During her time in Paris during the war La Motte formed a close friendship with the American expat writer Gertrude Stein. Researchers have speculated that Ernest Hemingway's influential unadorned style may have been influenced by La Motte's own writing, through Stein's mentoring. After the war, La Motte travelled to Asia, where she witnessed the horrors of opium addiction. These travels provided her with material for six books, three of them explicitly dealing with the opium problem: "Peking Dust" (1919), "" (1919), "Opium Monopoly" (1920), "Ethics of Opium" (1922), "Snuffs and Butters" (1925) and "Opium in Geneva: Or How The Opium Problem is Handled by the League of Nations" (1929). The Chinese Nationalist government awarded her the Lin Tse Hsu Memorial Medal in 1930. Yellow corydalis  Yellow corydalis is a common name for several plants and may refer to:     Staker Wallace  Patrick "Staker" Wallace (born 1733) was an Irish freedom fighter, perhaps born at Teermore, in Bulgaden-Ballinvana parish of County Limerick, Ireland, near the town of Kilfinane. He achieved some fame as an Irish patriot when he was brutally executed for independence activities by a pro-British nobleman in 1798. Most commonly known as Staker Wallace or The Staker, his first name was most likely Patrick. His nickname was given to him after death. Some sources give his first name as William or Edmond (Edmund), but these are less likely than Patrick. In her 1909 book about her ancestor, Eunice Graham Brandt referred to Staker as William. After being beheaded, his head was put on a stake for everyone to see. Thus, Staker Wallace. The monument in his honour in Martinstown, Limerick, refers to him as Edmond. Unfortunately, contemporary news accounts in the "Limerick Chronicle" are long-lost. Nonetheless, his correct first name can be established from other sources. According to traditional Irish naming patterns, the first-born son was named after his paternal grandfather. Both of Staker's sons named their first-born sons Patrick. A history of Limerick published in 1866 included a list of sentences passed by the General Court Martial in Limerick on 4 July 1798. Included on the list: "Patrick Wallis, for collecting subscriptions for procuring the assassination of Chas. S. Oliver, Esq., to be hanged at Kilfinane, his head to be affixed on one of his own pikes, and placed on the castle."
