The individual system, also TO be
demonstrated calls for piping water

method Is desirable i'm districts wnerc
II small amount of water Ia desired TO
do large amount of hrieating. There
Is no loss from evaporation or seep-
age and only the ground I'm which the
tree grows receives the water The
cost OF iuatnling this systcm is much
larger th9n for the open ditch or flume
system. but thc difference Is soon
made M on the cost or watoF or
where n Is paid for by the acroioot.
Sub-Irrigating by means Of open
dItches will also be shown The ditch
cs arc OF such depth that the water
Is absorbed without molstening the
surface. This method Is advantageous
where soil has a tendency TO bake
or become crusted after watering.
TWO tracts Will show the prnctlca-
bility of watering steep land I'm open
ditches. The incllnes on one tract are
from 30 10 45 degrees. Tho other
shows the terrace system, water be
Ing dropped from one terrace to the
other II will he demonstrated that
land can be irrigated by this plan
without washing or erosion.
One form of the corrugotion sys-
TEN is applied TO soil whore the land
slopes In moro than one direction, the
ditches being made to follow the natu
raj contour. which needs no grading.
Water Is supplied through one box and
the ditches spread out In fan shape
over tho land.
For eeets and Alfalfa.
Another plan OF the so-called cor
rugated idea. best adapted to sugar
beet. alfalfa and grain lands with n
gentle slope shows water distribution
by means of V-shaped ditches or rills,
. 1.3 inches deep and about is inches
apart. The margin dixie or basin sys-
TEN of irrigation shows ditches built
surrounding the tract OF varying size
running from ono acre 10 10 acres in
area. To practice this method sue
cessfully the land must be level or
have only gentle slope Sufficient
head may be had in the water itself
to cause II to spread over the ground.
On another tract is the dixie system,
which follows the natural contour OF
the land. This method IS adapted TO
ground with slope, but Is not prac-
tical for level land. II is similar TO
the side dixie system. but the first cost
cost Is less and the results not as
satisfactory.
The dixie system is seen 10 best advan-
tagc on ground with a uniform slope.
The method Is to build dikcs 100 feet
apart from eight 10 II inches high.
depending upon tho chercter of the
soil. Water Is taken from the head
ditch and spread In a sheet over the
areas between the dikcs. The sur
plus passes into a ditch and Is carried
TO the next area.
The sprinkler plan calls for spray
sprinklers arranged between the trees
or vegetable rows and so placed that
they water all Of the ground. This
system can be used only where water
Is supplied under pressure.
Another system Is TO distribute
water TO each tree in an open flume.
The water is supplied from a head
ditch. This IS similar to the piping
method to individual trees, but is
waste OF water, though the cost of In
stallatlon is less

charge OF the work. and practical irri-

of the United States and Canada in
explaining the various methods OF
watering land to obtain the best re-
suit at the least cost.
