and examine the goodnefs of the Ore In imall quantities ? 
71. Whether, when they work Ingres/, they ufe to melt 
the Ore with any Flux or Additaments , or only by the force of 
the Fire, or in any way between both? ( As throwing in of 
Charcoals when they melt Iron- Hone does not only ferve to feed 
the Fire * but perhaps by the Alchalj of its Afhes to promote 
tiie fufior : fb Lime-Hone, &c .) 
72. What kind of Furnaces theyufe, to melt the Ore in? 
Whether they be all of one fort and bignefs, or of differing ? 
73. What are, the Situation, Materials , Dimenfions , Shape, 
Bignefs and in ihort what is the whole ftru&ure and Contri- 
vance of the Furnace ? If there be any thing peculiar and remar- 
kable? What Tools are ufed in Smelting, their Figures, ufe, 
And the whole manner of working ? 
74. What kinds of Fewel,and what quantities of it, are wont , 
to be employed in the Furnace , within the compafs of a day, 
or week ? How much is put in at a time ? How often it is re- 
newed ? And how much Ore in a determinate time , as a week 
or a day , is wont to be reduced to Metal ? 
75. In cafe an Additament bo employed , what that is;, and 
In what proportion it is added ? VVhether it be mingled with 
the Ore, before that be put into the Fire, or caft in after- 
wards 5 and, if fo, at what time, &c ? 
78. Whether the Ore be melted by a Wind, excited by the 
Fire it felf, as in Wind-ovens? Ore by the courfe of Wa- 
ters ? Or acuated by the blaft of Bellows , and, if fo , whether 
thefe Bellows be mov’d by a Wheel, turn’d by VVater run- 
ning under it , or falling on it ? And what are, the Dimenfions, 
Situation, &c. of the Bellows ? 
79. What contrivance they have to let or take out the 
Metal, that is in fufion } and caft it into Barrs, Sows, Pigs. &c .<? 
80. What Clay, Sand , or Mould they let it run or pour It 
through ? And after what manner they refrigerate it ? 
81. Whether or no they do , either to facilitate the fufion, 
or to obtain the more or better Metal, mingle differing forts 
or degrees of Ore of the fame metal ? ( As in feme places TIs 
tifual, to mingle poor and rich Ore 5 and at Mendip they mix two 
or more of thofe differing kinds of Lead-ore that they call Frim - 
ore^ Steel-ore^ Totem-ore^ See.) f 82. Whe-
