In 1877, Danielson hired Charles Henry Dow, a young journalist with an interest in history. At the "Journal," Dow developed a "news index" which summarized stories of historic interest. It is possible this was an early inspiration for Dow's later development of his "stock index" at the Wall Street Journal. While at the "Journal" Dow wrote a series on "The History of Steam Navigation between New York and Providence." Dow also traveled to Colorado to report on the Colorado Silver Boom and the Leadville miners' strike; these stories were published in May and June 1879. On the Colorado trip, Dow traveled with a team of Wall Street financiers and geologists, leading Dow to leave Providence for New York City in 1879 to advance his career as a reporter on mining stocks.
