THE CALoRIC ENGINE AND APPARATUS FOR Con-
QUOTING AND REGULATING Motive PowER.-In def
ance of obstacles and reverses that would have ap-
palled stOuter hearts, and forced weaker men to
give up the struggle in despair the caloric engine
is in success sful and practical operation, and the
genius and perseverance of Mr.. Ericsson, and the
sagacity and liberality ofMr. Kitchng, are crown
ed with tiattering degree of success. Their long
and resoute efforts, and the liberal expenditure Of
money which has attended them, promises to
secure, not only the fame of the inventor, but i'm
mediate and substantial returns. Every reader will
rejoice to know this. In every place, where light
compact, economical, and easily managed motive
power is required, the caloric engine is being in
troduced.
There has been added to the caloric engine, ap-
paratus for conducting, distributing, and regula-
ting its power. 1t consists merely of the common
air condensingpump, and air-tight tubing. 1t is al
ready proposed to apply this power to turning the
wheels to the House Telegraph apparatus at the
principal Office in this city, in which several opera
tors constantly at work. and who. of course, re-
quire as many men to attend them. As all familiar
with the subject well know, it is required that the
wheel attached to this apparatus should be turned
at very variable speed which circumstance has
heretofore prevented the application of machinery
to it. This difficulty has been overcome, however,
and by placing caloric engine in the basement of
the building and by conducting and distributing its
power, so that it may be controlled perfectly by
each operator in its application to his apparatus,
great saving NAV be effected and the operator ena
bled to increase the speed of his wheel from ten to
seventy revolutions per minute, uice UerSa and
all this without in the least interfering with his
other duties.
All who are familiar with sewing machines are
we'll aware, that their operation produces a most
exhausting effect upon the operators many consti-
tutons sink at under the ordeal; and all su fer
more or less from the exertion of working the
tread-wheel. The "Song of the Shirt" graphic as
it is, falls short of describing the wearsome suffer
ing, and physical degeneration, which are the re-
suit OF continued labor at sewing machine. Mr..
Carhart, of the firm of Pagan Carhart, Glothiers,
has, both on the score of humanity and economy,
long sought for appliance by which his opera
tives might be relieved-and occupying the upper
part of the American Express Building, in Hudson
street, this firm have ordered a calorc engine to be
put up in the basement, and its power distributed
among one hundred sewing machines by means of
cold condensed air. The power will be separate in
its application to each machine and a single effort
of the foot will regulate the speed from the highest
to the lowest point.
The whole apparatus for applying and distribu-
ting power is simple in its character and opera
on, that its is beyond doubt and it will be
found of the greatest service in tightening the la
bors of overtaxed class of operatives as we'll as
in great variety of necessary labor.-Courier and

New York correspondent of the Philadelphia
Press enumerates the reforms that have been made
under Mr.. Pisbury, and says:
"What is more astonishing than all is that YOU
can now find policeman, if you want one, in some
other locality than round the doors of grog shops
They have ceased to be habitually boOZy, and the
of tobacco longer streams out of the cor
ners of their mouths. Under the iustrous Pills
bury they have become decent, orderly clean, at
tentive, and civil. They do not treat thieves any
better than honest men"
