NORTHERN ARM LONG ISLAND. 377 



Anchorage may be obtained in 8 to 13 fathoms water in How 

 harbor, observing that the water shoals in its northwestern part. 



Tides. — It is high water, full and change, in How harbor at 

 Th. 18m. ; springs rise 4 feet, neaps 1^ feet. 



Northern arm, westward 3 miles from How harbor, extends 2 

 miles to the northward with a width of ^ mile, but it is open 

 southward. 



Anchorage. — There is good anchorage in this arm at about ^ mile 

 off a small river on the eastern shore, with Hare island, which forms 

 the western entrance point of the arm and is 115 feet high and nearly 

 joined to the mainland at low water, just open of the mainland, bear- 

 ing about 202°, in 8^ fathoms water. 



Northwest arm, separated from Northern arm by Plare island 

 and a projecting point northwestward of it, is completely open south- 

 ward ; anchorage sheltered from offshore winds may be obtained in 5 

 to 8 fathoms water; a bank of bowlders fringes the whole of the 

 western shore of Northwest arm between Seal bay and Fournier 

 point. A large stream runs into the head of Northwest arm. 



Brent islands, southward 3^ miles from How harbor, are two 

 islands close together and connected by shoal water; North Brent 

 island, the northeastern, being nearly bare, and South Brent island, 

 the southwestern, being covered with brushwood; each is about 1 

 mile across and the passage between them and the mainland to the 

 westward is shallow. A rocky ledge, awash at high water, extends a 

 short distance northward from Brent islands, and shoal vrater north- 

 westward f mile, with Vert island near its end. 



Anchorage. — West river flows into the bay southwestward of 

 these islands, and off its entrance at about 1 mile southwestward of 

 Brent islands, there is fair anchorage in 5 to 6 fathoms water, to 

 reach which pass southeastward of Brent islands. 



Shoal. — A: shoal, with 2^ fathoms of water over it. lies in mid- 

 channel between South Brent and Direction islands, and in the fair- 

 way to the anchorage ; from the shoal the northeastern end of Direc- 

 tion island, which is 82 feet high, bears 233°, distant ^ mile. 



Long island, 1 mile south-southwestward of South Brent island, 

 is 2y% miles long, in a north-northeasterly and south-southwesterly 

 direction, 300 to 1,000 yards in width, and separates Western and 

 Southern arms. The island is thickly wooded, except near its west- 

 ern point; the southwestern end is joined to the mainland at low 

 water. 



A shoal, with 3 to 15 feet of water over it, extends east-northeast- 

 ward, 300 yards from the northeastern end of Long island, and there 

 is a depth of 15 feet at about 200 yards off the southeastern coast of 

 this island, but near the middle the shoal water extends off more than 

 400 vards.
