Preliminary Report on Gowganda Mining Division District of Nipissing Ontario
by W. H. Collins
The Algoma-Nipissing boundary line was run in 1897 by Alexander Niven, O.L.S. These surveys, with representations of some of the larger lakes, had been compiled by the Geological Survey of Canada on a scale of 16 miles to one inch;[1] and on a scale of eight miles by the Crown Lands Department of Ontario. With these as a guide and summary of the existing geographical knowledge it was decided to make a micrometer and prismatic compass survey of both branches.
