in their extensions now. II Black
foot selects the steel piping, the sys-
tenn can be completed for about
$4,000. If they use the cast iron
pipes, it will cost about 1918, 1000.
The council worked for a long
time Wednesday on a plan to divide
the pipes, using cast iron pipes for
the mains and the steel pipes for the
extensions where it is likely to be
taken up and replaced with larger
pipe in the course of ten or twenty
years. That would call for seven
miles of cast iron pipes of the larger
sizes ranging from sixteen inches
down to ten inches, and ten miles of
the smaller sizes in the steel pipe.
For fear they would have difficulty
in selling the bonds and in order to
get definite proposition, they asked
some of the low bidders to modify
their bids so they could tell lust
what they would do the work for,
supplying the combination of cast
iron and steel pipe and to name
the amount in dollars and cents pay
able in bonds.
Some of the other things the coun-
Gil had to determine was whether
they would take an auxiliary engine
OF the DIESEL type which they could
use altogether in place of the electric
power in case the power rates go
high or Marine engine that is less
expensive, but somewhat better to
use In case of an emergency because
1t can be started more quickly than
the DIESEL. Then there are differ
ences in the kinds and types of
pumps to be used. The council de-
cided that they wanted the Turbine
pump, the kind that handles the
water by means of the whirl that
starts 1t thru the pipe. They have
studied these matters for long time
and are planning for futures both
with cheap electric power and with
an electric power that is so expen-
slve that they might want to QUIT
using 1t and rely entirely on their
DIESEL engine.
The Study of Hydrants
They have given a great deal Of
study to the different tyes of hy-
arants that are obtainable. After
they had studied the question for a
year or so and the engineers had sub-
hiated their plans, calling for about
| 20 new hydrants, and using twenty
our OF the old ones, they submitted
me matter to committee of fire
Underwriters to see if they were
ADOPTING the right kind of equip
nent to get the lowest possible rate
u insurance and there came up the
'tudy OF auxiliary valves and the
'alve seats in the hydrants them
ewes and they found there was con-
lderable difference in the amount
i fire pressure they would get by
he selection Of valves and valve
eats. The fire underwriters ap-
roved the hydrants they had
dopted, but recommended that they
laKe 1t l06 instead of 100. A good
re hydrant has real works in it
nat control the valves. There are
aives that can get slightly choked
'ltn sediment and be leaky and dam
