from dirt and sand. II Is not n good
practice 10 have the strainor OF the
same length as the depth Of the water
bearing stratum as the water level is
generally drawn down by the pump 50
that the strainer may not be utilizing
It's FUN length or Il may destroy the
suction OF the pump to "a certain eX-
tent In which case the efficiency OF
the pumping plant viii Doe lowered
As an example Il may be stated that
FOR "a gravel bed go feet In depth "A
I2-fOOt struiney should be used or even
less and the stralner extended 10 the
bottom of the bed SO that there will
be depth of gravel above the top of
the strdiner. one Of the best strain
ors ia use in this section is the porther
strainer This strainer works add
mlrably we'll and should be used
where the deptI Is not too great. In
the deeper wells where there would
be liability Of the strainer being
pulled apart other types OF strainers
are used. The Porcher strpiner Is
adapted 20 this section OF the south
west and will answer very satisfac-
torlly for most wells. The Porcher
stralner is a heavy galvanized tube of
varying length according to the depth
OF the water-b bearing stratum.
This strainer Is rlyeted to the bot
tom OF the standard casing ana low
cred inside of the first easing puC
down. This latter casing Is then
pulled up. leaving The straiher eN-
posed. For wells over 30 fee m
depth &c Is not practical 20 attempt to
! pun mp the casing apart. On the
edge OF the artesian basin near RIOS
we'll and Artosia many wells have
been sunk 10 depth OF 1000 ieet,
the water rising 10 Within rs or 30
feet from the surface of the ground.
| These wells give abundant supply Tor
pumping and a great many wells are
being utilized On this manner. Some
OF IN flowing wells in that section
cease TO flow curing the period from
| June 20 August and this temporary
cessation Is tided over by installing a
pumping plant TO insure a water sup
ply for crops during this inactivity
iOf course, there are numerous wells
which maintain a nearly steady flow
! Throughout the Irritating season and
such measures are not necessary.
The Cost Of Pumping for irrigation.
The first question confronting the
/ irrigatOr who wishes TO pump water
Is, how much water is needed? In or.
der 10 determine this Il is necessary
TO know tbs acreage 10 be watered,
crop on crops TO be raised, nature Oi
the soil and the pecullarlties OF the
climate: In other words the periods
and amount of rainfall Say that q
man wishes 20 irrl-ate alfalfa. EX-
perlence shows that IL takes between
40 and as inches OF water for the sea
son. using S or 6 inch irrigations, de-
pending on the soil II Il takes an
hour and a half 20 ir-lgate an acre %
VIII require head Of al least two
ANA One-half cubic feet per second 10
accomplish this or al The rate OF 100
gallons per minute
The next iuctor figuring IN the cost
Of pumping Is the height through
which the water rs no be lifted. This
IL the factor which determines wheth-
Ter pumping will Doc profitable or not.
as the cost Of fuel has been found
10 vary almost directly as the lift
For example. A man lifting water SO
feet will pay twice aa much for fuel
las one lifting water only % feet. The
total cost 0l pumping does not vary
direCtly bat Increases rapidly with
the increased Mn, hence the kinds o
