During a visit in 1885 English journalist George Augustus Henry Sala coined the phrase "Marvellous Melbourne", which stuck long into the twentieth century and is still used today by Melburnians. Growing building activity culminated in a "land boom" which, in 1888, reached a peak of speculative development fuelled by consumer confidence and escalating land value. As a result of the boom, large commercial buildings, coffee palaces, terrace housing and palatial mansions proliferated in the city. The establishment of a hydraulic facility in 1887 allowed for the local manufacture of elevators, resulting in the first construction of high-rise buildings; most notably the APA Building, amongst the world's tallest commercial buildings upon completion in 1889. This period also saw the expansion of a major radial rail-based transport network.
In what year was a hydraulic facility established?
A: 1887

Over 50% of undergraduate students live on campus. Most of the residence halls on campus are located on the South 40, named because of its adjacent location on the south side of the Danforth Campus and its size of 40 acres (160,000 m2). It is the location of all the freshman buildings as well as several upperclassman buildings, which are set up in the traditional residential college system. All of the residential halls are co-ed. The South 40 is organized as a pedestrian-friendly environment wherein residences surround a central recreational lawn known as the Swamp. Bear's Den (the largest dining hall on campus), the Habif Health and Wellness Center (Student Health Services), the Residential Life Office, University Police Headquarters, various student-owned businesses (e.g. the laundry service, Wash U Wash), and the baseball, softball, and intramural fields are also located on the South 40.
