After leaving the mercantile business in Frederick County, Thaddeus Bussard turned to farming in Montgomery County, where land was more plentiful and inexpensive. When the Bussard family bought this property in 1888, only a horse shed stood on it, but by 1906 Thaddeus had added a smokehouse, blacksmith shop, hen house and brooder, ice house, carriage house, double cornhouse, granary, wind break, hay barrack, and a large bank barn. He maintained a crop rotation of corn every third or fourth year, followed by grasses, wheat, wheat and clover together, and then hay, and stored corn in an elevated double corn crib. Over time, as on many farms, the corn crib was replaced by a silo. Thaddeus and Ann Bussard deeded the property in 1924 to their second son, Harry, who had begun running the farm in 1916 when he married Catherine Lawson. They raised nine children in the house, and the family contributed to the farm economy through chores such as collecting eggs and milking cows, while Thaddeus marketed the farm’s products by rising at four o’clock in the morning, loading a wagon, and traveling down 7th Street Pike to markets in Washington. The farm covered 270 acres until it was conveyed to M-NCPPC in 1971. Established in 1977, the Agricultural History Farm Park teaches Montgomery County’s agrarian practices from 1776 to World War II.
