Werribee :
Fr. de la Peza has been recalled to Montreal. When the hour of his departure arrived a very large contingent of the students gathered on the railway platform. With them were all the available Fathers of Corpus Christi and representatives of other houses. Fr. de la Peza was evidently moved at the kindness shown to him. A rousing three cheers accompanied the moving off of the train.
At Sydney there were other demonstrations of farewell, particularly an entertainment given by the Rector of Riverview, in which the Apostolic Delegate and other representative clerics took part, and in which complimentary speeches were made referring to the departing Father's success as a preacher, professor, and giver of clerical retreats.
