Perpetual Acknowledgements! Steam engines
may cease their labored breathngs, and with all
their adjuncts OF boilers, spark-calchers, smoke
| consumers, and other patent fixtures, retire TO
the rust Of obscurity Torrents need be no longer
damned or doomed TO serviie work nor the
| windmill beat with ponderous strokes the rush
| ing air. Even horse power" shall soon be known
only as measurement OF force and the history
| OF dog-carts shall go down the current of time
with ancient fables illustrated only by fancy pic
| lures. Not only this, but the aboring muscles of
| man may have long holyday his patent reapers
and feld-rakes, his single machines and his hand
organs, shall now all go of themselves" Good
| housewives may set their new churns in motion
with wink, and sewing-machines on the new
| principle shall take away the vocation of poor
seamstresses societies. Mr. James G.. Hendrck-
son, of Freehold, Monmouth county, New Jersey,
| has gone and done it, Alter forty years of pa
| tent whiting" he has made machine that
will not only go of itself" but will compel divers
other bodies TO which il is attached 10 go likewise;
| ia short, il has POWER! The success is in the d.
| rection in which so many have so long labored in
vain, viz: by the use OF arms and balls attached 10
cylinder so as TO keep the extra weight always
! on one side, and therefore TO give the cylinder
constant inclination TO turn round. The machine
requires no starting take away the blocks and it
| goes off like thing of life" The model was in
our Office yesterday, and attached to some clock
work. which IL turned without once stopping 10
| breathe.
We see no reason why il would not go until
worn out. Whether on a larger scale the princi-
| pie would be available, we are not prepared 10
| say; il would be rather awkward TO manage at
first, as the power could not be turned of, and il
would have TO be managed like skittish horse,
e. either " hiched," held by the bride. If il
should take 10 going fast" we think the contin-
gent force acquired by the balls would prevent
their rolling back to the centre |; but Of this we
can Judge better when 1t IS put TO It's speed. Mr..
Hendrickson will take some steps TO remunerate
himself for his years of trial, and, it is probable,
WILL before long, exhibit his model at some place
in the city, where the curious may satisfy them
selves OF its merits. After careful examination,
we can safely say, in all seriousness that the pro-
polling power is self-conaned and selfadjusting,
and gives sufficiently active force 10 carry ordi-
nary clock work, and all without any winding up
or epenishng.-Journalo Of Commerce.
High Price of Coal-Southern Coal Fields.
No coal has hitherto been brought TO the northern
markets south of Virginia; but as no country is
better supplied with coal than the United States,
we have only 10 develop our natural resources in
order TO command an adequate supply. and TO keep
down prices at q reasonable rate The south is
exceedingly rich in mineral treasures Of all kinds
and transportation can be effected at reasonable
rates. The large coal fields Of North Car DINA
will soon be opened, and will afford an immense
supply.
Charleston and Savannah rely mostly upon Eng
land for family supplies of coal but the North Ca
rona mines will supplant this foreign trade
There coal yards OF any consequence in
New Orleans; but conside rable quaniities of coal
are brought down the Mississippi in fiat boats,
and sold out at the Levee by wholesale or retail
The fiat boats which bring down coal for the ocean
steamers moored some distance above the
city and come down with their cargoes as they
are wanted. Owing 10 the fact that there are no
permanent coal yards in the Crescent City, the
price OF the article fuctuates considerably, accord
ing 10 thu stage the water; high and low water
having the same effect there as mild severe
winters In this latitude.
Coal is commonly sold in New Orleans by The
barrel, and fifty cents is the usual price; but last
winter, when the rivers were very low, coal went
up 10 two dollars per barrel, which would b. .q al
10 ten twelve dollars ION. Ii is highly ptuoa.
bic that coal might be shipped from New Orleans
10 New York this winter and pay handsome
profit. II is brought down the Ohio river from
Kentucky well as from other points. There
are large deposits in Arkansas, which might easily
be worked, especially while the demand continues
so great. When all the southern mines are in
full operation, they will counteract the monied
combinations AT the north. Nevertheless as this
cannon take place Immediately, and as the poor in
all The northern cities are likely TO suffer if the
winter should be severe. il might be advisable 10
urge the repeal of the duty on foreign coal and 10
send in petitions 10 Congress 10 that effect and
praying, moreover, that the measure may receive
the earliest consideration OF the approaching ses-
sion-JoHrnal Of Commerce.
