Boston's Cure For Truancy

School principáis in Boston are not much troubled by truancy in their schools. Every morning, directly after the opening of the school, every principal nalees out a list of the names and addresses of the pupils who are absent without known cause and hands it to the policeman on the beat. It then becomes the business of this functionary to cali at the addressea given and ascertain the causê of absence, liy this system unexcused absences are very few. No youngster is going to dodge his arithmetic and geography when he knows perfectly well that before dinner time a big policeman will cali at his father's house to know why he is not at school.
