 gius at the north, ^^j^^ south-wost wiuds are in equal conflict between 

 the parallels of 20° and 22° ; that in March the former have 

 been " backed down " (§ 684) as far as the parallel of 16°-15° — 

 the medial line between them from which each monsoon is 

 blowing — and where, again, the conflict of *' back to back " is 

 equally divided as to time of mastery (12 days) on either side. 

 By the month of June they (the south-west) have fairly gained 

 the ascendency, and so remain masters of the field until October, 

 when the bi-annual conflict is again commenced at the north. 

 The vanquished north-east trades now lead off in the attack, and, 

 as the Diagram C shows, the two combatants have force enough 



about the parallel of 15° north to blow during this month 9 days 

 each. The conflict, instead of being *'back to back," is now face 

 to face ; instead of blowing away from the medial line, they blow
