is heated red hot, when the gas bursts out

coal when on the parlor fire. The gas
passes of through pipes. A ton Of coal
will make 10000 cubic feet of gas. The
gas as IL leaves the coal is very impure

This cools tho gas, when good deal Of tar
condenses from 1t and runs down to the
bottom of the perpendicular pipes. This
tar is the ordinary tar which you zee

station metre, then through the mains and
pipes, till it reaches the gas jet in your
room. Then 1t burns while You all swear
and scold because il don't burn better
What makes gas burn badly sometimes
This is the reason: it Is not properly
distilled after leaving he coal. They don
condense ii enough, don't wash 1t enough
and don't change the lime often enough
Again, sometimes it is so impure that a
good deal of impurity condenses on tho
sides of the pipes as they leave the big
mains and come into your house. Don't

burns badly, and poke long wire through
the pipe, and then pour alcohol in I? This
wire clears out the deposit. and the alcohol
dissolves it, and it runs oil into the big
supply pipe in the street. In cold weather
I the gas condcnses more in the pipes than
in warm weather. This is because they
cent get it perfectly cold at the gas works,
and when it runs out through the frosty
pipes, it condenses more. Where do they

Brunswick. when the canAl-boats are

keep the coal in the retort five hours, then
pull it out. 1t comes out u live mass of

Homeopathy having become quite a
successful system Of medical practice, we
have thought it might be interesting
to many of our readers 10 note the following
facts, which we gather from late authen-

now behold its roots spreading into all
countries. II is naturalizel in Austria,
Switzerland, Prussia. France, Italy,
Russia, Germany, Spain, Brazil, America.
In New York alone upward of 400
qualified practitioners dispense it; In
France about 800. In England several
hundred medical men openly practice
Homeopathically, and the number is daily
increasing. These medical practitioners
and their lay supporters promulgate their
principles through quarterly and monthly
journals There also six Homeopathic
