The party now left Rochester at nine o'clock, and went on board the canal packet-boat Ohio. The canal, between Lockport and Rochester, runs the distance of sixty-three miles through a tolerably level country, and north of the Rochester ridge. This ridge consists of a series of rocks, which form the chain of mountains which commences north of Lake Erie, stretches eastward to the Niagara river, confines it, and forms its falls; then continues its course, and forms the different falls which are north of Lake Ontario, and is at length lost in the neighbourhood of the Hudson. The canal runs a distance through sombre forests, when they reached Lockport on the 20th of August, about seven o'clock in the morning. At this place the canal is carried over the ridge by five large locks, through which the water is raised to the height of seventy-six feet. The locks are ten in number, being arranged in two parallel rows, so that while the boats ascend in one row, they may descend at the same time in the other. [_Travels_: We left Rochester at nine o'clock, on board the canal packet-boat Ohio, Captain Storch. The canal, between Lockport and Rochester, runs a distance of sixty-three miles, through a tolerably level country, and north of the Rochester ridge. This ridge consists of a series of rocks, which form the chain of the mountains which commences north of Lake Erie, stretches eastward to the Niagara river, confines it, and forms its falls, then continues its course, and forms the different falls which are north of Lake Ontario, and is at length lost in the neighbourhood of the Hudson. It has only been within the last year that this part of the canal has been passable; its course is through dense sombre forests.... We reached Lockport on the 20th of August, about 7 o'clock in the morning. At this place the canal is carried over the ridge by five large locks, through which the water is raised to the height of seventy-six feet. The locks are ten in number, being arranged in two parallel rows, so that while the boats ascend in one row, they may descend at the same time in the other. Through this arrangement the navigation is greatly facilitated, and the whole work, hewn through and surrounded by large rocks, presents an imposing aspect.]
