 The Artillery continued to occupy a social niche in Lyndeborough into the early twentieth century.Its annual levee and ball began to feature oyster stew as one of its featured dinners, and even in the 1930s—when Lyndeborough's population was only 399 people—the ball often attracted 400 people or more to South Lyndeborough.The group's centennial in September, 1904 was, essentially, a February 22 celebration, though lunch and most of the orations during the day were held outdoors at the home of Artillery captain Andy Holt.
