factor OF prime importance in
the development Of transportation
over the highways IS the trailer.

Rubber Co. and its use and i'm

economical has the trailer proven
IN many lines of haulage that every
operator OF motor trucks should
carefully analyze his delivery ia

business men everywhere are realiz-

is sound.

Dispose OF Horses.
Regular horse-drawn wagons were
used TO collect the garbase from

siguated place. here the horses
were unhitched and the loaded
wagons attached to a 5-ton truck
A load OF four and one aalf tons
of scrap iron was placed IN the truck
body IN order 10 give traction to the
driving wheels. The ROAD travelled
passed under viaducts. around sharp
turns and up steep grades The TO p
tai LOAD including the weight OF
The trailers was y tons. The test
covered a round trip distance of
e21z miles and resulting in the city

more than half of the horses pre-

This case is not exceptional In
Detroit a dealer IN crushed stone
hauis 90 tons regularly with one
truck. IN Los Angeles recently Il

load over "a distance of IS miles;
in an Indiana town a two-ton truck

The trailer uses the surplus power
% the trucks engine which would
be Otherwise wasted. In addition TO
carrying capacity every truck has
drawbar pulling power. If the
motor truck operator is not availing
i himself OF the latent power Of his
truck ne is neglecting a factor which
might reduce his transportation re-
uuircments by zoe or 300 per cent.
Road Conditions Factor.
MOTOR truck operators must bear
in mind. points out the Goodrich
co, the amount load which g

depends upon the conditions of the
road and grade met with. Foe il.
