To The
General Impulsion Which These Trade-Winds Give The Surface Of The
Sea, We Must Attribute The Equinoctial Current, The Force And
Rapidity Of Which Are Not Sensibly Modified By The Local Variations
Of The Atmosphere.
In the channel which the Atlantic has dug between Guiana and
Guinea, on the meridian of 20 or 23
Degrees, and from the 8th or
9th to the 2nd or 3rd degrees of northern latitude, where the
trade-winds are often interrupted by winds blowing from the south
and south-south-west, the equinoctial current is more inconstant in
its direction. Towards the coasts of Africa, vessels are drawn in
the direction of south-east; whilst towards the Bay of All Saints
and Cape St. Augustin, the coasts of which are dreaded by
navigators sailing towards the mouth of the Plata, the general
motion of the waters is masked by a particular current (the effects
of which extend from Cape St. Roche to the Isle of Trinidad)
running north-west with a mean velocity of a foot and a half every
second.
The equinoctial current is felt, though feebly, even beyond the
tropic of Cancer, in the 26th and 28th degrees of latitude. In the
vast basin of the Atlantic, at six or seven hundred leagues from
the coasts of Africa, vessels from Europe bound to the West Indies,
find their sailing accelerated before they reach the torrid zone.
More to the north, in 28 and 35 degrees, between the parallels of
Teneriffe and Ceuta, in 46 and 48 degrees of longitude, no constant
motion is observed:
