fhewingat one view all the various Trads and Courfes of 
tliefe Winds ; whereby 'tis poffible the thing may be bet- 
ter underftood, than by any verbal defcription whatfbever. 
The hmits of thefe feveral Tracts, are defigned every 
where by prickt lines, as well in the AtUnttck and jEtbiopick^ 
where they are the boundaries of the Trade and Variable 
Winds, as in the Indian Ocean, where they alfo fhew the ex- 
tent of the feveral Monfons. 1 could think of no better way 
to defign the courfe of the Winds on the Mapp, than by 
drawing rows of ftroaks in the fame line that a Ship would 
move going alwaies before it ; the lharp end of each little 
fti oak pointing out that part r f ts^e Horizon, from whence 
the Wind continually comes ; and where there are Monfoons 
th^ rows of the ftroaks run alternately backwards and for- 
wards, by which means they are thicker there than elfe- 
where. As to the great South Sea, confidering its vaft ex- 
tent, and the little Variety there is in its Winds, and the 
great Analogy between them, and thole of the Atlmtkk and 
JEthioftciz Oceans, befides that the greateft part thereof is' 
wholly unknown to us ; I thought it unneceflary to lengthen 
the Mapp therewith. 
In the foregoing Hiftory are contained feveral Problems;,

thele Win.is are perpetuaUy from the Eaft in the AtUntick 
and ALtmopick^ as likewife in tlie Factfck Ocean, between 
the Latitu jos of i^r North and 6buth. 2. Why the thefaid 
Winds extend no fartiier wich Conftancy than to the Lati- 
tudes of f ^4?- Why there ihould be a conftant South-
