MUSSEL flARBOR BARREN ISLAND. 141 



awash at low water. To clear these rocks when entering, keep the 

 southern shore aboard. 



Green island is a small rock 30 feet high situated ^ mile north- 

 west of the northern entrance point of Mussel harbor. A small reef 

 lies north-northwest of it. 



Mussel harbor, a fine basin on the western side of Long island at 

 3^ miles from Buffet head, is well sheltered throughout, with good 

 holding ground. It is 1^ miles long north and south, ^ mile broad, 

 with a depth of 19 to 21 fathoms water, mud bottom, and is divided 

 into two arms at its northern end ; small vessels anchor in the north- 

 western arm, but a short sea heaves into the other with southwesterly 

 Avinds. 



There are three islands at the mouth of Mussel harbor; the entrance 

 is southward of the southern of these islands, keeping in mid-channel 

 to avoid a rock situated a few yards from the south shore. An islet 

 lies on the western side of the northern arm, and several shoals are 

 westward of it; the passage is eastward of the islet. 



North Wild cove, IJ miles southward of Mussel harbor, affords 

 no shelter, nor does South Wild cove, 1^ miles farther southward. 



Barren island, 315 feet high, is separated from Mussel Harbor 

 entrance and the land southward of it by a clear deep channel 400 

 yards wide. Several shoals lie near the western coast of the island, 

 which should not be approached within I mile. A small islet, 27 feet 

 high, is situated close to the southern point of Barren island, and a 

 rock, that nearly always breaks, lies 100 yards off the islet. 



Merasheen and "White Sail banks are extensive banks lying 

 south-southwestward of Merasheen island and separated from the 

 shoals off that island by a deep channel 2 miles wide. 



Telegraph rock, with 11 feet water over it and the shoalest rock 

 on these banks, lies 191°, distant 8| miles from Scrape Cove head, 

 and from it shoals, with 5 to 9 fathoms water over them, extend to 

 Upper Big shoal, which has 8 fathoms water over it, and is situated 

 1 mile within the southern end of Merasheen bank and south-south- 

 west 15 miles from Scrape Cove head. Southern ridge, | mile south- 

 southwestward of Upper Big shoal, has 13 fathoms on it and is the 

 southern limit of the shoalest part of the bank. 



Rocks. — On the northern portion of White Sail bank are North- 

 ward rock, with 7 fathoms ; Joe Ground, 5| fathoms ; and Jeans rock, 

 6 fathoms water, all lying on a general southwesterly bearing from 

 Scrape Cove head, and Jeans rock, the western, being distant 6 miles. 

 To the southeastward of these 1| miles is Burges ground with 6 

 fathoms water. There are also several patches of 6 to 9 fathoms on 

 White Sail bank. 



Clearing mark. — Margaret and Breakheart points in line bearing 

 47° leads northwestward of all these dangers.
