The COTToS MILLS or NEwBURYPoRT.-Whie the
speed and active power Of locomotives and the pro-
portion of power to tunnaSe OF steamers, are absorb
ing the energies of best-nformed disciples OF ma
teral progress there is astonshngly wide differ
ence not generally known in the economy of the
thousand on thousands of stationary engines IN our
manufactures. Steam power is cheap but, perhaps
few are able to say practically how cheap.
There are five steam cotton-nlls in the miniature
City Of Newbuyport Mass, all managed on the most
modern system, the materials consumed and cloth
produced being recorded each day or week. These
mills are all from to ID years Old were provided at
the outset with the best of machinery, and have al
WAYS ranked as superior in economy to the average
of such mills, although comparisons IN this respect
have never, we hold, been urged with due force and
earnestntss in any manufacturing business. "lthlh
the last eighteen months the proprietors OF four OF
these mills have taken out and exchanged Neir en-
gnes for Others still more modern and we have deemed
the results sufficiently startling to deserve careful
noting the spot; and they are briefly presented
below as belonging to class of arguments which
should arrest the attention of careful managers every
where.
The experiments for such we choose to consider
these exchanges unusually grand scale. The
apparatus employed is in the furhest degree removed
from that of the closet philosopher. To simplify and
condense the results we have reduced the whole d.
rect the work done and coal consumed the amounts
assumed beth the present and previous consumption
being the average for several months, copied di-
recty from the books and we here acknowledge high
degree of courtesy on the part OF the agents and all
concerned in extending facilities for accurate inform
alton.
The Globe Steam Mill of 1920 spindles, making
nm On l., e: orI
fannel, previously burned s., tuns OF coal per day;
now the amount burned is only Al tuns, although the
quantity Of work done has been increased Is per cent
Each pound of coal produces effect 40 per cent
greater than by the former and usual arrangement.
This gain, although exceeded by that in either of the
other mills to be named, is too great to be attributed
to any slight or accidental cause. 1t would be
tremely difficult to anayze the results and assign to
each feature its proper influence; but what deem
the chief peculiarly is the Regulating by the cutoff.
The new engines substituted in all the referred
to were designed and executed by Messrs Carlss &
Nightingale of Providence X. l., who construct style
of engine differing in almost every point from any pre-
yiousy in Combining attention at present TO the
results alone the next in order Of economy the two
Bartlett Mills which are both under management
and are usually cassed together. These contain II 800
spindles and make 10000 yards, or 1900 pounds of
shirtings per week. The fuel burned here has been
a tuns per day for several years, but since the intro
ducton Of the improved engines trihe less than tuns
have been consumed, the work remaining the same,
and the boilers in both these and the Globe Mills re-
naming undisturbed The non-exchange of boilers is
important in showing that the change is due entirely to
greater economy in using and not in any part TO i'm
proved means of generating the fluid. Each pound of
coal now consumed the Bartlett, Mills, is 81 per
more efficient than by the old arrangement, effect
which, although it may be ascribed in part to other
notifications about the engines, must be due in the
main to the feature referred to, the increased effect of
the steam, both direct and expansive, when regulated
solely by the cutoff
To Mr. Geo. H. Corss, who until very few years
since had been engaged in the quite unmechancal de-
tails of country store is due the whole credit of all
the inventions and novelties embodied in these engines
which NAV Justly be held up to the world as among
the finest specimens of engineering skill in existence.
Bv connection with Mr.. Nightingale, who deserves no
small degree ID credit for his enterprise in bringing
forward these improvements liberal scale, one
of the largest machine establishments in America has
been planned erected stocked with the most improved
tools and devoted entirely to the manufacture Of this
STYLE known as the COrlss engine. The fnshng-shop
alone of Corss & Nightingale's concern covers an
acre Of ground.
The Corliss engine is being very extensively intro
duced but in few if any other is it under circum
stances which allow direct comparison with the
performance of other good engines in the mills under
notice. The motive power of whole city has been,
or is being regenerated-for the only remaining mill is
now being prepared for q similar change-and under
circumstances exactly such always longed for
when any new invention appears which makes loud
preensions; circumstances which allow the actual
suits to be plainly and compared with others with
out introducing confusion by other alterations.
II is common practice with these builders, az it
