to answer
the signals made by the _Echo_[A6]. Why, in the neighbourhood of so
formidable a danger, not compare the points of the two ships, as is usual
when vessels sail in company? The captain of the frigate was not even
informed of the signals of the corvette. At eleven o'clock, she bore off
the larboard bow; and soon after he perceived that the direction of her
course made a pretty large angle with ours, and that it tended to cross us
passing a-head; he soon perceived her on the starboard: it is affirmed that
her journal states that she sailed the whole night W.S.W. ours does the
same. We must necessarily have hauled to the larboard, or she to the
starboard, since at day-break the corvette was no longer in sight.

At sea a vessel may easily be perceived at the distance of six leagues.
From midnight till six in the morning, she must have gained above six
leagues of us, which is not to be imagined, for she sailed much slower than
we and stopped every two hours to take soundings. To explain this
separation we must necessarily admit either that the frigate steered more
south, or the corvette more west, if the two vessels had run on the same
tack it would be impossible to explain it.

Every two hours the frigate brought-to, to sound; every half hour the lead
was cast without lowering the sails; we were always upon shallows, and
stood out to sea, to find a greater quantity of water: at length about six
o'clock in the morning we had above a hundred fathoms; we then stood-to the
S.S.E.; this course made almost a right angle with that which we had
followed in the night: it bore directly in-shore, the approach to which, in
this place, is rendered terrible by a very long reef, called Arguin, which
according to instructions we had on board extends above thirty leagues in
breadth.[12] According to the instructions given by the Minister of the
Marine, this danger is avoided by running only twenty-two leagues in the
open sea; it is true they recommend not to approach the shore but with the
greatest precaution, and with the sounding line in the hand: the other
ships of the expedition which sailed according to those instructions all
arrived at St. Louis without any accident, which is a certain proof of
their exactness.[13] Besides it is said, that one must make W.S.W., when
one has discerned Cape Blanco; and it is probable we had not got sight of
it in the evening, as was supposed. We therefore had an uncertain point of
departure;
