in the 1950's we called them "lost kits"..matches,whistle.
small candle..foil.. so on.. putting the kit together and talking
about what to do to be found again was probably more important
than the kit itself which was more of a "group working together"activity..i recall the "don't call wolf" speech from
the scoutmaster..scouts who hid out for the "fun" of causing
a panicky search for them would be sent home from camp.
