GEORGIAN BAY. 123 of the breakwater pier are marked by the Department of Public Works of Canada by striped spar buoys. The depth between these two buoys is about 12 feet. The 14-foot channel passes to the westward, and the 20-foot channel to the eastward of this middle ground. Temporary Range Lights and Beacons--Hydrographic Notes. Shore Range Lights.--Temporary range lights, locally known as "shore range,' have been established and are maintained by the Corporation of Collingwood, in the south extremity of the harbor, which in one indicate the middle of the 20-foot channel from its outer extremity, outside the west breakwater pier, to the curve near the fixed red light on the crib in the harbor. The front light of this range stands upon the shore in the south part of the harbor at a point 330 feet S. 17° W. from the northwest ex- tremity of Fleming's wharf. It consists of two fixed white lantern lights six feet apart vertically, hoisted on a pole painted white, having a dia- mond-shaped white slatted beacon on top. The back light pole stands on the south side of Second street, 130 feet west from its intersection with the west side of Cedar street, and is distant 1610 feet S. 10° W. from the front light pole. Two fixed white lights, shown from lanterns 6 feet apart vertically, hoisted on this pole, are shown. The pole is 55 feet high, and has on its top a diamond-shaped slatwork beacon, 12 feet high by 8 feet wide, the whole painted white. ' Elevator Day Beacons.--The middle of the 20-foot channel leading to the elevator is marked by two day beacons. The front beacon consists of a diamond-shaped slatwork, painted white, attached to a mast rising 32 feet above water level, on the outer or northwest end of the elevator wharf. The back beacon consists a diamond-shaped white mark, painted on the northwest end of the elevator, at a height of 40 feet above the water. ; These two beacons in one, bearing S. 531%4° E., mark the middle of the 20-foot channel leading from the south end of the curve to the elevator. This channel is 110 féet wide. Sailing Directions.----Vessels approaching Collingwood harbor from the northward or northwestward should bring the red light on the crib in the middle of the harbor in line with the breakwater pier light, bearing S. % E., and keep them so until Nottawasaga island appears its own width open north of the north fall of Blue mountain, W. 4 N., to clear Lockerbie rock. (In day time this range is not easily picked up, but when exactly on the beacons appear a little west of the red light in the harbor.) When this mark opens up gradually haul to the eastward and bring the shore range on bearing S. 54 W. Keep this on until abreast of the end of the east breakwater, when gradually turn, keeping the black buoys on the curve well aboard until the elevator beacons are in one, S. E. % E., if bound thither. If bound for the G. T. R. or Town wharf, bring the gap between the two wharves ahead and the crib light astern, S. E. % E. Only 15 feet of water will be found on this last line. Channels to Wharves.--A channel 80 feet wide with a depth of 14 feet has been dredged from a point immediately outside the crib light to the wharf of the Collingwood Meat Company, and from this other channels 12 feet deep Tead to the Iumber wharves of Messrs. Charlton. These are all in the extreme east end of the harbor. Position of Middle Ground--The Middle ground is a straight strip about 30 feet wide, with about 12 feet of water on it, which lies between the 20-foot and the 15-foot channels, in the straight cut leading up to the elevator wharf, and not near the outer light, as indicated in that notice. It is marked by striped buoys. Dry Dock.--Work is in progress on an enlargement of the dry dock in Collingwood harbor. When completed it will be 530 feet long and 78 feet wide, with 16 feet on the mitre sill.
