Winds will blow long, and make the Summers 
dry. 
But, on the contrary, when the Winter is mild, 
there are but a few of thofe Particles in North-Eurcpc , 
not enough to cool the Air there to fuch a Weight, as 
to enable it to hinder the South-weft from reaching 
us, even in Winter; and therefore, when once the 
Sun's Heat comes to deftroy thofe few, the South- 
weft, which is always ading with equal Force, pre- 
vails, and brings Rain in Summer. 
I make no doubt, but that a Courfe of Obferva- 
tions, kept for fome Years, in feveral Places, would 
reduce the Knowledge of thefe Viciftitudes of Wind 
and Weather to fome Certainty. 
I have taken notice only of Two Winds, the 
North- eaft and South weft, as the Producers of a long 
Run of dry or wet Weather: But if I have hit upon 
the true Caufes of thofe Winds, the fmaller Varia- 
tions may be eafily accounted for. I fhall mention a 
few. 
Next to thofe Two, the North- weft Wind blows 
longeft here, and with the greateft Force, but with 
various Effeds. Sometimes- it confpires with the 
South- weft, to blow a mere Storm, with hard Rain ; 
and fomettmes it takes part with the North eaft, blows 
dry, and freezes. We are, in a great meafure, be- 
holding to this Wind, for the little dry Weather we 
have in a mild Winter. 
I take this Wind to proceed from the Continent 
of North- America, where the Cold mijft needs be 
very intenfe, that can drive the Air from thence 
hither, with fuch ftrong Gufts. It .is well known, 
that Places of the fame Northern Latitude are much 
A a a a colder
