they lye; within those islands (if you have not wind to carry
your ship into the harbour) you may anchor; the best birth for
getting under way with any wind, is to bring the island Raz (a
low island) to bear south or south half west one mile, in 14 or
15 fathoms water, soft bottom; there is nothing in the way
between this anchorage and the harbour; you will observe in the
entrance a small island or rock, fortified, called Lage; you sail
about mid-channel between this island and Fort Santa Cruz,
observing that the tide of flood sets upon Santa Cruz point, and
the ebb upon the island; the soundings from the outer anchorage
decrease from 14 fathoms, where we lay, regularly, till near
abreast of the Sugar-loaf, where it is six and a half fathoms:
from this depth you drop into 12, 14, and 16 fathoms. Run up, and
anchor off the town in 17 or 18 fathoms, clear soft ground.
