Thus did hope alternate with despondency as the days and weeks wore away and nothing tangible was accomplished. All who saw the working of the telegraph were loud in their expressions of wonder and admiration, but, for reasons which shall presently be explained, nothing else was gained by the inventor at that time. An old friend of Morse's, the Reverend Dr. Kirk, was then living in Paris, and the two friends not only roomed together but Dr. Kirk, speaking French fluently, which Morse did not, acted as interpreter in the many exhibitions given. Writing of this in later years, Dr. Kirk says:-- "I remember rallying my friend frequently about the experience of great inventors, who are generally permitted to starve while living and are canonized after death. "When the model telegraph had been set up in our rooms, Mr. Morse desired to exhibit it to the savants of Paris, but, as he had less of the talking propensity than myself, I was made the grand exhibitor. "Our levee-day was Tuesday, and for weeks we received the visits of distinguished citizens and strangers, to whom I explained the principles and operation of the Telegraph. The visitors would agree upon a word among themselves which I was not to hear; then the Professor would receive it at the writing end of the wires, while it devolved upon me to interpret the characters which recorded it at the other end. As I explained the hieroglyphics the announcement of the word, which they saw could have come to me only through the wire, would often create a deep sensation of delighted wonder; and much do I now regret that I did not take notes of these interviews, for it would be an interesting record of distinguished names and of valuable remarks." On the 10th of September, 1838, Morse enjoyed the greatest triumph of all, for it was on that day that, by invitation of M. Arago, the exhibition of his invention before the Institute of France, casually mentioned in one of his letters to his daughter, took place. Writing of the occasion to Alfred Vail, he says:-- "I exhibited the Telegraph to the Institute and the sensation produced was as striking as at Washington. It was evident that hitherto the assembled science of Europe had considered the plan of an Electric Telegraph as ingenious but visionary, and, like aëronautic navigation, practicable in little more than theory and destined to be useless. "I cannot describe to you the scene at the Institute when your box with the registering-machine, just as it left Speedwell, was placed upon the table and surrounded by the most distinguished men of all Europe, celebrated in the various arts and sciences--Arago, Baron Humboldt, Gay-Lussac, and a host of others whose names are stars that shine in both hemispheres. Arago described it to them, and I showed its action. A buzz of admiration and approbation filled the whole hall and the exclamations '_Extraordinaire!' 'Très bien!' 'Très admirable!_' I heard on all sides. The sentiment was universal."
