$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
48 consecutive hours, 100 bushels of it being fine meal. I have also
ground 24 full bushels of fine meal for table use in two hours. This
last was my own, consequently was not tolled. This was before I bought
the iron mill, and now I can nearly double that amount. I saw my fire
wood for three fires; all my fence posts, etc. My wood is taken to the
mill from 12 to 15 feet long, and as large as the saw will cut by
turning the stick, consequently the saw requires about the same power as
the burrs. With a good sailing breeze I have all the power I need, and
can run all the machinery with ease. Last winter I ground double the
amount of any water mill in this vicinity. I have no better property
