musket and rifle-barrels, and for common uses for the blacksmith ; 
anchors, axle-trees, iron-bars and tires for wheels, irons for grist and 
saw-mills, shafts for steam-engines and manufactures of all kinds ; 
large screws for clothiers, paper-makers, and for pressing bales of 
cotton and hay. The best Salisbury iron has obtained a decided 
preference over all other iron, either foreign or domestic, for the con- 
struction of musket and rifle-barrels. 
‘The Kent bed was formerly considered as a very important de- 
posit of ore. It supplied several extensive forge establishments for 
a great number of years with ore of an excellent quality ; but partly 
in consequence of the unskillful and improvident manner in which 
the original workings were conducted, and partly from the limited 
extent and peculiar situation of the bed, it has now sunk into almost. 
total neglect. It is situated on the western declivity of a low moun- 
tain, nearits base. In length the mountain is about three miles, and 
in height two hundred feet. Its length corresponds with the edges 
of stratification in the vicinity, which do not differ essentially from 
north by east. 
‘¢ At present the workmen are directing their attention to a more 
recent opening, situated seventy or eighty rods north of the old 
mine, on the same slope and at the same elevation above the valley. 
It has been worked more or less for a period of thirty years. Until 
lately, the ore was obtained exclusively by burrows; but they have 
now formed a deep drain, open to the air as at the old bed, and from 
the sides of this drain they carry in burrows, where the workmen 
operate to advantage during the winter.
