He appeared occasionally as a lecturer, his favorite subject being American humor; and he was able to prove by his scrap-book that he had penetrated as far east as Xenia, Ohio, and as far west as Decatur, Illinois. Once, so ran Fraserville tradition, he had been engaged for the lyceum course at Springfield, Missouri, but his contract had been canceled when it was found that his discourse was unillumined by the stereopticon, that vivifying accessory being just then in high favor in that community. Out of his own reading and reflections Allen had reached the conclusion that Franklin, Emerson, and Lincoln were the greatest Americans. He talked a great deal of Lincoln and of the Civil War, and the soldiers' monument, in its circular plaza in the heart of the city, symbolized for him all heroic things. He would sit on the steps in the gray shadow at night, waiting for Dan to finish some task at his office, and Harwood would find him absorbed, dreaming by the singing, foaming fountains. Allen spoke with a kind of passionate eloquence of This Stupendous Experiment, or This Beautiful Experiment, as he liked to call America. Dan put Walt Whitman into his hands and afterwards regretted it, for Allen developed an attack of acute Whitmania that tried Dan's patience severely. Dan had passed through Whitman at college and emerged safely on the other side. He begged Allen not to call him "camerado" or lift so often the perpendicular hand. He suggested to him that while it might be fine and patriotic to declaim "When lilacs last in the dooryard bloom'd," from the steps of the monument at midnight, the police might take another view of the performance. He began to see, however, that beneath much that was whimsical and sentimental the young fellow was sincerely interested in the trend of things in what, during this Whitman period, he called "these states." Sometimes Allen's remarks on current events struck Harwood by their wisdom: the boy was wholesomely provocative and stimulating. He began to feel that he understood him, and in his own homelessness Allen became a resource.
