I learned afterwards that the order to all the juries was to commence their labors the morning after the opening of the exposition, and have their reports in within three weeks. The superintendent must have been officially informed of this order, and he deliberately misled me. I have always wondered if this was his revenge on me for not having run on Sunday as he ordered. So far as concerns their judgment on the engine, “before the exposition was over” it had won the admiration of every engineer in Europe. Mr. John Hick of Bolton, then the leading builder of stationary engines in England, and afterwards the head of the great engineering firm of Hick, Hargreaves & Co., made a visit to the engine every afternoon during his stay, sometimes watching it for a long time. It had a fascination for him. He told me that no amount of testimony would have made him believe that an engine could have been made to run so smoothly and silently at such a speed, or to maintain such a vacuum. He said that if my engine shown in London had made anything like so favorable an impression on his mind, he would have made me a proposition for its manufacture; but it did not. The reason for this I had learned long before, the reason why it did not impress any one favorably, it was non-condensing. He added that he had since made other arrangements which made such proposition now impossible. I knew what those arrangements were. He had two years before taken up the manufacture of the Corliss engine, under the management of Mr. William Inglis, a Canadian engineer, by whom this engine had been successfully introduced into England. I knew Mr. Inglis well, and rejoiced in his success, as every one who knew him must have done. As for any rivalry between us such a thing was never thought of, there was room for both of us ten times over. I was very courteously waited upon by a French engineer, who asked me if I were acquainted with the Deluel vacuum-gauge. I told him that I was not. He said that he was happy to introduce it to my notice. The vacuum shown by the Bourdon gauge on my condenser was so remarkable, especially with an air-pump running so swiftly, that it could not be accepted with confidence by engineers, unless actually shown by the mercurial column. The Deluel gauge was the only one in which this was employed. With many apologies for what was indeed the greatest kindness to me, he ventured to suggest that the Deluel gauge be placed on the condenser. He kindly gave me the address of the firm in Paris. A sharp Yankee will probably recognize him as an accomplished drummer for the house. This did not occur to me, but I am under obligation to him all the same.
