Ironduquot Embankment. - This interesting section of the Erie Canal, which was first opened on the 15th inst. is distant from this place about eleven miles. The approach to it from the west is lateral to, and situated on an elevated roll or ridge of land, of about 80 rods in length, which rises from the bed of Ironduquot creek, and forms one of its banks, and is, in its turn, used to form one side of the embankment of the Canal, till you come to the main valley of the creek, where the course of the Canal crosses it. This natural bank rises, generally, to within about six feet of the level of the Canal, which is there built on it.
The valley of the Ironduquot, where the Canal must pass, is seventy-two feet lower than the banks, and forty rods wide. The base of the embankment constructed, is 304 feet, through which is built a culvert, of twenty-six feet chord, with a semi-circular arch of 244 feet in length. The ground, on which this structure was placed, was a soft, alluvial marsh: - in consequence, it became necessary to place in on piles, of which thee are nearly one thousand.
The scenery is magnificent! While you are silently and peacefully navigating the tops of an artificial and natural mountains, the eye takes in, at a single glance, the whole fertile valley of Ironduquot, and the mind expands itself to the amazing importance of the internal improvement which this work connects, and has now thrown into operation. The expense of the above work is probably $40,000. - Rochester Telegraph.
