the twelve buildings constructed in 1891, the most prominent are two of the four double officers' quarters (Bldgs 6 and 7) which front the old parade ground. Other buildings constructed in 1891 included a 60-man barracks, a commissary storehouse (Bldg 10), a quartermaster storehouse (Bldg 11), a granary (Bldg 12), a bakery (Bldg 24), a stable (Bldg 25) and the first two of four non-commissioned officers' (NCO) quarters (Bldgs 30 and 33). These NCO quarters became known as "soap-suds row' because many of the NCO wives were former army laundresses who supplemented their husbands' income by doing laundry for post personnel. 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." Construction during this period also included two double officers' quarters (Bldgs 4 and 5) which completed "officers' row" in 1893. Two NCO quarters (Bldgs 31 and 32) were added to "soap-suds row" in 1897 and the distinctive cavalry barracks (Bldg 27), which now houses administrative offices, was constructed in 1899. Captain Hiram M. Chittenden was the U.S. Army Corps of Engineers senior engineer in Yellowstone from 1899–1906. The Corps had been responsible for road and other infrastructure construction within the park since 1883. In 1901,
