not the time, at present, To give the necessary tl
tn which to calculate the cost per ton OF rerp,l
ing old rails, or Of manufacturing them from the
pig. WILL however in my next wish to call
attention in this to two important items in ro!linS
mill operations First, the of magnetic iron
ore in the hearths of pudding fires: and second,
the fact that iron may be run from the blast fur
into the pudding furnace, and thus he CON
ycrted into rails, without reheating-or at least
into pudlied iron-before it gets cold.
short distance above Lynchburg we find sew
eral veins deposits of magnetic ore, which nlry
be delivered at iron works in that city for - per
ton. Magnetic is used to line the hearths Of
the pudding furnaces, to preserve the hearths and
to save the usual waste of iron. In open tu yes,
used in the mountains, the loss OF iron is
ly onethrd---t that is, three tons of pig iron will
only produce two TONS Of bar iron. In rolling
mills, where magnetic iron cannot be had at rea-
sonable pricessa from So to $40 per ton--sonp
stone and other fre-p proof material is used; this,
however, only saves the hearths, and not the iron,
t.oush it involves a cost. nevertheless. The waste
OF IRON in such mills is from one to two hundred
pounds. and more to every ton OF iron used OF
one-tenth of the entire amount; which, supposins
the iron to cost S25 per ton, amounts to $3.50.
iuls, on 10000 tons of iron, would nett sd 900
per annum. But, we could not save all this large
sum. even at Lynchburg as We must subtract
than the soap-stone or any other substitute.
1t We use from one to two hundred pounds #
magnetic ore, yielding from 70 to IS per cent. OF
pon to every ton OF pig ur cd rails re-meted. TIE
Per centage of iron in the magnetic ore is added
10 the puddled iron. and thus makes up for the
loss. In many rolling mills. with which we are
acquainted. the yield of pudiled iron is greater
than the amount of pig IRON used. The l'ss, II.

magnetic ore supplied. Ii magnetic ore can ie
delivered fer So per ton. the cost Of enc bundled
