lRoN.-Ihe manufactures OF iron daily be coming
more important With an increasing demand there seems
e be an Increasing supply and the ingenuity of our
trymen is exerng itself TO the utmost 20 produce article,
o. hs material Not only cheap but durable and highly
finished. 10y
Attis moment, remember articles infinitely SILL
perlor IN character to those OF similar kind
IN England, AMI they, we my the expression lie al
tue extremes OF the work shop-axes and door locks
Iii admitted by the English that all attempts on their
part to make good axes have hitherto failed premium
offered for the best model did produce the intended
suit and while her emgrans crowding to Canada
and New Holland, they were unable TO carry with be,
axes with which to bow the woods meath their sturdy
stroke"
In the United Satos necessity the mother of invention
led to the formation of good axes. Like patient men
they keep their temper Our axemen NAV trace their
ieonty, ana attribute their expedition TO the shape and
qnshy oil me axes which our ingenious mechanics have
placed in their hands.
So with regard to locks The vasincrcosc of our popu
taon, and the consequent demand for dY eIlng
created similar necessity for locks; and il is well known
that those OF American manufacture much IN
the imported In this city we have lock-smiths whose
work IS unsurpassed III any country, while the axes ma
nuaclured in our vicinity equally celebrated
Soin the smelling iron Varieties of methods have
from time TO time been tried at the least xnense
The greatest quantity of metal from a given ouaniitv NJ
ore One othe most ingenious operations we remember
a this hme and one in which science has exerte an a.
tonishng influence, is the of the magnetic wheel IN
separate" the metal from the humps of broken mineral
Mines which afforded the best metal were sometimes so
distant from the furnaces that the Transportation amounted
to sum that made it impracticable.
An ingenious person imagined that a wheel nrmed
with magnets, could be made 10 revolvc i'm sucb yav s
10 pick up the iron side and drop i, on The oil,e
This had wonderful effect upon tho expenses of the
furnaces To produce ton of iron il is calculated
at hree tons OF ore required besides charcoal and
limestone, which are also used in great quantities.
The breaking up OF the did exempt the smelter
from being Obliged to throw in large quantities OF stone
with the ore, he could otherwise SEPARATE IN,
from the rock in which il is found.
The magnetic wheel relieved him at once Compora.ive.
~ speaking he was rid OF the score-The magnets how
ever became easily disordercd and to reouch them was

Here, the first fruits Of the electro magnetic theory were
perceived Professor Henry, of this city Gow the able
occupant OF the chair of Natural Philosophy at Princeton

IN restoring the magnets TO- their former state in very few
minutes This discovery has become invaluable to the
turDacemen OF the North where the prncple s no,y re
eognised; and it shews how much after all the monev
making, and money getting portion OF society are deceived
when ihey think science of no consequence any but
men oil leisure. Science puts money in their uocket and
stocks. ~
1t has been study much attended to of late, 10 know
the character and value OF American and foreign ron
compared with each other. -
The consumption ofiron 10 lIssezf -

Character The metal yet be lhorou gy understood
The Baltimore iron is considered the best in e world for
s'eamboas-Asy yet we do moi dbcate wrong iron rails
but probably very shall as machinery will he con-
trived to eqnalze the difference between prices Of Amer
with success at furnaces.
The American iron being melted by the heat of char.
coal Is allowed to be more tenacious than the English
which ia melted with coke.
10 put the matter completely at rest however very in
teresiing experiments have been made at the apartments
oil the franklin Institute under the direction Of Mr. John
son, scientific gentleman The Secretary OF the Treasl.
ry was authorised years since by an act of CONGRESS
10 eXpend certain amount in constructing machines IN
make experiments the enacy of iron and other metals
used IN steam boilers 1t constructed as TO admit
any degree of temperature, up TO 800 deg. FarenlIe
Some interesting results have thus been obtained Tie

Will not forget to submit specimens Of their iron to the lest
OF these experiments
1t also found that American iron was better
than the best British and the best American equally and
