lively short period to a demand equal
ing a rate of 100000 to 100000 gal
Ions during "a hours, Which would be
the volume required tj MAINTAIN from
nine TO twelve strong fire streams.
The duration of this maximum de
mand would never, in all probability,
exceed six or eight hours, so that the
extra volume required during lie
largest fire might not exceed 100000
gallons.
This excess volume above the regu-
lar daily demand may be obtained
from a supply held in a reservoir or
a water tower at a high elevation
near or within the limits OF distri-
button, or It may be furnished by us
ing the reserve capacity Of the pump
ing machinery to deliver it from
the source, ample provisions having
been made for obtaining Il. The
former is by far the better meth3c
where II can be arranged.
The pumping machinery and mains
must be proportioned to accommodate ?
this increased demand
Fire Service.-The very best au-
thorities fix the number of fire streams
necessary for city OF 10000 at from
eight to twelve, and for city of say
10,000 population at from six to nine.
The average, therefore, for Ardmore
in the immediate future. say during
the next five or six years. would be
say eight strong fire streams, calling
for water at a rate of about 1900, ,00O
gallons daily and at time ten or
twelve years hence for ten or twelve
fire streams calling for water at a
rate of nearly 100000 gallons dur
ing "a hours.
These volumes, II must be under
stood, are in addition to the regular
daily demands and represent the
maximum requirements liable to oc.

Fire Hydrants.-My estimates call
for placing along the mains an aver
age of about eighteen (1S)
fire hydrants IL each mile. This IL
about twice the number often placed
and | advise this solely on the plea
that the best results and the greatos'
economy must follow and for the fol
lowing reasons:
The best six 60 inch FIRE hydrant
set, connected, ready for use will cos
less than forty $40 dollars ant
with the care and attention it de
serves will last thirty (3O) years o.
longer. with small outlay for repairs
The very best four-ply rubber linet
hose costs about one (s1) dollar pc
foot or fifty (S5O) for one fifty-foo
length.
This with the best of care will las
an average of about five years, Will,
the fire hydrant lasts indefinitely anC
costs less.
Spaced as suggested on third th,
length of hose will render better ser
vice and you will be able to reduc,
the length of hose you carry in stock
and consequently your outlay for hos
proportionately.
If fire hydrant be located imme
diately in front of large fire, or /
one be disabled, the distance between
the two nearest hydrants is oftel
doubled, requiring twice the lengii
of hose, and reducing to about one
half the effective pressure at the nol
zle. By the spacing which I suggest
600 feet would be the greatest dist
ance between hydrants under the cil
cumstances.
Shorter lines of hose mean les
time in getting a stream on the fir
and a greater effective pressure. Yo
. can appreciate the force of this whe

of 105 pounds at the fire hydrant I
