cepted by the general rules committee OF
! twenty-five Of the representative manu-
/ facturers and importers before being
/ passed on to the contest board OF the
/ American Automobile Association for in

tC place upon the American Automobile AS
sociatton the responsibility for this portion
OF the rules.
