rk. On the farm where it is used, there are
raised annually an average of sixty acres of oats, fifty acres of corn,
twenty acres of rye, ten acres of buckwheat.
Bushels.
The oats average, say 30 bushels per acre. 1,800
Corn " 30 " " 1,500
Rye " 20 " " 400
Buckwheat " 20 " " 200
Grinding for self and others. 1,000
It will cost to thrash this grain, shell the corn, and
grind the feed with steam power. $285
And sawing wood, 121/2 cords. 18
Pumping, one hour per day, 365 days. 36
Churning, half hour per day, 200 days. 10
Washing, half day per week, 26 days. 26

Total. $375
This amount is saved, and more too, as one man, by the aid of the wind
mill, will do this work in connection with the chores of the farm, and
save enough in utilizing foul weather to more than offset his extra
labor, cost of oil, etc., for the machinery. The amount saved each year
is just about equal to the cost of a good man. Cost of outfit,
$700--just about equal to the cost of a good man for two years,
consequently, it will pay for itself in two years. Fifteen years is a
fair estimate for the lifetime of mill with ordinary repairs.
The solid-wheel wind mill has never been built larger than 30 feet in
diameter. For mills larger than this, the latest improved American mill
is the "Warwick" pattern.
A 30-foot mill of this pattern, erected in 1880, in northwestern Iowa,
gave the following results, as reported by the owner:
"Attachments as follows: One 22-inch burr; one No. 4 iron feed-mill; one
26-inch circular saw; one two-hole corn-sheller; one grain elevater; a
bolting apparatus for fine meal, buckwheat and graham, all of which are
run at the same time in good winds, except the saw or the iron mill;
they being run from the same pulley can run but one at a time. With all
attached and working up to their full capacity, the sails are often
thrown out of the wind by the governors, which shows an immense power.
The machines are so arranged that I can attach all or separately,
according to the wind. With the burr alone I have ground 500 bushels in
