The Self-Master Colony (1908–1938) was an approximately 
30 year experiment in housing the homeless in Union Township, Union County, New Jersey. A lengthy article about it was published in the December 9, 1911 issue of Literary Digest magazine.
The colony was built on the Hoyt family mansion and founded by Andress Small Floyd and his wife Lillian. Some 100,000 men stayed there over a span of approximately 30 years. When financial markets fell in 1929, Floyd was among the victims. The Township bought the property in 1938 for $57,000.
