The mystery of the Chinese tea chest label

When MIT historian Tristan Brown first examined a Chinese tea chest label displayed as a relic of the Boston Tea Party, he had no reason to doubt its story.Descendants of Boston blacksmith Thomas Wells had donated the label to the Old South Meeting House in 1987, saying it had been recovered during the destruction of British tea in 1773. Because so few objects from the protest survive, the label appeared to offer a rare material connection to the event.But after a year of archival and linguistic research, Brown reached a different conclusion: The label was made nearly a century later.The decisive clue lay hidden in its Chinese text. Earlier researchers had approached the text through Mandarin, but Brown found that one sequence of characters was being used phonetically. Read in Cantonese, it rendered the name “Smith, Archer,” identifying Smith, Archer & Co., an American trading firm active in East Asia during the 1860s and 1870s.The discovery does not make the label historically insignificant. Instead, it reveals a different story — one connecting Chinese migration, Pacific commerce, family memory, and the ways Americans constructed the history of the Revolution.Brown presents his open-access findings in “Tea Chest Label,” published July 3 in the June 2026 issue of the American Historical Review. What began as an inquiry into a supposed Boston Tea Party relic became a study of how ordinary objects acquire historical authority, and how historical memory itself is made.The project began in 2024, when the American Historical Review issued a call for essays on 76 objects connected to 1776, the year the United States declared independence from Britain.“I’m a historian of China and don’t usually work in American history, but the idea of taking on one of 76 artifacts for the 250th anniversary of the U.S. sounded like a fun challenge,” Brown says.As he considered which object to study, Brown recalled seeing the intriguing Chinese label during a visit to the Old South Meeting House, a major site of public debate in Revolutionary-era Boston and the place where colonists gathered before the Tea Party.The object had stayed with him.Following the evidenceThe label offered Brown an unusual point of entry into the history of the Boston Tea Party. Its apparent significance was heightened by the scarcity of surviving objects from the event.That scarcity reflects the nature of the protest itself. The destruction of the tea was a criminal act, and participants had strong reasons to conceal their identities and avoid punishment by the British Crown. Even today, no completely definitive list exists of the people who took part.“That is one reason why the event remains shrouded in a degree of mystery,” Brown says.With that uncertainty a given, Brown pursued two lines of investigation simultaneously: establishing the label’s provenance, and deciphering the label’s wording.At the outset, he learned that scholars associated with the British Museum and Harvard University had examined the label. Their assessments had not definitively authenticated the label as a Tea Party relic, but neither had they ruled out an 18th-century origin.“I believed it was real,” Brown says. “None of the parties who had previously assessed the label’s provenance concluded definitively that it wasn’t from the Boston Tea Party. And frankly, it was hard to imagine how an American family with no ties to China could have possessed a label written in formal Chinese listing the exact teas that were traded in the region.”Brown spent months interviewing Wells descendants and searching for original documents that might connect the label to the 1773 protest. At the same time, he began tracing how the family tradition surrounding the object had developed.Because claims of family participation in the Tea Party are often difficult to verify, Brown worked closely with members of the Wells family throughout the project, and found in them willing and generous partners. As the evidence began pointing away from the Revolutionary era, the research required both scholarly rigor and personal sensitivity.“The Wells family, especially Charles Wells, were extraordinary collaborators,” Brown says. “They cared deeply about their ancestor’s legacy and the label’s history, and they wanted the truth as much as I did. This is their discovery as much as mine.”Cracking the labelThe Chinese wording on the label presented a separate challenge.Brown could see that part of the text did not function like ordinary Chinese prose, but its meaning remained elusive. The breakthrough came when he revisited the way earlier scholars had pronounced the characters.Previous translations and interpretations had relied on Mandarin, China’s official language rooted in the northern part of the country. Brown gradually recognized that one sequence of characters was being used phonetically to represent a foreign company name. When pronounced in Cantonese — the dominant language of the 19th-century commercial networks in which the label circulated — the characters reproduced the name “Smith, Archer.”That reading identified Smith, Archer & Co., a New York-based import-export firm with offices in East Asia during the 1860s and 1870s. The company acquired Chinese and Japanese teas for shipment to American markets.The label also named Yuan Tianbo, a Cantonese merchant connected to that trading network, whom Brown later traced to Yokohama, Japan in the 1860s.The linguistic clue therefore did more than reveal a company name. It established that the label belonged to the world of 19th-century Pacific commerce, not the tightly controlled Canton trading system of the 1770s.“That was the moment the entire story changed,” Brown says. “Once we could date the label, we finally knew where to look.”From East Asia to the American MidwestOnce Brown had identified the company, he could begin reconstructing the label’s likely route into the Wells family’s possession.The trail led to John Milton Wells, a relative who traveled from Michigan to the San Francisco Bay Area during the Gold Rush era from 1848 to 1855. Although John Milton did not strike gold, his years in California changed the course of his life. After returning to Michigan, he worked as a grocer and operated a business recorded in commercial directories as the “California Tea Store.”A surviving trade card associated with Wells advertised imported Asian teas. Together with family letters, census records, and local business directories, it points to the commercial world through which a label produced for an East Asian tea merchant could have entered the Midwestern family’s collection. The label was therefore likely acquired through the family’s 19th-century tea business, rather than during the Boston Tea Party.Brown argues that its Revolutionary pedigree probably developed later, amid the centennial commemorations of the 1870s, when many American families were emphasizing their connections to the nation’s founding era.By the early 1900s, the story had appeared in a local newspaper, which reported that the label had been taken from a tea chest during the Boston Tea Party. Repetition in family accounts, newspapers, commemorative culture, and eventually museum interpretation helped transform an unverified tradition into an apparently authoritative history.“The label shows how 19th-century global trade, Asian migration, and family storytelling together reconfigured American revolutionary memory by manufacturing the very relics that seemed to authenticate that memory,” Brown writes.A different kind of historical artifactBrown’s investigation also demonstrates how new research tools are allowing historians to revisit questions that once appeared settled.Digitized commercial directories made it possible to trace Smith, Archer & Co. across East Asian ports. Searchable newspapers helped Brown follow the development of the Wells family story. Attention to Cantonese, rather than Mandarin, unlocked a company name that had gone unrecognized in earlier interpretations.“Though the tea chest label is not from the Revolutionary War era, it’s still an important educational artifact documenting China’s long-standing trade with the Americas and the ways Americans have long looked to China to tell stories about their own country’s past,” Brown says.The discovery changes the label’s historical significance, rather than diminishing it. The object’s value lies not in what it was reported to have witnessed in 1773, but in what it reveals about how later generations used globally circulating objects to construct memories of the American Revolution.The label also preserves an important truth beneath the mistaken family tradition: The tea destroyed in Boston Harbor came from China. Its journey from an East Asian commercial network to a Midwestern family and finally to a Boston museum illustrates how American revolutionary memory became intertwined with Pacific trade and migration.For Brown, the project offers a broader lesson about historical scholarship as an ongoing process of questioning, debate, and discovery.“History is never finished,” Brown says. “Even objects that have sat in museums for decades can reveal entirely new stories when we ask new questions.”
