PREFACE. In presenting the fifth edition of the Coast Pilot to the Lake Navigator, the subscriber would respectfully say that, by the assistance of the lake surveys, and his own observations on his usual tour round the Lakes, he has been enabled to amend the work very materially. At the same time, he would tender to the fraternity his hearty thanks for the appreciation of his efforts which has rendered a fifth edition necessary, and would further recommend it to the young navigator as well as to those who are from the Seaboard, or otherwise unacquainted. All the late improvements, new lighthouses, buoys, beacons, docks, etc., will be given; also, custom house regulations, and other information relative to Lake Navigation. which will ren- der it a necessary companion for all Pilots on the great chain of Lakes.
