sels should pass about' 50 ft: from the E. pier' to follow the middle line: of ' e. best water. Private dredging to deep- en the channel to the lumber docks is and has been in progress for some time. Fort: Wit Harbor, Wis,, is situated on the south shore of Lake Superior, about 34 miles east of Duluth; it is on Flag Lake, about MY mile within the entrance to Flag River. POINT ABBAYE SHOAL, MICH.--The bell and nun buoys marking the northern and southern edges of the Point Abbaye Shoal were withdrawn for the winter on Oct. 12.

[el GRAND ISLAND HARBOR ENTRANCE--MAN- HATTAN WRECK GAS BUOY WITHDRAWN FOR THE WINTER--The gas buoy mark- ing the wreck of. the steamer Man- hattan in the eastern approach to Grand Island harbor, has been with- drawn for the winter, and marked by a spar buoy of the same color. ST, MARY'S- RIVER--LITTLE MUD LAKE-- BUOY MOVED.--On Sept. 15, Little Mud .Lake upper buoy No. 14, a red spar, was moved 600 ft. southward of its former position and remoored in 20 ft. of water to matk the eastern edge of the channel opposite Stribling Pt. gas buoy No. 13. SHOALS REMOVED AT SUPERIOR HARBOR. --The United States Lake Survey at Detroit reports that dredging of shoals, off the mouth of Nemadji. river in the Superior harbor basin and front channel has secured at the present time a deep channel past the mouth of the river, 45 ft. wide at the narrowest portion. This least width is confined to a stretch 800 ft. long beginning opposite the mouth of the river and extending thence westerly. In the harbor basin the north line of deep water is 1,100 ft. north of end of ore dock No. 3 (marked: here by small red spar) and 800 ft. from end of ore dock No. 1, measuring out on the line of the docks. Red channel buoy No. 2 marks the edge of deep water at the turn opposite the mouth © of Nemadji river. "Small temporary buoys, red on starboard and black on port side coming in, define the nar-- row portion of channel. The work is in charge of Maj. Gra- ham D. Fitch, United States engineer at Duluth, and will be continued un- til later in the season. It is also ex- "pected to commence deepening the lake approach to Superior entry to 30 - ft. during October. NOTICE TO VESSEL OWNERS AND MAS- TERS--It is expected that the dams surrounding the rock cut of the West - Neebish "TRAE. MARINE. REVIEW \élvatufel. will "be broker through "on or about Oct. ing the water to flow through the new channel, although 'it: will not be available for navigation this season. The effect of this additional channel will be to lower the level of ' the water below the Sault locks, and down to -Sailors Encampment, the esti- mated amount of such lowering be- ing three to five inches. Since at this time of yéar the water level is falling naturally, vessels expecting to pass the St. Marys River after Oct. 15 should load to 'a draft of not more than 19 ft. 3 in. The actual depth of water at prevailing stage will be an- nounced on bulletin at the St. Marys Falls Canal office as heretofore, and overladen vessels will be subject to delay and lockage may be refused if this step is considered necessary to avoid possible groundings and _ ob- struction of channels.
