plumbago, or of any fubftance containing the coally or car- 

 bonaceous principle ; but, in general, charcoal, pit-coal, or pit- 

 coai cokes, cfpocially if prepared in the manner herein after 

 defcribed, will be found to anfwer befh For this procefs not 

 only bar iron may be employed, but alfo what is commonly 

 called fcraps, or walk iron; but, when the latter is ufcd, a 

 little more carbonaceous matter mud be added to the mixture, 

 to revive the ruit, or oxyd of iron, adhering to the fcraps. 

 The mixture in the crucible or crucibles mull then be put 

 into a furnace capable of giving a fufficiently intenfe degree 

 ot heat to run down or fufe the mixture, wliich mull then be 

 poured out into bar, ingot, or other moulds, according as the 

 manufacturer intends to produce bars or ingots, or various 

 articles or utenfils that are, or may be, made of caft fteel ; 

 for the whole iron, by fulion with the charcoal or other fub- 

 llances or things containing carbonaceous matter, will be 

 found to have palfed into the date of cad deel. If cad into 

 bars or ingots, and a proper quantity of charcoal, or other 

 fubdances or things containing carbonaceous matter, has 

 been employed, fuch bars or ingots will be found in a date 

 ready to take the hammer, and to be drawn or rolled into 

 other diapes, according tojhe intention of the manufa6lurer. 

 In fome cafes, efpecially where a heavy charge is to be run 

 down, the crucibles mud be previoufly properly difpofed in 

 the furnace, and the mixturo introduced into them' after- 

 wards. 



**^ By the procefs before defcribed, and which may be 

 varied with circumdances by any prudent operator, cad deel 

 may be made in a fe\v hours, which, by the procefs or pro- 

 cedes hitherto difcovered, has ufually required many days, 

 and fometimes weeks; for call deel, by the common method 

 of manufa<^lure, has been hitherto made from bar deel, 

 which had previoully required, for its own converfioii into 

 that date, from the date of bar-iron, or of fcrap-iron, a 

 tedious cementation with charcoal, in a fdrnace coridru6led 

 for the purpofe, and ufually known among manufa6lurers 

 bv the name of a convertinor furnace.

 duly faving in point of time and cxpcnfe, gained by my pro-
