The following text, comprising of advice and musings from famed American poet Walt Whitman, was adapted from a series of 1858 newspaper columns he wrote under the pseudonym Mose Velsor. The columns—entitled “Manly Health and Training, with Off-Hand Hints Towards Their Conditions”—ran in the relatively obscure paper The New York Atlas, and were unknown to be penned by Whitman for over 150 years. The 47,000-word series was published after the first two editions of Whitman’s famed Leaves of Grass had debuted to little fanfare, and before the landmark 1860 edition was published.
