Sketch of By Town, Ottawa River, Founded in 1826

Source is "The British Dominions in North America; or a Topographical and Statistical Description of the Provinces of Lower and Upper Canada, New Brunswick, Nova Scotia, the Island of Newfoundland, Prince Edward, and Cape Breton," published 1831. J & C Walker - John Walker, Alexander Walker and Charles Walker, known collectively as J & C Walker (active 1820-95) - were engravers, draughtsmen and publishers working through the 19th century. The firm engraved a large corpus of work for the British Admiralty and produced numerous high-quality geographical maps and nautical charts for a variety of other institutions. This map of Bytown (now Ottawa) shows early street names.
