OF WINDS. 277 



and by little and little they allay ; and contrariwise, where 

 they find good store of matter to feed on by the way, they 

 are weak in the beginning, but gather strength by the way. 



7. There are moveable nurseries for the winds, namely, 

 in the clouds, which many times are carried far away from 

 the nurseries of vapours of which those clouds were made, 

 by winds blowing high ; then the nursery of the wind be 

 gins to be in that place where the clouds do begin to be 

 dissolved into wind. 



8. But the whirling of winds does not happen, because 

 the wind which blows at first transports itself, but because 

 either that is allayed and spent, or brought into order by 

 another wind ; and all this business depends on the various 

 placings of the nurseries of winds, and variety of times, 

 when vapours issuing out of these nurseries are dissolved. 



9. If there be nurseries of winds on contrary parts, as 

 one nursery on the south, another on the north side, the 

 strongest wind will prevail ; neither will there be contrary 

 winds, but the stronger wind will blow continually, though 

 it be somewhat dulled and tamed by the weaker wind, as 

 it is in rivers, when the flowing of the sea comes in ; for 

 the sea s motion prevails, and is the only one, but it is 

 somewhat curbed by the motion of the river ; and if it so 

 happen that one of those contrary winds, namely, that 

 which was the strongest be allayed, then presently the 

 contrary will blow, from that side where it blew before, but 

 lay hidden under the force and power of the greater. 



10. As for example, if the nursery be at the north-east, 

 the north-east wind will blow ; but if there be two nurseries 

 of winds, namely, another in the north, those winds for 

 some tract of way will blow severally, but after the angle 

 of confluence where they come together they will blow to 

 the north-east, or with some inclination, according as the 

 other nursery shall prove stronger. 



11. If there be a nursery of wind on the north side, 

 which may be distant from some country twenty miles, 

 and is the stronger; another on the east side, which is dis 

 tant some ten miles, and is weaker ; yet the east wind shall 

 blow for some hours, and a while after (namely, when its 

 journey is ended) the north wind. 



12. If the northern wind blow, and some hill stands in 

 the way of it on the west side, a little while after the north 

 east wind will blow, compounded by the original, and that 

 which is beaten back again. 



13. If there be a nursery of winds in the earth on the
