By what hath been said, the well-minded Reader will easily perceive what vast treasures are oft-times before his eyes, and through ignorance lie as yet unknown, and not used to advantage. What man knows God’s end, in producing to light such great Mysteries and Secrets of Nature, in this most filthy Dregs of the World? To give thereof a Reason, we will not tire our understanding, but give most humble thanks to God for such great mysteries that he hath revealed for the comfort of many men, and will pray unto him graciously to bestow on us his fatherly blessing, to the end that we may well use such great gifts so freely bestowed.
But now if any should be of the mind that it is wholly unnecessary, that this Art should be made publickly known, because that Gun-powder is made of Salt-petre, and that by Gun-powder many Cities and most strong holds are overthrown, and nothing is to be expected thencefrom, but Slaughters and Destruction: To such, I answer, That it was not for this end that I disclosed this most great and most profitable Art, that by its base abuse I might help on these horrid Calamities; but my aims have been chiefly at this, if haply any new Foreign Enemies should invade our most dear Country (which is a danger we seem not far off from) we might be able to receive them with like Arms or Weapons, and by a just defence drive away such a Calamity.
And withal, that those most thick and vast Woods being despoiled of their thickness, may not for the time to come be a shelter for Thieves and Robbers, as likewise for wild beasts, all which oftentimes do much mischief.
And farther, That many thousands of Men may get their Food and Rayment more Commodiously and more easily, and may make good Gold and Silver from the unprofitable Wood. For by means of this Art, thousands of moneys may be gotten in our German Countries, without any hurt to our Neighbour. Nor is it needful to cut down any great Tree, for the superfluous Branches or Loppings, and the shrubby briary Underwood which is all about the Trees, and doth chiefly afford a passage to the Stags, and hiding places to other hurtful Creatures, will be sufficient for this kind of use or imployment.
The other Trees that grow up aloft may be preserved to build Houses withal, which may be employed about Hunting: And besides, when the Trees are freed from that thickness, and have thereby a free access of Air, they will the more easily dilate their Boughs, and grow up taller. And then too, those wild Beasts that are profitable, will (when such vast deal of underwood or shrubbiness is taken away) meet with fatter pasture, and with more plenty of Grass, and escape by having a freer Course from the pursuing Woolves, which now they are letted from by those most thick Shrubs and Bushes. But yet if so be that in such places in which is such a deal of Wood, and to no man useful; a good part even of the great Trees should likewise be cut down, and used about this Artifice of ours; yet notwithstanding there would not arise to the Possessors thereof any loss, but much Profit; and when all’s done, there would be yet remaining a huge multitude of Trees. Consider I pray those most spacious Woods the Arduenne, Ottonick, Semane, and Bohemian Woods, and many others which the Countries in Germany are cloathed (or environed) with.
Can it be imagined, that they can at all be lessened by the Glass Furnaces, or the melting of Minerals and Metals.
These places that are one year bared by cutting down the Trees, you shall see in few years covered over again, by the benefit of nature, with new Trees; so that it cannot possibly be, that though even a very great many Presses should be used to press the Juices out; such a vast immenseness of Woods should be exhausted, and make any sensible diminution of the Wood.
But now, if any one shall believe these writings of mine, and shall, after the afore-mentioned way, set about the Concentration of Wine, or Corn, or Wood; I do faithfully affirm unto him, that I have in this Book openly proposed the very naked Truth, without any disimulation, and have not omitted any thing save the revealing of the Presses, which for certain causes I conceal.
And therefore I certifie every one, that I will not as yet divulge this most wonderful secret, of thus-boiling Nitre out of the Juices of Wood, or else I would have described the Press too. Besides, though a man should even see the Press, and know how to make it, and were ignorant of the purification and concentration of the Juices, he would not bring the Art to effect; so that, without my instruction, the work cannot so easily be made publickly known. And though this seems to be a thing so mean, yet this squeezing out of the Juices of Wood, is far beyond (or richer) than the operations on Wine or Corn. But I doubt not but that many, well considering of this unheard of, and very gainful Artifice, will begin to think whether or no good Nitre may not likewise be gotten out of other Subjects easie to come by. Now then I must methinks needs instruct these.
The common Fossile Salt, and Sea Salt may by the benefit of this Art, be also turned into Natural Nitre; but I judge it needless to speak more of this, for as much as that which I have already mentioned concerning the Wood seems abundantly enough. Breifly, God doth in all places set before our eyes His Omnipotency, where he gives not Wood, there vouchsafes He Stones and Bones, out of which Nitre may as well be extracted, by those that are skill’d in this Art, as it may out of other things. And where Fire is wanting, there is Water however. But I know that it is certain, and past all doubt, that by the certain experience of Art, plenty of good Nitre may be made out of Sea Water.
