The higher the
line from whence
the water falls,
the greater the
momentum acquired
by means
of a given quantity
of water.
The utmosttotal height
to which water is
capable to be pre
raised by the pressure
of the atmosphere
is never
less than 33 foot
Suppose each
1. Each flash
exprells out half
the air
2. Three foot is
the rise required
to be given by
each stroke
Let them
1. The cover be
33 high from the
surface of the water
in the pond
2. The lowest line
of the discharging
mouth or mouths
27 foot

Thence the water
being already at
27 a flash will
raise it to 30
foot, and so toties
quoties.
N.B. It may be
easily drawn up
to that height &
kept there, by the
means that will
be mentioned presently.
Drawing the water
up to this height
before the machine
begins to work has
two good effects
1. It makes the
fall be from the
greatest height
possible.
2. By lessening
the height and
consequentlythence the
bulk of the flash
-chamber, it makes)
a given quantity
- of fuel go so
much the farther.
