has proven more satisfactory in the
prevention of sinking smut of wheat
and the covered smut of barley.
Equipment
A tight, clean floor or wagon box
or a piece of canvas about ten feet
square, upon which the grain is
piled.
A large blanket Or canvas with
which to cover the grain.

The seed should be thorough1v
cleaned from all foreign material
(chaff, stems, smut-balls, weed seed,
etc in the tanning mill and then
wagon box). The formaldehyde So
luton is poured from the bottle into
the hand sprayer. The grain is SHOW
eIed over while a man operates the
sprayer, holding it close to the NOV
ing grain (thus avoiding the dis
agreeable fumes of the Tornado
hyde). Spray the grain as it is shov-
eled over until the proper amount of
for!nal6ehyde has been applied, APP
plying one stroke of the sprayer to
each shovel full of grain. Then pile
the grain and cover completely with
a canvas or large blanket for five
hours (four for wheat), thus permit
ting the formaldehyde fumes to act
on the smut attached fo IA
grain. At the end of the required
time the pile is uncovered and the
grain spread to air for several hours.
1t is then ready for the seeder or
may be sacked and stored until seed
ing time. Old sacks should be thor
also be disinfected. Use 25 per cent
additional seed to offset loss due to
weak seed germs.
Smut-balls must be removed before
treatment. They may be 1oated out
in case the tanning mill does not do
good work.
Keep the grain moving while the
formaldehyde is being applied, thus
insuring an even application.
After spraying, cover the pile with
a tight canvas or blanket; the fumes
must be kept in the pile of grain
for the required time.
Formaldehyde is poisonous-keep
Treated grain, after it is thoroughly
aired, is not poisonous, however, and
may be fed or used for human con-
sumption.
wet" Formaldehyde Method: The
wet" or sprinkling method Of ap-
plying formaldehyde has been in use
for many years and has given uni
form satisfaction. When but a small
amount of grain is to be treated, and
the seed grain contains considerable
litter, 1t may be slowly stirred into
the formaldehyde mixture and the
foreign material diseased grains,
weak germs, etc. fioated off during
the process of treatment. With
larger quantities of seed grain it is
advisable to thoroughly clean the
seed before treatment. The clean
seed is then placed in wire screen
submerged in the formaldehyde mix
ture for the required time: In either
case, however, the grain becomes so
swollen in the process or treatment
that it will not run through the seed
or. Drying the seed necessitates con-
siderable trouble and loss of time. In
addition, precautions must be taken
that the wet seed grain is not sub
jected to freezing, since the swollen
germs are very susceptible to ex-
remes Of temperature. II the wealth
er is wet and warm at the time or
treatment the seed may sprout be
fore it can be dried. The method is
presence of considerable quantities of
water about the seed room.
