In June, 1862, W. F. Durfee, a cousin of Z. S. Durfee, was asked by Ward to report on Kelly's process. The report[112] was unfavorable. "The description of [the apparatus] used by Mr. Kelly at his abandoned works in Kentucky satisfied me that it was not suited for an experiment on so large a scale as was contemplated at Wyandotte [Detroit]." Since it was "confidently expected that Z. S. Durfee would be successful in his efforts to purchase [Bessemer's patents], it was thought only to be anticipating the acquisition of property rights ... to use such of his inventions as best suited the purpose in view." [112] W. F. Durfee: "An account of the experimental steel works at Wyandotte, Michigan," _Transactions of the American Society of Mechanical Engineers_, 1884, vol. 6, p. 40 ff. Thus the first "Bessemer" plant in the United States came into being without benefit of a license and supported only by a patent "not suited" for a large experiment. Kelly seems to have had no part in these developments. They took some time to come to formation. Although the converter was ready by September 1862, the blowing engine was not completed until the spring of 1864 and the first "blow" successfully made in 1864. It may be no more than a coincidence that the start of production seems to have been impossible before the arrival in this country of a young man, L. M. Hart, who had been trained in Bessemer operations at the plant of the Jackson Brothers at St. Seurin (near Bordeaux) France. The Jacksons had become Bessemer's partners in respect of the French rights; and the recruitment of Hart suggests the possibility that it was from this French source that Z. S. Durfee obtained his initial technical data on the operation of the Bessemer process.[113] [113] Research in the French sources continues. The arrival of L. M. Hart at Boston is recorded as of April 1, 1864, his ship being the SS _Africa_ out of Liverpool, England (Archives of the United States, card index of passenger arrivals 1849-1891 list No. 39). During the organization of the plant at Wyandotte, Kelly was called back to Cambria, probably by Daniel J. Morrell, who, later, became a partner with Ward and Z. S. Durfee in the formation of the Kelly Pneumatic Process Company.[114] We learn from John E. Fry,[115] the iron moulder who was assigned to help Kelly, that--
