Spain has been the testing ground
for modern weapons of war for two
and a half years. The bomber and
attack plane have taken the acid test.
By means of high flying military air»
planes the civilian population of Loy’
alist Spain has been exposed to fre»
quent air raids, Bombings have not
destroyed the morale of the people
but seemed to strengthen and anger
them against the opposing forces.

No terrific loss of life or great
damage to property has resulted thus
far, in spite of the fact that Madrid
was subject to more air raids in two
weeks then London had through the
entire world war.

The effect of terrorizinu the civilian
populations of the large cities has
worn oil and the people consider the
air raids as just one more unnecessary
and unavoidable evil resulting from
war. In fact pictures have been pub‘
lished in the newspapers and mag-
azines showing residents of Madrid
cuusually going about their business
while enemy bombers fly over head
preparing to drop 500 or 1000 kilo-
gram “eggs."

Anti-aircraft guns make it neces-
sary for the slow flying bombers to
keep an altitude of 15000 feet or
more. Arguments may be presented
pro and con on the efficiency of anti-
aircraft fire, the facts stand that the
bomber still keeps a good bit of atmo-
sphere between the ground and itself.
High altitudes are not highly con-
ducive to accurate bombing“ because
the various air strata may vary in
velocity and direction. That is why
the civilians do not run for shelter as
soon as they see a fleet of enemy
bombers overhead. It is not guaran-
teed that the observer will stay in the
same spot if a bomb lands within a
few feet of him.

Bombing of troops on the march is
a more efficient way to damage the
enemy. Since the large bomber is not
highly manucvcrable and must keep
its distance it is not feared to any
great extent. The type of machine
that puts fear into the hearts of the
ground troops is the dive bomber or
attack plane. Flying at low altitudes
it comes into sight very quickly. The
sudden appearance {rives the man on
the ground very little warning or time
to take any measure of safety. l

The attack plane is a high speed
airplane with extreme flexibility of
control. Standard equipment includes
four 30 or 50 caliber machine guns
mounted at a downward angle of
forty-five degrees in order to spray
ground troops with lead slugs. In the
fusilagc or under the wings is locat-
ed bomb racks capable of holding four
to eight 25 pound demolition bombs.
These bombs explode at the surface
and spray the landscape with steel
for many yards around. This equip-
ment is used by the Loyalists against
Franco. It is highly effective in sur—
prising troop concentrations, causing
a frightful slaughter with a resulting
demoralization which could easily de-
ride a battle.

used. Test tubes hold 60 milliliters,
while centrifuge tubes hold one to
three milliliters. Precipitation is ac«
complished by filtering and evapora—
tion, a long process of sometimes two
or three hours. The centrifuge system
of micro—analysis takes only two or
three minutes at the most.

Semi-micro analysis is, at the pres
out time, standard in only a few col«
leges It was tried out here during
last year’s summer session, and ac~
cording to Dr. Van Atta, chemistry
instructor in charge of laboratory
work, has many advantages over the
old method, macro-analysis. It fea-
tures the minute apparatus, the
small portions of materials, and the
general theory of micro-analysis. The
work is so planned, however, as to
avoid the long, tedious methods of
micro—analysis without appreciably
sacrificing: accuracy.

Introduction of this method is ex—
pected to result in considerable
money saving for both school and
students. The surprising durability
of the minute apparatus eliminates
much breakage, a hazard which form-
ly played havoc with the student
pocketbook. The use of small quan-
tities of chemicals will, of course,

 

save the school much money. 3

Subway Engineers
Award flout-roots
For Second lube

Work on Chicago’s new subway is
progressing rapidly. At present a
pit twenty-five feet in diameter is be~
lhp: excavated on State Street south
of Chicago Avenue. Locks are being-
built for pilot tubes to State street.

The second contract, which involves
the work on Clybourn avenue, has
been let. Out of approximately eleven
contracts for the subway eight will
be let by January of 1940. Two hun~
dred engineers are employed so far.

Some of the most important prob-
lems they have to consider are: pro-
tection of buildings and crossing of
the river at La Salle street. The
street cars run through a tube under
the river on La Salle Street and it is
not definitely known whether the sub-
way engineers plan to tunnel under
the tube or not.

There are surveying parties out
continuously running levels before
and after tunneling in order to de-
termine whether there has been set-
tlement of any building. Some of the
curves which are necessary in order
to get around the larger buildings will
have a large radius of curvature in
order to enable the trains to main-
tain a high speed. Adequate support)
for the elevated along Lake streetl
must also be provided.

Excavation has been proceeding onl
schedule and to date no serious ac-
cidents have occurred.

Annual ERES.
butcher lsleltl In

Beginning with cigars and sound
movies and ending with ice cream
and sandwiches, the Fire Protection
Engineering Society’s annual smok-
or will go down in the annals of the
society as one of the most success-
ful ever held. Under a smoke screen
laid by cigars in the hands of the
45 undergraduates, alumni, and pro«
fessors present, the first reel of a
two reel show was flashed on the
south wall of the main lounge in the
new student union.

The Educational Film Company,
in conjunction with the Veneer As-
sociation, presented “Forest Treas-
urc," a story of the veneer industry.
It is one of the few modern indus—
tries which must depend upon primi-
tive methods for its supply of rare
woods, which come from the inlands
of Africa, Australia. India, and the
Americas. Like the arms of a huge
devil fish, this United States indus-
try rcaches into all parts of the
world, bringing back rare woods,

.such as mahogany, sycamore, zebra

wood, luee wood, olive wood, satin
wood, walnut, and American oak.

These "diamonds in the rough" arc
barked and treated in a 190" F.
steam bath from one to four days.
After this bath they are moist and
pliable enough to be sliced into
vecncr 1/28 of an inch thick. After
these slices have been dried, they are
trimmed and squared. Skilled work-
men then piece these slices together
in the many beautiful and intricate

patterns found in furniture and
homes today.

These veneers are also used as
facing; for plywood, giving the effect
of solid pieces with the advantages
of economy, equal strength in all di-
rections, resistance to shock and
splitting, counteraction to expansion,
and the possibility of manufacturing
any size sheet demanded.

The art of veneer is by no means
a new one. The only existing; pieces
of woodwork done by the ancient
Egyptians, 3500 years ago, are
veneered. Hundreds of years later,
Chippendale, I‘Ieppelwhite, and Shera-
ton, of England; and Duncan-Phyl'e
of America, took advantage of this
practice when they made the beauti-
ful antique furniture so highly
valued today. At present, 90 per“
cent of our furniture is veneered and
precious woods are within the budg—
ets of everyone.

The second reel was on the com-
edy side, showing, three shorts of
Popeye. Popeye, with the aid of his
faithful can of spinach, fought his
way out of three extremely precar-
ious predicaments in as many min-
utes.

Following this, Professor Finne»
gun presented the Crosby-Fishe-
Forster Handbook of Fire Protection
to Robert H. Harmon. This “bible”
of the fire protection engineer is pre-
sented each year by Salamander,
honorary fire protection fraternity,
to the present sophomore who made
the best scholastic record as a fresh—
man. Its purpose is to promote good
study habits among students enter-
ing the department, and results
proved that it accomplishes its pur-

pose.

The work and pleasure of the eve«
ning then being- finished, the smoker
was adjourned at 10 o’clock.

W Show General

[M otors Movies
At Assembly

“Color Harmony", a sound motion
picture in full color, was one of the
films presented at the first general
assembly of the semester, in the school
auditorium, last Friday afternoon at
10:30. The pictures, which were
shown by Mr. Randegger of the Gen-
eral Motors Corporation, demonstrat—
ed the mechanism of an eye and ex-
plained the functions of the cones and
rods of the retina, the sensitive por-
tion of the eye. These cones contain
chemicals which are sensitive to one
of the primary colors.

When a beam of colored light strik—
es the cones, an electric current is set
up which flashes a signal to the brain
causing the sensation of color. The
eye is capable of blending these im-
pulses and registering the different
color combinations and shades. The
application of a pleasing combination
of color shades to the modern motor
car was then demonstrated.

Another picture entitled “Vacuum
Control” explained the operation of
various devices actuated by differ-
ences in air pressures. Soda straws,
airplane wings and rubber suction
cups were shown as examples of this
phenomenon. The development of a
new development in gear shifting was
then shown. With no radical changes
in the transmission, a system of lev-
ers operated by a lever on the steer-
ing wheel post replaces the conven-
tional controls. However, 80 per cent

 

of the shifting effort is furnished by
l a vacuum plunger operating from the
l intake manifold.
