troit is directed to the numerous col- lisions with bridges and bridge piers in Duluth harbor which have occurred in the last year or two, resulting in the serious interruption of railway and highway traffic and imposing con- siderable loss on commerce in addi- tion to the damages to the structure. Maj. .Graham D. Fitch,. United States engineer at Duluth, has issued a warning to masters, citing three cases of collision with the Northern Pacific railway bridge in the last year, occurring in mild weather, and re- questing that all possible care be used in passing the bridges. Harbor rule 5 requires that "A steamer must em- ploy a tug or tugs whenever the con- ditions of weather, currents, etc., make the passage difficult or dangerous to either the vessel or the bridge," and this rule should be strictly observed. Particular caution is necessary at the Northern Pacific railway bridge owing to the narrowness of the draw openings, and these conditions should receive proper consideration from navigators until the new and larger draw spans now under construction are "completed. RELOCATION OF WRECK OF THE SCHOONER MAGNET.--The United States Lake Sur- vey steamer General Williams, which is engaged in sweeping the west end of Lake Erie, reports the relocation of the schooner Magnet, lying three miles NE. by E. % E. (true bear- ing) from Middle Sister Island. Sweep wires stretched 26 ft. below the water surface, at present stage, passed over the wreck without strik- ing. The least depth found was 27.5 ft. The water over the wreck is therefore good, and the vessel track clear. The Lake Survey sweeping opera- tions of this season. both in Lake Erie and Lake Huron, have shown that the wrecks of many years ago, even where they were leveled for the 12 or 14-ft. drafts of the early days, are still obstructions dangerous to 20-ft. navigation. It is the purpose of the Lake Survey to sweep over all the wrecks of the lakes, where they lie in depths likely to make them dangerous, in order to safeguard vessels from disaster by leveling these obstructions for future drafts. LAKE ST. CLAIR, ' At the close of navigation the St. Clair Flats Range lights, located at the head of the old cut or western channel through St. Clair Flats South pass, Lake St. Clair, will be perma- nently discontinued. The structures will remain to serve as daymarks. ' LIGHT NOT TO BE DISCONTINUED.--The TAE Marine. REVIEW historical coast light at St. Joseph, on the east shore of Lake Michigan, will not be discontinued as the lighthouse board had provided." Marine inter- ests opposed the move so _ strongly: that Senator William Alden of Mich- igan wired an appeal to L. O. Mur- ray, assistant secretary of commerce and labor at Washington, to delay his order. The light was to have been put out of commission Oct. 17. The light had been in constant ser- vice there -for over 50-years. REMOVAL OF TUNNEL AT CHICAGO.-- Washington street tunnel, under the Chicago river, is now a thing of the past, having recently been entirely removed. This tunnel, as every ma-- rine man is aware, has been a costly annoyance to shipping interests for a score of years past. Twenty feet of water may now be carried through the west draw. MILWAUKEE BREAKWATER WORK.--Ves- sel masters are complaining of the dangerous conditions in entering Mil- waukee in thick weather. The break- water is being extended and the ex- tent of it is marked by a gas buoy and boats cannot cross the line of work north of the buoy. Vessel men complain that there is no way of tell- ing the exact location of this buoy in thick weather. They claim that a crib should have been' placed there instead of the gas buoy and the fog signal and light also placed on it in- stead of at the end of the finished breakwater. The breakwater is to be extended 980 ft. The stone founda- tion will be completed this season, but no cribs will be placed until next year. The government authorities in answering the complaints of vessel masters simply say that they regard ~ the information in their bulletins and supplements as _ sufficient notice to vessel men. It is very true that these bulletins inform the master of exist- ing conditions but they do not fur- nish him with the means of safely navigating his vessel by them. When a master has no other way of verify- ing his position than by means of a -fog signal, which is not always to be relied upon, the mere fact that he knows that an obstruction exists, but neither knows his distance nor his bearing from it, is a mighty poor re- lief to him. - Milwaukee is a _ hard place to' find in a fog for the fog whistle cannot always be dependeed upon. To make the piers and pass the new breakwater work in safety 'a master must get a good bearing on the fog bell on the north pier. He gets the whistle first but in trying to pick up the bell is where the trouble 27 comes in, so that in getting a little too far to the north'ard he is liable to run foul of the new work. If he had any means of judging his dis- tance from the fog whistle he would have no trouble in passing clear of the end of the obstruction. OLD WRECKS.--The Lake Survey sweep- ing operations of this season, both in Lake Erie and Lake Huron, have shown that the wrecks of many years ago, even where they were leveled for the twelve or fourteen-foot draughts of the early days, are still obstruc- tions dangerous to twenty-foot navi- gation. It is the purpose of the Lake Sur- vey to sweep over all the wrecks of the lakes, where they lie in depths likely to make them dangerous, in order to safeguard vessels from dis- aster by leveling these obstructions . for future draughts. GAS BUOYS IN POSITION.--President Liv- ingstone of the Lake Carriers' Asso- ciation makes the following announce- ment: "The acetylene gas buoys at the outer end of the west channel at Bar Point are now in position. The red buoy carries a white flashlight, flash 5 seconds' duration, interval 3 seconds. The black buoy has a fixed white light." ENDORSEMENTS FOR COURSE eo FINDER. Capt. F, C. Watson, steamer Van Hise: 'Your work meets my expecta- tions fully and I consider the Course Finder an exceedingly useful addition to any boat's equipment. Its use- fulness is apparent at first glance and I am sure it will come into general use among vesselmen. I shall take pleasure in "boosting" it among my friends and acquaintances, though that is hardly necessary, as it will cer- tainly sell on its own merits." Capt. A. W. Holmes, steamer Venus: "Your Course Finder and Deviation Log Book are excellent works and are so useful and practical that they should be made a necessary part of every boat's equipment. They are just what has been needed for a long time." Capt. James Tindall, steamer Mid- land King: "Your Course Finder and Deviation Log are just the thing for every boat. They not only verify one's work and answer all purposes as well for the posted as the unposted. The work of keeping track of a ship's courses is reduced to almost nothing by their use."
