For the fame Reafon we may fuppofe, that though 
the Eddy of the Trade wind fhouid be reflected due 
North, from the Land it firft ftrikes againft ; or even 
though it fhouid undergo as many Turnings as the 
Surface of the Sea it drives before it; yet it may take 
a new Dire&ion in the Ocean, caufed by the. Winds 
that blow from the Continent of North America. 
Another Obje&ion may be made againft the South- 
weft Wind being an Eddy of the Trade-wind, from 
what I myfelf have advanced, viz. that Cold is the 
Caufe of Wind: That th£" Atlantic Ocean is too 
warm to produce this Wind ; and yet that it comes 
from the Trade-wind, which blows between the 
Tropics, a Place much warmer: So that, according 
to this, here is a very warm Wind making its Way 
againft the Cold of the North. 
That Wind will blow from a warmer to a colder 
Quarter, is confirmed not only from the South-weft 
raging with us in Winter, which muft be confefted 
to come from a much warmer Climate, whatever 
Caufe it be owing to ; but from the almoft daily 
Obfervation of thofc who live in the Country, and 
will look a little about them. Whoever is within 
the Sight of Hills, and there are few Places where 
there are not fome in View, will find, if he takes 
the leaft Notice, that it rains in the Hills before it 
rains in the Vales : What can be the Caufe of this 
Rain? Nothing, doubtlefs, but a Wind blowing from 
the Vales towards the Hills; that is, from a warmer 
to a colder Region, where the Vapour, which is 
brought thither, falls. Suppofe the Air over the 
Hills be cold in 20 Degrees, and the Air over the 
Vales but in 10 Degrees, 10 cannot outweigh 2c.; 
but,,
