A 5TH COLUMN in YOUR village? Has it occurred to you that all the "old iron" to be found in the cottages, gardens, houses, hedgerows, farms and fields of your village or town represents scores of anti-aircraft shells, several Bren guns, or even a heavy tank? As long as this vital material remains hidden it is as good as a gift to the enemy—it constitutes a veritable Fifth Column. What is more, it means that we have to import more iron ore from abroad—using precious shipping and foreign currency unnecessarily.
