Just a reminder. The Castleton Historical Society will host 'Schoolhouse Slates', a program on America's early school slate industry which began right here in the Slate Valley. Dale and Joan Prouty are longtime area educators and museum programmers. Their program includes examples of creative student slate improvements designed for young scholars during the mid-19th through mid-20th century. We will meet at the Castleton Community Center, just east of Castleton Corners on Wednesday, June 21st at 6 PM. Refreshments. There is no charge for this handicapped accessible program. Questions? Call Holly Hitchcock at 468-5105.
