There Is a slight gain in the us;
of battery ignition, which is to be TX
pected, but, as. heretofore, 1t appear.
on the smaller capacity trucks whic.
are generally equipped with elect:i
lighting and starting. Approximasc
ly % per cent OF the models are mag

manual control is employed.
Relative to the battery ignition

The use of electrical equipment has
Increased slightly on ali trucks

'apacity and less have electrical
equipment as standard and about o.
per cent of the lh-ton. The use of
starters or electric lighting 10 slightly
increasing on the I and S ton models
and a number Of makers give option
Of starting and lighting.
Average Horsepower.
In the matter Of horsepower
ratings. the average horsepower
that about 50 per cent Of the models
pacity and under Is 1854, against
l6.92, there being a slight decrease
In the bore. The average horsepowe
of the 1.ton models Is 1851, against
$3.50. That of the 11s-ton remains
practically the same. as do the 2, az
and 5, but there is an increase in the
average horsepower of the c-ton, it
being 27.20, against $3.50.
Dealing with methods Of circulat-
ing the cooling fluid, 1t will be found
ing methods. Governors controlling
Of 1 4 ton and under have the thermo

practically universal on the larger
capacity trucks. The cellular type
OF radiator is employed on the lighter
types with the fin on the larger, and
inc use OF cast cases predcminates
where the FIN core is used. The use

As to clutches. the dry disc or n,,ts
