Their ordinarie tooles, are a Pick-axe of yron, about sixteene inches long, sharpned at the one end to pecke, and flat-headed at the other, to driue certaine little yron Wedges, wherewith they cleaue the Rockes. They haue also a broad Shouell, the vtter part of yron, the middle of Timber, into which the staffe is slopewise fastned.
Their maner of working in the Loadmines, is to follow the Load as it lieth, either sidelong, or downe-right: both waies the deeper they sincke, the greater they find the Load. When they light vpon a smal veine, or chance to leefe the Load which they wrought, by means of certaine firings that may hap to crosse it, they begin at another place neere-hand, and so draw by gesse to the maine Load againe. If the Load lie right downe, they follow it sometimes to the depth of fortie or fiftie fathome. These Loadworkes, Diod.Sic.l.5.cap.8. seemeth to point at, where hee saith, that the Inhabitants of Veleriumm Promontorie, digge vp Tin out of rockie ground. From some of their bottomes you shal at noone dayes discrie the Starres: the workmen are let down and taken vp in a Stirrup, by two men who wind the rope.
If the Load lie slope-wise, the Tynners digge a conuenient depth, and then passe forward vnder ground, so farre as the ayre will yeeld them breathing, which, as it beginneth to faile, they sinke a Shaft downe thither from the top, to admit a renewing vent, which notwithstanding, their worke is most by Candle-light. In these passages, they meete sometimes with verie loose earth, sometimes with exceeding hard Rockes, and sometimes with great streames of water.
The loose Earth is propped by frames of Timber-worke, as they go, and yet now and then falling downe, either presseth the poore workmen to death, or stoppeth them from returning. To part the Rockes, they haue the foremencioned Axes, and Wedges, with which, mostly, they make speedie way, and yet (not seldome) are so tied by the teeth, as a good workman shall hardly be able to hew three foote, in the space of so many weekes. While they thus play the Moldwarps, vnsauorie Damps doe here and there distemper their heads, though not with so much daunger in the consequence, as annoyance for the present.
For conueying away the water, they pray in aide of sundry deuices, as Addits, Pumps &. Wheeles, driuen by a streame, and interchangeably filling, and emptying two Buckets, with many such like: all which notwithstanding, the Springs so incroche vpon these inuentions, as in sundrie places they are driuen to keepe men, and some-where horses also at worke both day & night, without ceasing, and in some all this will not serue the turne. For supplying such hard seruices, they haue alwaies fresh men at hand.
[12] They cal it the bringing of an Addit, or Audit, when they begin to trench without, and carrie the same thorow the ground to the Tynworke, somewhat deeper then the water doth lie, thereby to giue it passage away.
This Addit, they either fetch athwart the whole Load, or right from the braunch where they worke, as the next valley ministreth fittest opportunitie, for soonest cutting into the Hil: and therfore a Gentleman of good knowledges, deduceth this name of Addit, Ab aditu ad aquas. Surely the practice is cunning in deuice, costly in charge, and long in effecting: and yet, when all is done, many times the Load falleth away, and they may sing with Augustus bird, Opera & impensa periit. If you did see how aptly they cast the ground, for conueying the water, by compassings and turnings, to shunne such hils & vallies as let them, by their two much height or lownesse, you would wonder how so great skill could couch in so base a Cabbin, as their (otherwise) thicke clouded braines.
As much almost dooth it exceede credite, that the Tynne, for and in so small quantitie, digged vp with so great toyle, and passing afterwards thorow the managing of so many hands, ere it come to sale, should be any way able to acquite the cost: for being once brought aboue ground in the stone, it is first broken in peeces with hammers; and then carryed, either in waynes, or on horses backs, to a stamping mill, where three, and in some places sixe great logges of timber, bound at the ends with yron, and lifted vp and downe by a wheele, driuen with the water, doe breake it smaller. If the stones be ouer-moyst, they are dried by the fire in an yron cradle or grate.
From the stamping mill, it passeth to the crazing mil, which betweene two grinding stones, turned also with a water-wheele, bruseth the same to a fine sand: howbeit, of late times they mostly vse wet stampers, & so haue no need of the crazing mils, for their best stuffe, but only for the crust of their tayles.
The streame, after it hath forsaken the mill, is made to fall by certayne degrees one somwhat distant from another; vpon each of which, at euery discent lyeth a greene turfe, three or foure foote square, and one foote thick. On this the Tinner layeth a certayne portion of the sandie Tinne, and with his shouell softly tosseth the same to and fro, that through this stirring, the water which runneth ouer it, may wash away the light earth from the Tinne, which of a heauier substance lyeth fast on the turfe. Hauing so cleansed one portion, he setteth the same aside, and beginneth with another, vntil his labour take end with his taske. The best of those turfes (for all sorts serue not) are fetched about two miles to the Eastwards of S. Michaels Mount, where at a low water they cast aside the sand, and dig them vp: they are full of rootes of trees, and on some of them nuts haue beene found, which confirmeth my former assertion of the seas intrusion. After it is thus washed, they put the remnant into a wooden dish, broad, flat, and round, being about two foote ouer, and hauing two handles fastened at the sides, by which they softly shogge the same to and fro in the water betweene their legges, as they sit ouer it, vntill whatsoeuer of the earthie substance that was yet left, be flitted away. Some of later time, with a sleighter inuention, and lighter labour, doe cause certaine boyes to stir it vp and downe with their [13] feete, which worketh the same effect: the residue after this often cleansing, they call blacke Tynne, which is proportionably diuided to euerie of the aduenturers, when the Lords part hath beene first deducted vpon the whole.
Then doth each man carrie his portion to the blowing house, where the same is melted with Char-coale fire, blowne by a great paire of Bellowes, mooved with a water-wheele, and so cast into peeces of a long and thicke squarenesse, from three hundred to foure hundred pound waight, at which time the owners marke is set thereupon. The last remooue, is to the place of Coynage, which I shall touch hereafter. I haue alreadie told you, how great charge the Tynner vndergoeth, before he can bring his Owre to this last mill: whereto if you adde his care and cost, in buying the wood for this seruice, in felling, framing, and piling it to bee burned, in fetching the same, when it is coaled through such farre, foule, and cumbersome wayes, to the blowing house, together with the blowers two or three Moneths extreame and increasing labour, sweltring heate, danger of skalding their bodies, burning the houses, casting away the worke, and lastly their ugly countenances, tanned with smoake and besmeared with sweate: all these things (I say) being duly considered, I know not whether you would more maruaile, either whence a sufficient gaine should arise to counteruaile so manifold expences, or that any gaine could traine men to vndertake such paines and perill. But there let vs leaue them, since their owne will doth bring them thither. During the Tinnes thus melting in the blowing house, diuers light sparkles thereof are by the forcible wind, which the bellows sendeth forth, driuen vp to the thatched roofe. For which cause the owners doe once in seuen or eight yeeres, burne those houses, and find so much of this light Tynne in the ashes, as payeth for the new building, with a gainefull ouerplus. A strange practise (certes) for thrifts sake, to set our house on fire. Others doe frame the Tunnels of the Chimnies verie large and slope, therein to harbour these sparkles, and so saue the burning. This casualtie may bee worth the owner some ten pound by the yeere, or better, if his Mil haue store of sutors. But sithence I gathered stickes to the building of this poore nest, Sir Francis Godolphin, (whose kind helpe hath much aduanced this my playing labour) entertained a Duch mynerall man, and taking light from his experience, but building thereon farre more profitable conclusions of his owne inuention, hath practised a more sauing way in these matters, and besides, made Tynne with good profit, of that refuse which the Tynners reiected as nothing worth.
We will now proceede, to take a view of the orders and customes most generally vsed among the Tynners.
Their workes, both Streame and Load, lie either in seuerall, or in wastrell, that is, in enclosed grounds, or in commons. In Seuerall, no man can search for Tynne, without leaue first obtained from the Lord of the soile; who, when any Myne is found, may worke it wholly himselfe, or associate partners, or set it out at a farme certaine, or leaue it vn wrought at his pleasure. In Wastrell, it is lawfull for any man
