He rented a farm in Kent, where he depended considerably on rabbiting to make a living. A move to the free-draining chalk downland of Hampshire enabled him to start milking cows using the system developed by Wiltshire dairy farmer Arthur Hosier. The cows were kept out all year and milked in "bails", or mobile milking parlours, which offered a very cheap way of starting up a dairy herd. Paterson started milking with a bail in 1928 (milking the cows himself) and built up a farming empire which came to include up to 10,000 acres (40 km²) (in 1943), and 4,000 dairy cows (in the early 1970s).
