AS WITH ALL CARTOGRAPHIC REPRESENTATIONS, what this map of 1878 Toronto doesn't show is every bit as interesting as what it does. Perhaps more so. According to an 1878 city directory, Toronto at the time had numerous newspapers, an extensive network of rowing, lacrosse and curling clubs, 36 real estate agents, a dental college, an Oddfellows lodge, four hoop skirt makers and three dance teachers. A man named James Authors made artificial limbs from a storefront on King Street, just east of Yonge. There was even a historical society, the York Pioneers, which, as it happens, still operates.
