THOMPSON'S COAST PILOT, 23. High Island. The best anchorage is under.the east point of the island, in 5 to 7 fathoms, sandy clay. When laying here, should the wind chop round to the NW, you can run out, round the east end of the island, giving the point a good berth, and follow the island close round and come out to the westward, leaving Gull Island to port or to starboard pretty close to. The course from the south side of Gull Island to Rock Island Lighthouse is WSW, but if the wind should be southerly you will have to haul up a point higher, as a southerly wind always sets a stiff current through the passage and along the islands leading into Green Bay. ST. MARTIN'S ISLAND CHANNEL. In going through this channel, leave the Gull Islands to star- | board and St. Martin's Island to port; run through about mid- channel, and when abreast of the west end of St. Martin's, steer NW4W 15 miles for Point Peninsular; thence NNW 6 miles to Sand Point, Little Bay de Noc, giving the Point a berth of 4 mile, and haul round to the docks or come to anchor in7 fathoms.
