On the Manufacture of Bar Iron in India, 35 



with, yet the operation not being continuous, but suspend- 

 ed, when the bloom is ready for removal, and the furnace 

 allowed to cool, much heat and fuel are wasted which might 

 manifestly be saved by maintaining the furnace always at 

 a proper heat. 



4. This objection may be remedied in what may be de- 

 fined as M reverberatory bloomeries," in which the bloom is 

 reduced and balled contiguous to the focus of heat, but in 

 such a situation that its removal does not require the charge 

 of ore put into the furnace to be suspended, nor the blast to 

 be stopped. Furnaces of this kind were tried by Mashet, but 

 did not succeed in consequence of the ore not being intro- 

 duced in a proper manner. Even on the small scale at my 

 disposal, I have succeeded in making " reverberatory 

 bloomeries" answer perfectly well ; but my mode of manage- 

 ment though much the same in general principle, differs 

 considerably from that employed by Mr. Clay in Scotland. 



5. " The New York newspapers announce that Mr. Simeon 

 " Broadmeadow, of New York, has invented a method, by 

 " means of which the iron ore is by only one process con- 

 " verted into wrought iron, without being first made into 

 M pig-iron, and at a less expense than the pig-iron can be 

 " made. The iron ore is placed upon the floor of a rever- 

 " beratory furnace, the flame of the fire passing over it, when 

 V a chemical compound is used to unite the elements of the 

 " iron by separating the slag entirely from it. By this first 

 " and only operation, the wrought iron comes out as perfect 

 M in every respect as that by the double operation of pud- 

 " dling and piling pig-iron; and for the purposes of manufac- 

 " turing steel, even surpasses it. By this process wrought 

 " iron of the best quality can be produced at a cost not ex- 

 u ceeding 25| dollars per ton. It is also calculated that the 

 " rough blooms, if the furnace is built near the mines of 

 u coal and ore, can be made with a good profit for only 14 

 " dollars per ton. The inventor states, that with a capital
