3. Another consideration, though it will not so much interest young men, will cheer the heart of older scholars, namely, that there is diurnal and secular rest. As there is this daily renovation of sensibility, so it sometimes, if rarely, happens that after a season of decay or eclipse, darkening months or years, the faculties revive to their fullest force. One of the best facts I know in metaphysical science is Niebuhr's joyful record that, after his genius for interpreting history had failed him for several years, this divination returned to him. As this rejoiced me, so does Herbert's poem "The Flower." His health had broken down early, he had lost his muse, and in this poem he says:-- "And now in age I bud again, After so many deaths I live and write; I once more smell the dew and rain, And relish versing: O my only light, It cannot be That I am he On whom thy tempests fell all night." His poem called "The Forerunners" also has supreme interest. I understand "The Harbingers" to refer to the signs of age and decay which he detects in himself, not only in his constitution, but in his fancy and his facility and grace in writing verse; and he signalizes his delight in this skill, and his pain that the Herricks, Lovelaces, and Marlows, or whoever else, should use the like genius in language to sensual purpose, and consoles himself that his own faith and the divine life in him remain to him unchanged, unharmed. 4. The power of the will is sometimes sublime; and what is will for, if it cannot help us in emergencies? Seneca says of an almost fatal sickness that befell him, "The thought of my father, who could not have sustained such a blow as my death, restrained me; I commanded myself to live." Goethe said to Eckermann, "I work more easily when the barometer is high than when it is low. Since I know this, I endeavor, when the barometer is low, to counteract the injurious effect by greater exertion, and my attempt is successful." "To the persevering mortal the blessed immortals are swift." Yes, for they know how to give you in one moment the solution of the riddle you have pondered for months. "Had I not lived with Mirabeau," says Dumont, "I never should have known all that can be done in one day, or, rather, in an interval of twelve hours. A day to him was of more value than a week or a month to others. To-morrow to him was not the same impostor as to most others."
