THOMPSON'S COAST PILOT. 23 Seul Choix Point bears from Gull Island, which is the west- ermost island of the Beaver group, NbyWiW 16 miles. The water is deep close to this point. You ean approach the point in from 30 to 55 feet water. Rocky bottom. FROM SEUL CHOIX POINT TO HAT ISLAND, THIRTY MILES, AS FOLLOWS: From Seul Choix Point EbyS2S 30 miles; thence on the same course 10 miles, to Point Waugoshance Lighthouse. This route passes 24 miles south of the White Shoals, and 1¢ miles north of Gray's Reefs. ' FROM 8ST. HELENA ISLAND TO ABREAST OF THE MANITOUS, NORTH ABOUT, AND TO CHICAGO, THREE HUNDRED AND TWENTY-TWO MILES. From St. Helena, after clearing the shoal which is due west from the island 2 miles, steer due west 40 miles; thence SWiW 16 miles; thence SbyWiW, for Chicago, 273 miles. This route is only 9 miles further than the Sheboygan route, and is far more preferable in the fall of the year. A vessel or propeller, by keeping the west shore aboard, can go with a NW and westerly wind in smooth water, and make her passage with ease; and in case of being driven down in thick weather to the northward and westward of the Beaver Island group, these routes will be found convenient for making the Straits, by keep- ' ing to the northward of them all, and come in to the eastward. Gull Island Shoal bears from Gull Island SbyE#H, from High Island SWbyW, and from the SW point of Beaver Island WNW. o There are two patches of shoal water a little to the south- ward and eastward of Gull Island Shoal, with 16 and 17 feet water on them. This reef is about 4% to 5 miles from Gull Island. Between Gull Island and High Island the water is deep, being from 22 to 168 feet, from shore to shore, and is nearly 6 miles wide. Due north carries you through midway. The water between High Island and the Big Beaver is deep, being from 386 to 138 feet. To run through this channel, keep about midway until you are abreast of Trout Island, steering
