More crop failures on irrigated
lands may be traced to faulty level
ing than to any other cause under
the control of the farmer. Poorly
leveled lands are expensive to irri'
gate, both with regard to the amount
of water and the amount of labor re-
CURED: and In addition, the plants in
the different parts of the field are SO
unequally watered that unsatisfactory
crops are the result. The machinery
necessary for leveling on the small
farm Is simple and inexpensive. and
should be kept in order that all
spare time of men and teams can be
used to the best advantage. On the
small farm all that Is necessary Is a
small scraper, a pillow, and a plank
drag.
In leveling, the first thing to do Is
to decide Just how the land a be put
into shape by moving the least
amount of dirt. A good way to begin
Is to set stakes to represent borders.
and see how they may be located in
order to obtain the best results. II
is not necessary that an entire field
should be level, but only that the soil
within a border be SO; and each bord-
er may drop lower or rise higher than
the one adjoining, without any serious
inconvenience in either seeding or har-
vesting. Borders should not be spaced
too wide. Forty-five to sixty feet will
be a good width If the field Is at all
%sloping; and it is not best to make
them more than 100 feet apart. even
when the land is level.
Locate each border definitely, and
mark it by throwing up a couple of
burrows. or in any other way that is
convenient. Then beginning the high
end of the field, work out the first
border. taking all excess dirt from
the high places and spreading 1t
where needed in the low places. In
sandy soils the borders should not be
more than 200 or 300 feet in length,
but on clay soils no limit need be
set for the length. For the location
of the borders, especially If they are
long, it Is almost necessary that a
level be used. These may be pur-
chased for about SIS to $40. Perma-
nent borders should be built at the
time of leveling. These should be
just high enough to control the
movement of water, and should be
wide enough to prevent any danger
of their being dragged down by ma
chinery or washed down by the run
ming water. A convenient and very
satisfactory way to build such Dor
ders Is to drag up the dirt with a
scraper and deposit it along the lines
OF the border; where it should be
smoothed into the desired shape.
If the borders are built with a
broad base and slowly sloping sides,
crops can be grown along the sides
and top without n difficulty. The
base of such borders should not be
less than eight to ten feet wide. After
all borders and the checks or cross
borders are complete, it is best to
go over each section of the field and
true up all slight inequalities that
may have been missed in the first
leveling. Here again the level IS of
great value, as 1t points out these err.
rors much more closely than the best
trained eye If there Is free and
abundant supply of water, and the
field will not need it for some time. it
Is well to give 1t a trial irrigation;
making a note of all the points that
are either low OF high, and correct
Ing these as soon as the soil Is dry.
One thing that must be borne in
mind Is that where any large amount
OF earth is hauled into a low place,

for this and a slight excess of soil is

for this reason it is we'll that the
