MIDDLE DOCK ISLANDS BIG SHOAL, 121 



Middle Dock islands are 200 yards southwest b}^ west of Stearin 

 rocks and occupy a space 400 j^ards in diameter. The two southern- 

 most are conical, with grassy summits, the western and highest being 

 37 feet above high water. These two have no dangers off their south- 

 eastern sides. The rest of the group are low, and the northern one 

 covers at high water, but there are no outlying dangers beyond 200 

 yards distance from the group. There is a clear passage between 

 these and Stearin rocks. 



Anclior rock, bare, flat, and 8 feet above high water, is separated 

 from the south side of Middle Dock islands by a clear channel 200 

 yards wide, and is steep-to. A sunken rock lies midway between it 

 and Northwest island. 



Northwest island, 115 feet high, and 400 yards southwestward 

 of Middle Dock islands, is formed of several wooded hillocks covering 

 dark rock, the highest falling steeply to the northwestern extreme. 

 Some small pinnacle rocks lie close-to, but there is no sunken danger 

 near, except on the eastern side. 



West island, lying 450 yards southward of Northwest island, 

 is wedge shaped, 300 yards long and 200 yards broad. The summit, 

 which is wooded, falls steeph'^ to the northern extreme, and is 115 

 feet above high water, A green mound, with a conspicuous patch of 

 turf near its summit, is joined to the south extreme by a beach of 

 shingle. A ledge of rock that dries only at low water springs ex- 

 tends 200 yards from the eastern side. 



Western rock, the western of White islands, is a gray islet 24 

 feet high, with a little grass near its summit. A reef of rocks ex- 

 tends 200 yards northward, and there are rocks between it and West 

 island, but no danger beyond 200 yards from them, A rock awash 

 at high water lies close southward, and a shoal, with T feet of water 

 on it, is a short distance southwestward. A rock that dries is a little 

 more than 200 yards, bears 301° from West island. 



Caution. — There is apparently no safe passage for ships among 

 White islands. 



Mackerel shoal, with 14 feet of water, bears 292'', distant about 

 400 yards from West island. 



Harry rock, with 8 fathoms of water, bears 250°, distant 700 

 yards from Northwest island. 



Big- shoal, with 4 fathoms of water, bears 205°, distant 950 yards 

 from Western rock, and is the highest part of a bank 200 yards in 

 diameter within the depth of 10 fathoms. 



Shoal bank, with 14 feet water, bears 236°, distant li-ff miles 

 from Western rock, and is a small pinnacle, with deep water close 

 to it. 



The coast from Parfrey point after a slight curve close west of 

 that point trends in nearly a straight line to the entrance of Clatise
