A number of significant buildings were added to the fort from 1893 to 1899 including a 10-bed hospital, quarters for hospital personnel (Bldg 14), and a large hay shed (Bldg 20) which were constructed in areas behind officers' row in 1894. Of these structures, only the hospital quarters building remains and is now used as a private residence. The most significant building constructed in 1895 was the U.S. Commissioner's office, which included a jail and residence for the U.S. Marshal (Bldg 49). The first commissioner was Judge John W. Meldrum who served the army and National Park Service until 1935 from this building. Located well west of the rest of the fort, this was the first stone building within the fort. It was a one-and-a-half-story rock-faced sandstone dwelling with gable-on-hip roof, through-the-cornice dormers and a full-width porch. The ground floor of the house contained the jail, office, and living quarters while bedrooms were situated on the second floor. The structure is used today as a private residence. The building was funded with the passage of the Lacey Act of 1894. Sponsored by U.S. Representative John F. Lacey, the Lacey Act was ""An Act To protect the birds and animals in Yellowstone National Park, and to punish crimes in said park, and for other purposes.""
