To produce a ton of potash, the trees on an acre of ground would be cut down and burned, the ashes leached, and the lye evaporated in great iron kettles. A ton of potash was worth about twenty-five dollars. Nothing could show more plainly the relative value of money and human labor in those early times. Two more patents were issued during the year 1790.
Is it not more rational to suppose with Richthofen that these are related as cause and effect, rather than that cold water has leached the ore and the silica from the walls near the surface? Mr.
Then they leached it, pouring water on it in improvised tubs, and dissolving the niter. This solution they boiled down and the residuum was saltpeter or gunpowder, without which no settlement in Kentucky could exist. The little valley now became a scene of great activity. The fires were always burning and sack after sack of gunpowder was laid safely away in a dry place.
I can buy goat manure from an inclosure where this is deposited to an amount of about five carloads. Will goat manure be of great value in fertilizing an orchard? If so, how much of it should be spread an an acre? Accumulations of sheep and goat manure in a dry situation, that is, where not leached out by heavy rainfall, have been found to run as high as $13 per ton in fertilizing constituents.
The ashes from the house and the log-heaps were either leached at home, and the lye boiled down in the large potash kettles of which almost every farmer had one or two and converted into potash, or became a perquisite of the wife, and were carried to the ashery, where they were exchanged for crockery or something for the house.
The effort to stimulate late summer growth by cultivation and fertilization is all wrong; use manures and fertilizers freely from March until early June, but not later. The fall mulch of manure, if used, is more for warmth than for fertility; it is a blanket for the roots, but much of its value is leached away by the suns and rains of winter.
But this was not corn, and so it was safe from such enemies as he. You may wonder what his rigmarole, his amateur Paganini performances on one string or on twenty, have to do with your planting, and yet prefer it to leached ashes or plaster. It was a cheap sort of top dressing in which I had entire faith. What lessons he got in botany in the hoeing!
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.
Many of the richest ore deposits are thus due to successive concentrations: the ores were leached originally from the rocks to a large extent by laterally seeping waters; they were concentrated in the ore deposits of the vein chiefly by ascending currents; they have been reconcentrated by descending waters in the way just mentioned.
In its presence the insoluble iron oxides which give color to most red and yellow rocks are decomposed, leaving the rocks of a gray or bluish color, and the soluble iron compounds which result are readily leached out, effects seen where red or yellow clays have been bleached about some decaying tree root.
