 ... he dropped down a hillside to the southeast exposure. Here, poised above a big forested canon, and looking out upon Sonoma Valley, was a small farm-house. With its barn and outhouses it snuggled into a nook in the hillside, which protected it from west and north. It was the erosion from this hillside, he judged, that had formed the little level stretch of vegetable garden. The soil was fat and black, and there was water in plenty, for he saw several ...

The stranded bergs on the moraine bar at the mouth of Sum Dum Bay looked just as they did when I first saw them ...

The rock is gneiss, of a kind that is not easily disintegrated or eroded, nor is there any evidence of any convulsive movement.

... sir," said Master Sean with infinite patience. "This gun or any other gun in general, if you see what I mean, sir. It's even harder to place the ownership of a gun. Most of the wear on a gun is purely mechanical. It don't matter who pulls the trigger, you see, the erosion by the gases produced in the chamber, and the wear caused by the bullet passing through the barrel will be the same. You see, sir, 'tisn't relevant to the gun who pulled its trigger or what it's fired at. The bullet's a slightly different ...

It is obvious that the valleys are due mainly to erosion, that the Maderaner valley has been cut out of the crystalline rocks s, and was once covered by the Jurassic strata j, which must have formerly passed in a great arch over what ...

... of judicial review as to the substantiality of the factual justification of a professed exercise by a State legislature of its police power; and in the case of legislation affecting the remedial rights of creditors, it still affords a solid and palpable barrier against legislative erosion. Nor is this surprising in view of the fact that, as we have seen, such rights were foremost in the minds of the framers of the clause. The court's attitude toward insolvency laws, redemption laws, exemption laws, appraisement laws and the like has always ...

Deprived of mountain chains, on whose declivities the gradations of vegetable forms and the scale of the diminishing heat of the atmosphere appear to be picturesquely reflected — furrowed ony here and there by valleys of erosion, formed by the force of fresh water moving on in gentle undulations, or by the accumulation of detritus, resulting from the action of currents of water — continents would have presented no other appearance from pole to pole ...

... subject to convulsion and upheaval. The stratified rock lies horizontally just as it was laid down in the bottom of the Devonian Seas millions of years ago. The mountains and the valleys are the result of vast ages of gentle erosion, and gentleness and repose are stamped upon every feature of the landscape. The hand of time and the slow but enormous pressure of the great continental ice sheet have rubbed down and smoothed off all sharp angles, giving to the mountains their long sweeping lines, to the hills their ...

... described as an alternation of lofty bluffs and sinuous ravines,—the former known as "divides," the latter as "draws." The top of these divides preserves one general level,—leading naturally to the hypothesis that all the draws are valleys of erosion in a tract of alluvial deposit originally uniform with the plateaus of the divides. Some of the larger draws still serve as the channels of unfailing streams; most of them carry more or less water during the rainy season; few of them are dry all the year round. The river-bottoms which traverse ...

"They represent the detritus of pre-existing lands, the washings of rain, rivers, coast-currents, and other agencies of erosion; and since the areas supplying the waste could scarcely have been of less extent than the new strata it formed, it is reasonably inferred that land masses of continental magnitude must have occupied the region now covered by the North Atlantic ...

... with gleaming chalk-pits, and netted with roads of almost equal whiteness, continues to the great headland of Flamborough, where the sea frets and fumes all the summer, and lacerates the cliffs during the stormy months. The masses of flinty chalk have shown themselves so capable of resisting the erosion of the sea that the seaward termination of the Wolds has for many centuries been becoming more and more a pronounced feature of the east coast of England, and if the present rate of encroachment along the low shores of Holderness is continued, this accentuation will become ...

... 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 ...

... materials. They come from magmas—molten mixtures of minerals, often containing gases. They come from deep below the surface of the earth. 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 know ...

According to the map, that historic, first landing-place would be anything but a landing-place to-day; for figure "25" (that was it) stood well out in the river. The loss by erosion had been great along that part of the shore since those first settlers arrived. But even though the landing-place could not be seen, one could look out on the waters anyway and see ...

... But it's a devil of a job to estimate the age of anything here; things weather so slowly that most of the buildings might have been put up yesterday. No rainfall, no earthquakes, no vegetation is here to spread cracks with its roots—nothing. The only aging factors here are the erosion of the wind—and that's negligible in this atmosphere—and the cracks caused by changing temperature. And one other agent—meteorites. They must crash down occasionally on the city, judging from the thinness of the air, and the fact that we've seen ...
