the average lift required of pumps
when both We're running was 10 12-10(
feet and when either pump was opera
ted alone the lift was 8 6S-1Oo feet.
The friction head or resistance die
not amount to more than one foot(
IT'D and was probably less than this
Therefore. the total head against which
both pumps operated was about II feet
and for the one pump vas about i0la
feet.
The specifications required that the
pump operate against a head of 10 feet
including friction.
The water pumped was measured
by Weir placed in the distribution
channel Observation showed that the
errors due to leakage IN the septic
tanks and the evaporation did not
per minute
The average speeds of the two
pumps operating together We're SAT and
S52 revolutions per minute respectively
and of that operated alone, S97 revolu-
tions per minute. The specifications
call for speeds of $40 revolutions per
minute.
The two pumps operating together
discharge water at the rate of 2,1134 gall
Ions per minute, and the one operating
alone discharged 1.4S1 gallons per
minute.
The one discharged somewhat more
than one-half of the two due to the
increased speed and reduced head, the
increase in speed resulting from les
sened drop in the transmission line.
The specifications call for capa-
city of 200 gallons per minute for each
pump at the head Of Is feet above men
toned.
1t will thus be seen that the pumps
are approximately one-third or 700 gall
Ions per minute short in capacity when
operating at a head only about two
thirds of that required.
IF the Is feet of head were imposed
upon the pump believe that they
would not discharge much more than
than 1000 or LOO gallons per minute.
This matter should be taken up with the
stand, furnished the pumps under con-
tract with the city, and not thru the st.
Louis Electrical Supply Company.
aside from the shortage in capacity
of the pumps there are certain mechan-
lean defects in the pit which should be
.First-Call the attention of the
Morris Machine Works to the fact that
the bronze shaft does not work we'll in
it's babbitt bearings. 1t is customary in
large submerged centrifugal pumps to
use lignum vitae bearings for bronze
shafts.
'Second-The Alignments of the
shafts are not good, and the shafts do
not run true. An additional bearing on
an I-beam between the two now in the
pit would be an advantage. The REM
edy in the pump above suggested will
also help this matter.
"'Third-The action of the floats in
on the whole load Of motor at
once is severe, especially on the engine
at the water works. As soon as can
obtain information on slow-action floats
will report further.
"I believe that the Morris Machine
Works will be willing to meet you in
the pump question, because they can
not afford to do otherwise" u
Farmers Present Petition.
The petition announced some time
lgo as to be presented the council at
It's next meeting was brought before
he body Monday night. Five hundred
signatures Of farmers were appended
20 the document asking for suitable and

! resolution covering the point, and
asking that the mayor appoint select

port to the council at the earliest con-
senience. Mayor Jones appointed Mr..
Kirby. Mr.. Henry and Mr.. Greene.
To Remove Public Fountain.

ion calling for the removal Of the pub

ordered it removed.
