Wood ashes long exposed to rain lose most of their valuable contents, and leached ashes are only of small value. If they are fresh ashes or ashes which have been kept dry, they are chiefly valuable for potash, which is good in its way, but not all that a plant needs.
A granite mountain does not crumble with alacrity, but once resolved to soil makes the best of it. Every handful of loose gravel not wholly water leached affords a plant footing, and even in such unpromising surroundings there is a choice of locations. There is never going to be any communism of mountain herbage, their affinities are too sure.
Fissure Veins. Sheets of metalliferous matter filling fissures caused by subterranean force, usually in the planes of faults, and formed by the deposit of various minerals brought from a lower level by water, which under pressure and at a high temperature, having great solvent power, had become loaded with matters leached from different rocks, and deposited them in the channels of escape as the pressure and temperature were reduced.
You know he thinks he's a mining expert, and he's been crazy to look at the diamond drill cores; and the other day the boss driller was over and he told me how he got rid of him. You know, in drilling down they run into cavities where the lime has been leached away, and in order to keep the bore intact they pour them full of cement.
On the planks beneath his shoulder-blades, where his feet had come and gone for forty years, all leached and whitened by the strong lye of countless scrubbings at the hands of the old wife and the new, his blood ran down in a little stream. It gathered in a cupped and hollowed plank, and stood there in a little pool, glistening, black.
Ore deposits confined to a single bed or formation of limestone, of which the joints, and sometimes planes of bedding, enlarged by the solvent power of atmospheric water carrying carbonic acid, and forming crevices, galleries, or caves, are lined or filled with ore leached from the surrounding rock, e.g., the lead deposits of the Upper Mississippi and Missouri. Segregated Veins.
Winter snows, summer fogs and rains have washed the hillsides clean; they are leached out and they present a lifeless, forbidding front to travelers. In many places the granite fragments which still encumber them lie piled one above another in such titanic chaos as to discourage man's puny efforts to climb over them. Nevertheless, men have done so, and by the thousands, by the tens of thousands.
When these rocks were upheaved and subjected to weathering, their iron compounds were decomposed. Their iron was leached out and carried away to be laid in the Algonkian water bodies in beds of iron carbonate and other iron compounds. During the later ages, after the Algonkian strata had been uplifted to form part of the continent, a second concentration has taken place.
Many of the available tracts were so narrow that the cost of embankment was very high in proportion to the area secured; and hurricanes from oceanward sometimes raised the streams until they over-topped the banks and broke them. If these invading waters were briny the standing crop would be killed and the soil perhaps made useless for several years until fresh water had leached out the salt.
The latter put her arms about her friend's neck and kissed her. The princess threw a wide cloak over the young girl's shoulders and drew the hood over her head. "Let us be quick," said Corona, repeating Gouache's words. They walked quickly away in silence, and no one spoke until they leached the Palazzo Montevarchi.
