chine, the boxes fastened to the top of
the plates of the box. This shaft had
collars at both ends, with fianges from
which extended four arms to about six
or eight inches from the center of the
shaft, TO which was boiled every alter
nate arm of the wheel. The collars were
fitted to the shafts with keys. As not
every farmer has an old threshing ma
chine to pick to pieces, in most cases
IL would be necessary to devise an
equivalent for its construction, which
any blacksmith can do. The collars
with flanges can be made and shrunk
on 70 any iron on steel shaft One end of
the shaft projects two inches outside
the box and is fitted with crank to
give the length of pump stroke desired
The pump shaft is fitted to this crank
The arms were made by 1laX2 inch fir,
eight feet long and somewhat tapered
to the outer ends. There are eight such
arms at each end of the shaft, thus max
ing 16-foot wheel. No hub is required.
If made square and true at the butts,
the ends accurately chamfered TO n
half inter running TO point, and the

of the shaft, theywill fit exactly around
the shaft and make all the hub required.
In setting up bolt every alternate arm
firmly to the arm of the flange prepared
to receive it. preferred, an eight-arm
flonge may be made, and each arm
bolted. Make an octagon ring of half
inch round iron, or any other iron of
equal strength, with diameter OF
about 40 inches and clamp to each arm.
Beyond that run about three braces of
No. 10 wire entirely round the wheel,
firmly fastening to each arm. Make
the wheels at each end of the shaft eX-
actly alike; fasten thin tough boards
across the arms from one to the other
for about five feet inward from the out
er ends of the wheel: oil the boxes and |
your mill is ready to work. In Mr.. |
Moore's mill the sails are of light duck |
and seem to answer perfectly, but he eX
presses his preference for boards, and |
II similar mill built by one of his neigh
bors had board sails. If metal boxes |
for the shaft to run it cannot readily be !
had the mill will run we'll enough in |
hardwood boxes.
Such a mill will run at all times and |
with a wind from any direction, ex-
cept square across the box. There is |
no way of stopping it without danger of |
injury, and when you need no water |
you must disconnect your pump. or |
course the mill can be stopped, but a
stiif wind would very likely strain the
rather slender construction, if held
rigid, and it needs to be light in order
TO start readily in light breeze.
1t is evident that such a mill as this
con be made to develop great deal of
power by increasing the length of the
arms OF the width of the sails, or both.
The arms should not be less than eight
feet, making a 16-foot wheel, If any
considerable power is expected. The
width of the sails could be widened a
good deal-how much could, perhaps,
only be told by experiment. II is
probable that above u certain width
the wind would C anne over the top of the
box and interfere with the return of the
sails.
The power generated by such wind
mill would always be the difference be-
tween the impact of the wind on the
sails and the resistance of the still air
In the box against their return. An
sx2O foot mill in stiff wind would be
a very powerful engine--quite sufii-
cient to do n good deal of irrigating,
but with wind power reservoir
would be necessary, as water might
he needed when no wind Is blowing.
For ordinary domestic supply such a
mill as we saw certainly supplies '
abundant power, for we saw II doing
the work.-san Francisco Chronicle. II
