Some of them were distinctly glaciated even belong the tide-line, the effects of wave washing and general weathering being scarce appreciable as yet. Some of the larger islets had a few trees, others only grass. One looked in the distance like a two-masted ship flying before the wind under press of sail.
Up to this point, nothing could have been more unlike the scenery which I had so far found to be associated with glacières; but now the country became slightly more Jurane, and limestone precipices on a small scale rose up on either hand, decked with the corbel towers which result from the weathering of the rock.
Cape Horn, Cape Horn a horn indeed, that has tossed many a good ship. Was the descent of Orpheus, Ulysses, or Dante into Hell, one whit more hardy and sublime than the first navigator's weathering of that terrible Cape? Turned on her heel by a fierce West Wind, many an outward-bound ship has been driven across the Southern Ocean to the Cape of Good Hope that way to seek a passage to the Pacific.
When granite is dissolved by weathering, carbon unites with the potash, the soda, the lime, the magnesia, and the iron, and turns them into carbonates and swells their bulk. The one thing that is passed along from formation to formation unchanged is the quartz sand. Quartz is tough, and the sand we find to-day is practically the same that was dissolved out of the first crystalline rocks.
Perhaps a half mile out, a lone human figure had just emerged from the water and propped itself gracefully atop a tiny islet, a mere rock at the edge of the continental shelf, which had somehow survived the weathering of the years. At least it looked human.
Mortimer noted her sparkling glances which took in everything, and went out of her way to show Saxon around, doing it under the guise of gleeful boastings, stating the costs of the different materials, explaining how she had done things with her own hands, such as staining the doors, weathering the bookcases, and putting together the big Mission Morris chair.
The great lava sheets thus produced are generally more or less amorphous, vesicular and amygdaloidal, often exhibiting the globular concentric structure, and weathering rapidly to a kind of ferruginous sand or clay under the influence of the atmosphere.
Suddenly a slight noise brought me to a halt. I listened intently. Only an indistinct rattling of small rocks disturbed the impressive stillness. It might have been the weathering that goes on constantly, and it might have been an animal. I inclined to the former idea till I saw Satan's ears go up.
These processes are known as METAMORPHISM, and the rocks affected, whether originally sedimentary or igneous, are called METAMORPHIC ROCKS. We may contrast with metamorphism the action of external agencies in weathering, which render rocks less coherent by dissolving their soluble parts and breaking down their crystalline grains.
She had always owned a good houseful of furniture; but, after making bitter meals upon the gradual wreck of it, she had been compelled to break up that house, and retire with her five children to lodge with a lone widow in this little cot, not over three yards square, in "Seed's Yard," one of those dark corners into which decent poverty is so often found now, creeping unwillingly away from the public eye, in the hope of weathering the storm of adversity, in penurious independence.
