In 1921, Fr.Gavan Duffy started a Training School at Tindivanam with 22 students. St.Anne’s Primary school became a Middle School under the effective direction of Bro.Claudien (Montfort Brother).
More than schools and teachers, Fr.Gavan Duffy was interested in the training of the Catechists. The training given by Fr.Gavan Duffy would prepare Teachers or Catechists with good formation in Secular and religious studies. The best teachers after a few years of teaching would be raised to the grade of Catechists.
Archbishop Morel, 68 years old, requested Rome to accept his resignation, which was accepted. Fr.Colas was appointed and was consecrated by Archbishop Morel on 29th September 1930. Retiring to Yercaud, Mgr.Morel did what he could do for about ten years. In 1940 he went to St.Martha’s Hospital, Bangalore and he died there in 1948, eighteen years after his resignation.
