I do not mean to imply that there is more poetry in the prose writings of a nation's literature than in its verse writings. The prose writer usually travels leisurely and waxes ecstatic occasionally. He does not concentrate his emotions nor seek to depict them immediately. The verse writer as a rule tries to depict emotions from the start. He is greater as a poet than many prose writers, because he poetizes, thinking he must do this naturally in verse, while the prose writer does not believe it is his duty to do so in prose, but he is often a poet because he cannot help it. There is more poetry in a volume of Burns or Shelley or Heine than in a volume of similar length by a prose writer, because these poets tried to put emotion into every separate portion, no matter how small. Yet a prose writer can do the same thing if he wants to do so.
Any one who is a great reader of books of travel is impressed by the fact that in these works there is occasionally literature of ecstasy of a high order. There are descriptions and narratives recorded with beauty, vividness, interest; there are reflections, insight into human nature that often surpass the works of prose fiction and verse poetry we read. Yet because these works are called "travels," they are not supposed to contain poems or creative literature. Had the authors given us as good description in verse, the critics would have called them poets.
Hearn's books on Japan are after all works of travel, but they contain poetry or the literature of ecstasy because Hearn was a poet. I am not claiming for many works of travel a place only as literature, for it is usually conceded that the best books of travel are literature, but I urge that many of these books are in parts poetry, and their authors are poets. It is recognized, however, that Pierre Loti is a poet in his books of travel. Doughty's _Arabia Deserta_ is full of poetry.
_Robinson Crusoe_ and _Gulliver's Travels_ are but works of travel, and are poetry because of the ecstatic presentation of ideas. You will find poems in prose not only in the travels of great writers, like Goethe, Taine, Heine, in the works of old writers who were chiefly travelers, like Hakluyt, Mandeville, Marco Polo, but in many volumes that have been published in our own day.
