128 GEORGIAN BAY, these range light-houses but clear enough to see Red Rock light-house, the latter should be kept between the bearings of E. by N. % N. and N. 4% E. until the weather clears up, to avoid Richmond rock on the north side of the track, and Clark rock on the south side.) On this range the following buoys will be passed on the port hand: One off Richmond rock, distant 1,700 yards; one off McGowan rock, distant 750 yards; one a 21-foot spot (lying 1% miles E. % S. of Red rock light-house), distant 150 yards; one off Van- koughnet ground, distant 250 yards. On the starboard hand will be found one off Knight shoal, distant 475 yards; and one off Three Star shoal, dis- tant 350 yards. This range should be kept on for a distance of 8 miles from Sequin bank gas buoy or until the buoy off Vankoughnet ground is passed (should this buoy be displaced, a vessel may turn when Twin rock beacon is in line with the southwest side of the trees on Reid islands) when a vessel may haul to S. E. % S. to bring the Jones island range lights in one. At night, if the buoys cannot be picked up, a vessel may wait until the lights are almost in one before turning, as she will have plenty of space to the northeastward of the range and need not bring the leading mark exactly on until within half a mile of Twin rock. This range should be kept for a distance of 234 (34%) miles or to within a quarter of a mile of Hooper island shoal gas buoy. On the range the black buoy at Twin rock will be passed at 75 yards distance on the port hand. The following red spar buoys. will be passed on the starboard hand: Ariel rock, distant 250 yards; Hall reef, distant 300 yards; 21-foot spot near Twin rock, distant 30 yards; and Telegram rock, distant 200 yards. When about 400 yards from Hooper island shoal gas buoy begin turning slowly and head for Spruce island shoal gas buoy. The only buoy to be passed on this range will be the red one off Borer bank, distant 350 yards <A vessel on this reach should keep (as nearly as possible) Hooper island shoal gas buoy astern, and Spruce island shoal gas buoy ahead bearing E. 34 S. When about half a mile from Spruce island shoal gas buoy, or when Gordon rock light comes in line with the west end of the western Reid island, haul for the beacon on Cameron island bearing E. 7% S. to pass from 50 to 150 yards south of the gas buoy and to avoid the 16-foot rock lying 275 yards N. E. by E. 34 E. from McClelland rock and marked by a red spar buoy on the starboard hand. As soon as Jones island light comes in line with the southwest side of the middle Nias island bearing S. 34 W., haul for the west end of Davy island and keep Scott island in the gap north of it (Davy. island) N. E. by E. % EF. One black buoy marking the east end of a spit from Spruce island will be passed on this reach, distant about 250 yards. As soon as Kill Bear point appears open north of the north Sister island, steer for it bearing E. % S. This should give the red buoy off Carling rock a berth of about 50 yards. This course may be steered as far as the north Sister island, leaving Davy rock buoy 400 yards on the port hand and giving the island a berth of about 100 yards. When the north Sister island comes abeam, Depot island light (fixed red) may be seen bearing E. S. E. Steer for it thus, giving Long's island and Cadotte point berths of 100 yards. The whole of the south side of Depot island may be approached to within 100 yards and the wharves steered for. If wishing to proceed to Parry Sound, after passing the north Sister island, steer to pass about 100 yards south of Kill Bear point until Mowat island comes in sight bearing N. E. 1% N., when haul E. by N. Y% N. for BY (334) miles or until abreast Three Mile point. Give the latter and Two Mile point a berth of 200 yards and bring Bobs point just open of Deep- water point bearing S. E. by E. % E. to pass between McKerrel rock and the spit from Shoal point. Deep-water point shore should be kept best aboard in entering the harbor to avoid the spit from Bobs point (marked by a black spar buoy). : When leaving Parry Sound, before heading for the outlet take care to be well over to the southeast part of the Deep-water point shore and keep
