The North American Boundary Commission carried out the determination and marking of the boundary along the forty-ninth parallel dividing the United States and Canada. The boundary survey was carried out by two commissions appointed in the U.S. and Britain in 1856, led respectively by Archibald Campbell and Col. J.S. Hawkins, with Major J.G. Parke and Captain R.W. Haig as the astronomers. The survey began in 1857, and was completed in 1861. The final report was signed by the two commissioners in Washington in 1869.
RGO 61 contains observations and computations from stations engaged on the survey of the North American boundary.
The papers were found at the Royal Observatory, Greenwich, in 1898 by Otto Klotz, who was then in the employ of the Government of the Dominion of Canada.
