From the three last Observables is shewn the Reason of two notable Occurents in the _East-India_ and _Guinea_ Navigations: The one is, why, notwithstanding the narrowest part of the Sea between _Guinea_ and _Brazile_ be about five hundred Leagues over, yet Ships bound to the Southward, sometimes, especially in the Months of _July_ and _August_, find a great difficulty to pass it. This happens because of the South-East Winds, at that time of the Year commonly extending some Degrees beyond the ordinary limit of four Degrees North Latitude, and withal they come so much Southerly, as to be sometimes South, sometimes a Point or two to the West; there remains then only to ply to Windward, and if on the one side they stand away W. S. W. they gain the Wind still more and more Easterly; but there is danger of not weathering the _Brazilian_ Shoar, or at least the Shoals upon that Coast. But if upon the other Tack they go away E. S. E. they fall into the Neighbourhood of the Coast of _Guinea_, from which there is no departing without running Easterly, as far as the Isle of St. _Thomas_, which is the constant practice of all the _Guinea_ Ships, and which may seem very strange, without the consideration of the sixth Remark, which shews the Reason of it: For being in with the Coast, the Wind blows generally at S. W. and W. S. W. with which Winds they cannot go to the Northward for the Land; and on the other Tack they can lie no nearer the Wind than S. S. E. or South; with these Courses they run off the Shoar, but in so doing they always find the Winds more and more contrary; so that when near the Shoar they could lie South, at a greater distance they can make their way no better than S. E. and afterwards E. S. E. with which Courses they fetch commonly the Isle of St. _Thomas_ and Cape _Lopez_, where finding the Winds to the Eastward of the South, they keep them favourable, by running away to the Westward in the South Latitude, of three or four Degrees, where the S. E. Winds are perpetual. For the sake of these general Winds, all those that use the _West-Indian_ Trade, even those bound to _Virginia_, count it their best Course to get as soon as they can to the Southwards, that so they may be certain of a fair and fresh Gale to run before it to the Westwards; and for the same Reason those homewards bound from _America_, endeavour to gain the Latitude of thirty Degrees, as soon as possible, where they first find the Winds begin to be variable; tho' the most ordinary Winds in the Northern part of the _Atlantick_ Ocean come from between the South and West.
