SHAFTSBURY -- The "Sunday Afternoons with Robert Frost" series, held each summer at the Robert Frost Stone House Museum, will start at 2 p.m. Sunday, June 8, when Frost scholar David Sanders returns with a program he calls "Frost's Lyric Constellations: ‘Mending Wall,' ‘After Apple Picking,' and ‘The Wood Pile. ‘"

Sanders will show how these three poems reflect the changes that were taking place in the traditional culture and economy of the New England that Frost knew and loved. Between them, these poems hold the structure of Frost's second published collection, "North of Boston."

Celebrating three signature tasks of spring, fall, and winter, they reveal a retreat in the face of a growing capital economy.

Sanders, professor emeritus at St. John Fisher College in Rochester N.Y., holds degrees from Brown University and Cornell University, and is the author of "A Divided Poet: Robert Frost, ‘North of Boston' and the Drama of Disappearance."

The programs in the "Sunday Afternoons with Robert Frost" series are sponsored by the Friends of Robert Frost and are free.

The Robert Frost Stone House Museum at 121 Vermont Route 7A in South Shaftsbury is open 10 a.m. to 5 p.m.Wednesday to Sunday. For more information, call (802) 447-6200 or visit frostfriends.org.
