Rh though a positive merit of the highest class, demands in its attainment less of invention than negation.

Of course, I pretend to no originality in either the rhythm or metre of the "Raven." The former is trochaic—the latter is octameter acatalectic, alternating with heptameter catalectic repeated in the refrain of the fifth verse, and terminating with tetrameter catalectic. Less pedantically—the feet employed throughout (trochees) consist of a long syllable followed by a short: the first line of the stanza consists of eight of these feet—the second of seven and a half (in effect two-thirds)—the third of eight—the fourth of seven and a half—the fifth the same—the sixth three and a half. Now, each of these lines, taken individually, has been employed before, and what originality the "Raven" has, is in their combination into stanza; nothing even remotely approaching this combination has ever been attempted. The effect of this originality of combination is aided by other unusual, and some altogether novel effects, arising from an extension of the application of the principles of rhyme and alliteration.

The next point to be considered was the mode of bringing together the lover and the Raven—and the first branch of this consideration was the locale. For this the most natural suggestion might seem to be a forest, or the fields—but it has always appeared to me that a close circumscription of space is absolutely necessary to the effect of insulated incident:—it has the force of a frame to a picture. It has an indisputable moral power in keeping concentrated the attention, and, of course, must not be confounded with mere unity of place.
