from the vapours that the Sunne elevates here below to the height in the middle Region of the Aire, from thence to water the earth. But neither the slime, nor the sand, nor the clay on the other side, are not each by it selfe, nor reduced together, are this virgin and pure earth, that is shut up in the Center of all the composed Elements, that is to say, in the bottome of them, for that produceth nothing, because it is incorruptible: and that which cannot corrupt, cannot produce any thing that should be subject to corruption; as we see in Fire, Salt, and Sand, which are of the nature of Glasse, all substances not onely incorruptible for their respect, but which preserves from corruption, that wherewith they are mingled; witnesse herbs, fruits, flesh, fish, and other the like, which being salted or buried in Sand are thereby kept the longer. And in _Mummies_, of those that remaine choked and buried in the Sands passing the Deserts, which are preserved whole many suits of yeares, even as well, nay better then if they had been enbalmed. So that this earth is formed of two incorruptible substances, Salt, and Sand, by meanes of the water which is thereupon congealed; as wee see in this faire Crystalline Glasse, made of Salt, of glasse wort, amongst which they mingle sand to retaine it; otherwise, in the great sharpnesse of fire that it must indure, to worke therewith, it would all vanish into smoake; wee depure and refine it afterwards in cleare Crystalline, joining thereunto _perigort_, or _sinople_ made of Lead. Their are some that carry their Sand with them, as _Foulgere_, _Charme_, or _Fouteau_, firebrakes, charme, or beech, and some others.
