FLAT ISLAND ST. FRANCIS HAEBOE. 663 



Shoal water, on which is a rock that generally breaks, extends 

 eastward 250 yards from the northern island, but otherwise these 

 islands are bold-to. 



Double Island bank, with 8 fathoms of water over it, bears 307°, 

 distant 900 yards from the northern Double island; it is said to 

 break in heavy gales. 



Flat island, west-northwestward 1^ miles from Double islands, is 

 a black rock about 20 feet high. 



The Skerries, a shoal with 8 fathoms of water over it, bears 43°, 

 distant f mile from Flat island ; it is said to break in heavy gales. 



Denbigh and Granby islands divide the large inlet between 

 Mecklenburg and Fishing-ship harbors into three passages, that again 

 converge to two inlets, Alexis river, the southern, extending inland 

 25 miles, and Gilbert river, the northern, 18 miles. These inlets con- 

 tain numerous islands and rocks with channels between them, but 

 they have been only partially surveyed, and should not be navigated 

 without a pilot. 



The southern side of Denbigh island is foul for ^ mile off. 



Granby island rises at l-j^ miles west-northwestward of its south- 

 eastern point to a conspicuous flat-topped hill, 461 feet high, and its 

 southern coast is steep-to. 



Fish rock, bearing 340°, distant 3| miles from Double islands, is 

 11 feet high, and separated by a narrow channel from the southeast- 

 ern point of Granby island. 



Copper island, about 600 yards southwestward of Fish rock and 

 separated from the southern side of Granby island by a channel ^ 

 mile wide, is 186 feet high, grass-covered and flat-topped, with steep 

 and bold-to coasts. Breaking rock, in the middle of the channel 

 between Copper and Granby islands, covers 3 feet at high water. 



Little Copper island, a small white islet, 35 feet high, lies just 

 southwestward of the western end of Copper island. 



Merchantman harbor, on the northeastern coast and near the 

 eastern end of Denbigh island, is fronted by Shinny island. It is 

 entered on either side of this island, and it affords anchorage in 7 

 fathoms of water, but the head must not be approached nearer than 

 400 yards. 



Williams harbor, on the southern side of Granby island and north- 

 ward of Merchantman harbor, affords good anchorage for small ves- 

 sels ; several Eskimo families live on its shores. 



St. Francis harbor, on the eastern coast of Granby island at 1^ 

 miles northward of Fish rock, is divided into two parts by a round 

 hill 82 feet high, northeastward of which are Chain rocks, low and 

 flat ; southeastward of the hill there is a low islet, and Pigeon island, 

 43 feet high, with a watch-house and flagstaff on it, lies in the 

 entrance at 300 yards farther southeastward.
