The new furnace at Limerock will make from three to four hun- 

 dred tons. Formerly, a great proportion of this iron was sold in 

 pigs ; but for the last few years it has principally been converted in- 

 to bar iron at the furnaces where produced, or at Winsted, in the 

 forges of S. Rockwell, James Boyd &l Son, and Reuben Cook. At 

 the works, it formerly commanded thirty -five or forty dollars the 

 ton; but at present it sells at thirty or thirty-two. The Salis- 

 bury Iron Company have two forges at Riga, containing seven fires, 

 an anchor and screw shop with two fires, a lathe for turning iron, and 

 a trip-hammer shop. They have also at Limerock a forge with six 

 fires. This company makes about four hundred and fifty tons of 

 wrought iron annually, which is made into the following articles ; 

 viz. bar iron for musket and rifle barrels, and for common uses for 

 the country blacksmiths ; axletrees, crow-bars and tires for wheels ; 

 irons for grist and saw mills ; anchors, large and small ; shafts for 

 steam engines, and manufactories of all kinds ; large screws for 

 clothiers, paper-makers, and for pressing bales of cotton and hay. 

 Canfield, Sterling &. Co. have one forge with six fires ; and another 

 with two, and an anchor shop. They make from two hundred and 

 fifty to three hundred tons of tough iron annually ; and furnish most 

 of the articles mentioned above, except screws. 



The best Salisbury iron has obtained a decided preference over 

 all odier iron, either foreign or domestic, for the construction of 

 musket and rifle barrels ; and is extensively employed for these pur- 

 poses at all our principal gun-factories, both public and private. The 

 annual consumption at die following manufactories is as follows.
