The first poem known to have been published in this measure was Blood-Money, which appeared in Horace Greeleys Tribune (Supplement), 22 March, 1850. But Isle of La Belle Rivière, published in the Cincinnati Post, 30 April, 1892, was written, in what is now called imagist verse, at the age of thirty (184950), while New Years Day, 1848, written in an album just before Whitmans departure for New Orleans, shows a tendency to break away from conventional forms. By far more important are the Harned manuscript notebook specimens already mentioned.
