rld, but I shall now add some further
observations that occurred to me in this voyage. The island of Mayo is
about 7 leagues in circumference, of a roundish form, with many small
rocky points shooting out into the sea a mile or more. Its latitude is 15
degrees north, and as you sail about the isle, when you come pretty nigh
the shore, you will see the water breaking off from those points; which
you must give a berth to and avoid them. I sailed at this time two parts
in three round the island, but saw nothing dangerous besides these
points; and they all showed themselves by the breaking of the water: yet
it is reported that on the north and north-north-west side there are
dangerous shoals that lie farther off at sea; but I was not on that side.
There are 2 hills on this island of a considerable height; one pretty
bluff, the other peaked at top. The rest of the island is pretty level
and of a good height from the sea. The shore clear round hath sandy bays
between the rocky points I spoke of, and the whole island is a very dry
sort of soil.

OF THE CAPE VERDE ISLANDS; ITS SALT POND COMPARED WITH THAT OF SALT
TORTUGA; ITS TRADE FOR SALT, AND FRAPE-BOATS.

On the west side of the isle where the road for ships is, there is a
large sandy bay and a sandbank of about 40 paces wide within it which
runs along the shore 2 or 3 miles; within which there is a large salina
or salt pond, contained between the sandbank and the hills beyond it. The
whole salina is about 2 miles in length, and half a mile wide; but above
one half of it its commonly dry. The north end only of the pond never
wants water, producing salt from November till May, which is here the dry
season of the year. The water which yields this salt works in from out of
the sea through a hole in the sandbank before mentioned, like a sluice,
and that only in spring tides when it fills the pond more or less,
according to the height of the tides. If there is any salt in the ponds
when the flush of water comes in it presently dissolves: but then in 2 or
3 days after it begins to kern; and so continues kerning till either all
or the greatest part of the salt water is congealed or kerned; or till a
fresh supply of it comes in again from the sea. This water is known to
come in only at that one passage on the north part of the pond; where
also it is deepest. It was at a spring of the new moon when I was there;
and I was told that it comes in at no other time but at the new moon
