Chapter XLVII: Front Matter (47)

But now that the certainty of the thing may be the more apparent, and that no body may think it a fable, that Salt-petre may be extracted out of stones, we will shew some places in which Salt-Petre lies in the stones in a most plenteous manner: And although that there are sundry such places that offer themselves unto us, where the stones contain Salt-petre in them, we will demonstrate the verity of this in those places we have lived in, for ’tis impossible for us expresly to pronounce such or such a Mountain in this or that Country full of Salt-Petre, which places we never saw. ’Tis not given us to search all places of the Earth, but such places as we have seen and come to, we have left but few things in them untoucht, whose nature we have not throughly examined.

Therefore for Examples sake, we will take some part out of our own Country, and exhibit or shew unto all Men, those stones which are therein found to participate of Salt-petre, any one that is studious in these affairs may do the same in other places, and make a diligent inquiry into them, and he will find that almost all Mountains are filled therewith, and yet is known to none or at least-wise to but a very few. In _Francia_, (or _Franconia_) and indeed at _Kitzing_ where I dwelt before I came to _Holland_, I often went into the Field in clear weather, with an intent to search out Minerals, and although that sundry Men ignorant of (such) businesses, do report that there are not any Minerals at all to be found in _Franconia_, and that never any Veins of Gold or any other Metal have been found there, because all the Inhabitants do live contentedly with the plentiful provenue of Wine and Corn; nor do they labour about finding out any other Treasures (for there is not any Country in all _Germany_ in which is gathered more abundance of Wine, and of a better sort, than in _Franconia_ aforesaid; which gathering of Wine is to be accompted to the _Franks_ or _Franconians_ instead of Mine-pits, and yield them imployment enough) yet nevertheless forasmuch as my mind was ever bent that way, and I was naturally inclined to search very inwardly into those things which offer themselves unto us, amongst the wonderful works of the most great and glorious God, I could not omit the visiting such places, which seemed to all Men as unfit for bringing forth Minerals, and which were judged to be clearly void of the same, as being willing to try whether or no some things that others knew not of might not offer themselves unto me. Nor was my hopes in vain, for I found far more than my expectation was, and if necessity required I could shew those very places.

But forasmuch as I have proposed to my self, here to shew such places only in which Salt-petre may be plentifully made, I will at this time pass by the other Minerals in silence: Yet so, as not wholly to leave such things, as offer themselves in the way, untoucht. I will therefore take in hand some part of the _Rhine_, which is between _Kitzing_ and _Aschaffenberg_, and will very briefly (for my purpose is not to write a Chronicle) shew what treasures the most Great and Blessed GOD hath vouchsafed unto those places, besides Wine and Corn so plentifully abounding there.

_Kitzing_ is an Eminent I own and well built, belongs to the Bishoprick of _Wurtsburg_, and is founded upon Lime-stone, and therefore the soil is very fruitful; and yields Wine and Corn in abundance. But as soon as ever we are past over the Bridge of the _Mhene_, the Earth begins to be sandy, and has abundance of Flints in it, which contain in them some Gold as well as Iron. The manner of extracting it is described in the second Part of the _Prosperity of Germany_, and is confirmed in this third Part.

About a mile distance opposite to the said City is situated an high Mountain, very full of huge Trees, in this Mountain are various Castles (or Houses) the chief of which is the _Cossel_ Castle, which is the House belonging by succession to the Lords of the County _de Cossel_: At the bottom of the Mountain there is a Village of the same name, belonging to the said Castle (or Palace.) In this Village there are abundance of Springs, the Waters of most of them I have often times tasted, and have perceived them to be mightily impregnated with Salt-petre, insomuch that the Beasts do altogether shun the drinking of them, much less can Men use them about the boiling of their Victuals: Yet some of them yield sweet water very fit for domestick affairs. These Nitrous Fountains are of no use, nor do they effect ought, save that they drive some Mills, and run through the Village a particular way afore they fall into the _Mhene_.

And forasmuch as the aforesaid Earls have known that the chief part (or most part) of the said Fountains are wholesome by reason of the plenty of Salt-petre in them; they have therefore taken care to have a great House built, that so the place may be rendred commodious for those that by reason of some disease should come unto this place for the sake of washing their sick bodies; and there are abundance known to come, that are ill, in the Summer time, from places far remote; several of them too by a due using this Bath are restored to their former health.

They know not any other use of these nitrous Fountains than what is aforesaid; whereas if they did but know how to add some Virtues to the said waters by the benefit of the Juice of the wood, of which there is great store in that place, they would find by the use of them then, many wonderful effects in the curing of Diseases.

Being therefore earnestly intent upon the search hereof, _viz._ from whence these nitrous Waters should chiefly proceed, I found that the Mountain nigh that place, extending it self for some miles, was every where full of Salt-petre, and that it stuck in the Rocks themselves, out of which whatsoever is on the Mountain grew. I did therefore diligently search out, what condition those Stones were of, which the workmen dig’d out in these places, and I knew that there was a great quantity of Salt petre contained in them, insomuch, that as many Mountains as here (abouts) seem to be replenished with the same: Nay more, if you shall break one or two of those Stones with which the Houses of the Village of _Cossel_ are built, you shall find every where in them abundance of Salt-petre. I went to visit the place it self where those Stones are digged out, but found not any Salt-petre among the digging, because the Air had not as yet displaied its Virtues thereupon: But I observed that in those stones exposed a while to the Air, there was plenty of Salt-petre. He that would see it with his own Eyes, let him go into any House of the _Cossel_ Village, whose Walls are of ancient standing, and he shall find that there is abundance of Salt-petre in those stones, and withal, that the Pillars belonging to the Bath-house do yearly wax less, for as much as scalings of the thickness of the back of a Knife do still fall off, by the power of the separated Salt-petre, as I have often very accurately and curiously observed. If the Earls or Counts did but know the true use of this excellent and o cult Treasure, they would get far greater riches out of that bare Mountain only than by all the County. I doubt not but that seeing I have in this place detected this Treasure, there will some be found that will labour for their own profits sake to find it out.

Not far off from the said Mountain the whole Earth abounds with Iron, not in the form of Veins but of Reins, insomuch that the Metal of Iron offers it self in various particles or pieces of diverse magnitudes; for in some places it is found as big as an Hazle-nut, or an Acorn; in other places as big as an Egg, or ones Fist, yea and as big sometimes as ones Head, which by the force of the Fire is made facile and yields abundance of Iron; nor did I ever yet meet with any Metal of that sort more excellent than that is, but no body knows it, though it may be commodiously prepared or fitted for the use of Man, because there is in this place plenty enough of Wood and Water to be had [for such a purpose.]

This Mountain stretcheth out it self some miles, reaching as far as _Iphovia_, and the jurisdiction of the City of _Wurtzburg_; so that the chiefest and greatest part thereof is seated in the Bishoprick of _Wurtzburg_: And therefore might immense and vast Treasures be gotten, were there but such as were lovers of Art and would make themselves skill’d in the Operation.

Besides, this Mountain yields abundance of white and red Gypsum, which may be reduced to an exceeding whiteness by the force of the Fire.

Besides this too, we have known Marble and Alabaster digg’d out hence, and yet it has not been very durable, for it becomes nitrous after it hath lain exposed a while to the Air, and falls to powder, and yields plenty of Salt-petre, were it but rightly managed, for there’s no want of Wood here.

There is yet moreover found in the said Mountain another Castle which is called _Swansburg_, and belongs to the Bishoprick of _Wurtzburg_, where the Soldiers did heretofore use the Metallick Rods, to search after, and to see if they could find (by the using them) some Treasures; and they tried whether or no (the Castle being burnt by the occasion of the War) any such Treasures lay any where hidden. What they found I do not yet know: But this I know, that the said Rods did shew good Metal to be every where (thereabouts) The which thing gave occasion of explaining or unfolding the said matter in its proper places. Besides this, they digged up nothing else but such nitrous stones for some fathoms depth. I once viewed this place, and found that the stones extracted some years afore out of this Mountain were altogether brittle, and is a manifest token that the whole Mountain is fill’d with Salt-petre.

There is besides this Mountain, another nitrous one that I know of, of the like condition in the mid-way ’twixt _Kitzing_ and _Wernfeld_ (and is about a miles distance from _Carlstadt_) but that which is here had, differs from the former in this, _viz._ that the stones which it exhibits are of a red colour, nor are they so much impregnated with Salt-petre, as those of _Kitzing_ aforesaid, for they are richer in Petre, and are of a more ashy colour.

There are likewise such kind of stones also that they cut or dig forth at the _Mhene_ near the City _Rotenfeldt_, but they have not in them so much Salt-petre as those have that are found in the _Cossel_ and _Swansburg_ Mountain.

There’s abundance of such stones in several places in _France_, but my purpose is not to mention them all, for I was minded to mention such only as my self have seen, and that are near bordering upon the _Mhene_.

They that have a mind to deal with them may make their search, and they will find in all Countrys of the Earth fit stones for their purpose, the which we may hereby know, if being kept a while in the Air, they wax soft, and scale off in most thin leaves, and there sticks to your Fingers in rubbing them off, a reddish Meal.

Besides this too, you may have a most certain sign of such Petry places by those Spiders that have a small body and round, and long feet, for they stick to those stones in abundant measure: For such Spiders do not feed upon hearbs, grass, flies or other insects, but on old Walls, and they seat themselves chiefest of all on those aforesaid stones. They are not all venemous as the common house Spiders are, and therefore the Children do gather them, and are much delighted with them. Now they sticking on to the softer sandish stones do most certainly demonstrate that Salt-petre is contained in them; for tis that which they are nourished with, and conserve their life by, and this I was willing to signify unto you. But put case that no such nitrous stones were to be found, yet however there is not the opportunity denied us of making Salt-petre of the common Lime-making stones, and of them there is every where plenty enough, if they are calcined by the benefit of Wood, and made nitrous with the juice of wood.

What shall I say of the Calcined fæces of _Tartar_ which are yearly gathered up and thrown away in vast quantities, in all that tract which lies on the River _Mhene_, between _Bamberg_ and _Franckfort_, whereas notwithstanding some hundreds of hundreds weight of Salt-petre might be extracted thence-from, did they but mind it. For whatsoever Tartar is therein contained, is all of it Salt-petre when ’tis duly boiled with a Lixivium of Lime, and being hence strained, and a sufficient evaporation made, it be set by to Chrystallize. For it attracts the soul after a magnetick manner, which Operation if rightly instituted, there may be prepared thence from a most inflammable nitre in three days space, the which is likewise of far greater profit than the getting out the Tartar by the help of a Press, and with a great deal of labour; or else than the making Potashes, as we see usually done.

Besides too, there are found other stones that being burnt do yield abundance of Salt-petre, such as are the Tophi (or soft sandy stones) which may be abundantly gathered near _Triefelstein_, which is a Monastery situate on the _Mhene_, in other places of _Germany_ they make even whole Mountains: So that it is evident that there is no where any want of convenient matter to gather Salt-petre from, if Men would but set their hands to the work. These stones are obvious unto all; and who knows what Treasures the Woods (which we do not at all search into) abound withal? Would time permit me I could shew that various kinds of Metals are conserved in the Mountains situate between _Kitzing_ and _Franckfort_, and especially in the _Speshardensine_ (Mountain,) the disclosing of which, some other more commodious place will admit of.

Now follows what we mentioned of the aforesaid
LAZARUS ERCKER.

_Of the manner of Boiling =Salt-petre=._
AND FIRST
_By what means a Lixivium is to be made out of a Nitrous Earth_.

If you are minded to make a Lixivium of such an Earth, dig it as deep as you shall find by proving it to be either good or naught, especially if you intend to make it in great quantity, and keep it in a dry place. Then take care to have some great wooden Tubs, or Vessels made, so large, that each of them may hold about some ten Wheel-barrows full of the Earth, and whereby you may be able to prepare Lixivium enough, answerable to the work you have proposed to your self to do, and to the bigness of your Copper. Now there are commonly required for such a work, to one Copper Pan that weighs two hundred weight, eight Wooden Vessels which are to be placed in such order, that on each side there may stand four in a row, opposite to each other. These same Tubs are to be so far distant from the next Collateral Vessels, as is requisite for the Wheel-Barrow wherein the Earth is brought to come between: Yea, and it is necessary that there be half an Ell’s space betwixt the said Tubs and the Earth, or Ground, it self, whereon they are placed. Likewise, each of the Vessels, or Tubs, must have a hole in the fore-part, and towards the bottom thereof, fit to put in a Plug (or Tap) at: Then finally, there must be put under those Plugs, a long Vessel like a Channel-pipe, which may receive in it the Lixivium running out of the Tubs, and may guide it along into a peculiar Wooden Vessel, as into a common Store-house set in the Earth hollowed for that purpose, to receive the said Lee in.

All your Tubs being thus rightly ordered, put in upon every Tubs bottom another (false) wooden bottom, perforated with many Holes, and let it lie two Fingers breadth distant from the true bottom: Upon this (false) bottom lay yet another made of Bull-rushes, or your small sort of Reeds which grow plentifully in Ditches about the thickness of a quarter of an Ell: In want of these Reeds throw in upon the aforementioned perforated bottom, the quantity of a Span (thick) of Chopt Hay, or Straw, laying some very thin boards thereon, that so it may not be scattered (or float) abroad. And your Vessels are made compleatly ready.

Now then, put of the Earth you have already tried and gathered, as much into each of your Tubs, as they can hold, yet with this Caution, That the top part of your Vessel be empty a Spans heighth. And observe this, that if you can get some old ashes of the Curriers, or Soap-boilers, as much of it as two or three Wheel-barrows will carry, it must be put in upon the topmost (made) bottom of the Tub, afore the Earth, but now spoken of, be put in. At the top of the earth, lay a Cover made of Twigs, (or Withes) and fasten it with a wooden stick at the top of the earth. This done, pour common water upon the earth contained in the Vessel, an Hands breadth in heighth, so as that it may rather touch (or be poured) on the Twigs, than the Earth it self, least the said earth become unequal thereby, and hollowed in several places. Let it stand thus for eight hours, which time being overpast, draw your Plug out, and let the water you poured on, run out at the hole beneath, which as long as it is muddy, you must always pour in again into the Vessel, repeating this so often, till it comes out clear, then keep it, and this water is called a weak Lee or Lixivium.

This done, pour common water again upon the earth from which the Lee hath been already, once separated, that so it may extract the residue of the Lixivium out of the earth; and this Lee is of no use, save that it may be poured on upon new earth, instead of simple water; for it oftentimes doth even yet contain a great deal of Nitre, insomuch, that you may sometimes extract out of an hundred weight thereof, three or four pound of Nitre.

This Extraction being finished, take out the unprofitable earth out of the Vessel, and put in new; and continue the Operation, after the aforesaid manner, reiterating it so long, and so often, until you have gotten store enough of the Lixivium, that the work of boiling be not intermitted for want of Lixivium.

Besides, there must be some Wooden Vessel placed at the upper part of the Copper which this Lixivium is boiled in, out of which may run so much Lixivium into the Copper as is wasted away by boiling, that so there may be still kept the same order of boiling, and the same quantity of Lixivium in the Copper. This boiling is to be on this wise continued, until a Centenary, or hundred weight of Lixivium in the Copper, yields according to the less assay (or weight) twenty five pounds of Nitre; and this may be done in two Days, and one Night.

This being thus done, you must have ready yet two Tubs, or Vessels (more) of Wood, made after the afore prescribed manner, and furnished with a (false) perforated wooden bottom, besides its own bottom, and likewise with such a bottom as is made of Reeds (or Bull rushes); only you are to observe this here; That there must be put yet another perforated wooden bottom upon this topmost bottom of Reeds, upon which there must be first cast in some chop’d Straw, then some Ashes of Firr, Beach, or any other Tree, so much in quantity as may overtop the Straw an Ell or Cubit, [_Ulna_] high; or rather (if it may be had for a very mean price) as much as may fill the Tubs, or Vessels. But yet, these Ashes are not to be just simply thrown in (as they are) upon the Straw, but afore this is done, they must be first well mixt together, then moistened with some of the best hot Lixivium, that there may be made a Mass. Then when the Ashes are on this wise prepared, and put in the Vessel, the Lixivium boil’d to its heighth, and which yields in the proof twenty five pound, must be poured thereon, as hot as possibly it may, and is to be often drawn off by the lower hole, until (if troubled or muddy) it becomes clear.

After that all the Lee hath thus passed through the Ashes of both Tubs (the which is done upon this account, That all its fatness may pass into (or be left with) the Ashes, which Ashes are hereby rendred stronger to wash withal) keep it in a peculiar Vessel.

Then pour the common Lee or Lixivium upon the Ashes remaining in the Tubs, which when it hath passed through the Ashes, is called the second stronger Lixivium: Then again pour on yet a third time, hot Lixivium, and when ’tis drawn off, it is called the second weaker Lixivium: Lastly, the common Lee, or Lixivium, may be poured on cold upon the Ashes, that so all the virtue of the same may be wholly extracted.

* * * * *

The Figure before going (_Numb. 1._) will shew you the way of placing the Tubs, of preparing the Lixivium, and ordering the boiling.

A _Are the eight Wooden Tubs, wherein the earth is put_.

B _Channels, or Conveyances, by which the water runs into the said Tubs._

C _Channels, or Gutters, by which the Lixivium is conveyed into a Vessel set thereunder._

D _The Vessel in which the Lixivium is gathered, or received._

E _The little Vessel out of which the Lixivium runs into the Copper._

F _The Furnace._

G _The Copper._

H _The door of the Furnace whereby Wood is put in under the Copper._

I _The Lower Wind-draught (or Ash-hole) of the Furnace._

K _The inward shape of the Furnace._

L _An Iron Grate, which the Wood is put upon._

_The manner of preparing the Liquor, out of which =Salt-petre=
may be made by Boiling._

First of all, pour your second weaker Lixivium into your Copper, and set it a boiling, then let your second stronger Lixivium run thereinto by little and little; and then lastly, the first Lixivium it self, and which is the chiefest of all, until the Copper be almost filled, and the Lixivium be boil’d enough to shoot.

And now when you perceive that your Liquor is made strong enough by boiling, put in a Brass Ladle perforated (or full of holes) several times, even to the bottom of the Copper, and if the Lixivium lets fall out of it any Salt, you will find it at the bottom, the which you may take up with your Ladle.

Note also, That the Scum which at the end of this Boiling is plentifully gathered, must be carefully taken away: Now then try the readiness of your Lixiviums Crystallization, on this wise: Put either two or three drops on a cold Iron, or on a Polish’d Plate of Iron, and if it stands, or grows hard; that is, if when you turn the Iron up and down, it does not run (or flow) down, these are signs of the fitness of your Liquors Crystallization. Or else, you may put some of the Lixivium in a Brass Vessel, and set it in cold water, and so you shall see whether the Liquor be fitted enough to Crystallize; for assoon as ever the Lixivium shall be cold, there will be plenty of Salt-petre generated: Nay, even the very Brass Spoon it self denotes the goodness of the Liquor, it being put into the Liquor, and again taken out, it will show it sticking on it, as if it were Oil.

Out of a Centenary, or hundred weight of Liquor thus perfectly prepared, there will proceed more than seventy pound of Salt-petre.

_The way of rightly using the Liquor for the Generating of a more
Crude_ Salt-petre.

Pour your Liquor prepared after the afore-shown manner, out of the Copper into a narrow Tub, or Vessel, made of Firr, or Pine-tree wood; wherein let it remain quiet, till it be a little refrigerated, and the muddiness, or slimyness [_Limus_] appear, and you find that the salt sticks on in Granes to the sides of the Vessel; now when you perceive your Lixivium so cooled, as that you can put your finger thereinto without burning, pull out the Plug, wherewith an hole made in this long Vessel, about a span’s heighth from the bottom, was shut, or stopt, and so let the Liquor run forth, into very great Wooden Vessels, and deep, purposely made for such a business; or else into Copper Pans, buried almost (up to their Necks) in the earth, (for the cooler the place is, which they stand in, so much the better, and the more plenty of Salt-petre is gathered, and Crystallizeth) and you will find that your crude Salt-petre will shoot therein, the thickness of almost two fingers breadth, partly of a whitish colour, partly yellow, and partly blackish.

After that this boil’d Liquor hath stood for two days, and so many nights in the Vessel, the Lixivium of the Salt-petre which swims at top, must be taken away, which you may mix with the strong Lixivium, and pour a second time upon Ashes, for else the Lixivium will contract too much fatness, and there will be no Salt generated.

Sometimes it happens, that when the Ashes are not good, there’s no salt at all gathered in the Liquor, in which case there is no presenter Remedy, than to mix such a Lixivium stronger than is fit, with another, and so pour it again upon new, and good Ashes, and then let the boiling be again perfected after the afore-prescribed manner.

Likewise, when in the boiling you find the Lixivium very muddy, whereby the Collection of the Salt is oft-times hindred, it must be taken away, and let the Washer-Women, or Lawndresses have it, and other must be substituted in its room, and be farther purified by the help of Ashes.

* * * * *

The Figure signed (_Numb. 2._) shews the manner of preparing the
Liquor by boiling, and of extracting and gathering the Salt
thereout of.

A _Long narrow Tubs, or Vessels, in which the decocted Liquor of the Lixivium is cooled._

B _The Furnace wherein the Copper stands._

C _The Man that manageth the boiling, and extracts, or draws out the salt with a Ladle, the which he lays in a Withy Basket placed on the Copper, that so the Lixivium (in it) may again run down into the Copper._

D _The little Basket._

E _The little Tub out of which the strong Lixivium runs (by little and little) into the Copper._

F _Coolers, or Vessels, in which the Crude =Salt-petre= shoots._

G _Four Brass Pans put in the Earth, hollowed for the purpose, in which likewise the =Salt-petre= is generated (or shoots.)_

H _A strong Vessel whereinto the Lixivium remaining after the generating (or shooting) of the =Salt-petre=, is put._

_The way to purifie the Crude =Salt-petre=._

When all these things are thus done, and the Lixivium that swims at the top of the Salt-petre is taken away, lift up those Vessels, or Brass Pans, containing that salt, and turn them up and down in some convenient place, that so the residue of the Lixivium, that lies as yet in them may flow, or run clearly out, into another Vessel set thereunder.

This done, take the Salt-petre out of the Coolers, or out of the Coppers (or Brass Pans) with an Iron Spatula, or rather with such an Instrument as your Plasterers use (=eine telle=, a Truel) and put it in a Tub that has a hole in the bottom thereof, that so the Lixivium may be perfectly separated therefrom. They that sell that crude Salt-petre, and not at all purified, for the Salt-petre Boilers, do pour thereon pure (or clear) Well-water, by the means of which, it is made more white, that which is thencefrom separated they do again mix with other stronger Lixivium and so boil it up for the following use.

But if you have a mind to purifie this crude Nitre from its salt, and all its Impurities, that it may be rendred fair, and white, you are to proceed this following way:

Take almost as much Well-water as is sufficient for the dissolution of the Salt-petre, put it in the purifying Copper Vessel, first cleaned with water, and dried with a cloth, and put the fire under it, and make it most exceeding hot, then throw in your Salt-petre by little and little, and in pieces, continually stirring the Salt-petre that sticks at the bottom with a spoon, that it may be the easier, and sooner dissolved; this only is to be observed, that there is required a more gentle fire, while the Salt-petre is cast into the Copper, so as the water may be kept always hot. When all the Salt-petre is almost dissolved in the water, promote the boiling thereof, by augmenting the fire, then try if there be any salt in a (biggish) gross form, residing in the bottom of the Copper Vessel, which if you find to be, (for indeed, the Salt-petre it self is not so very easily dissolved, nor doth its being admixt in a more copious manner, at all benefit the Lixivium) take it forth with a Spoon, (or Ladle.)

This done, separate the Scum swimming at top of the boiling water, then have ready a Brass Vessel that will hold about ℥_j.ss._ of Liquor, fill it half full with the Lixivium, set the Vessel in cold water to cool, and you shall find your Nitre presently to Crystallize, or shoot therein.

Hereby may you try whether your Purgative water be strong enough, or not; for if it be stronger than is fit, you will find a little skin spread it self over the matter contained in the Vessel, and when it comes to be so, add thereunto more hot water, keeping the fire in that degree of heat, as may suffice to keep the water contained in the Copper, gently boiling.

Now when you have kept it thus boiling for some season, try the goodness of your water again, after the aforesaid manner; and if you shall find a Crystallization therein, and no Concretion, or heaping-together, leaving a gaping, or chap in the midst, the business is well done; but if it be otherwise (than thus well done) so that it be wholly shut in (or gathers a skin all over) at top, pour on hot water, until your Matters come to succeed after the manner aforesaid.

Then after all this, take of the best Wine Vinegar, about one pound thereof, and pour it into the said water, and you will presently see a blackish spume, or filth arise in plenty at the top thereof, and when you have left it so a while, it may be easily taken off, because of the thickness it contracts.

The boiling being yet a while longer continued, pour in the same quantity of Vinegar again, and diligently separate the Scum as afore: This pouring on of Vinegar, and separating of the Scum, may be repeated yet a third time, and oftner, whereby the purgatory water may be made altogether pure, and that there appears not any more spume.

When all this is done, cast in upon this water two or three Ounces of Burnt-Alum, most finely powdered, stir all well with a Spatula, whereby the Salt-petre may shoot into longer Crystals.

Then after this, pour out the purgatory water into the aforementioned deep Vessels, and cover them over with Linen Cloths, that the Liquor cool not. Let it stand thus one hour or two at most, and a yellow slime will settle to the bottom: Then let the water while it is yet warm flow out hence, into other Vessels made of wood, and especially of Elm, and which are large enough; or else, you may let it run into Copper Pans set deep in the Earth, for the better coolings sake, which cover over very neatly with Cloths, that so the Crystallization may begin from the bottom, and not at the upper part, as we see it wont to happen, where it is not kept by Coverings from the External cold: And we also observe therein too, that the Crystals shoot not into that length, as when the Crystallization begins from the bottom.

Let them stand thus for two or three days, until you see no more Crystals generated, which you may on this wise try.

Put some of the Lixivium in your (little) probatory Vessel, wherein, if you find that there are no more Crystals generated, you may take out the rest of the Lixivium: Then take out the Petre with an Iron Spatula (or Truel) and put it into a Vessel that is full of holes in the bottom, that so all the Lixivium may be the better separated therefrom. And you shall have your Salt-petre pure and white, and freed from its Salt.

Forasmuch as the Lixivium here separated hath as yet some saltness in it, it may be mixed with other strong Lixivium to be (agen) boil’d up, for the production of the Crude Salt-petre is usually holpen forward there-withal.

Some there are that for the better purifying the Petre, do put Calx vive in together (with it) whereby the water becomes most white like Milk, and the Salt-petre gets a greater fairness.

You must withal observe that during the time that the purifying water is contained in the Copper, your fire must be most gentle, least by overmuch boiling you get some damage, for a little fire is able easily to cause (a too vehement) ebullition, and when it has got strength (or the start of you) it is hardly allayed again. The scum which you take off from it you may pour upon ashes as if it were a Lixivium, that so nothing (from whence any profit can be hoped for) may be lost.

There is sometimes seen to stick to the bottom of the Copper (especially when it is used about many boilings) a certain stony and hard substance like Tartar, which unless it be taken away, your Copper will easily suffer damage under that same matter and be burnt.

The earth and ashes left, after the weak Lixivium (hath past through them) are to be laid up in some convenient place, and there kept for four years or more, that so they may be again apt to yield a-new more Lixivium by extraction; which, that it may be the better and easier done, there must be made in them (many weeks afore they are wrought upon) by digging some Pits or Gutters, that so they may be freed by the heat of the Sun from that moisture wherewith they as yet abound. Nor do the ancients so much wander from the Truth in that they suppose it much better and more profitable to keep all the earth under a roof or shed, and that it will be far sooner reduced unto a fitting goodness, than to lie open to the weather, for much of the Salt-petre is corrupted (or spoiled) with an abundance of moisture, especially with the Rain it self: For it needs only a little wetting whereby it may be generated, and extreamly shuns, or is injured by too much moisture.

Besides these ways, there are many that mix with this earth that is yet contained in the Tub the Saw-dust of Firr, or some other Wood (the height of) a Fingers length (on it): And they perswade that Salt-petre is also generated and multiplied from that fatness which is mixed with the Saw-dust, and that the earth prepared on this wise can be so changed in a years space (so it be kept in a dry place) that it may be again made use of as afore. Yea and they suppose too that they can do much here, if they pour upon such a barren (or lean) earth, thus lying in a dry place, the reliques or remains of the dyes, which the _Dyers_ are otherwise wont to throw away, and evident it is that they are aluminous, but yet not so frequently.

Besides such waters of the _Dyers_ they are wont also to mix soot with their earth, (yea and the ashes too of which Lawndresses do commonly make their Lee;) that so it may be made the more fruitful and may be the sooner brought to use.

This only is to be noted, that there are sometimes found earths that give a thick black Lee, which being used by it self is too fat, to which is to be added a leaner and dryer earth, that so the Salt-petre may be the better and more plentifully generated.

The way therefore how, and the instruments by which crude Salt-petre is purifyed, is shown by the 6 and 8 Figure (in _Lazarus Ercker’s_ Book I think he means.)

_The manner of purifying the gross and blackish =Salt= that comes
out of the =Salt petre=._

That black or rather ashy colour Salt, which is found in the Copper while the nitre is prepared by boiling, and likewise in the narrow Tub or Vessel, may be reduced into very good Salt, and very convenient for daily use, and no ways at all hurtful to Man, if it be but duly purified; which said purification is to be thus ordered.

The Copper being well cleaned fill it with most clear Well-water, put fire under it and make it boil, throw in the said Salt by times (not all at once) into the boiling water, that so it may be dissolved; which, that it may be the sooner and better done, stir it continually with a _Spatula_, when you think that it is all dissolved pour out the Lixivium into some Vessel or Tub, & you shall see the grosser part will settle to the bottom, and the Lixivium will clear up: When you perceive this, pour this clear Lixivium again into the cleansed Copper, and boil it so long till the Salt settles to the bottom, which take out of the said Copper with a perforated Ladle, and put it in a Basket that is placed over the Copper, that so all the superfluous Lee or moisture may again run down into the Copper, and yields (or leaves) the Salt perfect and dry.

Some there are who afore they use this Salt about domestick affairs, do decrepitate it first, and perswade themselves that it becomes thereby the more virtuous (or strong.)

What remains behind of the Lixivium in the Copper, you may boil it up like as you would any other Lixivium appointed to be Crystallized, then pour it out into the Vessels destinated to that purpose, and you shall see Salt-petre to be generated in them; for seeing the said Salt proceedeth out of the Salt-petre, this Lixivium cannot be wholly void of Salt-petre, and therefore may it be separated from that Salt by the aforesaid way, and be purified.

But you are to note here, that where there is too great a quantity of Salt-petre permixt with the said Salt, or that the Salt it self is too black and impure, that Salt cannot get its due lustre and whiteness by barely one such a purifying Operation, and therefore there is requisite a reiteration of this Operation, so that it be again dissolved in new water, and be purifyed, whereby it may become altogether white.

However, such a black and impure Salt, may be purified even by this way (following.) Pour the solution it self, while ’tis yet hot, (the water I mean in which the Salt is dissolved) upon the ashes which a Lixivium hath been already poured on before, and you shall see the Salt Lixivium to be wholly purified: But yet all the Salt which is extracted thence, is not sufficiently white, but that which is gathered last of all is yellowish, and therefore must be yet once again purified. Note also here, that when such a Lixivium of Salt is poured on the ashes, they must be well edulcorated (after the operation is finished) least the Salt sticking in the Reedy or Bull-rush-bottom should give an unfitting saltness to the Lixivium that is next poured thereupon.

And thus have you the common method of boiling and preparing Salt-petre, in which you meet with what may be well disallowed or rejected, _viz._ it is extreamly tedious, nor is it at all gainful, for out of a centenary of Lixivium, we have no more than three or four pound of Petre; to get which too, all the rest of the water must be done off by evaporation, which is a long time doing, and requires no small costs. Yet I will shew in what follows, by what means this inconvenience may be prevented, which I have proved by mine own experience.

_The way of augmenting the Crude Lixivium afore its boiling._

The Salt-petre boilers have hitherto variously sought after the way of augmenting (or fortifying) the Lixivium of Salt-petre, that is, of causing a more plentiful provenue of Salt-petre, in the Water remaining of the extraction of Salt-petre, but in vain, because they were ignorant of the lesser proof which all things here are tried by. Its augmentation is done on this wise.

Take of a Lixivium, a Centenary of which contains _iiij._ ℔. of Nitre, pour so much of it as a Tub or Vessel will hold, upon new earth, let it stand for twelve hours; then draw off the Lixivium, and as much as you find wanting of what you poured on (which may easily be known by the emptiness of the measure which it was in, afore you poured it on, and in which it is now gathered or received again) pour so much simple water on the Earth, which draw off in like manner, and mix it with the Lixivium, and you will then have the same quantity that you had in your Vessel afore. This done try the Lixivium by the lesser experiment or proof and you will find it to contain _vj._ ℔. of Nitre. Pour this Lixivium that contains in it _vj._ ℔. of Nitre upon other new earth, and proceed on the manner aforesaid, and you shall have your Lixivium to contain _ix._ ℔. of Nitre. You may pour this a third time upon other new earth & proceed on with it after the aforesaid manner, and you shall yet have more Nitre out of a Centenary of Lixivium. But you must be always wary in this Operation, that you draw off, neither more nor less Lixivium from the earth than you had before in the Vessel. These things it pleased me to add, concerning the second pouring on of water, meerly for the experiments or proofs sake, whereby we may be made certain of the augmentation thereof (forasmuch as the Lixivium doth by this means hold in it more Nitre) and that we may be forced to acknowledge its augmentation even in that way. Then after this is done, you may use the weaker Lixivium instead of water, to fill up the first measure, and so the Lixivium will be the easier, and more augmented; and we may in a short time have sufficient quantity hereof for to boil. And although this augmentation of the Lixivium requires a great deal of labour, yet are all the (pains, &c.) recompensed, because we hereby get in one Weeks space, and with less expence of Wood, far more Nitre than by the other common ways: But yet there are requisite more Vessels for this kind of working, wherein the separated Lixivium may be kept.

I will also give the Reader a manuduction here, by what way the boiling of the Lixivium is to be ordered, or contrived: First of all, this is well to be regarded, that forasmuch as a great boiling requires a great quantity of earth, and yet there does not at all times, earth of a like goodness offer it self (especially seeing a Man cannot make proof of it all) upon which the costs and labours (necessary about it) may be well (or at the best hand) bestowed: It seems wholly expedient, not to make such a great Coction (or boiling-trade) but to do it with only three or four Tubs, that so we may choose only the best convenient earth, which we may dig in the Cities (or Towns) out of Houses of long standing, and out of Stables, but yet not too deep: Such a Lixivium as contains in an hundred weight of it eight pounds of Nitre, may be increased to eighteen or twenty pounds, if we proceed according to the aforesaid method. And therefore such Nitre boilers as inhabit those regions where there is scarcity of Wood may give hereunto good heed.

Now the Lixivium augmented on this wise, doth not attract all the nitre out of the earth it self, but there doth yet some always remain behind: And therefore you need not presently throw it away, but pour thereupon some simple Waters, which after it hath stood thereon for some hours, draw off again, and you shall have a weak Lixivium, which you may try by the proof, and proceed on therewith in the method of augmenting it, and so you will have a continual labour.

This likewise is to be observed in an especial manner, let the Work-house in which this boiling up of your Salt-petre is done, be very low, and covered with thatch, that so the heat may be the better kept about the Tubs, and this Operation may be done as well in the Winter as in the Summer, and that the weak Lixivium may not at all congeal.

And now, even as Salt-petre is made by boiling, out of the Lixivium which is made of Earth, even so is it of that Lixivium which is gotten out of Stones or the Lime (and Dung) Arches (afore-spoken of;) only there is this difference, That this last way of my contrivance (with stones &c.) is easier, and yields more Nitre. Such as are pleased with this kind of work may set about it, nor will they bestow their Labours in vain; there may be abundance of things, and those wonderful ones too, effected with Salt-petre, as I have abundantly demonstrated in my foregoing Writings, and shall in my following ones too, more clearly demonstrate if God vouchsafe strength and abilities.

But before I come to the practice it self, and to describe the benefits of Salt-petre in specie (or in particular) it is wholly necessary to shew how wonderful, yea how incomparable a subject, that Salt-petre is. And this thing I have already handled at large in the _Second Part of the Philosophical Furnaces_, in the _Second Part of the Pharmacopœia Spagyrica_, but especially in my _Miraculum Mundi_, and in the _Explication_, and _Continuation_, and _Defence_ of the same.

* * * * *

_Here the Author runs out into a large digression in his own vindication, upon the occasion of certain Letters sent him by one =I. H. S.= who Stiled himself the Son of =Sendivogius=; in which Letters he highly extols the Hermetick learning of the Author, but blames him for Writing so plainly of great secrets, and exhorts him to be more sparing and obscure for the future. Withal offering his service (and begging the Authors leave) to defend his Person and Writings against =Farnner= and others. The Author not taking his advice nor yet accepting of his service (suspecting him to be a self designer) this =I. H. S.= afterwards published a Book entituled =Lucerna Salis Philosophorum=. In which he offers to teach the making of the =Philosophers-stone= at a price or reward; and reproacheth =Glauber= whom he before had so highly magnified in several Letters, advising People to avoid his writings as Sophistical. In this Treatise he mentions a Prediction or, Prophecy of three Monarchs that were to appear in the World: The first of =Paracelsus=, concerning =Elias= the Artist. Secondly, That of =Cosmopolita= of the coming of the =Northern Monarch=. Thirdly, That of =Jacob Behmen=, That a Lily shall bring forth Flowers from the North. He intimates that himself is the =Elias= of Arts. Secondly, That some =Northern Monarch= shall do mighty things in the World: And Thirdly, that the Writings of =Jacob Behmen= should be again Printed a new. After the Author hath shewed the ill dealing of this =I. H. S.= with him, and vindicated himself, then he proceeds briefly to Comment upon these three Predictions or Prophecies._

* * * * *

By what hath been said, may the Candid and well-minded Reader judge what judgment is to be had of this Monarch of Arts I. H. S. Every one that reads them will find whether or no such a Monarchy is to be expected from such a ones Writings. But now that I my self may likewise here produce my opinion, concerning _Paracelsus_ his meaning where he writeth, _I say that the most eminent Secrets will not be known afore =Elias= the Artist shall come and teach them_: (But I pray) what hath the holy Man _Elias_ to do with Arts? verily no thing at all. _Paracelsus_ minded or pointed at some other thing, he well knew, that no body comes unto such knowledge, unless by Revelation from God, by godly Prayers, and by searching: This is the true _Elias_ which _Paracelsus_ speaketh of, if (_viz._) the word _Elias_ be read backwards, and E changed into A: For then ’tis the same with _Salia_ (that is, Salts) such as these (_viz._ salts) are known unto, to them is _Elias_ a master or teacher. And where the said _Paracelsus_ speaketh of Salts he adds _Alchimy finds it (to be) in Nitre_: Hereby shewing and pointing at _Salia_, Salts, which word being read backward is _Elias_? And this is my opinion as touching the coming of _Elias_ the Artist, and I do yet (again) say, that to him to whom Salts are known, hath _Elias_ appeared. And let this be sufficient to have spoken of the first Monarchy of I. H. S. and what is to be judged thereof.

_Now follows the Second =Monarchy=._

As for the second Monarchy, he alledgeth the Prophecy of _Paracelsus_, which runs thus: _A Lion shall come from the North, and become the Monarch of the World_: Which Prediction is not at all to be understood according to the Letter. What has _Paracelsus_ to do with the Northern Lion? What business has he with the Monarch of the World. Some there are that endeavour to attribute that Prophecy to one or other of the Northern Kings, but yet that was not in the least _Paracelsus_’s meaning, he drove at a far other-guess business, and by that Lion he meant Salt-nitre, which is wont to be brought unto us by the Northern Winds, Rain and Snow, and that several times yearly as is well known unto all; hereupon many amongst the Philosophers, and some of them the latter Philosophers, have filled great Vessels with the Rain and Snow that comes out of the North, and aimed at the preparation of a Tincture thereout of, but they found nothing else but Salt-petre, which to get, I have shown a much shorter way.

_Paracelsus_, _Basilius_, and others have Written many things of the green and red Lion, all which are to be understood of Salt-nitre, which may most easily be transmuted into the green or red Lion, concerning which thing I my self have made mention in many places.
