MNT Yt Wee te DRUM UNA ce ee NOTICE TO MARINERS. The subscriber begs to state to those navigating the Lakes, that THompson's Coast Pinot is the original one got up by him in 1858; that during my absence by sickness, and while®occupied en the Lakes, the printer, Mr. James Barnet, of Chicago, h thoyght fit' to copyrigigt my work in his own name, and now issues & spufious edition in the name of The Coast Pilot for the Lakes, with one small chart of Lake Michigan in it, poorly got tp, with part of my own courses laid down on it, and more than a dozen ertors thereon. Not only this, he threatens to prevent me from sell- ing my own'work, the manuscript copy of which was entered for a second edition in Detroit, in April, 1861, with charts of all the harbors on the south shore of Lake Superior, and the whole coast of the same. _ The object of this notice is to inform my friends and the Lake navi- gator who wishes to purchase a useful book for Lake purposes, to call for THompson's Coast Pruor, and not the spurious edition of Barnet's. I would further state that I commenced the work over twenty years ago, but lost all my books and papers, by fire, on board the Nile steamer, at Milwaukee, in 1850, and it took from that time to 1858 to gather the requisite material for the first edition. Since that time I have lost no op- portunity of correcting the errors which appeared in it. I now present a fourth edition in a reliable shape, corrected for 1865. Those wanting a large correct chart of Lake Michigan, will find them at all the ship chandlers mentioned on the outside cover of Thompson's Coast Pilot for the Upper Lakes. THOS. 8S. THOMPSON, Licensed Pilot for the Lakes. IMPORTANT SOUNDINGS IN MILWAUKEE HARBOR.
