self ample proof of efficiency of, and
necessity for such inspection. That
| milk from COWS that have not been
tested for tuberculosis is dangerous is
| recently shown in the analysis Of III
samples taken from milk cans In the
city of New York, out of which Is per
cent contained tubercular germs. It
has recently been estimated that fully
ninety per cent of all cases of tuber-
culosis in the human family is due to
milk infection. I mention this simply
to emphasize the necessity for main
tanning the inspection. While it is
possible under our present system for
our ice cream manufacturers to use
cream from COWS that have not been
ed not to do So"
The mayor also takes up the neces-
sity of charging and improving the
water publication plant, and says:
Scientific tests show that the filter
still removes SO per cent of the. impur-
tiles which it is all it was ever expect
ed to do. The increased amount of
sewage thrown into the river makes
the per cent that the filter fails to
remove dangerous. While the water
in the Red river at the present time is
purer than in the Red Lake river,
our present supply conditions are just
as apt to change, as in the other case.
To make a change in the intake an
has been suggested would mean the
abandonment of an approximately
$1OO,0O investment, which would
mean an enormous waste. The prob
present supply, so that all impurities
can be removed. I therefore request
ed the assistant engineer, Ray. E.
Wickham, to investigate such methods
OF water publication as might be used
to advantage as an additional means
Of removing all impurities. After ex-
tensive inquiry, he found system
that has recently been installed In the
city of Lindsay, Ontaria, that in my
judgment is just what we are looking
for and in his communication from
the mayor Of that city, quote the
following portion A. 1
The plant has been running since
the end Of October and has proved
very satisfactory. 1t does the work
all right and meteorological tests
show a reduction from as high as
1000 in raw water and 80 in the ozon-
lied water-there being no uathogenic
or intestinal germs in the treated wat
er. As regards the cost of this plant,
it was exceptionally low owing to the
fact that Mr.. Bridges who installed 1t
was able to utilize q large part of the
70 ia hn 3fx,
for one-half million gallons daily ca
pacity is $3.50. The cost of operat-
ing it is less than fifty cents per mil
lion gallons. The question is so sim
pie and easily regulated that the at,
tendants at the pump house have been
able to run it without outside expert
help. As matter Of fact it Is practi-
cally automatic in its operation: I
have no hesitation in recommending it
for the purpose of purifying. munich
pal water supplies. While its cost is
only a fraction Of the slow sand filters
to build, it Is no less economical in
operation, while the results are very
superior to those of liberation since
besides destroying bacteria, it removes
the color, taste. and smell Of the
swamp waters we have to deal with
'ThOse who are familiar with chem
istry can ready see that the process
is very feasible and that there is no
question about that part of the puri-
fication. The process in short is as
follows: ozone is concentrated from
oxygen and is produced jor this pur,
pose by passing air through the silent
discharge of high tensioned electric
current, which is then drawn by sue
ton into the OzOnizer. From here the
ozone and water to be purified are
passed through layers of fine gravel
SO that every drop Of water comes in
contact with the ozone. Ozone has q
great afinitl for carbonaceous mat
ter. The bacteria which are compos-
ed of about eighty-six per cent of wa |
ter and carbon are readily consumed
by the ozone, forming carbontc acij
gas, which escapes in the air and the |
excess ozone is taken up in part by
the excess water, giving 1t sparkling
appearance. This absolutely eliminates
or burns up" all of the harmful bac-
eteria.
s'This method of publication seems |
we'll ADAPTED for the conditions we
have to combat, the cost !of installa-
tion being low and with our present
equipment; will take but slight remod- /
cling to make the change. It may be
of interest to state that he city Of I
Paris, France, is at present installing
an ozone publication plant with q
daily capacity Of 100000 gallons.
In Europe these plants are more num-
erous than in this country, and while
comparatively new. are evidently on q
practical basis.'>
