The exceeding heat of the last few days had caused our excellent friend Mr. Knowles great inconvenience (and his friends had shared it with him), but the unpleasant conviction was gradually growing stronger in our minds that it would not be prudent for him to undertake the rapid and protracted journey on which we were about to engage. When he arrived in Quebec he had come to the same conclusion, and to our great sorrow, we felt obliged to admit that he was adopting the wisest course in taking his passage in one of the fine steamers of the Allan Line, direct from the St. Lawrence to Liverpool. He arranged accordingly to sail on the Saturday--the day after we left Quebec. Among the causes for regret at quitting this interesting city, none was felt more than the necessity for saying adieu to one whose close observation, sound judgment, and practical knowledge had rendered his companionship so useful, just as his amiable qualities had made him a most agreeable fellow-traveller. Our party was doomed to suffer still another reduction. Lord Stafford felt that the pressure of his Parliamentary duties, at a time when most important measures were under discussion, would force him to return to London without visiting the Western States. At 4 o'clock the Governor-General, attended by Colonel de Winton and others of his personal suite, came to the station with his uncle and the party who were bound for Montreal. The kindness of the General Manager of the Pennsylvania Railway, Mr. Thompson, had followed us into Canada, and the President's car, with special carriages, was awaiting us at Quebec. And so we glided out of the station, amidst the cheers of the small crowd of friends, and the waving handkerchiefs of the ladies who had been good enough to see us off, and the fire of fog-signals in lieu of artillery. We were bound to assist at a function that evening, and the special train was tolerably well filled by members of the Legislature and of the Council, and many others who were going to witness the first trial of the electric light under the auspices of the Canadian Electric Light Company, at the depot of the Q. M. O. & O. Railway at Hochelaga. The Premier, Mr. Chapleau, the Provincial Secretary, Mr. Paquet, and other ministers were in the train. The Duke, to do honour to the occasion, and to get a little fresh air and keep his hand in perhaps, drove the engine from Quebec to Three Rivers, a distance of seventy-eight miles, which, according to the Montreal papers, is the first occasion upon which a Duke drove a train in the Dominion, and probably will be the last.
