46. How the Mine-men work; whether naked or cloathed? And what Lights they use to work by; what materials they are made of, what measure of light they give; how long they last; and by what wayes they are kept burning in that thick and foggy air? 47. How Veins are follow'd, lost, and recover'd? And how several Miners work on the same Vein? And what is the best way of getting all the Ore in a Vein, and most conveniently? 48. How they convey out their Ore, and other things, that are to be carried out of the Mine? Whether they do it in Baskets drawn up by Ropes, or upon Mens backs; and if this last-named way; what kind of Vessels they use for matter, shape, and capacity? And whether the Work-men deliver them one to another; or the same Work-men carry them all the way? And whether the Diggers descend and ascend by Ladders of Wood, or of Ropes, &c. _About the Fifth Title._ 49. Whether the Ore runs in a Vein; or lie dispers'd in scatter'd pieces; or be divided partly into a Vein, and partly into loose masses; or like a Wall between two Rocks, as it were in a Cleft; or be interspers'd in the firm Rock, like speckled Marble? Or be found in _Grains_ like _Sand_ or _Gravel_; as store {337} of excellent _Tin_ is said to be found in some parts of _Cornwall_ at the Sides and in the Channels of running Waters, which they call ...; or whether the Ore be of a softer consistence, like _Earth_ or _Lome_, as there is Lead-ore in _Ireland_ holding store of Silver, and Iron-ore in the North parts of _Scotland_ and elsewhere? And what is observable in it as to Weight, Colour, Mixture, &c? 50. Whether any part of the Metal be found in the Mine perfect and complete? (As I have had presented me good valuable _Copper_, and pieces of perfect _Lead_, that were taken up, the one at _Jamaica_, and the other by an acquaintance of mine, that took them out of the ground himself in _New England_.) 51. Whether the Mine affords any parcels of Metal, that seem to grow like _Plants_ (as I have sometimes seen Silver growing, as it seemed, out of Stone, or _Sparre_ almost like blades of Grass; as also great Grains of a Metal, which appear'd to me, and which those, that tryed some of it, affirmed to be Gold, abounding in a stony lump, that seem'd to consist chiefly of a peculiar kind of _Sparre_.) 52. Whether the Vein lie near, or much beneath the surface of the Earth, and at what depth? 53. Whether the Vein have or have not any particular Concomitants, or Coats (if I may so call them;) and, if any, what they are, and in what order they lie? (As the Veins of _Lead-ore_, with us, have frequently annnext to them a Substance call'd _Sparre_, and next to that another, call'd _Caulk_.) 54. Whether (besides these Coats) the Vein have belonging to it any other _Heterogeneous_ substance? (As in _Tin-mines_ we often find that yellow substance, which they call _Mundick_.)
