LAKE ERIE. 41 side of channel, keeping north of the range between the inner end of north pier and west side of the elevators in Erie. The general depth of water in Presque Isle bay is from 3 to 5 fathoms, mud, clay, or sand bottom, chiefly mud in deep water, and sand on the shoals; three fathoms of water can be carried to within 500 yards of the north and south shores of the bay, except opposite the railroad wharf at west end of city, where a shoal makes out from the north shore, one-third way across the bay, its extremity bearing W.S. W. & W., nearly a mile, from the Inner buoy (north). The outer buoy may be approached from the eastward on any course between S. S. - W.and 8S. W. by W.4 W. The range to carry through between the piers (W. S. W. 4+ W), is formed by the beacon-light on east. end of north pier (rED) and the white range-light on west end of same pier. From the west end of north pier a straight channel 200 feet wide and with not less than 16 feet water leads to the deep water of the inner bay. Continue on the course which leads between piers untilthe range-beacon on west end of pier is brought on with the beacon near southwest corner of keeper's dwelling; take this range until Inner Black buoy, No. 7, is passed. From this point steer for docks. ERIE. ERIE LIGHT-STATION.--A fixed white light, 3d order, visible 19 miles. 'Light gray conical tower, 60 feet high, with oil- room attached. Detached dwelling.
