"Compare | to Columbian | Mag. I, 36"
Note 15 says that the poem appeared in New York's Columbian Lady's and Gentleman's Magazine of January 1844. The note in green ink in the upper left margin of the first photocopied page says to "Compare to Columbian Mag" and the manuscript note titling the photocopy clearly indicates "The Rover, vol. II, 1844." The manuscript note in blue ink on the blank third image also says: "Seba Smith's poem in Rover."
