On Saturday September 28, 2019

Event Time 10:00 am - 11:30 am

Sermons in Stone is the enthralling story of the stone walls that are everywhere in New England. It is a story that.begins in the Ice Age and that has been shaped by the fencing dilemmas of the nineteenth century, by conflicts between Native Americans and colonists over land use and by American waves of immigration and suburbanization. In this surprising and illuminating talk Susan Allport will illustrate how these walls are much more than monuments to the skill of Yankee farmers.

Susan Allport is a science writer turned baker whose books have focused on the world around her. Her book, Sermons in Stone: The Stone Walls of New England and New York has been praised as a “well-written, fascinating contribution to the region’s social and economic history”

Less expensive and much more delightful than florist flowers to decorate your house! Page will show you how she has been forcing bulbs for years and she will share her favorite ones.

Page Dickey is a garden writer, lecturer and designer. She serves on the board of directors of the Garden Conservancy where she co-founded the Open Days program in 1995.
