en- to determine at what level the
headgates should be placed.
The system above outlined Is appli.
cable to the individual users of water
from the various bitches. As an Illus

ion OF the water made in this manner
and yet one Of the users, provided he
u At some distance from the point OF
division, may not aet his proper share
on account Of the loss that ensues in
the running Of water for anv consider
able distance. Statement was made
that small stream loses relatively
more than large stream OF watet.
It wss also stated that It 10 econo MI

supply would thus be secured. For

It is nut economical to run too small
a stream, ~ the wstei runs more slos :
ly and consequently more Is lost bY
seepage and evaporation. Professor
Carpenter advises using more water
1t . time and not 50 often, where
economy in quantity ID desirable.
A number Of tests have been made

through evaporation, ssepagA ~
other caujes and II Is found to be ocn-
siderable. Statement was made that
considerably more water wss required
In . new country than In one In which
Irrigation had been practiced for
years. 1t takes about one foot Of wa
ter to soak three feet Of soil.
The underfiow and the laws govern
Ing under ground waters are much the
same as the laws governing water on
the surface. They flow In much the
same direction, although not with the
same rapidity. Fluctuations in the
water level OF rivers and canals Affect
the height Of the water table under
ground. While considerable loss In
water may be avoided, vet great deal
more water is necessary for use than
that which is actually used BY the
plant itself. Evaporation, seepagc i,
waste and other causes tend t0warcs
this end. Statement was made that
one pound OF wheat or hay required
three hundred pounds Of water for its
growth and that seven or eight, incht =
of water had to be actually applied to
crop Of alfalfa for the plant requ.r;-
ments irrespective Of water wasted,
hence the deslrability. Of uniform
depth OF Irrigation, smooth fields,
quick application, etc. Stfess was
laid on the proper preparing of the
land for irrigating and proper location
Of laterals 80 as to secure the best re-
suits. =.
The experience in the valley Of the
Poudre is that 1s inches Of water a e
required for the raising Of the crop in
one season besides the rain fall. Some
extravagant reports have been made
relative to the duty Of water, but this
is often explained by two crops having
been raised in one year. In northern
Colorado cubic foot OF water is rat
ed as sufficient for So acres. but 200 to
$50 acres are now being Irrigated With
this quantity. The amount Of water
in soil, its relation to growth of the
plant and the temperature Of the
soil itself were fully illustrated by
charts and explanations made by Pro.
