When British Columbia entered the Dominion, on the 20th of July, 1871, it was agreed that within ten years from that date a line of railway should be constructed from the Pacific Ocean to a point of junction with the existing railway systems in the Provinces of Ontario and Quebec. Mr. Fleming's services in connection with the Intercolonial Railway marked him out as the most suitable man in the Dominion to prosecute the preliminary surveys of the Canadian Pacific. Accordingly his services were secured by the Government for that purpose, and he was appointed Chief Engineer. In the summer of 1872 he started across the continent on a tour of inspection. He was attended by a capable staff of assistants. Among the latter was the Rev. George M. Grant, the present Principal of Queen's College, Kingston, who accompanied the expedition in the capacity of Secretary. The party left Toronto on the 16th of July, 1872, and travelling by way of Sault Ste. Marie, Nepigon, Thunder Bay, Winnipeg, Forts Carlton and Edmonton, the Rocky Mountains, Kamloops and Bute Inlet, reached Victoria, B.C., on the 9th of October following. Those who wish to inform themselves as to the literary and social aspects of that momentous journey may consult Mr. Grant's journal, as it appears in the pages of "Ocean to Ocean." Those who wish to know the scientific and more practical results of the expedition can only become acquainted with them through Mr. Fleming's elaborate report. Mr. Fleming continued to be the Government Engineer until about a year ago, when he resigned his position, owing as it is understood, to some difference of opinion with the Government as to the location of the line of the Canadian Pacific Railway. His topographical knowledge of the country is unrivalled, and his professional standing is such as might be expected from the importance of the great public works which he has superintended. In recognition of his talents, and of his services to Canada and the Empire, Her Majesty some time ago conferred upon him the dignity of a Companion of the Order of St. Michael and St. George. In addition to the work on the Intercolonial already mentioned, and to many elaborate and voluminous reports upon the various enterprises wherewith he has been connected, Mr. Fleming has contributed numerous interesting and instructive papers to the _Canadian Journal_ and other scientific periodicals. He has also written many articles on subjects connected with his profession for the daily press. Within the last few months a proposition of his with respect to the establishment of a new prime meridian for the world, 180° from Greenwich, has been approved of by the Imperial Academy of Sciences of St. Petersburg, Russia, the secretary whereof recently conveyed information of the fact in a letter addressed to the Governor-General of Canada.
