 Around the same time, he established the Briarcliff Table Water Company and the Briarcliff Greenhouses. The water company sold its products in five cities, and owned 250-foot (76 m) wells. Briarcliff Farms was one of the first producers of certified milk in the U.S., and the farm produced about 4,500 US quarts (4,300 litres) of milk daily. Every night, his milk, cream, butter and kumyss was sent to New York City on the New York and Putnam Railroad. Law's greenhouse space grew to 75,000 square feet (7,000 m2), and his roses earned up to $ 100,000 each year. As many as 8,000 roses were shipped from Briarcliff Greenhouses daily, most of them to New York City. In 1902, Law built the Briarcliff Lodge on the highest point of his estate; it was the first hotel in Westchester County.
