home; he wants to see uses for them
elsewhere.
There are twenty uses to which cleo
tricity can be put in the dairy, the
most important being to operate
cream separators. churns, water
pumps, milking machines, refrigerat-
ing machines, milk clarifiers, Pas
teurizers, and milk-circulating pumps.
The electric motor is especially val
uable for a cream separator, as it's use
lnsures a constant speed and a stand
ard test of cream. Nor is it prohibi-
tive in cost Tests have shown that
the cost to a farmer who separates
300 pounds of milk q day is 2.2 cents
per hundred pounds when done by
electricity, and Al cents per hundred
pounds when done by hand, saving
of practically 2 cents per hundred
pounds for the electric driven sepa-
rator.
The advantage holds good with
other appliances. The size of motor
used for driving churns ranges from
Il to horsepower.
The complete cost averages about
one cent for every 10 pounds of but
ter churned and worked
The situation in regard to the milk
ing machine is most interesting Tests
made on an S-machine milking equip
ment, driven by a 3-horsepower mo-
tor, indicate that the power cost is
about mills TO the COW, with cleo
tricity at 10 cents a kilowatt hour
The complete equipment cost $500,
and with it from 80 to 100 cows are
milked twice day.
The dairyman who made the tests
asserts that the saving in labor cost
in eleven months paid for the equip
ment. Eleven men were formerly re-
quired, but with the aid of the milker
the work is now done by five
The advantage of the electrically
driven milking machine is that one
man can tend to two machines, which
will milk about 22 cows an hour The
average farmland will milk about six
cows an hour. The labor and power
for the 2-machine equipment is 81
cents per COW, for the 6-machine, 81
cents, compared with 2.5 cents per
COW for hand milking
There are over thirty applications
of electric drive in the barn and field,
among the most important being
water pumps, feed grinders. corn
shelters, ensilage cutters, grain eleva-
tors, concrete mixers. grain threshers,
grain graders, bone grinders, hay
hoists. hay balers, and clover hullers.
Feed grinders require motors rang
ing from to 10 horsepower, the
larger ones from 10 to 80 horsepower.
A farmer who has 500 bushels of corn
to grind in a year. and who lives n
miles from town, will find his electric
grinding costing him 90 cents a
bushel. The cost at the mill in town
is cents, an advantage in favor of
the town mill of a cents a bushel.
However, this is assuming that the
motor is used exclusively for this one
operation. But If only one-half of
the motors time We're chargeable to
this operation the charge for power
would be cut in two and the total cost
for the home grinding would be 7.O9
cents, a difference of 81 cents a
bushel in favor of the electric driven
home grinder.
Personal Danger Is Lessened
In driving ensilage cutters, husk-
ers shredders, threshing machines,
and clover hullers by means of cleo
trio motors, there Is obtained the adj
ditional advantage of a uniform op-
Grating speed. Another important
consideration is that the element of
personal danger is eliminated With
the switch within ready grasp of the
operator the power can be shut off
instantly at the first sign of danger.
A gasoline electric harvester which
is being used extensively in California
is of interest. 1t consists of an So
horsepower, 6-cylinder gas traction
engine which, in addition to supply
