Such is the nature of the poem, which does undeniably exhibit many proofs of genius, accomplishments, power of expression, and learning; but which, nevertheless, we cannot accept as a great work. It is like an ornament in which some gems of the purest lustre are set, side by side with fragments of coloured glass, and even inferior substances. The evident presence of the latter sometimes shakes our faith in the absolute value of the jewels, which are deserving of better association; and we cannot help wishing that the whole work could be taken to pieces, the counterfeit materials thrown aside, and the remainder entirely reconstructed on a new principle and design. There is ever an intimate connection between the design and the material. Thoughts, however rich in themselves, lose their effect when ill displayed; and the want of the knowledge of this has ere now proved fatal to the fame of many a promising artist. The language and sentiments of Elsie, however beautiful in themselves--and that they are beautiful we most unhesitatingly maintain--excite in our minds no sympathy. They are simply portions of an ill-constructed drama, almost aimless in purpose, and without even an intelligible moral; they do not tend to any point upon which our interest or expectations are concentrated, and therefore, in order to do justice to them, we are forced to regard them as fragmentary. Mr Longfellow has not succeeded in giving a human interest to his drama. His story is poor, or rather incomprehensible, and his plan essentially vicious; and these are faults which no brilliancy of execution can ever serve to redeem. We are deeply disappointed to find that such is the case, for we can assure the author that we have watched his poetical career with no common interest--that we have long been aware of the great extent of his powers--and that we have waited, with much anxiety, in the expectation of seeing those powers exhibited in their full measure. We fear that we must wait a little longer before he shall do justice to himself. It is a sound rule in criticism that every work is to be judged according to its profession; an epic as an epic--a drama as a drama--a ballad as a ballad. After making every allowance for the avowed irregularity of this composition, we cannot admit that it satisfies even the requirements of a dramatic romance. It cannot be said that it was purposely constructed to exclude belief, and therefore, interest; because Mr Longfellow has taken obvious pains to mark the time by the accessories, in which he has perfectly succeeded; and also to give us a vivid sketch of society as it then existed. His radical error, we think, may be traced to two things--the want of a life-like plot, and the introduction of supernatural machinery.
