where the sugar cane was grown. Hill also supported the work of the Queensland Acclimatisation Society which was formed in 1862, and the Botanic Gardens was the propagation and distribution point for the Society's imports. The first jacaranda tree in Australia was planted at the Botanic Gardens in 1864. A curator collected seedlings from an international ship docked in the Brisbane River. The cultural popularity of the jacaranda across Brisbane City was subsequently spawned. By 1866 Hill had succeeded in having the extent of the Botanic Gardens enlarged to approximately . A strip along Alice Street was not part of the Gardens but served as a park and sporting field known as Queen's Park. Early building work in the area included a Superintendent's cottage in the late 1850s, a platform for a battery of cannon in the early 1860s, a stone and iron fence around Queen's Park in 1865–66 [utilising stone from the old gaol on Petrie Terrace], and a drinking fountain in 1867. The fountain, designed by Colonial Architect Charles Tiffin, was erected only a year after reticulated water from the Enoggera reservoir was introduced to Brisbane. It later became known as the Walter Hill fountain. A row of figs were planted in the 1870s. Hill also planted avenues of Bunya pines and Cook pines. Scientific activity was complemented by public recreational use of the Gardens, along with the Domain (on the southern boundary of the Gardens) and Queen's Park. By the 1880s, some of the scientific work previously performed by the Botanic Gardens was being carried out by the Queensland Acclimatisation Society at Bowen Park. The Herbarium and Botanic Library were moved from the Gardens for a period but were returned in 1905 when John Frederick Bailey was appointed Curator of the Botanic Gardens. Underground electricity supply was installed in 1907. Extensive dredging of Gardens Point in 1915 removed about from the Domain (the southern side of Gardens Point) and Botanic Gardens but in the following year the amalgamation of the Gardens, Queens Park and part of the Domain resulted in a new Botanic Gardens of about . The extant City Botanic Gardens was formed by the amalgamation of the original Botanic Gardens with the Domain (the southern side of Gardens Point) and Queen's Park in 1916, bringing its total area to around ; Queen's Park comprised a strip along Alice Street, which originally served as a park
