It appears evident, then, that there is a distinct limit, as regards length, to all works of literary art--the limit of a single sitting--and that, although in certain classes of prose composition, such as _Robinson Crusoe_, (demanding no unity,) this limit may be advantageously overpassed, it can never properly be overpassed in a poem. Within this limit, the extent of a poem may be made to bear mathematical relation to its merit--in other words, to the excitement or elevation--again in other words, to the degree of the true poetical effect which it is capable of inducing; for it is clear that the brevity must be in direct ratio of the intensity of the intended effect:--this, with one proviso--that a certain degree of duration is absolutely requisite for the production of any effect at all. Holding in view these considerations, as well as that degree of excitement which I deemed not above the popular, while not below the critical, taste, I reached at once what I conceived the proper _length_ for my intended poem--a length of about one hundred lines. It is, in fact, a hundred and eight. My next thought concerned the choice of an impression, or effect, to be conveyed: and here I may as well observe that, throughout the construction, I kept steadily in view the design of rendering the work _universally_ appreciable. I should be carried too far out of my immediate topic were I to demonstrate a point upon which I have repeatedly insisted, and which, with the poetical, stands not in the slightest need of demonstration--the point, I mean, that Beauty is the sole legitimate province of the poem. A few words, however, in elucidation of my real meaning, which some of my friends have evinced a disposition to misrepresent. That pleasure which is at once the most intense, the most elevating, and the most pure, is, I believe, found in the contemplation of the beautiful. When, indeed, men speak of Beauty, they mean, precisely, not a quality, as is supposed, but an effect--they refer, in short, just to that intense and pure elevation of _soul_--_not_ of intellect, or of heart--upon which I have commented, and which is experienced in consequence of contemplating "the beautiful." Now I designate Beauty as the province of the poem, merely because it is an obvious rule of Art that effects should be made to spring from direct causes--that objects should be attained through means best adapted for their attainment--no one as yet having been weak enough to deny that the peculiar elevation alluded to is _most readily_ attained in the poem. Now the object, Truth, or the satisfaction of the intellect, and the object Passion, or the excitement of the heart, are, although attainable, to a certain extent, in poetry, far more readily attainable in prose. Truth, in fact, demands a precision, and Passion, a _homeliness_ (the truly passionate will comprehend me) which are absolutely antagonistic to that Beauty which, I maintain, is the
