Problem.

Year after year, as the winter comes
on. the question OF the freezing OF the
cooling water in radiators. vaterjack-
cts, and pumps IS discussed anew
It is a serious matter and g. feature IN
motoring that viii ever have to be dealt

gsrdinE the bursting OF radiators and
wsteriackets from the expansion Of the
freezing water contained therein, This
can be positively prevented by the use
OF anli-freezinE mixtures. OF which
there are a number.
The most widely used and easily OBJ
tanned preparations are calcium chlOr-
