from London to bail out the company. The company was renamed Theo H. Davies & Co., and Green went into business by himself. Green served as acting British consul in 1859 after the health failed of both William Miller and his replacement Busvargus Toup Nicolas (1819–1859), and again between William W. F. Synge (1826–1891) and James H. Wodehouse. Politics On 17 February 1874, he was appointed minister of foreign affairs, replacing Charles Reed Bishop. A major milestone of his administration was ratifying the Reciprocity Treaty of 1875 with the United States on 17 June 1876, which was also signed by Ulysses S. Grant. It had been negotiated for a long time by Elisha Hunt Allen and Henry A. P. Carter. He served until 5 December 1876, when Carter replaced him. He was appointed again as minister of foreign affairs on 22 September 1880, and served until 20 May 1882. He filled in as acting minister of the interior from 28 May to 31 October 1874. At that time he was replaced by Walter M. Gibson. After Gibson fell from power the 1887 Constitution of the Kingdom of Hawaii was imposed by force. This gave it the name "Bayonet Constitution". Green was told to form a new cabinet; he included Lorrin A. Thurston, a leader of the bloodless coup, as minister of interior. Green became minister of finance on 1 July 1887, and served until 22 July 1889 when his health started to fail. Geology Green was fascinated by the volcanoes in the Hawaiian islands. By 1855 he wrote a series of articles on local geology in the Sandwich Islands Monthly newspaper of Abraham Fornander. His ideas on the formation of the earth, based on the nebular hypothesis of Pierre-Simon Laplace, shocked the local conservatives who literally believed in creation according to Genesis. In 1857 he published an article in the Edinburgh New Philosophical Journal based on the theory of Jean-Baptiste Élie de Beaumont. In 1859 he went on expeditions to view the erupting Mauna Loa and nearby Kīlauea and Hualālai on Hawaii island. He hosted the adventurer Isabella Bird when she came to visit, and gave her a tour of the volcanoes. His first book on his tetrahedral hypothesis was published in 1875. It was "...a work which was neglected or ridiculed at the time of its appearance." The journal Nature published only a one-line notice for the book. He
