From Dymond Reef you take two bearings of Token Rocks lighthouse: 110°M, and half an hour later 050°M. In between you steered 155° by compass for 4.0 miles (log), with a stream setting 184° at 1.8 knots. Variation 6°W. Find the two true bearings and the movement over the ground you use to advance the first line of position.
