His attention slowly shifted away from "The Midwife" when he wrote for, and won, the "Seatonian Prize" for his "On the Immensity of the Supreme Being" and when he began working with Newbery's children's magazine, "The Lilliputian Magazine". However, Smart returned to this character full force when he established "The Old Woman's Oratory; or Henley in Petticoats" in December 1751. The "Oratory" included Smart playing as Mrs. Midnight, various songs and dances, animal acts, and "miscellany" acts. The "Oratory" was successful, and was completely redone on 21 January 1752. However, not everyone enjoyed the show, and Horace Walpole described the performance as "the lowest buffoonery in the world even to me who am used to my uncle Horace." Late in 1752, Smart finished and published a collection of his works as "Poems on Several Occasions", which resulted in the end of the "Oratory" and "The Midwife".
