Question: In what year was Sproat Lake renamed Sproat Lake? Passage 1:Born in Brighouse Farm Borgue near Kirkcudbright, Scotland, he arrived on Vancouver Island in 1860, where he helped to found the first sawmill in Port Alberni, British Columbia. On 24 July. 1863 he was made a justice of the peace for the Colony of Vancouver Island. When the sawmill burnt down in 1865, Sproat returned to England, but maintained his interest in the affairs of the colony, which was united with the mainland in 1866. Sproat's fascination with the First Nations people he encountered on Vancouver Island, led to his best remembered book, The Nootka:Scenes and studies of savage life, which appeared in 1868. In 1870 he wrote Education of the Rural Poor which argued for the extension of elementary education to all, including agricultural laborers. Following British Columbia's entry into Canadian Confederation in 1871, Sproat became the new province's agent general in London, a position he held from 1872 until his return to the province in 1876. Beginning in 1883, Sproat began travelling to the Interior of British Columbia, especially to the Kootenay region, where he held several regional offices. After 1898, Sproat returned to Victoria, where he spent the majority of his time writing. He died there on 4 June 1913. Sproat Lake and Sproat Lake Provincial Park on Vancouver Island are named in his honour by Robert Brown.
 Passage 2:On October 11, 1949, United States Secretary of State Dean Acheson appointed Gross as the United States' deputy delegate to the United Nations. Only two months later, the chief delegate, Warren Austin, took a leave of absence, and Gross took over as acting head of the U.S. delegation to the U.N. The major issue facing the United Nations at that time was the Soviet Union's proposal that, with the conclusion of the Chinese Civil War, the Communist People's Republic of China should replace the Republic of China on the United Nations Security Council. On January 13, 1950, the Soviet delegate, Jacov Malik, walked out of the Security Council in protest. Malik remained absent for several months, and as such the Soviet Union failed to exercise its veto power to block United Nations Security Council Resolution 82, which condemned North Korea at the beginning of the Korean War; on behalf of the U.S., Gross voted in favor of the resolution. In fall 1950, Warren Austin returned from his leave of absence, and Gross continued to serve as Austin's deputy until 1953.
 Passage 3:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
