NOTICE TO MARINERS. The subscriber begs to state to those navigating the Lakes, that 'Thomp- gon's Coast Pilot is the original one, prepared by him in 1858, and has gone through four editions, with all the corrections suitable to the march of the times and the improvements on the 'great chain of Lakes, or Inland Seas. The increased demand for the work induces me to bring forward a fifth edition, materially amended for 1869. I beg further to state, that the Coast Pilot issued by Barnet, ; in Chines is a spurious copy of my first edition, printed in Chicago in 1859. The object of this notice is to advise my friends, and the Lake Navigator, who wish to purchase a useful book for Lake purposes, to call for Thompson's Coast Pilot, and not the Coast Pilot of Barnet. ; Since the last edition was printed I am happy to state that there are a great many improvements going on, such as opening new cuts for channels, building piers, lighthouses, beacons, placing ranges for harbors and laying down buoys, etc., many of which are finished, and others to be pushed for- ward as fast as possible. The first improvement in point of utilityvis the St. Clair Flats, where a new straight cut is being made, of a depth of water sufficient for the larg- est class of vessels. This cut or channel, when finished, will be of the greatest importance to the merchant, as well as to the sailing community. Next in importance is the ranges for Maumee Bay and River. These ranges are so well placed and constructed that there is nothing wanting for the safe navigation of that Bay and River. The new light on the pier-head at Cleveland, Ohio, will be of ereat service to those making that port. Buffalo Harbor has been improved by dredging, and repairing the piers. The extension of the Lighthouse pier, which will be 300 feet, will prove a great protection to the harbor, and the Erie Basin breakwater--the exten- sion above spoken of--will be commenced in a shorttime. On Lake Huron and Saginaw Bay and River, also Sauble River, and Thunder Bay River, ' improvements are being pushed forward with rapidity. Dredging in Sagi- naw River, at the entrance and up the river. I have no doubt that this sea- son vessels of the largest class will be able to go up river as far as Saginaw City and Salina. At Sauble River, piers are being built, and when. com- pleted will make a good harbor of refuge, as well as a good: lumber region. Saw mills and fishing are the principal features of this place.
