nce 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_.)

55. What are the principal Qualities of these Extraneous substances? (As
that _Sparre _ is white, but transparent, almost like course Crystall,
heavy, britle, easily divisible into flakes, &c. _Caulk_ is of a different
texture, white, opacous, and like a Stone, but much more ponderous.
_Mundick_ I have had of a fine golden colour; but, though it be affirm'd to
hold no Metal; yet I found it in weight, and otherwise, to differ from
_Marchasites_; and the Mine-men think it of a poisonous nature.) {338}

56. Whether the Vein be inclosed every way in its Coats; or whether it only
lye between them?

57. Whether the Vein be every way of an uniform breadth, and thickness;
and, if it be, what these Dimensions are; and if not, in what places it
varies, and in what measures? (The like Questions are to be made concerning
the _sparre_, _Caulk_, and other Teguments or mixtures of the Ore?)

58. Whether the Vein be un-interrupted, or in some places broken off; and
whether it be abruptly, or not; and whether it be by Vales, Brooks,
Gullets, &c?

59. How wide the Interruptions are? what Signs, whereby to find the Vein
again? whether the ulteriour part or division of the Vein be of the same
Nature, and hold on in the same Course, as to its tendency upwards or
downwards, or Horizontally, Norward, Southward, &c. with the Vein, from
which it is cut off?

60. Whether, in case the last end of the
