This map by George Keefer Jr. shows the Welland Canal, completed in 1829, connecting the Welland River to the Grand River. The opening of this canal allowed ships to bypass Niagara Falls and opened Great Lakes ports to international shipping through Montreal and Quebec City. A small profile at bottom reveals that the lock system had to overcome 300 feet of elevation between the two lakes. Engraved by Amos Doolittle. The map is accompanied by William Hamilton Merritt's “Account of the Welland Canal” within a complete disbound issue of The American Journal of Science. This issue also includes a plate showing the method used to dig the canal as well as a small map of the Louisville and Portland Canal. There are no past sales records and only two institutional holdings per OCLC.
