quenuy that most people are more or

but the chemical processes by which
water itself is made an agent of illu

process of development for a number
OF years, are far more out of the gem
eral ken.
Why, yes, | think | understand It, +"
remarked layman with unscientific
temerity. You Just turn the hose on
very hot furnace and collect the
gases that come off.
The layman was right as far as he
went. But If that were all then every
householder might be his own gas
manufacturer. No bills TO pay to thu
monopoly" No disputes as to the
price OF gas, which stockholders now
might like to fix at two dollars, dema.

| Nobody would have to maintain ex-
pensive laboratories and testing sta
lions manned with high-priced experts
| Gas would be almost as cheap as air
| and OF no more value as an illumin-
ant Even as a fuel it would be worth
much, for 1t would be mixed to satur-
/ ation with dead, incombustible pro
ducts of combustion" 1t would, in
fact, be everything that popular fancy
20 years ago supposed water gas TO
be-something cheap, nasty and IN
disable.
Engineering skill has made it some
thing far different. Typical OF the
processes prevailing in an industry
which embraces plants in nearly 500
American cities and stable towns
stands the most famous of all Ameri-
con gas works at historic Point Bree
re on the Skuylkin in the southern
part of this city, on the site OF a IA
nous inn Where General Washington
used to take refuge from the devas
tating heats that sometimes afflict
Philadelphia in summertime Here
was worked out to failure one Of the
most noted examples Of American mu-
! nicipal operation, the Philadelphia
bureau of gas"-a failure so unendur-
able that at last the citizens leased
their plant to private enterprise,
the United Gas improvement com
pany, nearly ten years ago.
Spurred by the incentive OF making
a good showing where the municipal
government did badly the engineering
department of this enterprise has
built up system which is generally
recognized as a leader OF its kind.
/ Though not devoted exclusively 10
water gas making, for a coal gas
plant is included, the Point Breeze
works, one of two connected with the
Philadelphia system, illustrates the
technical usage with remarkable com.
pleteness. Here. is performed the
daily marvel of the conversion OF
thousands Of gallons of water, pumped
from the muddy river below the cliffs,
into what has come to be regarded as
the most satisfactory of Illuminating
gases.
Increased use has followed the per-
fecting of methods. In an age of cleo
tricity water gas has steadily become
popular. The old-time prejudice has
disappeared, for its high Illuminating
power has always presented an IN
anSwerable argument. The quality,
furthermore, OF the water gas is con.
stanuy being improved The basic
principle OF its manufacture is so
simple that very few people nave any
conception CT what has been done and
what is still to be dore.
| As with most great inventions, the
| manufacture of water gas depends in
! he first instance upon a very plain
and easily Ineligible fact Water is
composed, as everybody knows, Of
two parts OF hydrogen and one OF oxy-
gen, the particles being chemically
united. When water is brought into
contact with intensely heated carbon
in the form, for example. of burning
coal or coke-the oxygen unites with
the nearby carbon, giving carbonic
oxide in a gaseous state This union
allows the hydrogen, light and high.
~ inhamable gas, to go free. But It
isn't enough just to pour on water
and draw off an Illuminating medium.
the gas thus obtained won't aiye
light, and its calorific, or heatgivlng
capacity, will be low.
First there is the problem of secuy

proper to water gas free from admix
ture with what are called the pro
due : Of combustion in ether words.

Is necessary to put into the current
OF water gas other gases which have
Illuminating value. The third difficulty
Is to remove from the compound gas

ical elements that are undesirable as
an illuninant but which stiH may

The first two OF these problems
were solved with essential complete.

Lowe plants are now in operation In

consideration is one which gives gas
engineers constant employment for
