On the evidence given at the third trial, not only as regards the invention of the rollers, but as regards the other questions at issue, no other decision was possible than one that involved the annulment of Arkwright’s patent, and it was arrived at without hesitation. It does not necessarily follow that the evidence was complete, and on one point, as already noticed, it probably was not. In an application for a new trial, made shortly afterwards, evidence regarding the crank and comb, similar to that obtained by Baines, and from the same source, was mentioned, and also evidence to rebut that given by Kay and Highs. The judges, however, were convinced that there was not sufficient ground for the application and in November, 1785, the patent was cancelled.[349] [Footnote 349: Espinasse, _ibid._, pp. 447-448.] After the trial, _The Manchester Mercury_, in a comment on the evidence, stated that it appeared from it, that the most material engines in Arkwright’s patent for preparing cotton were the cylinder carding-engine and the roving-engine. The first was so old that its origin could not be traced, and improvements had been added to it by Hargreaves, Whittaker, Wood and others, long before Arkwright claimed it. The roving-engine and the spinning-engine were one and the same thing, and the evidence proved that it was invented by Mr. Hayes of Leigh, although Arkwright had enjoyed a monopoly of it for fourteen years, while the real inventor was prevented by poverty from seeking redress.[350] [Footnote 350: 5th July 1785.] There is some truth in this view, but certainly not the whole truth. It must be recognised that neither Highs nor Arkwright was the first to conceive the principle of attenuating cotton by the roller-method. That honour undoubtedly belongs to Lewis Paul, and the principle was crudely stated in the specification[351] of the patent he obtained, and embodied in the machinery he constructed, thirty years before either of them had begun to experiment. But how far were these men or either of them indebted to Paul for knowledge of the method? Taking into account the lives and the characters of the two men, Arkwright was more likely to have been acquainted with it than Highs. In his peregrinations about the country he had the opportunity, and with his unbounded push and curiosity it is fairly certain that, if anything could be known of it, Arkwright was the man to know it. Indeed, if Kay’s account of the conversation he had with Arkwright at Warrington may be trusted, he went far to avow the fact.[352] [Footnote 351: Baines, _ibid._, pp. 122-123.] [Footnote 352: _Trial_, 25th June 1785, Kay’s evidence.]
