his marriage to Sarah Simpson, daughter of A. M. Simpson, who settled on her the whole of his considerable stake in the company. With the inexorable expansion of Adelaide's suburbs, the land was sold to developers. The olive crushing plant was actually in what is now the suburb of Wattle Park, at the western end of Crompton Drive. In August 1932, the Stonyfell Olive Company was the largest producer of olive oil in South Australia, and it entered into an agreement with Bickford's (manufacturers of drinks and cordials) to do the bottling of the oil. Chiverton Another grand manor, Chiverton, was built in the Italianate style in 1880 for merchant John Nankivell, but he soon afterwards leased the house to Harry Bickford, the manufacturer of drinks, cordials and syrups. The house was purchased by the Anglican Community of Sisters in 1894, who established a school on the premises. In 1957 the Sisters moved their North Adelaide school, St Peter's Girls' School, to the Stonyfell building. The house, stables and coach house were made of stone from the nearby quarry, and are now heritage-listed. The house is used as the school's administration building Description Stonyfell Creek arises on the eastern border of Stonyfell, flowing through several suburbs before joining Second Creek. St Peter's Girls' School was founded in 1894 in North Adelaide and moved to its current site on Hallett Road in Stonyfell in 1957. The cellars of the old Stonyfell winery now house Massey wines, while Stonyfell Wines now uses vineyards at Langhorne Creek. There is still a quarry operating at Stonyfell , operated by Boral since the 1980s and extracting sandstone and quartzite. The Stonyfell Quarry Reserve is on Penfold Road. Parks and reserves The Ferguson Conservation Park, adjacent to St Peter's School, was dedicated as a conservation park on 2 June 1977. It is a Category III protected area. In 1980, the conservation park was listed on the former Register of the National Estate. The Michael Perry Botanic Reserve, comprising a long strip of land along Second Creek, originally part of the Clifton Manor estate, was created in the 1970s. It is named after Michael Perry, who was a councillor, alderman and Mayor of Burnside between 1958 and 1983. A Vegetation Management Plan for the reserve was published by the council in 2012, which recommended a return to the native vegetation of the area. Restoration work has been
