124 CAUSE OF THE TKADE WINDS. 



LIB. in. vnder the Line or neere vnto it, with a continued and 

 durable season, it seemed to him to be the same aire, 

 mooved by the heaven the which guided the ships, and was 

 not properly a winde nor exhalation, but an aire moved with 

 the daily course of the sunne ; for proofe whereof he shewed 

 that the season is alwayes equall and alike at the gulph of 

 Damas, and in other great gulphes where wee saile vnder 

 the burning Zone, by reason whereof their sailes always 

 bear an equal strain, without its being needful to trim 

 them in all their voyage. And if the ayre were not 

 mooved by the heavens, it might sometimes faile, some 

 times change to the contrary, and sometimes there would 

 grow some stormes. Although this be learnedly spoken, 

 yet can we not deny it to be a winde, seeing there are 

 vapours and exhalations of the sea, and that we some 

 times see the Brisa or easterly winds stronger, some 

 times more weake, and placed in that sort as sometimes 

 they can hardly carry all their sailes. We must then know 

 (and it is true) that the aire mooved, draweth vnto it the 

 vapours it findes ; for that the force is great and findss no 

 resistance, by reason whereof the easterne and weasterne 

 windes are contiiiuall, and in a maner alwayes alike, in 

 those parts which are neere the Line, and almost vnder all 

 the burning zone, which is the cause the Sunne followes 

 betwixt the two circles of Cancer and Capricorne. 



CHAP. vn. Why without the Zone, in a greater altitude, u-ev 

 finde alwayes westerly windes. 



Whoso would neerely looke into what hath bin spoken 

 may likewise vnderstand that going from the west to the 

 east, in altitude beyond the Tropikes, we shall finde west- 

 erne windes, for that the motion of the Equinoctiall being 

 o swift, it is a cause that the ayre mooveth vnder it accord-
