of research into his spying proclaim Morley "arguably the best secret agent the United States produced during World War I". Shortly after the war several of Morley's contemporaries voiced their misgivings over the duplicitous nature of the espionage work that Morley and several of his colleagues had been suspected of. One notable critic, the famous anthropologist Franz Boas, published a letter of protest in the December 20, 1919 edition of The Nation. Without naming the suspected archaeologists, Boas' letter denounced these Central American operatives who had "prostituted science by using it as a cover for their activities as spies". Ten days after the letter was published, the American Anthropological Association censured Boas for this action in a 21-to-10 formal vote on a resolution distancing the AAA from Boas' views. The ethical debate surrounding such "archaeologist-spies" continues into the present, with some commentators noting the dangers and suspicion it throws upon others engaged in legitimate archaeological fieldwork, particularly those who work or seek to work in "sensitive" government-controlled areas. Fieldwork in Mexico and Central America Morley was to devote most of the next two decades to fieldwork in the Maya region, overseeing the seasonal archaeological digs and restoration projects, returning to the United States in the off-season to give a series of lectures on his finds. Although primarily involved with the work at Chichen Itza, Morley also took on responsibilities which extended Carnegie-sponsored fieldwork to other Maya sites, such as Yaxchilan, Coba, Copán, Quiriguá, Uxmal, Naranjo, Seibal and Uaxactun. Morley rediscovered the last of these sites (located in the Petén Basin region of Guatemala, to the north of Tikal). Believing that there must be many more as-yet unknown ancient Maya sites in the area, Morley advertised a "bounty" in return for news of such sites to the local chicleros, who ranged through the jungles seeking exploitable sources of natural gum; in due course he was rewarded with the information which led to its rediscovery. He also bestowed its name, uaxactun, from the Mayan languages, after a stela inscription he found there which recorded a Maya Long Count Calendar date in the 8th cycle (i.e., "8-tuns"; the name could also literally mean "eight stones"). During this time, Morley established a reputation for trustworthiness with the local Yucatec Maya around Mérida, who were still suffering from the depredations of the Caste War of Yucatán against the Mexican government. Over the years, he was
