| After series Of complicated experiments of sew
eral years continuance and great expense. the sub
scriber obtained Letters Patent from the u States
m March, 1918, for an improvement in the Gas ap-
| paratus, since which time his cndeayors has been
unceasing 10 introduce it into the manufactures in
tAs country-but owing 10 the high prices during
the war OF tho materials used in constructing the
apparatusthe limited and prccarous supply of Goals
from Europe, and the difficulty ofiransporling those
OF Virginia coast.wise during the same period, to-
gether with very circumscribed knowledge in the
public oh the subject of Gas Lights, has hitherto
prsyented the Introduction Of them generally in the
United States But Che difficulties incident TO state
et war being removed there is 70 other impsJimen,
than the want Of information on the subject 10 en-.
sure their immediate introduction With ,nmenoe In
dvidual and public advantage. IL therefore be-
comes the duty Of the friends OF Science and the
Arts, 10 use then best endeavors TO inform the pub
lie mind and tlvse hose interest is concerned, 10
take some pains 10 obtain knowledge of this valu'
able improvement, especially since the general IN.
PRODUCTION of this method (on less improved pan)
OF lighting the manufactures in England--the light
ing OF the Parliament House-sevcral Theatres
the streets OF London, (Which is now in progress)
and all the large establishments where much light is
required, furnishes practical proof OF its utility.
The Wenscutt cotton factory near Providence is
the only where a fair trial has been given to the
Gas Lights in this country. where it has been in op.
peraton for the two last winters, 90 tho great salts

ter which were remedieG, and experience has fur

tained that three chaldron, Of coal, which If laid in
at proper season, would not exceed Si2 per chal'

And 6 cord of pine wood at SIS per cord. lS
which would be S54

per night, for $50 nights, (about the
number of working nights in the sea-
sony which is 1875 lbs. at f6 cts. per lb.
amounting to S3l2 so
making the saving in favor Of the Gas Lights Of
$3.50 so per year, or more than four.htths of the
expense, exclusive OF the convenience and soefcir.
cumstances vastly more important than the saving.

Mr.. DAVID MELVILLE,
SIR-Your favor OF the 9Th inst. is before
me, and beg you to accept my thanks, for
the enclosed cneravings Of your apparatus for
the Gas-Ligh,s. The prin, is very handsome,
and does good justice to your apparatus.--
When you were so obliging as to shew it to
me, during my visit at Newport last summer,
was agrccably surprizcd to sec an apparatus
SO perfect, contrived and constructed IN this
country, where the subject OF the Cas-Lights
-. l.. 4 r~.I hap in
think your apparatus'simplc, and chectual,
and well calculated to':hc purposes OF manu-.
featuring establishments and tho ha~cs which
you showed me we're brilliant and burned
withou, smoke OF smell.
Nothing but general knowledge OF the
Gas Lights is necessary 10 introduce them In
to the large manufacturing establishments,
which are now becoming SO numerous IN our
country.-They have the strongest trecommen-
dation which can address itself to practical
men, namely economy. Those who feel par
iicularly interested, to know the details OF the
subject, may hnd all the information which
they can reasonably desire, in very elaborate
and minute reports, drawn up from actual
experiments, made on q very great scale, in
one OF the largest manufactures in England,
by Mr.. MURDocK, and in various papers By
Mr.. Cook and others, for which references
may be had 10 Nicholson's Journal, and other
periodical works on science and the arts. Ii
will be found by referring 10 these and other
similar sources of information, that, the saw
ing, produced by the Gas Lights, as subsi-
imc for oil and tallow, is very great, aud in
large establishments amounts TO heavy sum.
IL is probable circumstances in this country
might produce Some variation in the result,
the degree of which experiments alone can
determinc-Thc Gas Lights are probably
les. adapted to private families than to public
establishments, because the care end skill
which arc requisite are more than csn be rca-
sonably expected among common domeslicS.
But in large manufactures, the business OF
preparing the Gas and Of attending on the
