Copy letter (in Robert Young’s hand). Thank you for the letter which was an answer to the letter sent to John Wesley Hackworth, England; no question in his mind that Hackworth was the inventor of the blast pipe; Hackworth’s place in the World’s Columbian Exposition; arranges for Pangborn, who is in charge of the exhibit to meet Samuel Holmes. Referenced in Robert Young, Timothy Hackworth and the Locomotive (London: Locomotive Publishing Company, 1923), p. 375.
