Madam, – Your letters (July 3rd and 4th ) refer to the poor condition of our national flag displayed on certain buildings at home and abroad . One could also lament the obvious ignorance of etiquette in the treatment of this emblem. The national flag should be set to fly above other flags and lowered at dusk. Most of our displays seem to be in permanent positions. Perhaps a lesson in basic civics would help sustain our national pride . – Yours, etc,
