Hundred weight of Metal at one melting, which is the 
Produd of about three times fo much Oar.

SIR, 
I Send now at laft the promifed Parcels of Iron Oar, 
one fort of it feems to be good Hamatites. It feems 
I either did not rightly apprehend, or was not cleariy 
enough informed by the Perfon from whom 1 had the 
Account I Cent you, of the Furnace in which they melt 
down their Oar. 
It is very much like a common Black-fmiths , viz. A 
plain open Hearth or bottom without any enclofing 
Walls, only where the nofe of the Bellows come in 
through a Wall there is a hollow place (which they call 
the Furnace) made of Iron Plates, as is alfo that part 
of the Hearth next adjoining. This hollow place they 
fill and up-heap with Charcoal, and lay the Oar (bro- 
ken fmall) all round about the Charcoal upon, the flat 
Hearth, to bake it as it were, or neal and thruft it in by 
little and little into the Hollow, where it is melted Iby 
the Blaft. The glaffie Scoria run very thin, but the 
Metal is never in a perfect Fufion, but fettles as it were 
in a Clod, that they take it out with Tongs, and turn it 
under great Hammers, which at the fame time beat off 
(efpecially at firfl: taking out of the Furnace) a deal of 
comtex Scoria, and form it after feveral Heats into Bars. 
They ufe no Lime-ftone or other thing to promote the 
Flux, for that I enquired particularly. As to other 
matters my former Relation is exa£t enough.
