or the bubble representing the excess OF
pressure on the bottom of the globule over
the pressure on top, which causes the bubble
to rise and gives 1t velocity. Theoretically
the bubble would have the same velocity
whether under one foot or 100 feet Of water,
its velocity being the same as that acquired
by a body falling through space OF the d.
ameter Of the bubble. Therefore the veiocity
Of a bubble arising through water increases
in the inverse ratio Of squares of the dame
ter, or a bubble of air will rise eight feet
per second, one foot in diameter, in the open
water. In a tube the water must pass
around the bubble at the same velocity as
maintained by the bubble itself, taking up a
large portion of the tube in consequence, the
remaining cross section being left for the
flow of the water, consequently when your
bubble is nearly or quite as large as the tube
1t will act as a piston and natures force Is
seen working for the betterment Of mans
condition.
Mr.. Priestly, however, not content with
the forces as he finds them, has inserted a
four-inch pipe into the large pipe through
which air passes and which, falling upon the
column of water in the long arm of the
U-shaped pipe, adds materially to the dis
placement of the water which by aid Of the
separator is constantly going on.
CAPACITY OF THE PLANT.
This novel and ingenious plant, which
shows every reason for success, coupling as
it does with all the laws of mechanics, ac-
cording to the young inventor, will dis
charge in the neighborhood of Is ,000, 900 gal
Ions of water per day and this geyser-like
pump will continue to raise water on the
bench lands above the Snake river until
some of the stationary parts rust or wear
away or the supply of water is cut off.
To put these great pipes in place, rivet
them together at riveting stations along the
face of the wall rock, was no ordinary tri-
umph of engineering in itself, the danger at
tendant upon the lowering of the immense
steel columns being very great, and even
with the utmost care Priestly came very near
yielding up his life the other day, a sacri-
flee to his remarkable invention. He was
standing on a scaffold at an elevation OF
about fifty feet when one Of the aprons blew
out, the force carrying him off the platform,
hurting him twenty-five feet. striking the
front of a rock rounded by water and covered
with moss, which broke the force of his fall.
He was carried into his tent overlooking the
work, where he has, been confined for several
days. The absence Of the guiding spirit In
the new enterprise stopped all work. but
Priestly is again at his post and 1t is possible
that by the time this letter appears In The
Bee the weary months of hard labor which
w. w. Priestly has given to the solution OF
the carrying power and velocity of bubbles
will be rewarded beyond his most sanguine
expectations.
THE INVENTOR.
Mr.. Prlestly is a tall, angular man, Of un.
certain age, He may be 40. yet hardly looks
80. He is an enthusiast upon this growing
| question Of irrigation and came from the
University Of Kansas to take a position with
the Boston G. Butte Mining company as q
mining engineer five or six years ago. He
enjoys the confidence of his employers, whC
are conservative business men, and ! coma,
IDENTIFY believe their judgment in him will bt
more than justified when the great pump al
the Thousand Springs commences its worl
for the greater Idaho.
While the element OF uncertainty plays nc
small part In the success OF the pump al
these springs, 1t was one Of the great pleas
