CAPE FOGO CLEEYS LEDGE. 525 



is for the guidance of the small craft which visit Tiltoii harbor during 

 the fishing season. 



Cape Fog'O, the eastern point of Fogo island, is a bold headland, 

 214 feet high. 



Ice. — Northern ice usually arrives on the east coast of Fogo island 

 between January 12 and 20, closing the coast with easterly winds. 

 Sometimes the coast is clear in April, at others, with a prevalence 

 of northerly winds, navigation is stopped during May, and even until 

 July. 



Current. — The current Avhich has been described as turning east- 

 ward along the northern coast of Fogo island after passing Eound 

 head, takes a southerly direction, following the eastern coast ; it is 

 affected by the tidal streams, the ebb or southgoing stream accelerat- 

 ing and the flood or northgoing stream retarding it. so that occa- 

 sionally at spring tides it is masked entirely. 



Rocks eastward of Fog'O island. — Lanes rocks are two rocks 

 lying at distances of 2^ and 3^ miles from Bound head along a line 

 bearing 67° ; the western rock has 3 fathoms of water over it and the 

 eastern rock has 2 fathoms. 



Clearing- marks. — Copper island, open eastward of cape Fogo, 

 bearing 175°, leads eastward, and Fogo head, open northward of Joe 

 Batts point, bearing 253°, leads northward of Lanes rocks. 



Barracks islets are situated on a bank of foul ground, about IJ 

 miles in extent, lying northeastward 1^ miles from the eastern Lanes 

 rock; the highest islet is 25 feet high. Pigeon ledge, eastward 1^ 

 miles from this bank, has 5 fathoms of water over it; and Inspector 

 rock, with 3 fathoms of water over it, lies southeastward 1,600 yards 

 from the bank. 



Cromwells ledge, bearing 62°. distant 11^ miles from Round 

 head, is about f mile in extent, with irregular rocky bottom. There 

 are two patches, |- mile apart, northward and southward, with 6 

 fathoms water over them, and ^ mile southward of the southern one 

 is a sounding of 4^ fathoms, which is the least-known depth on the 

 ledge. The sea breaks on the ledge in heavy weather. 



Snap rock, bearing 62°, distant 17| miles from Round head and 

 290°, distant 22 miles from Funk island, is a shoal having an extent 

 of about ^ mile, northeastward and southwestward, with a least depth 

 of 5 feet over it. In calm weather there is little indication of its 

 existence, but it breaks when there is any sea on. A current setting 

 eastward is usually experienced in this locality. 



Clerys ledge, on which there is a least depth of 5 fathoms, and 

 which breaks in bad weather, bears 62°, distant 10 miles from Round 

 head, and lies 1 mile west-southwestward of the 4^-fathom depth on
