Hawthorne are the product of a truly imaginative intellect, restrained, and in some measure repressed, by fastidiousness of taste, by constitutional melancholy and by indolence. But it is of his tales that we desire principally to speak. The tale proper, in our opinion, affords unquestionably the fairest field for the exercise of the loftiest talent, which can be afforded by the wide domains of mere prose. Were we bidden to say how the highest genius could be most advantageously employed for the best display of its own powers, we should answer, without hesitation—in the composition of a rhymed poem, not to exceed in length what might be perused in an hour. Within this limit alone can the highest order of true poetry exist. We need only here say, upon this topic, that, in almost all classes of composition, the unity of effect or impression is a point of the greatest importance. It is clear, moreover, that this unity cannot be thoroughly preserved in productions whose perusal cannot be completed at one sitting. We may continue the reading of a prose composition, from the very nature of prose itself, much longer than we can persevere, to any good purpose, in the perusal of a poem. This latter, if truly fulfilling the demands of the poetic sentiment, induces an exaltation of the soul which cannot be long sustained. All high excitements are necessarily transient. Thus a long poem is a paradox. And, without unity of impression, the deepest effects cannot be brought about. Epics were the offspring of an imperfect sense of Art, and their reign is no more. A poem _too_ brief may produce a vivid, but never an intense or enduring impression. Without a certain continuity of effort—without a certain duration or repetition of purpose—the soul is never deeply moved. There must be the dropping of the water upon the rock. De Béranger has wrought brilliant things—pungent and spirit-stirring—but, like all immassive bodies, they lack _momentum_, and thus fail to satisfy the Poetic Sentiment. They sparkle and excite, but, from want of continuity, fail deeply to impress. Extreme brevity will degenerate into epigrammatism; but the sin of extreme length is even more unpardonable. _In medio tutissimus ibis._
