All vessels bound for Dakar must await a pilot on the
parallel of Cape Manuel, and reduce speed when passing that
cape; passage northward of Gorée Island is entirely pro-
hibited.

Vessels requiring permission to enter must show their
national flag, indicate their number in the International Code,
and make the signal for a pilot.

Vessels must carefully comply with any orders signalled to
them from Cape Manuel. If no signal is made, vessels must
proceed at reduced speed towards the pilot sloop; the pilot
will then conduct them to the anchorage.

(2.) BY NIGHT.—Merchant vessels, by night, are only per-
mitted to enter the Port of Dakar in case of necessity. Mail
steamers may, however, demand entry at all hours, but are
subject to the same rules as other vessels with regard to
pilotage and examination.

Any vessel, by night, wishing to enter the port or to anchor
in the outer roadstead must approach with her navigation
lights distinctly visible, and show her flag. Vessels are to
stop one mile eastward of Cape Manuel and wait for the pilot
sloop. Vessels are prohibited from crossing the parallel of
Cape Manuel between the meridian of that cape and the
meridian of Gorée Island.

Any vessel wishing to anchor in the outer roadstead or to
enter the port must make her request for the pilot by show-
ing one or more white Bengal lights and by sounding her
whistle or siren.

After examination the vessel is to take up the anchorage
indicated by the pilot.

All vessels contravening the foregoing regulations will be
liable to be fired upon, in addition to punishment by law.
