To Longfellow he wrote, June 6, 1842:—
It is artillery election-day, and the streets are full of happy throngs, and the Common is blackened by the multitude. . . . I received to-day an invitation from the Phi Beta Kappa Society of Dartmouth College to deliver the oration before the Alpha. Of course, I must decline. . . . How I envy Felton's happiness! His own bosom is such an overflowing fountain of goodness as to supply perpetual sources of happiness, which diffuse their refreshing influences over all about him, like the cool and abundant waters of the Fountain of Trevi at Rome.
