4 We are not unaware, Venerable Brothers, of all that has been done by every one of you for the establishment and the success of schools and academies for the proper education of children. By your zeal in this respect you have clearly acted in conformity with the exhortations of the Apostolic See and the prescriptions of the Council of Baltimore. Your magnificent work on behalf of the ecclesiastical seminaries has assuredly been calculated to increase the prospects of good to be done by the clergy and to add to their dignity. Nor is this all. You have wisely taken measures to enlighten dissidents and to draw them to the truth by appointing learned and worthy members of the clergy to go about from district to district to address them in public in familiar style in churches and other buildings, and to solve the difficulties that may be advanced. An excellent plan, and one which We know has already borne abundant fruit. Nor has your charity been unmindful of the sad lot of the negro and the Indian - you have sent them teachers, helped them liberally, and you are most zealously providing for their eternal salvation. We are glad to add a stimulus, if such be necessary, to enable you to continue these undertakings with full confidence that your work is worthy of commendation.
