31 Because of Our constant desire that scientific progress in all its branches be ever more universally affirmed, We gladly take this opportune occasion to signify to you Our cordial interest in the University at Washington. You remember well with what ardent wishes Pope Leo XIII greeted this noble temple of learning when it came into being and on how many occasions testimonies of particular affection were bestowed upon it by Our immediate predecessor. He was intimately persuaded that if this great school, however blessed already with success, should become still stronger and gain even greater renown, not only would the growth of the Church be aided but also the civil glory and prosperity of your fellow citizens.
