Later life In 1880, two years after resigning from his second term as the president of the Bank of California, Mills returned to New York, where he participated in the development of a number of buildings in Manhattan, including 160 Bleecker Street, or "Mills House No. 1". He also invested in the Niagara Falls Power Company, one of the first large power companies organized in the United States. His devotion to philanthropy involved sitting on the boards of a number of charitable and cultural institutions. He was a trustee of the Carnegie Institution from 1902 to 1909. Millbrae estate Mills bought part of Rancho Buri Buri from José de la Cruz Sánchez and built an estate named Millbrae (also known as the Mill's estate and the Mill's mansion), which gave its name to the present town that grew up around it. The estate took three years to build and was an imposing three-story structure featuring 42 rooms, a conservatory, a carriage house, a gatekeepers house, three artificial lakes, a dairy farm, 37,000 acres of land (at its peak), and various manicured gardens. Due to a large fire, the estate burned down in June 1954. After the fire the estate was subdivided and sold, with the bulk of the land going to the Paul W.
