 is covered with grass and is steep-to on its northern and eastern sides, 

 but shoal water extends 100 yards southwestward of it. 



Rock.— Bearing 149°, distant 1,665 yards from Lobster island 

 and 114°, distant 1^ miles from Thwart island, there is a rock with 22

St. Johns harbor. — At 1^^ miles southeastward of the northern 

 point of Thwart island is an islet from the southern point of which 

 shoal water extends southeastward for 265 yards; and 750 yards 

 south-southeastward from this islet is an island 200 feet high, with a 

 reef awash at low water, extending 300 yards northward of it. Two 

 hundred yards south-southeastw^ard of the island, 200 feet high, is a 

 peninsula extending northward from an isthmus situated IjV miles 

 to the southward. The southeastern end of this peninsula is a re- 

 markable wooded conical hill 400 feet high. St. Johns harbor lies 

 westward of the island 200 feet high and the peninsula. The northern 

 part of the harbor, entered northward of the island 200 feet high, is 

 clear of shoals and affords anchorage in about 13 fathoms, mud 

 bottom. The southern part of the harbor is separated from the north- 

 ern by a bay, over w^hich there is a depth of 4 fathoms. Southward 

 of the bar the depth increases to 8 and 9 fathoms, but the space is 

 limited. 



The entrance between the island 200 feet high and the peninsula 

 has a depth of 4 to 5 fathoms in the middle, but it is narrow and suit- 

 able only for small craft. 



Thwart Island harbor is a bight immediately westward of the 

 wooded conical hill 400 feet high at the southeastern end of the 

 peninsula forming St. Johns harbor. The middle of the harbor has 

 a depth of 6 fathoms in it, but its shores are foul and there is little 

 clear space. 



The southeastern coast of Thwart island from Thwart Island 

 harbor trends southeastward 3 miles to its southern point; depths of 

 less than 5 fathoms extend nearly 600 yards off it in places, and a 

 rock with 11 feet water over it lies 600 yards off this coast bearing 

 224°, distant Ij^ miles from the summit of the island, 210 feet high, 

 forming the southwestern entrance head of Thwart harbor. 



The western shore of the bay of Exploits within Philip head 

 trends southwestward and rises to the Monkeys Lookout, a conspicu- 

 ous hummock. southwestAvard of which the shore rises to some hills a 

 short distance inland. A rocky ledge with general depths of 11 to 

 20 fathoms over it extends southeastward for 1,200 j^ards from Philip 

 head, and on this ledge at | mile from the head is a patch with 5^ 

 fathoms least water over it.
