The rapids at the Little falls are divided just below the village by an elevated island of everlasting rocks, which arrests its progress and causes an incessant roar and foam. The canal for a mile below this spot is a perfect encroachment upon the bed of the river--the wall which divides it from the river is powerful and strong, that the labor and expense attending its erection must have been immense. I was shown on the village side of the river, the old canal and locks by which this rapid was passed, before the great modern improvement was projected. It was constructed more than 30 years since by a company of Englishmen, and was considered at that time a wonderful production of genius. But when contrasted with the present improvement, it dwindles into insignificance; the upper section is still used to supply the feeder, and crosses the aqueduct. The country still continues poor on both sides, while the narrow valley of the Mohawk presents very fine land. The passenger can supply himself with provisions and grog at all the lockhouses along the line at a very low rate. We arrived at 5 o'clock at the long level commencing at the village of Frankford; the canal is now one entire uninterrupted sheet of water for 70 miles, without a solitary lock; we have passed enough however to suffice for a while, having ascended upwards of 40 since leaving Schenectady, a distance of 80 miles. Very soon after entering the long reach, which is the summit level of the canal, the country begins to assume a different appearance, and the view is not so confined as heretofore. As the afternoon is a very pleasant one, the prospect is truly delightful.
