 them. They conv out their Materials in Elme-Buckets drawn by Ropes. The Buckets hold about a Gallon. Their Ladders are of Ropes.

To the 49, 50, 51. The Ore runs sometimes in a Vein, sometimes dispers'd in Banks. It lies many times between Rocks: some of it is hard, some milder, They never find any perfect, but it muff be refined. Many times they have branched Ore in the Sparr.

To the 53--till 60. There is Sparr and Caulk about the Ore; and another substance, which they call the Crootes, which is a mealy white stone, marred with Ore, and soft. The Sparr is white, transparent, and britle like Glass. The Caulk, white and heavy, heavier than any stone. The Vein lies between the Coats, and is of different breadths. It breakes of sometimes abruptly in an Earth, they call a Deading Bed, and after a fathom or two may come again, keeping the same point. It terminates sometimes in a dead Earth Clayie, without Croot or Sparr; sometimes in a Rock called a Fore-stone.

To the 62 till 65. There is much difference in the goodness of the Ore. The cleerest and heaviest, best. 36 hundred of Ore may yield a Tun of Lead. Some small eyes of other mixtures, Brass, &c.

To the 66. They beat the Ore with an Iron flat piece; cleanse it in Water from the dirt; lift it through a Wire-sive. The Ore tends to the bottom, and the Refuse lies at top. And these are the Preparations, they make use of, before 'tis fit for fusion. Then they have a Hearth about 5 foot high, set upon Timber, to be turn'd as a Wind-mill, to avoid the inconvenience of smoak upon a shifting VVind. The Hearth contains half a bushel of Ore and Coal, with bellowes on the top. The Charcoale is put upon the Hearth, where the Ore is; laying dry Gads upon the top, which they call their VVhite coales. There is a sink upon the side of the Hearth, into which the Lead runs, that holds about an hundred and an half. Then it is cast into Sand, and runs into those Sowes (as they call them) which they sell. They have a barr, to stir the Fire; a shovel, to throw it up; and a Ladle heated red-hot, to cast out the Metal.
