Radiator Care.
Small radiator leaks, only
minor annoyance in Summer,
when the cooling system contains
nothing but water, should be
carefully attended to before the
cooling system is Serviced with
anti-freeze for cold weather driv-
ing. While water costs nothing
beyond the trouble and time nee
essary for pouring it into the
radiator, the loss of anti-freeze
solutions is expensive and may re-
suit in frozen motor.
Recent tests have proved that
the most frequent cause of radia-
tor leaks is mechanical breakage
due to joltS and constant vibra-
ton. This cause is common to all
cars and the results accumulate,
of course, at the end of the Sum-
mer. The second most prolific
cause of leaks is corroSion of the
metal tubes or channels, of which
the radiator is composed. One OF
the interesting discoveries in re-
gard to radiator deteriorations is
| that this corroSion may progress
more rapidly in Summer, when
the cooling system contains water
only, and is definitely checked by
certain anti-freeze solutions.
| Drivers of motor cars who at
this time of the year are plan
ming to put their automobiles in
good condition for the Winter
should remember five things:
Five Aids Given.
1. Careful research investiga-
tions by chemists, extending over
many months, have disclosed that
the accumulation of foreign sub
stances in the radiator is in di-
rect ratio to the mileage driven
and is but little affected by the
age of the car.
2. Rust formed by the action OF
water and air on iron and steel
parts, together with grease from
the water pump, tends to settle in
| the water passages of the engine
block and form a heat insulative

ing. Such a condition is not par
ticularly serious, but when small
portions of this coating become
dislodged and are carried by the
flow of the cooling water into the
small passages of the radiator core
a badly clogged radiator soon re-
suits.
8. Stoppsge of the radiator
passages affects the operation OF
a car in a number of ways. The
motor overheatS, and, at best, can
be driven at only small fraction
of its maximum speed. Gasoline
consumption is higher, and, in ag-
gravated cases, the cylinder walls
become scored.
4. A successful radiator cleaner
must be able to attack grease and
scum and to loosen scale and rust
particles quickly and easily, and
still be safe for the average car
owner to use. In addition, 1t
should operate while the car is in
normal use. Care should be taken
to select one that does not injure
the hose or metal parts.
S. Radiator cleaner should be
used in the Fall before filling with
anti-freeze solution and in the
Spring after its removal. 1t should
also be used when the radiator
water gets dirty and rusty, and
when the engine shows signs of
overheating.
Answering statements attributed
to railroad executives that there
is chaos in highway transport OF
freight, E. F. LOOMS of the
National Automobile Chamber Of
Commerce, speaking at the
twelfth annual meeting of the
American Petroleum Institute in
Chicago last Wednesday, declared
that this statement is based on
the assumption that trucking may
grow into great consolidated Sys-
TENS comparable with our rail-
roads.
II think this premise is false"
said Mi. LOOMS. There are def
mite reasons why the truck should
be in the main plant facility, as
it is today, rather than unit in a
transportation system.
Freight Transportation.
Trucks have been in use in
considerable numbers for 20 years,
and in wide use for 10 years, and
there is no appreciate trend to-
ward consolidation except in
the regular-route, common carrier
branch of the business, and there
a more pronounced movement to-
ward larger operating units may
be expected. This branch of the
business apparently is not gaining
proportionately at the expense of
the rest"
Mr.. LOOMS, using Government
traffic surveys, declared that 80
per cent of our trucks are owned
by shippers who carry their own
goods; IL per cent by truckers un-
der contract arrangements with
shippers and per cent by agree
ments with those in the business
OF catering to the miscellaneous
needs of many shippers. Only 2
per cent Of all trucks are in COM
mon-carrier truck lines over regu-
lar routes comparable to railroad
service.
other surveys indicate that
there are 100000 owners of
trucks, all but 100000 of whom
own only one truck each. The
other 100000 owners account for
about 100000 trucks. The aver
age number of trucks to each
owner is, therefore. less than one
I and one-half.
1t is the application of this in
dividuality of freight transport
within limited areas, comparable
