Singeing of Cotton Stuffs by the gas flame. 
Tue manufactories here are generally closed against stran- 
gers; but I have obtained access to two of them, which are 
highly interesting. I believe the process of singeing muslins 
by means of the gas flame has been described in our publi-- 
cations. Within a year past it has been brought toa great 
degree of perfection here. The process by which these fine 
textures were passed over red hot cylinders uninjured, was 
sufficiently astonishing ; but one is ready to doubt the evi- 
dence of the senses, when he sees a web which is so delicate 
as to be transparent, subjected to the direct operation of 
flame, two or three times in succession, and with no change 
but an improvement in beauty. 
The machine on which the operation is performed, consists 
of an upright frame, sustaining two large rollers, one on each 
side at the bottom, and two pairs of rollers like those of a 
rolling-mill immediately above these, at the top. Between 
the upper rollers, the gas pipe passes the whole length of the 
frame, thickly set with openings serving as burners, so that 
there appear to be from 50 to 100 in the space equiva- 
lent to the breadth of the cloth. In performing the opera- 
tion, the muslin is placed upon the lower roller on one side. 
The web is then passed between the pair above, which serve 
to keep it smooth and prevent irregularity of motion over the 
gas burners to the opposite pair of rollers, and is attached te 
the lower roller on the opposite side. It is then drawn over 
the flame by the motion of the roller, originating in a steam- 
engine and communicated by drums and bands in the usual 
manner. {t was not found sufficient merely to pass the muslin 
over the flame, and therefore another contrivance was added, 
ef great ingenuity, which renders the operation more sur- 
prising. A pipe passes above the cloth in the same direction 
as the gas pipe, with longitudinal slits and openings to a main 
pipe above, corresponding nearly to the gas-burners. This is 
connected with the receiver of a large air-pump, which is kept 
mimetien by thesteam-engine. A partial vactium is thasmain-
