This is a very dangerous shoal, and is not laid down in any chart that I
have seen: It seemed to extend itself to the southward and westward, all
round the two westernmost of these three islands, for near six miles,
but about the eastermost island there seemed to be no danger; there was
also a clear passage between this island and the other two. The latitude
of the eastermost and westermost of these islands is 5 deg. 31' S. The
eastermost is distant thirty-four miles due west from Tonikaky, and the
westermost lies ten miles farther.

In the afternoon of the 25th, we found the water much discoloured; upon
which we sounded, and had five-and-thirty fathom, with soft mud. Soon
after we went over to the northermost part of a shoal, and had no more
than ten fathom, with soft mud. In this place, where we found the water
shallowest, it was very foul; it seemed to be still shallower to the
southward, but to the northward of us it appeared to be clear. We had no
observation this day, by which I could ascertain the latitude; but I
believe this to be the northermost part of the shoals that lie to the
eastward of the island Madura, and in the English East-India Pilot are
called Bralleron's Shoals, the same which in the Dutch charts are called
Kalcain's Eylandens. By my reckoning, the part that we went over lies in
5 deg. 50' or 5 deg. 52' S. and 3 deg. 36' to the westward of the island Tonikaky,
or S. 84 deg. 27' W. distance sixty-nine leagues. At eleven o'clock the
same night, we saw, to the northward of us, the southermost of the
islands Salombo. I make its latitude to be 5 deg. 33' S. and its longitude
west of Tonikaky 4 deg. 4', at the distance of about eighty-two or
eighty-three leagues. It bears from the last shoal N.W. by W. 3/4 W. at
the distance of about fourteen leagues. It is to be remarked, that
hereabout, off the island of Madura, the winds of the monsoons are
commonly a month later in settling than at Celebes. The variation here
was not more than half a degree west; and we found the current, which
before set to the southward, now setting to the N.W.

In the afternoon of the 26th, we saw from the mast-head the island of
Luback, and had soundings from thirty-five to forty fathom, with a
bottom of bluish clay. The latitude of this island is 5 deg. 43' S. and
its-longitude 5 deg. 36' west of Tonikaky, from which it is distant about
one hundred and twelve leagues. Its distance west from the islands of
Salombo is thi
