Apart from a statement of Highs that Kay’s wife told him of what had passed between her husband and Arkwright, there is only Kay’s testimony, which was not always convincing, to go upon, and clearly under the circumstances he was not likely to err in Arkwright’s favour. On the other hand, it is incredible that the two could have been associated as they were without Highs’ experiments having been mentioned, assuming that he had carried on any experiments. In view of the statements of Highs, this can hardly be doubted: there is nothing to suggest that he was deliberately untruthful. At the same time, this does not prove that Arkwright had not conceived the idea of spinning by rollers before his contact with Kay at Warrington. The difficult point to explain is why Arkwright sought out Kay at all, coupled with the fact that, from this time, he devoted his whole activity to the construction of the spinning-machine. The statement that previously he had been experimenting in mechanics, and that he sought out Kay for some purpose thus connected, does nothing but leave the difficulty unsolved. The only other scrap of evidence regarding the question as to whether Arkwright did obtain Highs’ invention, was contained in a reference of Highs to a conversation he had with Arkwright at Manchester, when he charged him with having obtained it. Arkwright’s attitude, on this occasion, as described by Highs, was, however, as appropriate to a man with a clear conscience, who had no desire to enter into an unpleasant argument, as to a man who was guilty and wished to evade a charge.[348] One point that may be noticed is that as this conversation was said to have taken place about the time when Highs’ machine was exhibited in the Exchange, the date of the exhibition, as revealed by its advertisement, fixes the conversation one year nearer to the time when Arkwright took out his first patent than has always been supposed. On the side of Highs, the great difficulty is to explain why his claim was allowed to lie so long in abeyance, seeing that he was not without friends in Manchester, men, moreover, who, it may be assumed, would not have been slow to attack Arkwright’s patent had the slightest opportunity been offered. [Footnote 348: _Trial_, 25th June 1785, Highs’ evidence. Evidently Arkwright made a gesture of impatience, and suggested that even if Highs had any claim to the invention, he had not gone forward with it, and, in such a case, another man had the right to do so.]
