The most plaintive of Beethoven scherzos,--that in the Moonlight Sonata, --says as if it were spoken in words: "Once we were happy, now I am forlorn; Fortune has darkened, and happiness gone." Lowell's poetic marriage did not last quite ten years. Maria White was always frail and delicate, and she became more so continually. Longfellow's clear foresight noticed the danger she was in years before her death, which took place in the autumn of 1853. She left one child, Mabel Lowell, slender and pale like herself, and with poetical lines in her face, too, but fortunately endowed with her father's good constitution. Only ten years! But such ten years, worth ten centuries of the life of a girl of fashion, who thinks she is happy because she has everything she wants. If the truth were known we might find that in the twilight of his life Lowell thought more of these ten years with Maria White than of the six years when he was Ambassador to England,--with twenty-nine dinner-parties in the month of June. What would poets do without war? The Trojan war, or some similar conflict, served as the ground-work of Homer's mighty epic; Virgil followed in similar lines; Dante would never have been famous but for the Guelph and Ghibeline struggle. Shakespeare's plays are full of war and fighting; and the wars of Napoleon stimulated Byron, Schiller, and Goethe to the best efforts of their lives. In dealing with men like Emerson, Longfellow, and Lowell, who were the intellectual leaders of their time, it is impossible to escape their influence in the anti-slavery movement, and its influence upon them, unpopular as that subject is at present. That was the heroic age of American history, and the truth concerning it has not yet been written. It was as heroic to the South as to the North, for, as Sumner said, the slaveholders would never have made their desperate attack on the Government of this country if they had not been themselves the slaves of their own social organization. It was the solution of a great historical problem, like that of Constitutional Government _versus_ the Stuarts, and it ought to be treated from a national and not a sectional stand-point. The live men of that time became abolitionists as inevitably as their forefathers became supporters of the Declaration of Independence. If Webster and Everett had been born twenty years later, they must needs have become anti-slavery, too. Those of Lowell's friends, like George S. Hillard and George B. Loring, who for social or political reasons took the opposite side, afterwards found themselves left in the lurch by an adverse public opinion.
