they reach the top, or get well off from the
ground, they explode. That brings coo:-
ness.
The windmill structures are erected in this
shape for beauty. The picturesque eie
ment OF the Cross arms, the little structure
and their grace are the reasons this form
is selected. It's economy is another. a
i framework of wood is cheaper than tower
of wood. And. OF course, cheaper than
stone. To make these wi ndm ills still
prettier, there are vines planted around
them, and the windmill and its arms can he
covered with verdure in Summer when they
are in operation. In winter they can be
taken down and stored away until next
season.
The important element Of the windmill
cooling apparatus Is the bomb. This is
an immense affair filled with carbonic
acid gas i'll a liQuefied state. The gas is
put under powerful pressure until it
liquefies. 1t is then pressed INTO the bomb
shape.
The machinery of the cooling apparatus
consists Of electric wires, besides the car
bonic acid bombs. These wires are run
by power, SO that they carry the, bombs
along quickly to the top OF the tower,
Once there. they come under powerful
electric shock and are exploded.

face of the earth, 1t is not a good sub
stance to work with in this state. But
the fact that it is heavier than common
air and settles low is the principle upon
which the explosive works.

this evaporation the atmosphere around is
severely chilled and the c;irbonic acid gas,

The scheme of, carrying it out is pro
posed for whole cities. A string of towers
or windmills with wires attached to them
would have to- be built around the town
and the bombs operated from them on q
hot day. Its expense is considerable and
so it is likely that none but model towns
will try it right away. Fol-. q place like

of machinery could be made ornamental

There are other equally interes ting
schetnes for Keeping cool. One OF these
is the odd but sensible one Of fitting re.

could be done at small expense, but il

the fan is stopped and removed.
An ideal way OF operating the fan is
to place 1t behind lattice WORK. One
end of the room could be covered witii
