A stereoview engraving of a steamboat running the Lachine Rapids above Montreal. It is probably intended to represent one of the Canadian Navigation Company steamboats that operated on the Saint Lawrence River and Lake Ontario in that period.
Chisholm's all round route and panoramic guide of the St. Lawrence was published annually in Montreal between 1870 and 1881. The Canadian Navigation Company merged with the Richelieu Company in 1875 to form the Richelieu and Ontario Navigation Company.
The "C. R. Chisholm & Bros. Montreal" is stamped into the reverse.
