Chicago. On the car It weighed 23,0O0
pounds. Inserted in the bottom was a
short steel shaft two inches in diameter.
To this was to be attached a weight to
sink the box. The box was shipped TO
Chicago and preparations were made to
test the machine of that city, but since
the chart showed a maximum depth of
seventy feet Milwaukee was chosen.
In the Beer City preparations for test
ing the Schon bell were completed by MIR.
Lutz, Schon and Samuel Harper, Mr..
Lutz's representative. Floating and tow
ing equipment was secured, and a prelim-
mary test was decided upon. The scien-
lists said that one could not remain under
water in that space longer than fifty TO
sixty minutes. They figured that 216
cubic feet of air would be consumed in
that time, but SchOn, when he went down
in il for a test. stayed three hours,
smoked. burned matches and watched sew
age from the city float past him, and
then only came up because he was tired
staying down.
With this point settled, the more i'm
portant one, whether or not the vessel
could withstand the pressure of deep wa
ter, was the concern of the friends of the
box. They estimated that at 200 feet,
each side Of the box would be subjected
TO pressure of $4,000 pounds. The actual
pressure at that depth is less. But since
the weight could not be piled on each Of
the four sides and two ends at the same
time the test could not be made above
ground Bat, so sure was Mr.. Schon that
the machine was strong enough, he want
ed TO go down for the practical test. He
was persuaded to wait for the second
trip.
Finally all arrangements were compile
ted and with the bell on a big scow, and
a steam holster in the fleet, tug hauled
the explorers seward.
The chart showed that the bed Of the
lake at Milwaukee inclined gradually
from the shore, and when the tug had
travelled nearly twelve miles the depth
of water was considerably more than 200
feet. A pressure gauge made for the pur-

the chains attached TO the end was a
scantling projecting several feet TO either
side. Ropes were fastened to this to pre-
vent the cage from swinging or twisting,
Inside two stringers, eight by six inches,
were fixed across the box just below the
windows to add to the strength of the
heavy metal sides and assist in coping
with the pressure under the water A
long distance telephone was also put in
To the steel bar in the bottom was at
tached $500 pounds of metal, but this was
found insufficient to sink it, and 100
pounds of chain were added.
Then the word was given, and the en-
gineer allowed the big bronze box to pass
from view A brief stop, was made to
the result was a showing of 500 pounds
Here was a hollow cube of six feet weigh
reduced to 500 pounds submerged. indicat-
ing that the weight of water displaced
was 5000 pounds, or thirteen tons.
Again the thing was started bottom
ward Each of the ropes attached to the
scantling was marked at intervals of
twenty-five feet as a check on the depth
reached Down, down, it went, but it
was not very long before some one saw
the telephone come speechless to the sur
face. 1t did not need to be heralded; ev-
erybody saw it and knew what it meant
| Then, as if all the settler and soda water
bottling tanks in the national asSoeia-
tion had been let loose, the water com
menced to effervesce and sparkle and
presently a great hubble of air burst and
all was over. The word TO hoist away
was given, and the Inflated box was
brought to view again.
One of the heavy oak tinlbers was driven
into itself and splntered to matchwood.
! The inch-thick plate glass was almost
puverized. Mr.. Harper says that accord
| ing to the ropes, the machine was down
/ 200 feet, but the gauge showed a pressure
/ of SO pounds, which, if it registered cor
rectly, indicated a depth of 22S feet. But
| on a basis of 200 feet the pressure that
crushed this seemingly invulnerable phos-
| phOr-bronZe structure was $3.50 pounds per
| square inch, or 353,924 pounds to each
side of six feet square. The total pres
sure therefore, was 2,723,54S pounds. or l.
1t seems incredible that with the ex-
! traordnary strength of the bell it should
be sol crushed. With contrivance that
would Withstand the pressure of deep
water Ut was Mr.. Schon's intention to
| use it m locating wrecks, and afterward,
! by the use of the telephone, to direct the
| work of Nwreckers on the surface, either
| in graphing for cargo or in placing light
! er chains about the hulls of vessels.
In the ordinary diving dress divers sell
1 dom work Yin more than 100 feet of wa
| ter. at which depth the pressure is As. 4
! pounds perl square inch. 1t has been
| claimed that diver attempted to de-
scend to the wreck of the Elbe, the At
| iantic liner that lies in the English Chan
! mel in 240 feeL of water. He was brought
! up almost unconscious from 10 feet
/ where the pressure was 73.7S pounds per
| square inch, a pressure that few can ex-
perience and live.
/ j. Schneider of this city, a hydraulic en-
| gineer of wide reputation, says apparatus
| can be constructed that will do the work
! intended for the Schon machine. He sug-
| gested, when consulted, that it be made
| either in the form of sphere or an
/ elipse, for the reason that the pressure
cannot get the same action as with a
/ cube, and that the shape he suggests will
| withstand a. much greater pressure than
! the cube form.
| He also suggests that, instead of large
| barred windows, a glass having magnify
| ing power could be used that would pene-
| trate the water a greater distance than
| the eye unasssted. This glass could
work in a swivel, to enable it to sweep
| large field.
