the myriad sounds and intonations of the spoken English language in their writing. He called his colloquial approach to language "the sound of sense". In 1924, he won the first of four Pulitzer Prizes for the book New Hampshire: A Poem with Notes and Grace Notes. He would win additional Pulitzers for Collected Poems in 1931, A Further Range in 1937, and A Witness Tree in 1943. For forty-two years – from 1921 to 1962 – Frost spent almost every summer and fall teaching at the Bread Loaf School of English of Middlebury College, at its mountain campus at Ripton, Vermont. He is credited with being a major influence upon the development of the school and its writing programs. The college now owns and maintains his former Ripton farmstead, a National Historic Landmark, near the Bread Loaf campus. In 1921, Frost accepted a fellowship teaching post at the University of Michigan, Ann Arbor, where he resided until 1927, when he returned to teach at Amherst. While teaching at the University of Michigan, he was awarded a lifetime appointment at the university as a Fellow in Letters. The Robert Frost Ann Arbor home was purchased by The Henry Ford Museum in Dearborn, Michigan, and relocated to the museum's Greenfield Village site for public tours. Throughout the 1920s, Frost also lived in his colonial-era house in Shaftsbury, Vermont. In 2002, the house was opened to the public as the Robert Frost Stone House Museum in 2002 and was given to Bennington College in 2017. In 1934, Frost began to spend winter months in Florida. In March 1935, he gave a talk at the University of Miami. In 1940, he bought a plot in South Miami, Florida, naming it Pencil Pines; he spent his winters there for the rest of his life. In her memoir about Frost's time in Florida, Helen Muir writes, "Frost had called his five acres Pencil Pines because he said he had never made a penny from anything that did not involve the use of a pencil." His properties also included a house on Brewster Street in Cambridge, Massachusetts. Harvard's 1965 alumni directory notes that that Frost received an honorary degree there. Although he never graduated from college, Frost received over 40 honorary degrees, including from Princeton, Oxford and Cambridge universities, and became the only person to have received two honorary degrees from Dartmouth College. During his lifetime, the
