SMOOTH OPERATION
IS AN ESSENTIAL
Comfort and Silence Are Quail

Automobile.
VERY DIFFICULT TO OBTAIN

BLING OF PARTS.

If a vote were taken among all the
automobile owners in America to dis
cover what qualities are most to be
desired in an automobile ii is safe to
say that the majority would vote for
comfort and silence. These qualities,
most difficult for the manufacturer TO
attain, may be said TO emDOdy all other
features Of the car, and If we take
comfort 10 mean freedom from worry

why it would not be more profitable
TO build more cars and assemble the

the experienced manufacturer, OF

maintenance of a high standard or qual-
