Introduction. This and the previous poem in the collections of 1645 and 1673 ("On the University Carrier") are Milton's contributions to the Hobson jest poems popular on campus at Cambridge University after the death of Thomas Hobson on January 1, 1631. Hobson was eighty-six when he died and he had served the university for over sixty years by driving a regular coach between The Bull, a London inn, and the University, carrying students, guests, letters, and sometimes parents. He also hired out horses. The expression "Hobson's choice" originated as a sarcastic reference to Hobson's insistence that anyone hiring a horse must "choose" the one closest to the stable door.

Milton's second Hobson poem, "Another on the same," appeared with another Hobson poem, called "Hobsons Epitaph," in a collection called A Banquet of Jests. Or A Collection of Court. Camp. Colledge. Citie, Country Iests (London 1640) pages 129-132. A 1657 edition of much the same book, now called A Banquet of Jests New and Old Or Change of Cheare (London, 1657) printed both poems again with some changes on pages 82-84. Milton's first Hobson poem was republished along with the others as "Another" in Wit Restor'd In severall Select Poems Not formerly publish't (London 1658) pages 83-84. These are all collections of jokes, ribald stories, and satires based on stereotypes of women, servingmen, lawyers, clerics, and others. The unattributed Hobson poem that appears in all the collections mentioned above may also, suggested W. R. Parker (Modern Language Review 31 [1936]: 395-402), be Milton's, though Milton never chose to include it in either the 1645 or 1673 collections. The copytext for the present edition is 1645.
