To be brief and compendious on this book, it appears to be a heart unveiled. German critics throw some doubts on the literal veracity of the book; but it belongs at any rate to the better class of the _ben trovati_, and among its leaves, the dreamer, the lover, and the poet will find that ambrosial fruit on which fancy loves to feed, but whose blossoms are so generally blasted by the common air that only the few favored ones have had their longings for it appeased. In imagination, at least, Bettina partook of this banquet, and had the genius to wreak on words the emotions which swept through her heart. _Sir Rohan's Ghost._ A Romance. Boston: J. E. Tilton & Company. 1860. pp. 352. It is very plain that we have got a new poet,--a tremendous responsibility both for him who will have to learn how to carry the brimming vase of Art from the Pierian spring without squandering a drop, and for us critics who are to reconcile ourselves to what is new in him, and to hold him strictly to that apprenticeship to the old which is the condition of mastery at last. Criticism in America has reached something like the state of the old Continental currency. There is no honest relation between the promises we make and the specie basis of meaning they profess to represent. "The most extraordinary book of the age" is published every week; "genius" springs up like mullein, wherever the soil is thin enough; the yearly catch of "weird imagination," "thrilling pathos," "splendid description," and "sublime imagery" does not fall short of an ordinary mackerel-crop; and "profound originality" is so plenty that one not in the secret would be apt to take it for commonplace. Now Tithonus, whom, as the oldest inhabitant, we have engaged to oversee the criticism of the "Atlantic," has a prodigiously long memory,--almost as long as one of Dickens's descriptive passages,--he remembers perfectly well all the promising young fellows from Orpheus down, and has made a notch on the stalk of a devil's-apron for every one who ever came to anything that was of more consequence to the world than to himself. His tally has not yet mounted to a baker's dozen. Accordingly, when a young enthusiast rushes to tell Tithonus that a surprising genius has turned up, that venerable and cautious being either puts his hand behind his ear and absconds into an extemporary deafness, or says dryly, "American kind, I suppose?" This coolness of our wary senior is infectious, and we confess ourselves so far disenchanted by it, that, when we go into a library, the lettering on the backs of nine-tenths of the volumes contrives to shape itself into a laconic _Hic jacet_.
