THE NEW PROCESS OF MAKING WROUGHT


IRON.
An interesting letter written by Mr. "aro'
of Newark, N. j., to the late from Conven.
ton appears in the Pi,tsburg Commercial
Journal of the Sd instant. The Journal re-
cards the invention referred TO in the letter.
as tsdes,ined 10 work a total revolution IN Inc
business of making iron;" adding that, IL oar
iron made by this process can besold in New
York at s25 per ton, '',he iron interest oil
Pennsylyania may need no other protection
for the present, against the influx OF British
iron, than the operation Of the patent for the
new invention."'
oThe Journal also mentions that kentuc.
XIV manufacturer, on reading Mr.. Ward's
letter and examining the specimens, proceed
ded TO New Jersey to avail himself OF the
new process, and apply it 10 his Iron Works
"The specimens Of the iron sent to the Con-
vention,n il is added, "consist Of two sizes OF
hoop, 1 and 1. inch; quarter bar 9-lo OF
an inch d. rod inch thick, and horse shoe
nail. Each of these peices has been oeh''
re.bent and twisted, without the slish'es.
sign of fracture, exhibiting the toughness OF
the old.fashioned, highly hammered, small
bar of Juniata iron, which we were accus'
toned TO meet with % years ago."
The letter of MIR. Ward, says:
uHaving understood that Convention OF
gentlemen engaged in the manufacturing OF
iron was TO be holden at Pittsburg; nave
de,ermined-partly because OF the deep IN
terest I feel in the subject-and partly TO
TO serve nv friend, the ingenious inventor
to call your attention TO Mr.. M. 5. Sal'ers
new process of making ,rrought iron d'reet
from The ore, by singular process, auth an
thracitc or bitumous COAL MIR. Salter is fully
satisfied, from experiments made at New
ark. and Boonton, N. j., and several lntelli-
gent Iron Masters, also, who have seen the
Furnace in operation, are OF opInlon-'ha'
wrought iron may be made by his process at
two.thirds less cost than by any other process
whatever. MIR. Sater feels warranted in say
ing, that iron of the first quality can be made
here or at Boonton, N. j., and delivered in
New York at a cost of s25 per ton. His Fur
mace is adapted 10 ores, yielding ~ per cent
and upwards of iron. 1t consists of triple
chambered Furnace, one above the other
the ore being pulverized and mixed with
hard coal and ground fine is placed in the
upper chamber-where the gases and impu
rites, such as sulphate, &c., are carried OF
at low temperature. From thence it is drawn
through openings in the bottom, into the sec
ond or middle chamber, where the fiuXins
materials are added-thence it is drawn dowr
openings to the lower or pudding chamber
the whole process occupying less than an hou'
and half.
Five mer are required each turn 10 work
the Furnace, and the yield is about 400 lbs
per hour and half. Two anda half tons Goa
are consumed in "a hours The cost OF the
iron will vary according 10 the facilities fol
getting the ore and coal, the cost Of labor, &c.
Former experiments have proved as far a:
they have been made that anthracite Goa
does better as the dooxidizing material thar
bituminous coal, and quite as well as char
coal but the bituminous coal is quite as gooc
Though no beterj as either for fuel 10 hea
