flash. To be
if it be deemed advisable
to raise
the water be by successive
flashes before
it is let out then
the strength must
be accordingsufficient for to a
greater height of
water
Quere which is best?
to work with single
flashes, or successive
flashes?
By a single flash y
ou get say 16
foot rise of water
By 2 flashes you
get 24 feet of water.
Quere which has
most power? one
cylinder of 24 foot
altitude: or 2 cylinders
of the same
diameter, each of
16 foot altitude.

As the more water
the greater more of
the caloric is wasted
in forming steam
with it, the power
of the Machine
depends absolutely
upon the driness of
the match: therefore
1. There It will be
worth while to make & keep
it dry in the Match-
Chamber or the
Exsiccation place
2. No moist fuel
nothing of oil or turpentine
should be
employ'd.
Air changing Machine
The Winnowing machine
may be made
to move by wind while
there is any - the
machinery requisite
will be very little
The wind alone without
the Windmill
would not do, since
it would neither move
always in the proper
direction, nor fast
enough.
Could any thinguse
be made of the force
acquired by the burnt air
from its expulsion ".
Hardly - since it
would not act. but
in proportion as it was
in a state of compression,
nor would it be
kept in a state of compression,
but at the
expence of the ventilation power.
