GEEGOEY ISLAND SHAG EOCKS. 301 



Gregory island, north-northeastward, nearly 2 miles from Saddle 

 island, is about 600 yards long in a curve and 245 feet high. 



A pinnacle rock, 52 feet high, lies southwestward 150 yards from 

 Gregory island, and is nearly joined to it by reefs at low water; 

 close southwestward of this pinnacle is a small round islet, and the 

 channel between it and the shoal water extending 200 j^ards north- 

 ward from Saddle island is clear. 



Brandies rocks, a shoal 250 yards in diameter, the middle of 

 which bears 29°, distant 1,400 yards from the eastern end of Gregory 

 island, show by breakers with a slight swell; the eastern rock un- 

 covers 2 feet at low water. The northern end of Saddle island, open 

 westward of Gregory island, bearing 203°, leads westward; and 

 Little Shag rock in line with the middle of Lark harbor entrance, 

 bearing 194°, leads eastward of the rocks. 



Pearl island (or Big island), eastward 1 mile from Tweed island, 

 is I5 miles long, in an easterly and westerly direction, with a greatest 

 breadth of 1^ miles, and it is 845 feet high. Four curious pillars (the 

 highest of which is 597 feet high) stand on its eastern side, on the 

 northern part of a deep valley which separates them from the hill 

 in the southeastern part of the island. Shivery point, the northern 

 end of the island, has a rock with 5 feet water over it, bearing 83°, 

 distant 200 yards from it. 



Big Island cove is on the northeastern side of the island at about 

 ^ mile from Shivery point, and there are small shingle beaches at its 

 head, on which fishermen's huts are erected in summer. The water 

 is deep, except close to the shore, so only small vessels can anchor off 

 the cove. 



Cloue patches. — The soundings are irregular for 1,200 yards west- 

 ward of that part of the western coast of Pearl island which extends 

 about a mile southward from Shivery point, and are in places less 

 than 10 fathoms. A rock, with 4 feet of water over it, lies on this 

 bank, bearing 234°, 1,600 yards from Shivery point. The southeastern 

 end of Guernsey in line with the summit of Little Shag rock, bearing 

 220°, leads northwestward; and the summit of Blow-me-down, open 

 westward of Pearl island, bearing 177°, leads westward of this rock. 

 A rock, with 7 feet of water over it, bears 77°, distant 265 yards from 

 the 4-foot rock, and there is a 3-fathom patch between the 7-foot rock 

 and the island. 



A bank, with 5:^ fathoms water over its southern part, bears 251°, 

 distant 1,700 yards from Shivery point. 



Shag" rocks consist of two groups; the northern group is a round 

 islet 20 feet high, bearing 125°, distant ^ mile from the southeastern 

 end of Pearl island, with low rocks extending westward 100 yards, 

 and southeastward 300 yards from it. The southern group is a flat.
