Being nearly one-fifth in amount as much as is wanted for railroad 

 bars, estimated for the year 1847 at 100,000 tons. If we load upon 

 these 18,000 tons $50 unnecessarily, or say $900,000 in profits, we 

 may and shall have to compete with the English maker for a part of 

 it; but if we load upon it in the form of profits but $300,000, (or. 

 about $25 per ton,) we secure the making of the whole amount to 

 ourselves. 



We will now see how these defects apply to the making of rail* 

 road bars at the present time. Take a mill, in the first place, having 

 no connection with ore beds or blast furnaces, but which buys its pig 

 metal in market as it best can, the price of which, at this time is 

 about $25 per ton; to which, add 25 per cent for waste ($6.25) say
