Eaft to Weft thro the midft of the IJIand, and that the 
Plantations on the South fide ot thefe hills have from 
iVbt^^/w^^r to a continual Summer, whilil thofe on 
thejNorth fide have as conftant a Winter,5c e contra from 
j4^rilto November. 
From thefe and fuch like accounts it feems evident 
that a bare lelfening of the^^;7^o/^/;^r^'s Gravity will not 
occafion rain, but that there is alfo needful! either a fud- 
den change of Winds, or a ridge of hills to meet the 
Current oi t\\Q Air and Vapours, whereby the Particles 
ot the Vapours are driven together and fo fall down into 
drops of rain. And hence it is that whilft the wind 
blows from the North-Eaft, vi^. from November to Aprils 
there are continual trains in the Northerly Plantations ot 
Jamaica and on the fide of Coromandel in the 1B.2L&-Indies, 
becaufe the winds beat againft that fide of the hills, and 
fo there is fair weather on the other fide of thefe hills, in 
Malabar, and the Southern Plantatiotis o£jamaica,thQrQ 
being no winds to drive the Vapours together. But in 
the Southerly Monfon , vi^» from April to November, 
Malabar, and the Southern Plantations <yf Jamaica have 
floods of rains, the wind beating againft that fide of the 
hills, whilft in Coromandel and the other fide of Jamaica 
there is fair and clear weather. The Maps make thofc 
Mountains oLGate run South and North, and if fo the 
Monfons muft blow from other points by reafonof the 
neighbouring Countries and IJlands^ or elfe this is not 
the truecaufe of thele feafons. 
This ferves aUo to clear the next thing mentioned,!//;^, 
the fingularity of feafons in Peru beyond any other parts 
of the Earth, and feems to be aflSgn d by Aco^la as the 
caufe of it. Peruxnn^ along from the Line Southwards 
about 1000 Leagues. It is laid to be divided into three 
parts, long, and narrow, which they call Lanos, Sierras 
and Andes-, the L^/zoj- or plains run along the South Sea
