Sometimes it remains friable and chalky, but, more often, the infiltration of water, charged with carbonic acid, dissolves some of the calcareous matter, and deposits it elsewhere in the interstices of the nascent rock, thus glueing and cementing the particles together into a hard mass; or it may even dissolve the carbonate of lime more extensively, and re-deposit it in a crystalline form.
But chambers thus excavated were apt to collapse, especially if the rock was of the soft and friable nature so common in Phoenicia Proper and in Cyprus; on which account, in such soils, the second kind of tomb was preferred, sepulchural chambers being solidly built, either singly or in groups, each made to hold a certain number of sarcophagi.
Also, will it pay to put it on a large field of alfalfa? The land is adobe. I can get slaked lime for the hauling, distance being about five miles. The lime will make the land more friable and, therefore, less disposed to bake and lose moisture by evaporation. Alfalfa is hungry for lime and is generally advanced by the application of it. Fertilizing Alfalfa. Can new cow manure be put on alfalfa?
It is true that asphaltum papers will always in a fresh state contain a small percentage of volatile ingredients, which after a while make it hard and friable upon the roof; but, by reason of its greater percentage of resinous components, it will always preserve a superior degree of durability and become far less porous. One hundred parts by weight absorb 140 or 150 parts by weight of coal tar.
Some of these layers of shells rested on a thick bed of bright-red, dry, friable earth, capping the surface of the tertiary sandstone, and extending, as I observed whilst sailing along the coast, for 150 miles southward: at Valparaiso, we shall presently see that a similar red earthy mass, though quite like terrestrial mould, is really in chief part of recent marine origin.
Only centuries of habitation and cultivation could have changed the three feet of surface soil in Blackbanks from a stiff unworkable clay to a black friable garden mould, and it is probable that the British occupation had lasted for a very long period before the Romans took possession.
The sal forests in North Bhaugulpore generally keep to the high ridges, which are composed of a light, sandy soil, very friable, and not very fertile, except for oil and indigo seeds, which grow most luxuriantly wherever the forest land has been cleared. In the shallow valleys which lie between the ridges rice is chiefly cultivated, and gives large returns.
What no merits of his could give, the land which he had chosen gave, Mesopotamia pretty soon proving herself a treasury of mineral riches: here is bdellium and the onyx- stone; and where the streaming Pison, dawdling, draws his twine of waters over that happy valley of Havilah, there is gold hoard stored from before the Eozoic, as misers bury for their heirs, in mine and friable quarry, rollick rain: "and the gold of that land is good".
The impression of walking for miles by taper-light between those close walls of brown friable stone, or that soft dusty ground, in a warm vague stifling air; the monotonous rough sides, the monotonous corners, the widenings in and out of little Galla Placidia-like crypts, with rough hewn pillars and faded frescoes; of the irregularly cut pigeon-holes, where bits of bone moulder, and the brown earth seems half composed of bone.
We found variation here 2 degrees 15 minutes east. When the sea was smooth by the land-winds we sent our boats ashore for water; who, in a few turns, filled all our casks. The land here is low, swampy and woody; the mould is a dark grey, friable earth.
