That the reader unconsciously recognizes the fact that the essential difference in the office of prose and poetry makes inevitable a difference also of method, is shown by his dissatisfaction when the writer of prose invades the province of poetry. The arrangement of the words of prose into systematic rhythm produces at once an effect of weakness and of insincerity. Dickens in some of his attempts to reach deep pathos has made his prose metrical with results most disastrous. The mood of poetry is so elevated that metrical conventions seem appropriate and natural; whereas in the mood of even the most emotional prose they appear fantastical and affected. The difference is not unlike that between the speaking and the singing voice. A man who sang in conversation, or even in a highly excited oration, would simply make himself ridiculous. In song this manner of using the voice is not only natural but inevitable and delightful. What would be uncalled for in the most exalted moods of the prose writer is natural and fitting in the case of the poet, because the poet is endeavoring to embody, in language the most deep, the most high, the most delicate experiences of which humanity is capable. The form is with him a part of his normal language. To say in prose: "My love is like a red rose newly sprung in June, or like a melody beautifully played," means not much. Yet the words themselves are not widely varied from those in which Burns conveys the same ideas with so great an added beauty, and so much more emotional force:-- Oh, my luve's like a red, red rose That's newly sprung in June; Oh, my luve's like a melodie That's sweetly played in tune. The metrical cadences woo the ear like those of a melody sweetly played, and to that which the words may say or suggest they add an effect yet more potent and delightful. A moment's consideration of these facts enables one to estimate rightly the stricture made by Plato:-- You have often seen what a poor appearance the tales of poets make when stripped of the colors which music puts upon them, and recited in prose. They are like faces which were never really beautiful, but only blooming, and now the bloom of youth has passed away from them. It would be more just and more exact to say that they are like the framework of a palace from which have been stripped the slabs of precious marble which covered it. It is neither more nor less reasonable to object to poetry that its theme told in prose is slight or dull than it would be to scorn St. Peter's because its rafters and ridgepole might not be attractive if they stood out bare against the sky. The form is in poetry as much an integral part as walls and roof and dome, statues and jewel-like marbles, are part of the temple.
