Alabaster returned to Siam in 1873 to serve as private secretary to King
Chulalongkorn (Rama V). He oversaw many modernization efforts at this time, many of Thailand’s firsts. This included the building of roads, bridges and libraries (Thailand’s first road, Charoen Krung, was overseen by Alabaster), the founding of the national museum, post office and the royal cartography service, and sending the sons and daughters of royalty and high-ranking positions abroad for study. One of his roles was Director of the Royal Museum and Garden; he sent botanical specimens to China for his brother Chaloner, an amateur plant collector. He was the first director of the kingdom's map-making division, established in 1875, and had teams of surveyors develop maps for use in building roads and telegraphs as well as protecting territorial waters. == Death ==
