The line of no variation is marked distinctly on the best maps of Canada, by the division line between the townships of Stamford and Niagara, seven miles north of Niagara. At Toronto in 43 deg. 39' north latitude, and 78 deg. 4' west longitude, twenty-four miles north-east of Niagara, the variation in 1832 was more than 2 deg. easterly. The shore of Lake Huron at Nottawassaga Bay, forty miles north-west of Toronto, is again the line of no variation. Thus a magnetic meridian lies between Fort Erie and Nottawassaga. A magnetic observatory is established by the Board of Ordnance at Toronto, near the University, and placed in charge of two young officers of artillery, which says a good deal for the scientific acquirements of that corps. I shall perhaps hereafter advert to this subject more at large, as the volcanic rocks have much to do with the needle in Canada West. END OF VOL. I.
