Never, we claim, will the missionary potentialities that lie dormant in Canadian Catholicism, be actuated to bear its message of spiritual light, heat and power to the Church at large, until we establish in the field at various points, secretaries or organizers, whose life-work will be to call into play, to systematize the mission forces of the Church in Canada. If on the contrary, as in the past, we content ourselves with an occasional appeal for missions, a collection now and then, a spasmodic effort here and there, a subscription to a Catholic paper or missionary magazine, the work for Home and Foreign missions will remain exterior to the corporate life of the Church, will not be woven into its very fibre to permeate its activities. As shadows on the wall, they will suggest rather than reveal the possibilities of our missionary effort. The great and pressing call of the White Shepherd of the Vatican will go unheard. If there is a response that comes from Canada, it will not be from the Church at large. _II.--What?_ The "_raison d'etre_," the definite function of a field-secretary is organization. This work implies the double duty to spread, by an intelligent and well thought-out propaganda, the knowledge of the Home and Foreign Missions and of the responsibility it entails, and to found and maintain efficient the various societies established to promote and help their great work. 1. _Vision_. The effective presentation of the case of Catholic Missions, both to the clergy and to the laity, is the field-secretary's first and important duty. Nothing indeed can be hoped for, nothing can be accomplished until the Catholic people fully grasp and intensely feel what their help and co-operation--however little it may be--mean to the Church, to the salvation of souls, to the honour of our Blessed Lord, to the glory of God. _Fac ut videant_! The clear, broad and deep vision of these great possibilities in the mission fields will alone overcome selfishness and apathy, awaken interest, stimulate energy. The field-secretary is the official expert in mission-matters. He will be able to accumulate strong evidence, sum up striking statistics and draw burning comparisons for the effective presentation of his case. An enthusiastic advocate, he will plead with thrilling appeals, the great cause placed in his hands. During his absence from the field of action, the vision he pointed to, will be kept bright by the recurrence, at stated intervals, of the printed message. Missionary literature receives its life, vigour and impulse from the field-organizer and continues his work in his absence.
