32 / take a 4-pt. bearing of Cana Island lighthouse to verify your position; at 10:30 Cana Island light bears 4 points from the course and at 10:41 it bears abeam. How far are you off the light? Evidently you allowed too much for leeway, or your compass is a little off, or may be the wheelsman let her work up too much; but at any rate you are in too much on the course to fetch right. The distance from abreast Cana Island to a point 4 miles (the distance you should be off Pilot Island when abreast) abreast of Pilot Island on this course is 15 miles, how much will you have to alter your course from the distance you found you were off Cana Island to fetch you the 4 miles off Pilot Island? When Pilot Island bears 4 points from tHe course it is 11:40 and at 12:01 it bears abeam. How far are you from Pilot Island? What is the first bearing by compass of the 4-point bearing you took of Pilot Island and what is the second bear- ing by compass? From this last po- sition it is just 8 miles to Fisherman Shoal and the course you are steering brings you right on to the shoal. You wish to pass 11%4 miles outside of the buoy, how much will you have to alter your course in order to do it? From Fisherman Shoal you wish to steer a course right through to Pt. aux Barques leaving it on your port beam at a distance of 4 miles. true course is NE % N, no Var., Dev. 4-pt.

During October, Lake Superior should hold its present level; all the other .lakes should fall somewhat as follows: Lakes Michigan and Huron 23% in., Lake Erie 3% in. Lake On- tario 41%4 in. It must be understood The. THe Marine Review that these are averages, and an un- usually wet October would' check this, and a 'very dry October ent cause greater lowering. During September, Lake Superior rose 214 in. and is practically at the average September stage of the past ten years. It is 2% in. higher than last year, and 6% in. higher than in 1890, but 2%4 in. lower than in 1905, and 8!4 in. lower than in 1876. Lakes Michigan and Huron fell % of an inch during the month, but are still 614 in. above the average Sep- tember stage of the past ten years, 314 in. higher than last year, 7 in. higher than in 1895, but half an inch lower than in 1905, and 2 ft. lower than in September, 1876. Lake, Erte: fell:.3 in, during the: month, but is still over 6 in. above the average September stage of: the' past ten years, 5 in. higher than last year, a foot and a half higher than in 1895, but an inch lower than in 1904, 1%4 in. lower than in 1890 and 14 in. lower than in 1876. Lake Ontario fell 4 in. during the month. It is, however, 814 in. above the average September stage of the past ten years, than last year, and 214 ft. above the stage of September, 1895, but 434 below that of 1905, and 10 in. below the water of 1876.
