burned no bearings before our error was discovered and so learned a
valuable lesson more cheaply than we deserved.

Keeping the radiator protected against freezing is not complicated.
Nearly any filling station has the necessary hydrometer. To be sure
the anti-freeze liquid has not evaporated unduly, have the radiator
contents tested about once in two weeks, particularly after several
days of abnormally warm weather. For real safety, it is wise to have
any automobile radiator filled with enough of the compound so that its
freezing point is fully ten degrees colder than the lowest temperature
expected. There are two reasons for this margin. It allows for a
slight percentage of evaporation and for a certain peculiarity of
country highways. There are sometimes points on the road where, for
some reason, the actual temperature is a full five degrees colder than
elsewhere. We have seen many cars steaming and boiling in such places.
We have once or twice been in the same unhappy situation and know that
thawing a radiator so frozen is slow work, requiring blankets and
plenty of patience.

A word as to the clothing especially designed for the cold of the
country. Wool-lined mittens may seem to hark back to sleighbells and
buffalo robes, but driving a spirited span hitched to a cutter was a
summer occupation compared to steering an unheated automobile ten
miles on a below zero morning with ordinary gloves. Mittens are not
graceful but in them the fingers are not confined and therefore do not
chill as quickly.

Further, do not scorn the good old-fashioned arctics. Get the high
four-buckle kind. They afford real protection against cold and snow
and a pair lasts for several years, particularly in the sections of
the country where snow and abnormally cold weather are intermittent.
Sweaters and woolen mufflers should also be part of the added
equipment, for nothing makes for such misery as getting thoroughly
chilled for lack of adequate outside clothing. A walk or a drive
becomes then just an endurance test.

We have one last warning. The mitten and overshoe theory may seem to
you but a sad sign of approaching age and debility--and so none of
them for you. Granted they are not needed except for abnormal weather,
some bitter cold evening you may arrive home with fingers, or ears, or
toes frostbitten. Don't under such circumstances go into a warm roo
