AFRICA.
SOUTH COAST.--SPECIAL WARNING TO MARINERS.--CAUTION.

Mariners should remember that off all parts of the S. coast
of Africa, and especially off salient points, sunken wrecks or
uncharted dangers may exist close to the shore ; and that
it is not advisable to approach this surf-beaten shore, even in
full-power steam-vessels, within 3 or 4 miles. Sailing-vessels
should give Cape Agulhas a berth of 7 or 8 miles. When a
strong adverse current prevails, the temptation to approach
the shore is great, but wrd. of Algoa Bay there is nothing
to be gained by so doing, and in case of a breakdown of the
machinery or any temp. error in the course a risk is run of
total wreck before there is time or room to avoid such a
catastrophe. “Africa Pilot,” Part III, S. and E. coasts,
