While in Campania the burning of the earth makes ashes, in Tuscany the combustion of the stone makes carbuncular sand. Both are excellent in walls but one is better to use for buildings on land, the other for piers under salt water.

Chapter VI, Sec. 6Vitruvius
The reason why lime makes a solid structure on being combined with water and sand seems to be this: that rocks, like all other bodies, are composed of the four elements. Those which contain a larger proportion of air, are soft; of water, are tough from the moisture; of earth, hard; and of fire, more brittle. Therefore, if limestone, without being burned, is merely pounded up small and then mixed with sand and so put into the work, the mass does not solidify nor can it hold together. But if the stone is first thrown into the kiln, it loses its former property of solidity by exposure to the great heat of the fire, and so with its strength burnt out and exhausted it is left with its pores open and empty. Hence, the moisture and air in the body of the stone being burned out and set free, and only a residuum of heat being left lying in it, if the stone is then immersed in water, the moisture, before the water can feel the influence of the fire, makes its way into the open pores; then the stone begins to get hot, and finally, after it cools off, the heat is rejected from the body of the lime.

In walls of masonry the first question must be with regard to the sand, in order that it may be fit to mix into mortar and have no dirt in it. The kinds of pitsand are these: black, gray, red, and carbuncular. Of these the best will be found to be that which crackles when rubbed in the hand, while that which has much dirt in it will not be sharp enough. Again: throw some sand upon a white garment and then shake it out; if the garment is not soiled and no dirt adheres to it, the sand is suitable.
Vitruvius
With the present importance of the city [of Rome] and the unlimited numbers of its population, it is necessary to increase the number of dwelling-places indefinitely. Consequently, as the ground floors could not admit of so great a number living in the city, the nature of the case has made it necessary to find relief by making the buildings high. In these tall piles reared with piers of stone, walls of burnt brick, and partitions of rubble work, and provided with floor after floor, the upper stories can be partitioned off into rooms to very great advantage. The accommodations within the city walls being thus multiplied as a result of the many floors high in the air, the Roman people easily find excellent places in which to live.
Vitruvius
There's only three major elements. Air, land, which is your flesh and water, which is your blood. You're walking on a third of yourself. She's called Mother Earth. She gave birth to your ass. Ashes to ashes, dust to dust, your maggot food ass going right back to her!

Class, conservatives insist, is not really about money or birth or even occupation. It is primarily a matter of authenticity, that most valuable cultural commodity. Class is about what one drives and where one shops and how one prays, and only secondarily about the work one does or the income one makes. What makes one a member of the noble proletariat is not work per se, but unpretentiousness, humility, and the rest of the qualities that our punditry claims to spy in the red states that voted for George W. Bush. The nation’s producers don’t care about unemployment or a dead-end life or a boss who makes five hundred times as much as they do. No. In red land both workers and their bosses are supposed to be united in disgust with those affected college boys at the next table, prattling on about French cheese and villas in Tuscany and the big ideas for running things that they read in books.
