ve, where I was sure, there wanted not Iron-Ore.)
And what other wayes may be used to direct Miners without the help of a
Load-stone?
43. How the Miners deal with the Rocks and Sparrs, they often meet with,
before they come at the Ore? Whether they use Fire to soften, calcine, or
crack them? How they employ it, and with what measure of success?
44. What wayes and cautions they use, to free the Mine and secure the
Work-men from the inconveniencies and danger accruing from the use of much
fire in it?
45. What Instruments they use to break the Rock &c? And how those
Instruments are conducive; and how long they last?
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 acquainta
