed into and sealed the vent. Early electric primers, by the way, were no great departure from the friction primer; the wires fired a bit of ...

If they cool off while below the surface, they form intrusive rocks, which may later be revealed by erosion. When magmas reach the surface red hot, they form extrusive rocks, such as volcanic rocks. Thus, granite is an igneous, intrusive rock; lava is an igneous, extrusive rock. (Notice how the type of rock tells its past history—if you ...

... originally formed them as parts of the delta. This mud resists the action of the river wonderfully. It is a kind of clay on which the eroding power of water has little effect. Were maps made, showing which banks and which islands are liable to erosion, it would go far to settle where the annual change of the channel would take place; and, were a few stakes driven in year by year to guide the water in its course, the river might be made of considerable commercial ...

... beneath the sea level glaciers and deserts and desert deposits alike must also disappear. Vegetation will clothe the earth, and marine life swarm in the shallow seas of the broadening continental shelf. Under the mantle of vegetation, mechanical erosion will be less, that is, the breaking up of rocks into small pieces without any very great change, but the rich soil will be charged with carbon dioxide, and chemical activity will still go on. Rivers will still contain carbonates, even though ...

... cut off on all sides save the west from the surrounding country by a beautiful ravine, through which the river Rummel flows. The plateau is 2130 ft. above sea-level, and from 500 to nearly 1000 ft. above the river bed. The ravine, formed by the Rummel, through erosion of the limestone, varies greatly in width—at its narrowest part the cliffs are only 15 ft. apart, at its broadest the valley is 400 yds. wide. At the N.E. angle of the city the gorge is spanned by an iron bridge (El-Kantara) built in 1863, giving access to the railway station, situated on ...

... effected. Everywhere a soft, spongy carpet of fallen leaves, ever increasing in thickness, is spread out, moistening and enriching the soil and conserving the waters of the increased rainfall. A thousand living springs of pure, sparkling water make glad the plains and valleys. The evils of flood, erosion and drouth are checked; the climate made more congenial; the value of both hill and mountain, as a source of wealth, ...

... remark, are basaltic, and therefore plutonic. An area, as large perhaps as Sussex, has been lifted up en bloc with all its living contents, and cut off by perpendicular precipices of a hardness which defies erosion from all the rest of the continent. What is the result? Why, the ordinary laws of Nature are suspended. The various checks which influence the struggle for existence in the world at large are all neutralized or altered. Creatures survive which would ...

... of the river are many benches and terraces of alluvium, varying in width from a few feet to several miles, and comprising all the cultivable land in the valley of the river. Since the Verde is a mountain stream with a great fall, its power of erosion is very great, and its channel changes frequently; in some places several times in a single winter season. Benches and terraces are often formed or cut away within a few days, and no portion of the river banks is ...

... band or sheath of comparatively soft metal larger than the bore; the gas then acting on the base of the projectile, forces the band through the grooves, sealing the escape, entering the projectile, and, to a great extent, mitigating the erosion of surface. This is, of course, universally known. It is also pretty generally known among artillerists that the effect of the resistance offered by the band or sheathing on the powder is to cause more complete combustion of the charge before the shot ...

... places after the timber has been cut off gullies and washes start in the old wheel ruts, log slides, etc., and these and other forms of erosion can best be prevented by leaving the brush on the ground, either laid in the incipient washes or scattered over the soil that is likely to wash. Brush burning destroys the valuable soil cover, and on the spots where the piles are burned the soil is loosened, which renders it even ...

... road surfaces. Such affections may be acute, as in some cases of spavin, but are usually inflammatory conditions that do not occasion serious disturbance when these affections become chronic. If the involvement persists with sufficient active inflammation, there may follow erosion of cartilage and incurable lameness. If extensive necrosis of cartilage takes place, the attendant pain will be sufficient to cause the animal to favor the diseased part and such immobilization enhances early ankylosis—nature's substitute for ...
