AT First skilled glass blower
uorS;o~af4 needed only one or
two unskilled assist
ants to clean his blowpipes. Later,
molds were introduced to aid the blower
in shaping his articles Still later
mechanical devices were used with press
ed the simpler articles into shape with
out the need of a blowpipe. Finally
machines were produced which actually
blew glass. These began to be used in
1895. and the first ones dispensed with
the blower as such, but still required the
skilled glass maker to feed the machine
and operate the pressing and blowing
levers In 1898. an automatic bottle
blowing machine began to be used. This
required skilled machinists, but no glass
blowers of the old type. Since then
many other machines have almost done
away with the need of hand work in
ordinary glass manufacturing. and the
output of glass has been multiplied be-
bause of the ever-increasing demand for
new articles made of glass.
In Europe several uses for glass have
been discovered which are not as yet
recognized in America. There are glass
telegraph poles in use in Frankfort, Ger
many. which it is believed will become
popular in other. parts of the world. The

these poles is strengthen by the utiliza-
ton of strings of steel wire in their
composition. 1t is said that in tropical
climates. glass telegraph poles will be OF
value because they are impervlouS to IN
sects while in other climates they will
have the advantage of not being affect
ed by changes In the weather. Another
new use for glass, which it Is believed
will eventually become practical, is the
making of glass bricks Tor, payements.

has not been satisfactory. According to
report given by an American consul at
the request of American, glass manu-
facturers, they are being taken up be-
cause they Clipped at the edges and
sometimes the bricks split through their
full length. 1t is believed. however, that
a means will be devised to render glass
bricks more durable and they will COM
mend themselves on sanitary grounds,
because of their non-absorbent qualities.
Glass water pipes are in use in Europe.
They are covered with asphalt TO make
them more durable, and it Is claimed
that they possess many qualities that
make them superior to clay and iron.
With the increased facilities for manu-
featuring glass such uses will no doubt
become more general.

and this wear the number will be much
greater. This does not lessen the num-
Der of lamps in use. On the contrary,
the demand for lamps is greater than
ever before. In the rural districts more
lamps are used in proportion to the pop
ulation than formerly because the mod
ern former does not go to bed with the
sun. On the contrary. he is likely to
spend his evenings reading, and therefore
demands as good light from his lamp as
the gas and electric systems furnish to
the city resident. Consequently improve
ments are constantly being made in lamp
construction. One of the latest is the in
vention of a one-piece glass lamp, which
does away with the separate brass COL
ar which so frequently came loose. AL
though this new lamp has been on the
market but a short time, 1t is said that
the demand for 1t already is in excess of
the supply and for the last three months
!, orders have. been piling up at the fac
tory having the right to produce it. In
stead of being separate piece. the brass
collar is. welded into the glass of the
lamp ITSELF, thus overcoming one of the
chief dangers OF the kerosene lamp.
Efforts are continually being made to
improve the quality of glass so that 1t

to housewives d secret for toughening
the lamp chimneys and thus lessening
the breakage. The chimneys should be
placed in kettle with cold water suffi-
cient to cover them. This should be
brought to boil and then removed from
the fire and allowed to become thorough

and wrapped lin soft paper and stored

this simple process will greatly lengthen
