came to live with him at Yarralumla homestead. Augustus Gibbes improved the estate and acquired additional land by purchase and lease. In 1881, he sold Yarralumla for 40,000 pounds to Frederick Campbell, a descendant of Robert Campbell, to travel overseas. Frederick Campbell erected a new, three-storey, brick house on the site of the former Yarralumla homestead at the beginning of the 1890s. Campbell's house would later form the basis of what is now the Governor-General of Australia's official Canberra residence, known colloquially as "Yarralumla" or "Government House". Campbell also built the large wooden Yarralumla Woolshed nearby in 1904. In 1908, the Limestone Plains area, including Yarralumla, was selected as the site for the capital city of the newly established Commonwealth of Australia and in 1913 the Commonwealth Government purchased the property. Tenant farmers were allowed to stay on the land on annual leases, some remaining until 1963 when the Molonglo River was dammed to form Lake Burley Griffin. Development With the construction of Australia's capital city underway, the Yarralumla brickworks were established in 1913 to supply building material. The bricks were used for many of Canberra's buildings, including the provisional Parliament House. The Brickworks tramway, a 3 ft 6 in (1,067 mm) goods railway, was constructed for the transportation of bricks to some of the major building sites in central Canberra. This linked the brickworks to places such as Parliament House, and the Kingston Power House. Construction on the Commonwealth nursery and Westbourne Woods arboretum was started in 1914, and a temporary camp was built near the brickworks to accommodate the workers. Thomas Charles Weston was Officer-in-Charge (Afforestation Branch) in the years 1913 to 1926, and later became Director of City Planting and the Superintendent of Parks and Gardens. Weston was responsible for testing and selecting plant species at the arboretum for their suitability to Canberra's environment; from 1913 through to 1924 Weston oversaw the propagation of more than two million trees which were then planted in the Canberra area. Most of the original Westbourne Woods arboretum is now leased to the Royal Canberra Golf Club, with the remainder forming part of Weston Park. The Yarralumla nursery is still active, albeit on a smaller scale and functioning as a retail nursery selling both wholesale and direct to the public. In 1917, the designer of Canberra, Walter Burley Griffin, named the area surrounding the brickworks "Westridge". It was part of the
