Longfellow was the next eldest of the truly great poets. In the pages of the _United States Review_ in the twenties some of his earliest poems are found side by side with Bryant’s. In later life he acknowledged to Bryant how much he owed the latter: “When I look back upon my early years, I cannot but smile to see how much in them is really yours. It was an involuntary imitation, which I most readily confess.” Bryant was interested in his career long before he had published a volume of verse, and took care in the _Evening Post_ to give his first two books, the prose “Outre Mer” (1835) and “Hyperion” (1839) due praise. Of the former he said that it “is very gracefully written, the style is delightful, the descriptions are graphic, and the sketches of character have often an agreeable vein of quiet humor.” The latter was treated a little less warmly. The romance is “tinged with peculiarities derived from the author’s fondness for German literature,” Bryant wrote, and its strain of deeper reflection “now and then passes into the grand dimness of German speculation.” The story was slight, and had little attraction for those who wished a narrative of crowded incident. But the verdict as a whole was favorable: “upon the slender thread of his narrative the author has hung a tissue of agreeable sketches of the different parts of Germany, supposed to be visited by the hero, delineations of character, and reflections upon morals and literature.” The _Evening Post’s_ review of Longfellow’s first volume of poems, “Voices of the Night” (1839; signed J. Q. D.) was short but flattering. It quoted the purest poetry of the little book: I heard the trailing garments of the night Sweep through her marble halls! and its criticism emphasized the two youthful qualities which should have been most emphasized, simplicity and freshness. “These voices of the night breathe a sweet and gentle music, such as befits the time when the moon is up, and all the air is clear, and soft, and still. The original poems in the volume are characterized by the truest simplicity of thought and style; the thin veil of mysticism which is thrown over some of them adds only grace to the picture, without tantalizing the eye.” Longfellow’s second volume, the “Poems on Slavery” (1842), came as a shock to a society as yet not inured to anti-slavery doctrines. The editors of _Graham’s Magazine_ wrote the author that the word “slavery” was never allowed to appear in a Philadelphia magazine, and that the publisher objected to have even the title of the book mentioned in his pages. Till a later date Harper’s in New York similarly objected to mention of the slavery question. But Bryant quoted “The Slave’s Dream” in full, and said of the sheaf: “They have all the characteristics of Longfellow’s later poems, adding to the grace and harmony of his earlier, a vein of deeper and stronger feeling, maturer thought, bolder imagery, and a more suggestive manner.”
