Fruits, vegetables, beef and dairy cattle, mules, sheep, pigs, chickens, turkeys, pheasants and brook trout were raised on the farm.
In addition to the 800 regularly employed workers Miner hired around 100 families to camp at Flat Rock and pick berries.
Miner also built a 20-bedroom guesthouse and an entertainment center named Harmony Hall, which included an auditorium, complete with a stage large enough for 300 people.
Miner's will established the school and farm, The William H. Miner Agricultural Research Institute, a private, not-for-profit educational research institution with an operational dairy farm and Morgan horse herd located in Chazy, New York on the Adirondack Coast of Lake Champlain.
Created in 1951, the Institute’s mission is to offer quality research, education, and demonstration programs addressing critical agricultural and environmental issues relevant to Northern New York, Vermont and Quebec farmers.
