President Caldwell preached the baccalaureate sermon for the Class of 1885, drawing his text from Proverbs, xxxvii.17: “Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.”  “A strong intellect,” he told the class, “may go with a heavy heart.  It is the liveliness of our disposition, the hearty sympathy we have with other people, the hearty zest we have in our employments, the spirit we put into whatever we do, that makes life go easy or hard.”     The New York Times
