Secure enough garden soil to fill
both cans. mix it thoroughly and sift
it to remove pebbles and clods. Fill
both cans level full of loose soil,
which should then be packed by jarr-
ing each can three times on the ia
ole or floor.
It is important TO have the soil
packed alike in both cans. Weigh
the filled ms, and If one Is heavier
taan the other, take out enough soil
to bring them to the same weight.

set them aside for the corn to grow.
Whenever water is applied. to the
can containing corn, an equal amount
should be applied to the otser car
in order to keep both soils in about
the same physical condition.
When the corn Is three ol our in.
ches high, wet both soils thoroughly,
allow the cans to stand until water
ceases to drip from tie bottom.
weigh them, and record their weights
separately. Set both cans in a warm
light place where the coin will con

Weigh the cam twice On the fol-
lowing day-morning and afternoon
and record the weights. Keep this
up for three or four days. or until
the corn begins to suffer from lack
of moisture. Water again and con-
tinue as before.
You will probably find that the can
containing the glowing plants loses
moisture much more rapidly than the
other.
in another way by using flower pots
instead OF tin cans. When the corn
is three or four inches high, get two
lard pals or cans just large enough

Mark on the outside Of the pals the
depth to which the pots will extend
on the inside, and at point one inot
above each mark make a dent which
can be distinctly seen on the inside
OF the pail.
Now fill each pail with water up to
the dent. water both pots thoroughly
