We have before us one of the most extraordinary specimens of Yankee intelligence and American eccentricity in authorship, it is possible to conceive. It is of a genus so peculiar as to embarrass us, and has an air at once so novel, so audacious, and so strange as to verge upon absurdity, and yet it would be an injustice to pronounce it so, as the work is saved from this extreme by a certain mastery over diction not very easy of definition. What Emerson has pronounced to be good must not be lightly treated, and before we pronounce upon the merits of this performance it is but right to examine them. We have, then, a series of pithy prose sentences strung together—forming twelve grand divisions in all, but which, having a rude rhythmical cadence about them admit of the designation poetical being applied. They are destitute of rhyme, measure of feet, and the like, every condition under which poetry is generally understood to exist being absent; but in their strength of expression, their fervor, hearty wholesomeness, their originality, mannerism, and freshness, one finds in them a singular harmony and flow, as if by reading, they gradually formed themselves into melody, and adopted characteristics peculiar and appropriate to themselves alone. If, however, some sentences be fine, there are others altogether laughable; nevertheless, in the bare strength, the unhesitating frankness of a man who "believes in the flesh and the appetites," and who dares to call simplest things by their plainest names, conveying also a large sense of the beautiful, and with an emphasis which gives a clearer conception of what manly modesty really is than any thing we have, in all conventional forms of word, deed, or act so far known of, that we rid ourselves, little by little, of the strangeness with which we greet this bluff new-comer, and, beginning to understand him better, appreciate him in proportion as he becomes more known. He will soon make his way into the confidence of his readers, and his poems in time will become a pregnant text-book, out of which quotation as sterling as the minted gold will be taken and applied to every form and phase of the "inner" or the "outer" life; and we express our pleasure in making the acquaintance of Walt Whitman, hoping to know more of him in time to come.
